The Voyager flights to Jupiter and Saturn were NASA missions launched in 1977 that took advantage of a rare planetary alignment to visit multiple outer planets using gravitational assists. Voyager 1 and 2 were each complex, long-lived spacecraft carrying instruments to study the planets, rings, moons, and environments. Voyager 1's encounter with Jupiter in 1979 revealed active volcanoes on Io and details of Jupiter's atmosphere, while both probes provided the first close images of Jupiter's moons."
This document provides a visualization of distances from Earth as they increase exponentially from 1 meter to 100 million light years. At each order of magnitude, a brief description is given of what can be seen from that distance, starting with leaves close up and progressing out to views of the Milky Way galaxy and beyond. The scale of the distances involved and perspective of Earth and the solar system become increasingly small as the distance grows enormously large.
The document discusses how viewing images from space, such as those taken by the Hubble telescope, can help put life's problems into perspective by showing how small and insignificant individual problems are in the grand scheme of the vast universe. Some of the key images highlighted include galaxies, nebulae, planets in our solar system, and images of Earth from space that illustrate our planet's fragility. The overall message is that contemplating images of the immense cosmos can provide a sense of humility about human problems and importance of protecting our small home of Earth.

Presentasi Sistem Tata SuryaㅡSolar System ExplanationIka
The solar system formed over 4.6 billion years ago from a dense cloud of gas and dust that collapsed under its own gravity. As the central mass condensed to form the sun, the surrounding matter began to clump together through collisions to create the planets. The planets follow elliptical orbits around the sun, trapped by its strong gravitational pull along with other celestial bodies like asteroids, comets and moons. Our solar system resides within the Milky Way galaxy.

In February, 2017 the Space Horizons workshop at Brown University focused on sending spacecraft to the Alpha Centauri stellar / planetary system. The first questions that come to mind include: getting there in some relevant amount of time, i.e. less than a human lifespan; communicating back over the 4+ light years distance; surviving the space environment en route; What do you do when you get there, and; how much is all that going to cost?
We also asked: what could we learn by going there vs. wouldn’t we learn more directing those resources to developing instruments here in the earth and near-earth environment to observe the star system (and probably other star systems) and exoplanets remotely? Would going there have some special meaning to people on earth as America’s landing of people on the moon did, versus the Soviet robotic missions? And what might we learn along the way - thinking our way to another star - that might change how we do other possibly completely unrelated things - closer to home?
We barely managed to even address all those questions in a day and a half at Brown, but undaunted I will do the best I can to distill that concentrated dose of interstellar travel down another factor of 30 into a talk 0.0014% of the trip time to Alpha Centauri at the speed of light. I.e. 30 minutes.
Habiatal Zone (outside our solar system)Bob Smullen
The document discusses the habitability of planets outside our solar system. It covers topics like the habitable zones around different types of stars where liquid water could exist, methods used to detect exoplanets, and factors that influence a planet's potential habitability such as size, atmosphere, and distance from the host star. It also examines probabilities for life elsewhere in the galaxy based on the Drake Equation and considers challenges around detecting and communicating with intelligent civilizations.

This document provides an introduction and overview for the role-playing game Metamorphosis Alpha. It describes the setting as a massive generation starship called the Warden that suffered radiation damage, causing the ship and its inhabitants to mutate and regress to a primitive state. The ship is described as 50 miles long containing 17 levels, with examples given of the types of facilities and environments contained on different levels, including stores of supplies and materials, forests, factories, and more. The goal of the game is for players to take on roles in this mutated environment and survive by exploring the ship and gaining knowledge and technology.
This document discusses several topics from science and the Quran:
1) It describes the life cycle of stars and what happens when they run out of nuclear fuel and collapse, forming black holes.
2) It discusses the expansion of the universe from the Big Bang theory and how galaxies have red shifts showing they are moving farther away over time.
3) It mentions several scientific discoveries throughout history about human development from a sperm and egg and the stages of formation in the womb, noting many of these details were described in the Quran centuries before their scientific discovery.
This document discusses the immense scale and complexity of the universe, from galaxies and clusters containing trillions of stars, to our own solar system and planet Earth. It notes how perfectly Earth's atmosphere, size, and placement in the solar system support life, defying chances against it. Even more complex are the human body's cells, DNA, and structures like laminin that reveal masterful design beyond what science can explain. The document aims to inspire awe at the Creator's handiwork in the universe and in human life.
The documentary Triumph of the Dream explores the human story behind NASA's Mars Exploration Rover mission that landed two rovers on Mars in 2004. Award-winning photographer Norman Seeff was invited to document the mission and developed a narrative structure based on the seven stages of the creative process. The film reveals how scientists at NASA's Jet Propulsion Laboratory worked to advance our understanding of Mars as a potentially habitable planet in the past through the rovers' analysis of rocks and soil. Seeff believes it is important to share the experience of the mission with the public who funded it and to spark interest in space exploration, environmentalism, and discovery.
The document discusses the occupational characteristics of microbiologists. Microbiologists study microorganisms like bacteria, archaea, algae, fungi, protozoa and viruses. On a daily basis, microbiologists treat infections, identify and classify new organisms, and find new uses for existing organisms. They may also work in epidemiology and write research reports. Graduating with a biology degree from the University at Albany provides various career opportunities in fields like research, health, and education, including work as a microbiologist.
“Poets say science takes away from the beauty of the stars - mere globs of gas atoms. I, too, can see the stars on a desert night, and feel them. But do I see less or more?” - Richard P. Feynman
We all have wondered about the origins of our universe. How did it all begin? What do we see when we look up at the night sky? What exactly is dark matter? Are there more universes out there? What about aliens?
Jaya — a student of astronomy — is on her way to discovering the answers to these questions and unravelling other mysteries of our universe. She’s here this weekend to share what she’s learnt so far with us.
Date: Saturday, January 8, 2011
Time: Presentation at 8:00 PM, followed by a discussion, dinner and some star-gazing.
Venue: Tunnel Top, Mini Matheran Resort
A large asteroid around 10 km wide likely struck the Earth around 65 million years ago in Mexico, causing earthquakes, tsunamis, and dust clouds that blocked the sun and led to the extinction of the dinosaurs. The moon releases gases like radon that cause hazy spots on its surface, and craters have been found near the areas where it releases gas. The "Man in the Moon" is actually just patterns that people imagine they see in the moon's craters and ancient lunar seas when viewing it with the naked eye.
This document provides an overview of an academic presentation on interstellar flight given by Kelvin F. Long, the executive director of the Institute for Interstellar Studies. The presentation discusses the history of interstellar studies and proposals, including projects by the British Interplanetary Society. It also examines the fundamental requirements and challenges of interstellar travel such as the large amounts of energy needed and long mission times. Finally, it introduces the Institute for Interstellar Studies and its mission to promote education and technologies that could enable interstellar spacecraft.
The document discusses the early expansion and formation of the universe according to the Big Bang theory and cosmic inflation theory. It describes how, nearly 14 billion years ago, the universe began as an infinitely small, dense, and hot ball that rapidly expanded and cooled over time, giving rise to space, matter, and energy. It also explains how cosmic inflation theory proposes that the early universe expanded exponentially faster than the speed of light for a fraction of a second, growing trillions of times larger and helping to explain the large-scale structure of the present-day universe.
This document presents a theory for the extinction of dinosaurs that involves significant changes to the Earth's structure and rotation. It suggests that around 65 million years ago, 3/4 of the Earth's continental crust broke off and coalesced into the Moon, causing a shift in the Earth's axis that introduced seasons. This event would have drastically altered gravity on Earth and made conditions inhospitable for the large dinosaur species. Evidence is presented that calculations of the mass of the Moon and missing continental crust support this theory. It aims to provide a more complex explanation than other popular theories like an asteroid impact.

How to Manage Reception Report in Odoo 17Celine George
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.

19. Reflections on a Mote of Dust
Carl Sagan (1934-1996)
We succeeded in taking that picture [from deep space], and, if you
look at it, you see a dot. That’s here. That’s home. That’s us. On it,
everyone you ever heard of, every human being who ever lived, lived
out their lives. The aggregate of all our joys and sufferings, thousands
of confident religions, ideologies and economic doctrines, every
hunter and forager, every hero and coward, every creator and
destroyer of civilizations, every king and peasant, every young couple
in love, every hopeful child, every mother and father, every inventor
and explorer, every teacher of morals, every corrupt politician, every
superstar, every supreme leader, every saint and sinner in the history
of our species, lived there on a mote of dust, suspended in a sunbeam.
The earth is a very small stage in a vast cosmic arena. Think of the
rivers of blood spilled by all those generals and emperors so that in
glory and in triumph they could become the momentary masters of a
fraction of a dot. Think of the endless cruelties visited by the
inhabitants of one corner of the dot on scarcely distinguishable
inhabitants of some other corner of the dot. How frequent their
misunderstandings, how eager they are to kill one another, how
fervent their hatreds. Our posturings, our imagined self-importance,
the delusion that we have some privileged position in the universe,
are challenged by this point of pale light.
Our planet is a lonely speck in the great enveloping cosmic dark. In
our obscurity — in all this vastness — there is no hint that help will
come from elsewhere to save us from ourselves. It is up to us. It’s been
said that astronomy is a humbling, and I might add, a character-
building experience. To my mind, there is perhaps no better
demonstration of the folly of human conceits than this distant image
“Plava tačka u beskraju” of our tiny world. To me, it underscores our responsibility to deal
Vojadžer 1; 6. jula 1990. godine. more kindly and compassionately with one another and to preserve
and cherish that pale blue dot, the only home we’ve ever known.

The Hubble Ultra Deep Field, or HUDF, is an image of a small region of space in the constellation Fornax, composited from Hubble Space Telescope data accumulated over a period from September 24, 2003 through January 16, 2004. It is the deepest image of the universe ever taken in visible light, looking back (to when the universe is thought to have been 800 million years old) approximately 13 billion years ago.[citation needed] The HUDF contains an estimated 10,000 galaxies[1]. The patch of sky in which the galaxies reside (just one-tenth the diameter of the full moon as viewed from Earth) was chosen because it had a low density of bright stars in the near-field. Although most of the targets visible in the Hubble image can also be seen at infrared wavelengths by ground-based telescopes, Hubble is the only instrument which can make observations of these distant targets at visible wavelengths. Located southwest of Orion in the Southern-Hemisphere constellation Fornax at right ascension 3h 32m 40.0s, declination -27° 47' 29" (J2000), the image covers 36.7 square arcminutes[2]. This is smaller than a 1 mm by 1 mm square of paper held 1 meter away, and equal to roughly one thirteen-millionth of the total area of the sky. The image is oriented such that the upper left corner points toward north (-46.4°) on the celestial sphere. The star near the center of the field is USNO-A2.0 0600-01400432 with apparent magnitude of 18.95. In total, the image required 800 exposures taken over the course of 400 Hubble orbits around Earth. The total amount of exposure time was 11.3 days for the ACS and 4.5 days for the NICMOS. According to the Big Bang theory, the universe has a finite age, so we might expect very distant (and hence very young) galaxies to look different from the typical older galaxies we see today. This is indeed seen in the HUDF, although some argue[citation needed] that the difference is partly a result of the unusual wavelength used for the HUDF (corresponding to ultraviolet light from the rest-frame of the most distant galaxies)[citation needed]. The Hubble Ultra Deep Field also shows more evidence for galaxy formation and merging than in local studies, as expected for the early universe[citation needed].
The Hubble eXtreme Deep Field ( XDF ) is an image of a small part of space in the center of the Hubble Ultra Deep Field within the constellation Fornax, showing the deepest optical view in space. [1][2] Released on September 25, 2012, the XDF image compiled 10 years of previous images and shows galaxies from 13.2 billion years ago. The exposure time was two million seconds, or approximately 23 days. The faintest galaxies are one ten-billionth the brightness of what the human eye can see. Many of the smaller galaxies are very young galaxies that eventually became the major galaxies, like the Milky Way and other galaxies in our galactic neighborhood. [2] The Hubble eXtreme Deep Field, or XDF , adds another 5,500 galaxies to those discovered in the Hubble Ultra-Deep Field. [3]
Female Queen Alexandra's Birdwings are larger than males with markedly rounder, broader wings. The female can reach a wingspan of 31cm (>14 inches), a body length of 8 cm (3.2 inches) and a body mass of up to 12 grams (0.42 oz), all enormous measurements for a butterfly. The female has brown wings with white markings and a cream-colored body with a small section of red fur on its thorax. Males are smaller than females with brown wings that have iridescent blue and green markings and a bright yellow abdomen. The wingspan of the males is approximately 20 cm, but more usually about 16 cm. A spectacular form of the male is form atavus, which has gold spots on the hind wings. It is restricted to the forests of Oro Province in eastern Papua New Guinea.
An optical fiber (or fibre) is a glass or plastic fiber that carries light along its length. Fiber optics is the overlap of applied science and engineering concerned with the design and application of optical fibers. Optical fibers are widely used in fiber-optic communication, which permits transmission over longer distances and at higher data rates than other forms of communications. Fibers are used instead of metal wires because signals travel along them with less loss, and they are immune to electromagnetic interference. Optical fibers are also used to form sensors, and in a variety of other applications. Light is kept in the "core" of the optical fiber by total internal reflection. This causes the fiber to act as a waveguide. Fibers which support many propagation paths or transverse modes are called multimode fibers (MMF). Fibers which support only a single mode are called singlemode fibers (SMF). Multimode fibers generally have a large-diameter core, and are used for short-distance communication links or for applications where high power must be transmitted. Singlemode fibers are used for most communication links longer than 200 meters. Joining lengths of optical fiber is more complex than joining electrical wire or cable. The ends of the fibers must be carefully cleaved, and then spliced together either mechanically or by fusing them together with an electric arc. Special connectors are used to make
