Equinoxes occur twice yearly when the sun is directly above the equator and day and night are approximately equal in length. Solstices occur twice yearly when the sun reaches its highest or lowest point in the sky, resulting in the longest and shortest days of the year in the summer and winter respectively in each hemisphere. The document then provides details on the timing and effects of the summer and winter solstices and spring and autumnal equinoxes in both hemispheres.
A "lunar eclipse" and a "solar eclipse" refer to events involving three celestial bodies: the Sun ("solar"), the moon ("lunar"), and the Earth. A lunar eclipse occurs when the Earth passes between the Moon and the Sun, and the Earth's shadow obscures the moon or a portion of it. A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking all or a portion of the Sun.

Seasons are divisions of the year marked by distinct weather patterns, changes in temperature, and variations in daylight hours. They are primarily determined by the Earth's axial tilt and its orbit around the Sun. The four main seasons recognized in many regions of the world are spring, summer, autumn (fall), and winter. Here's a brief description of each season:
1. Spring: Spring is the season that follows winter and precedes summer. It is characterized by gradually increasing temperatures, longer daylight hours, and the emergence of new plant growth. In many places, spring is associated with blooming flowers, budding trees, and the return of various animal species.
2. Summer: Summer is the warmest season of the year. It is marked by higher temperatures, extended daylight hours, and generally favorable weather conditions. Summer is often associated with vacations, outdoor activities, and the opportunity to enjoy beaches, swimming, picnics, and various recreational pursuits.
3. Autumn (Fall): Autumn, also known as fall, is the season that follows summer and precedes winter. It is characterized by cooler temperatures, shorter daylight hours, and the shedding of leaves from deciduous trees. Autumn is often associated with vibrant foliage, harvest festivals, and a gradual transition towards colder weather.
4. Winter: Winter is the coldest season of the year. It is marked by low temperatures, shorter daylight hours, and, in many regions, the presence of snow and ice. Winter is often associated with holidays such as Christmas and New Year's, as well as activities like skiing, snowboarding, ice skating, and cozy indoor pursuits.
It's important to note that the timing and characteristics of seasons can vary depending on the geographical location, as well as regional climatic conditions.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
2. Equinox
An astronomical event that happens twice, once in spring
and once in autumn each year when the tilt of the Earth's
axis is inclined neither away from nor towards the Sun
During Equinoxes the tilt of the Earth (with respect to the
Sun) is 0° and because of it duration of the day and the
night are almost equal on Equinox day i.e. 12 hours
Equinoxes occur on 20th or 21st March and 22nd or
23rd September each year and both days has equal length of
the day and the night.
3. Solstice - solstitium meaning “sun stopping”
an astronomical event that happens twice, once in summer and
once in winter, each year when the Sun reaches its highest
position in the sky as seen from the North or South Pole
During Solstices the tilt of the axil of the Earth (with respect to
the Sun) is the maximum at 23° 26'.
Solstices are preferably referred as June Solstice (Northern
Solstice) and December Solstice (Southern Solstice)
Solstices occur on 20th or 21st June and 21st or 22nd December each year.
During summer the day of the solstice is the longest day of the year and
during winter the day of the solstice is the shortest day of the year
4.
5.
6. The first day of the Season of
Summer (JUNE 21)
hours of daylight are increased
in the northern hemisphere, the Sun
is farthest north and the length of
time between Sunrise and Sunset is
the longest of the year
The sun rises to the north of east, sets
to the north of west
the sun is visible in the sky for a longer
period
SUMMER SOLSTICE
It's also known as the northern solstice because it occurs when the sun is
directly over the Tropic of Cancer in the Northern Hemisphere
7. during June Solstice it is summer time in
the UK, the USA, Canada, Russia, India
and China and it is the longest day of the
year while it is winter time in Australia,
Argentina, Chile, New Zealand and South
Africa and it is the shortest day of the year
8. Midnight Sun or Polar Night?
On the June solstice, the midnight sun is visible
(weather permitting) throughout the night, in all areas
from just south of the Arctic Circle to the North Pole.
Sunrise and Sunset Times
On the other side of the planet, south of the Antarctic
Circle there's Polar Night, meaning no Sunlight at all,
on the June Solstice
9. Solstice Dates Vary
it can happen anytime between June 20 and June 22, depending on which time
zone you're in
June 22 Solstices are rare - the last June 22 Solstice took place in 1975 and
there won't be another one until 2203
The varying dates of the solstice are mainly due to the calendar system – most
western countries use the Gregorian calendar which has 365 days in a normal
year and 366 days in a Leap Year
A tropical year, the time it takes the Earth to orbit the Sun completely, is ca.
365.242199 days, but varies slightly from year to year because of the
influence of other planets. The exact orbital and daily rotational motion of the
Earth, such as the “wobble” in the Earth's axis (precession of the equinoxes),
also contributes to the changing solstice dates
10. WINTER SOLSTICE
The first day of the Season of
Winter
DECEMBER 21
in the northern hemisphere,
the Sun is farthest south and
the length of time between
Sunrise and Sunset is the
shortest of the year
hours of daylight are decreased
during December Solstice, it is
winter time in the UK, the USA,
Canada, Russia, India and China
and it is the shortest day of the
year while it is summer time in
Australia, Argentina, Chile, New
Zealand and South Africa and it is
the longest day of the year
11. VERNAL EQUINOX
The first day of the Season of Spring - and the beginning of a long
period of sunlight at the Pole
In the northern hemisphere: MARCH 20 (the Sun crosses the Equator
moving northward)
In the southern hemisphere: SEPTEMBER 22 (the Sun crosses the
Equator moving southward).
12. On March Equinox, it is spring time in
the UK, the USA, Canada, Russia,
India and China while it is autumn
time in Australia, Argentina, Chile,
New Zealand and South Africa
13. AUTUMN EQUINOX
The first day of the Season of Autumn - and the beginning of a long
period of darkness at the Pole.
In the northern hemisphere: SEPTEMBER 22 (the Sun crosses the
Equator moving southward)
In the southern hemisphere: MARCH 20 (the Sun crosses the Equator
moving northward).
14. Earth does not move at a constant speed in its elliptical orbit.
Therefore the seasons are not of equal length: the times taken for the
sun to move from the March Equinox to the June Solstice, to the
September equinox, to the December solstice, and back to the March
equinox are roughly 92.8, 93.6, 89.8 and 89.0 days respectively
The consolation in the Northern Hemisphere is that spring and
summer last longer than autumn and winter
15. After the June solstice, the sun follows a lower and lower path
through the sky each day in the Northern Hemisphere until it
reaches the point where the length of daylight is about 12 hours
and eight to nine minutes in areas that are about 30 degrees
north or south of the equator
Areas 60 degrees north or south of the equator have daylight for
about 12 hours and 16 minutes. This is the September Equinox,
the Autumnal Equinox in the Northern Hemisphere
on September Equinox it is autumn time in the UK, the USA,
Canada, Russia, India and China while it is spring time in
Australia, Argentina, Chile, New Zealand and South Africa
16. on September Equinox, it is autumn time in
the UK, the USA, Canada, Russia, India and
China while it is spring time in Australia,
Argentina, Chile, New Zealand and South
Africa
Editor's Notes
Vernal – sun hits directly the equator, sun shines equally both in south and north hemisphere
Winter – sun rises and sets furthest north along the horizon
Summer – highest point north of the equator
Autumn – the sun shines directly across from the equator perpendicular to the surface of the earth
- Sunlight equally shines in the northern and southern hemisphere
