The Next Generation Transit Survey (NGTS)Sérgio Sacani
We describe the Next Generation Transit Survey (NGTS), which is a ground-based
project searching for transiting exoplanets orbiting bright stars. NGTS builds on the
legacy of previous surveys, most notably WASP, and is designed to achieve higher
photometric precision and hence find smaller planets than have previously been de-
tected from the ground. It also operates in red light, maximising sensitivity to late
K and early M dwarf stars. The survey specifications call for photometric precision
of 0.1 per cent in red light over an instantaneous field of view of 100 square degrees,
enabling the detection of Neptune-sized exoplanets around Sun-like stars and super-
Earths around M dwarfs. The survey is carried out with a purpose-built facility at
Cerro Paranal, Chile, which is the premier site of the European Southern Observatory
(ESO). An array of twelve 20 cm f/2.8 telescopes fitted with back-illuminated deep-
depletion CCD cameras are used to survey fields intensively at intermediate Galactic
latitudes. The instrument is also ideally suited to ground-based photometric follow-up
of exoplanet candidates from space telescopes such as Gaia, TESS and PLATO. We
present observations that combine precise autoguiding and the superb observing con-
ditions at Paranal to provide routine photometric precision of 0.1 per cent in 1 hour
for stars with I-band magnitudes brighter than 13. We describe the instrument and
data analysis methods as well as the status of the survey, which achieved first light
in 2015 and began full survey operations in 2016. NGTS data will be made publicly
available through the ESO archive.
NGTS-1b: A hot Jupiter transiting an M-dwarfSérgio Sacani
We present the discovery of NGTS-1b, a hot-Jupiter transiting an early M-dwarf
host (Teff,∗=3916 +71
−63 K) in a P = 2.647 d orbit discovered as part of the Next Generation
Transit Survey (NGTS). The planet has a mass of 0.812 +0.066
−0.075MJ and radius
of 1.33 +0.61
−0.33 RJ , making it the largest and most massive planet discovered transiting
any M-dwarf. NGTS-1b is the third transiting giant planet found around an M-dwarf,
reinforcing the notion that close-in gas giants can form and migrate similar to the
known population of hot Jupiters around solar type stars. The host star shows no
signs of activity, and the kinematics hint at the star being from the thick disk population.
With a deep (2.5%) transit around a K = 11.9 host, NGTS-1b will be a strong
candidate to probe giant planet composition around M-dwarfs via JWST transmission
spectroscopy.
Science is the systematic study of the physical and natural world through observation and experimentation. In 2016, scientists Mike Brown and Konstantin Batygin at Caltech announced evidence for a potential giant planet in the outer solar system nicknamed "Planet Nine" estimated to be about 10 times Earth's mass and take between 10,000 to 20,000 years to orbit the sun, though it has yet to be directly observed. Some famous scientists include Albert Einstein, Isaac Newton, Louis Pasteur, Marie Curie, Aristotle, and Carl Linnaeus.
Neowise observations of near earth objects- preliminary resultsSérgio Sacani
The NEOWISE survey observed near-Earth objects at infrared wavelengths, detecting over 130 new NEOs. Analysis of the 428 NEOs detected allows estimates of the total NEO population between 100m and 1km in size. The survey found an estimated 981±19 NEOs larger than 1km have been detected, meeting the Spaceguard goal of detecting 90% of objects this size. It also estimates 20,500±3000 NEOs larger than 100m. The cumulative size distribution is best represented by a broken power law.

Alfvénic velocity spikes and rotational flows in the near-Sun solar windSérgio Sacani
The prediction of a supersonic solar wind1
was frst confrmed by spacecraft near
Earth2,3
and later by spacecraft at heliocentric distances as small as 62 solar radii4
.
These missions showed that plasma accelerates as it emerges from the corona, aided
by unidentifed processes that transport energy outwards from the Sun before
depositing it in the wind. Alfvénic fuctuations are a promising candidate for such a
process because they are seen in the corona and solar wind and contain considerable
energy5–7
. Magnetic tension forces the corona to co-rotate with the Sun, but any
residual rotation far from the Sun reported until now has been much smaller than the
amplitude of waves and defections from interacting wind streams8
. Here we report
observations of solar-wind plasma at heliocentric distances of about 35 solar radii9–11,
well within the distance at which stream interactions become important. We fnd that
Alfvén waves organize into structured velocity spikes with duration of up to minutes,
which are associated with propagating S-like bends in the magnetic-feld lines. We
detect an increasing rotational component to the fow velocity of the solar wind
around the Sun, peaking at 35 to 50 kilometres per second—considerably above the
amplitude of the waves. These fows exceed classical velocity predictions of a few
kilometres per second, challenging models of circulation in the corona and calling
into question our understanding of how stars lose angular momentum and spin down
as they age12–14.

Delivery of dark_material_to_vesta_via_carbonaceous_chondritic_impactsSérgio Sacani
This document analyzes dark material (DM) observed on the surface of asteroid Vesta by NASA's Dawn spacecraft. Spectral analysis finds the DM has properties similar to carbonaceous chondrite meteorites mixed with Vestan surface materials. Laboratory experiments matching the albedo and absorption bands of DM used mixtures of carbonaceous chondrites and eucrite basalt. Impact modeling suggests the DM was delivered via impacts of carbonaceous chondrite asteroids during the formation of the large Veneneia impact basin on Vesta. This supports the idea that carbonaceous chondrites were an important early source of carbon and volatiles in the solar system.
Louise Riofrio talks on the Speed of LightILOAHawaii
The document discusses the history of cosmological theories from an Earth-centered model to a Sun-centered model proposed by Copernicus to the modern Big Bang theory. It also proposes that a simple equation, GM=tc^3, may help solve problems in cosmology such as the lunar orbit anomaly and observations of distant supernovae. Future experiments like the Atomic Clock Ensemble in Space could help test predictions of a changing speed of light from the proposed equation.

This summarizes a scientific study on long-distance quantum teleportation between two laboratories separated by 55 meters but connected by 2 kilometers of fiber optic cable. The key points are:
1) Researchers teleported quantum states (qubits) carried by photons at 1.3 micrometer wavelengths onto photons at 1.55 micrometer wavelengths between the two laboratories.
2) The qubits were encoded in time-bin superpositions and entanglement rather than polarization to make them more robust against decoherence in optical fibers.
3) A partial Bell state measurement was performed using linear optics at the receiving end to probabilistically teleport the quantum states over the long distance.

A candidate super-Earth planet orbiting near the snow line of Barnard’s starSérgio Sacani
This document summarizes the discovery of a candidate super-Earth planet orbiting Barnard's star. Analysis of over 20 years of radial velocity measurements revealed a periodic signal of 233 days, attributed to a planet with a minimum mass of 3.2 Earth masses in a near-circular orbit near the star's snow line. Long-term monitoring also detected a possible second signal with a period over 6,000 days, which could be from a more distant planet or stellar magnetic activity cycle. Independent photometric and spectroscopic monitoring ruled out stellar activity as the cause of the 233-day signal. This candidate planet has one of the lowest minimum masses detected around an M dwarf star.
This document presents an analysis of transit spectroscopy observations of three exoplanets - WASP-12 b, WASP-17 b, and WASP-19 b - using the Wide Field Camera 3 instrument on the Hubble Space Telescope. The observations achieved almost photon-limited precision but uncertainties in the transit depths were increased by the uneven sampling of the light curves. The final transit spectra for all three planets are consistent with the presence of a water absorption feature at 1.4 microns, though the amplitude is smaller than expected from previous Spitzer observations possibly due to hazes. Due to degeneracies between models, the data cannot unambiguously constrain the atmospheric compositions without additional observations.
The document discusses the 25th anniversary of the Hubble Space Telescope and how NASA's Goddard Space Flight Center celebrated. It provides details on events held at the Newseum in Washington D.C. and tours given at Goddard, highlighting Hubble's scientific achievements. Goddard leads Hubble operations and was instrumental in its development and ongoing missions. The anniversary is an opportunity to look to the future James Webb Space Telescope, intended to further discoveries beyond what Hubble can achieve.
The Second Data Release of the INT Photometric Hα Survey of the Northern Galactic Plane (IPHAS) provides single-epoch photometry for 219 million unique sources across 92% of the survey's footprint. The survey used the Wide Field Camera on the Isaac Newton Telescope to image a region of the northern Galactic plane in Sloan r, i, and narrowband Hα filters between 2003-2012. The data were reduced and calibrated using procedures developed for the INT Wide Field Survey. A global re-calibration was performed using the AAVSO Photometric All-Sky Survey and the Sloan Digital Sky Survey, achieving an accuracy of 0.03 mag. The catalogue characterizes stellar populations and extinction across different Galactic sightlines and
Two temperate Earth-mass planets orbiting the nearby star GJ 1002Sérgio Sacani
We report the discovery and characterisation of two Earth-mass planets orbiting in the habitable zone of the nearby M-dwarf GJ 1002 based on
the analysis of the radial-velocity (RV) time series from the ESPRESSO and CARMENES spectrographs. The host star is the quiet M5.5 V star
GJ 1002 (relatively faint in the optical, V ∼ 13.8 mag, but brighter in the infrared, J ∼ 8.3 mag), located at 4.84 pc from the Sun.
We analyse 139 spectroscopic observations taken between 2017 and 2021. We performed a joint analysis of the time series of the RV and full-width
half maximum (FWHM) of the cross-correlation function (CCF) to model the planetary and stellar signals present in the data, applying Gaussian
process regression to deal with the stellar activity.
We detect the signal of two planets orbiting GJ 1002. GJ 1002 b is a planet with a minimum mass mp sin i of 1.08 ± 0.13 M⊕ with an orbital period
of 10.3465 ± 0.0027 days at a distance of 0.0457 ± 0.0013 au from its parent star, receiving an estimated stellar flux of 0.67 F⊕. GJ 1002 c is a
planet with a minimum mass mp sin i of 1.36 ± 0.17 M⊕ with an orbital period of 20.202 ± 0.013 days at a distance of 0.0738 ± 0.0021 au from
its parent star, receiving an estimated stellar flux of 0.257 F⊕. We also detect the rotation signature of the star, with a period of 126 ± 15 days. We
find that there is a correlation between the temperature of certain optical elements in the spectrographs and changes in the instrumental profile that
can affect the scientific data, showing a seasonal behaviour that creates spurious signals at periods longer than ∼ 200 days.
GJ 1002 is one of the few known nearby systems with planets that could potentially host habitable environments. The closeness of the host star
to the Sun makes the angular sizes of the orbits of both planets (∼ 9.7 mas and ∼ 15.7 mas, respectively) large enough for their atmosphere to be
studied via high-contrast high-resolution spectroscopy with instruments such as the future spectrograph ANDES for the ELT or the LIFE mission.
Science and challenges of lunar sample return workshop estec february 2014Dinis Ribeiro
The Moon is an important exploration destination for ESA and is considered to be the next destination for humans beyond Low Earth Orbit.
European access to the lunar surface is most likely to be made through cooperation with international partners and opportunities for international cooperation in the broad area of lunar exploration are being investigated .
Sample return missions are an important element in the future cooperative exploration scenarios under discussion, as a next step after surface missions. They are a means of building international partnerships, developing and demonstrating technologies and capabilities, and performing detailed analyses to answer fundamental scientific questions and address exploration enabling knowledge gaps through analyses which cannot be performed in situ. Such missions may be required to access extreme environments, perform complex surface operations, and handle uniquely demanding sample requirements. Such activities can result in major advances in planetary sciences, astrobiology and the future of exploration.
A Lunar Polar Sample Return mission, envisaged in the early 2020s by Roscosmos, has been identified by ESA as an important cooperative mission opportunity, and as a logical follow-on from a possible European participation to the Luna-Resurs Lander mission planned by Roscosmos before the end of this decade. In addition a human tended deep space capability, as initiated with the Orion vehicle currently developed by NASA in cooperation with ESA, can be of benefit to a sample return mission and may lead to a future integration of robotic and human exploration.
In preparation for these missions it is important to review our current knowledge and understanding of the Moon, establish the scientific and technical goals that should be targeted and the associated challenges that lie ahead. This workshop will explore the possible benefits and scientific return from Lunar Sample Return missions and investigate the implications for future mission systems.
Objectives
The workshop is being organised to gather information and opinions from stakeholders in the science and technology communities to inform future studies into lunar sample return missions, most likely to be considered in the frame of international partnerships. The inputs will be considered by the ESA Lunar Sample Return Science Definition Team and used as inputs for a Science Definition and Requirements Document which will be used to inform future ESA activities in this area.
The key objectives are to identify:
Ways in which Lunar Sample Return will support preparations for future exploration activities
Scientific priorities and competencies for the analysis of samples and to define objectives for sample return missions
Mission requirements that these objectives impose on missions
Technical challenges of meeting these requirements and potential solutions
This study examines a reservoir of ionized gas in the galactic halo that can sustain star formation in the Milky Way. The authors detect a substantial amount of warm-hot gas in the halo of a star-forming galaxy at z=0.2 through detection of Ne VIII absorption lines. This warm-hot gas reservoir contains as much mass as the galaxy's stars and can replenish its supply of cool gas to sustain star formation over billions of years.
Discovery and properties of the earliest galaxies with confirmed distancesSérgio Sacani
Surveys with James Webb Space Telescope (JWST) have discovered candidate galaxies in
the first 400 Myr of cosmic time1-5
. The properties of these distant galaxies provide initial
conditions for understanding early galaxy formation and cosmic reionisation6
. Preliminary
indications have suggested these candidate galaxies may be more massive and abundant
than previously thought1,7-9
. However, without spectroscopic confirmation of their
distances to constrain their intrinsic brightnesses, their inferred properties remain
uncertain. Here we report on four galaxies located in the JWST Advanced Deep
Extragalactic Survey (JADES) Near-Infrared Camera (NIRCam) imaging with
photometric redshifts � ∼ �� − �� subsequently confirmed by JADES JWST NearInfrared Spectrograph (NIRSpec) observations10. These galaxies include the first redshift
� > �� systems both discovered and spectroscopically confirmed by JWST. Using stellar
population modelling, we find the galaxies typically contain a hundred million solar masses
in stars, in stellar populations that are less than one hundred million years old. The
moderate star formation rates and compact sizes suggest elevated star formation rate
surface densities, a key indicator of their formation pathways. Taken together, these
measurements show that the first galaxies contributing to cosmic reionisation formed
rapidly and with intense internal radiation fields.
A dynamically packed_planetary _system_around_gj667_c_with_three_superearths_...Sérgio Sacani
This document summarizes the discovery of six potentially habitable super-Earth planets orbiting the red dwarf star GJ 667C. Analyzing new Doppler measurements from HARPS and previous data from other spectrographs, the authors detect six planetary candidates with orbital periods of 7, 28, 92, 62, 39, and 260 days. They validate the signals against stellar activity and find the system could be dynamically stable. Three or four of the planets may be located within the star's habitable zone where liquid water could exist, making this one of the first exoplanetary systems discovered with multiple Earth-sized planets in the habitable zone of an M-dwarf star.
AT 2022aedm and a New Class of Luminous, Fast-cooling Transients in Elliptica...Sérgio Sacani
This document reports the discovery and follow-up observations of a remarkable fast-evolving optical transient called AT 2022aedm. Key points:
- AT 2022aedm was discovered by the ATLAS survey and reached an extremely luminous peak magnitude of Mg ≈ -22 mag.
- It exhibited an unusually fast rise time of 9 days and faded by 2 magnitudes in the following 15 days.
- Most surprisingly, its host galaxy was found to be a massive elliptical galaxy with negligible star formation.
- Extensive follow-up observations including spectroscopy found it shared properties with two other similar transients in passive galaxies, suggesting a new class of "luminous fast coolers." However
The Variable Detection of Atmospheric Escape around the Young, Hot Neptune AU...Sérgio Sacani
This document summarizes observations from the Hubble Space Telescope of the young hot Neptune exoplanet AU Mic b, which orbits the nearby M dwarf star AU Mic. The observations aimed to detect atmospheric escape of neutral hydrogen through absorption in the stellar Lyman-alpha emission line. Two visits were obtained, one in 2020 and one in 2021, corresponding to transits of the planet. A stellar flare was observed and removed from the first visit data. In the second visit, absorption was detected in the blue wing of the Lyman-alpha line 2.5 hours before the white light transit, indicating the presence of high-velocity neutral hydrogen escaping the planet's atmosphere and traveling toward the observer. Estimates place the column density of this material

This document presents the first results from the JWST XUE program, which observed 15 protoplanetary disks in the NGC 6357 star-forming region using MIRI. For the disk XUE 1, located near massive stars, the following was found:
1) Abundant water, CO, CO2, HCN, and C2H2 were detected in the inner few AU, indicating an oxygen-dominated gas-phase chemistry similar to isolated disks.
2) Small crystalline silicate dust is present at the disk surface.
3) The column densities and chemistry are surprisingly similar to isolated disks despite the extreme radiation environment, implying inner disks can retain conditions conducive to rocky planet
Deja vu all_over_again_the_reapperance_of_supernova_refsdalSérgio Sacani
O Telescópio Espacial Hubble das agências NASA e ESA registrou a imagem pela primeira vez da explosão prevista de uma supernova. O reaparecimento da supernova Refsdal foi calculado a partir de diferentes modelos de aglomerados de galáxias, cuja imensa gravidade está entortando a luz da supernova.
Muitas estrelas terminam a sua vida com uma explosão, mas somente poucas dessas explosões estelares têm sido registradas no ato que acontecem. Quando isso acontece, é pura sorte, pelo menos até agora. No dia 11 de Dezembro de 2015, os astrônomos não somente fizeram a imagem de uma supernova em ação, como também observaram quando e onde ela estava prevista para acontecer.
A supernova, apelidada de Refsdal, foi registrada no aglomerado de galáxias, conhecido como MACS J1149.5+2223. Enquanto que a luz do aglomerado gasta cerca de cinco bilhões de anos para chegar até nós, a supernova explodiu muito tempo antes, a aproximadamente 10 bilhões de anos atrás.
A história da Refsdal começou em Novembro de 2014, quando os cientistas registraram quatro imagens separadas da supernova num raro arranjo conhecido como Cruz de Einstein, ao redor de uma galáxia dentro do MACS J1149.5+2223. A ilusão de óptica cósmica ocorreu devido ao fato da massa de uma única galáxia dentro do aglomerado estar entortando e ampliando a luz da distante explosão estelar, num processo conhecido como lente gravitacional.
Artigo que descreve a descoberta do exoplaneta Kepler-432b, um exoplaneta mais massivo que Júpiter que orbita uma estrela gigante vermelha bem próximo e numa órbita extremamente alongada.
The document summarizes the goals and achievements of the European Space Agency (ESA) in international space cooperation. It discusses ESA's cooperation with NASA on past and future space missions. It also outlines ESA's goals in areas like solar system exploration, fundamental physics and cosmology, exoplanet research, space science, earth observation, human spaceflight, and international space station utilization over the next decades.
We present the 2020 version of the Siena Galaxy Atlas (SGA-2020), a multiwavelength optical and infrared
imaging atlas of 383,620 nearby galaxies. The SGA-2020 uses optical grz imaging over ≈20,000 deg2 from the
Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Surveys Data Release 9 and infrared imaging in
four bands (spanning 3.4–22 μm) from the 6 year unWISE coadds; it is more than 95% complete for galaxies larger
than R(26) ≈ 25″ and r < 18 measured at the 26 mag arcsec−2 isophote in the r band. The atlas delivers precise
coordinates, multiwavelength mosaics, azimuthally averaged optical surface-brightness profiles, model images and
photometry, and additional ancillary metadata for the full sample. Coupled with existing and forthcoming optical
spectroscopy from the DESI, the SGA-2020 will facilitate new detailed studies of the star formation and mass
assembly histories of nearby galaxies; enable precise measurements of the local velocity field via the Tully–Fisher
and fundamental plane relations; serve as a reference sample of lasting legacy value for time-domain and
multimessenger astronomical events; and more.
Observation of large scale precursor correlations between cosmic rays and ear...Sérgio Sacani
The search for correlations between secondary cosmic ray detection rates and seismic
effects has long been a subject of investigation motivated by the hope of identifying a new
precursor type that could feed a global early warning system against earthquakes. Here we show
for the first time that the average variation of the cosmic ray detection rates correlates with the
global seismic activity to be observed with a time lag of approximately two weeks, and that the
significance of the effect varies with a periodicity resembling the undecenal solar cycle, with a
shift in phase of around three years, exceeding 6 𝜎 at local maxima. The precursor characteristics
of the observed correlations point to a pioneer perspective of an early warning system against
earthquakes.
