Brightest Stars
Stars are massive shining spheres of hot gas, the closest of which is our Sun. Stars are primarily made of hydrogen, smaller amounts of helium, and trace amounts of other elements. Even the most abundant of the other elements present in stars (oxygen, carbon, neon, and nitrogen) are only present in very small quantities. Those stars which you see with your naked eye in the night sky all belong to the Milky Way Galaxy, the huge system of stars that contains our solar system.

Aristotle Biography
Aristotle was born around 384 BC in Stagirus, Greece. Around the age of 17, Aristotle became a student at Plato's Academy in Athens. Aristotle was so impressive as a student that he soon became a teacher, himself, remaining at the academy for 20 years. In 335 BC Aristotle traveled to Athens with his circle of assistants to staff his new school, the Lyceum. Two areas which he advanced, which are of particular interest to readers of this site were physics and astronomy. He died at the age of 62.

Pythagoras of Samos Biography
Pythagoras, the son of Mnesarchus and Pythais, was born on the island of Samos, off the coast of Asia Minor (what is now mostly Turkey), about 569 BC. Besides his contributions to mathematics, Pythagoras was essential to the early field of astronomy. As Plato later would believe, Pythagoras felt the sphere was the perfect shape. This may have lead to his assertion that the Earth was a sphere. He realized the orbit of the Moon was inclined to the equator of the Earth.

Pluto Picture - Pluto in True Color
Pluto is mostly brown. This picture captures the true colors of Pluto as well as the highest surface resolution so far recovered. No spacecraft has yet visited this most distant planet in our Solar System. The above map was created by tracking brightness changes from Earth of Pluto during times when it was being partially eclipsed by its moon Charon. The map therefore shows the hemisphere of Pluto that faces Charon.

Telescopes In A Nutshell
While many people are under the impression that Galileo Galilei invented the telescope, that's not true at all. We're not exactly sure who the true inventor was, there was even some controversy at the time. However, today, the honor is usually ascribed to the man who first requested a patent for the device from the government of the Netherlands for a patent in 1608, Hans Lippershey. Telescopes come in three basic designs; Refractor, Reflector, and Catadioptric.

Halley's Comet
Using Newton's new Laws of motion, the astronomer, Edmond Halley, made a prediction in 1705. He stated that a comet which had appeared in 1531, 1607 and 1682 would reappear in 1758. Although he was proven to be correct, Halley did not live to see it. However, the comet was later named in his honor. During the 20th century, Halley's Comet appeared in 1910 and 1986. During that most recent visit, five spacecraft from the USSR, Japan, and the European Community journeyed to Comet Halley.

The Evolution of the SpaceSuit
Ever since Alan Shepard's history making flight in 1961, NASA astronauts have relied on spacesuits to help them work and keep them safe. From the shiny silver of the Mercury suit to the orange "pumpkin suits" of shuttle crew, the suits have served as personal spacecraft, protecting explorers during launch and entry, while working on the International Space Station, or walking on the moon.

Meteoroids
Shooting stars or meteors are bits of material falling through Earth's atmosphere; they are heated to incandescence by the friction of the air. The bright trails as they are coming through the Earth's atmosphere are termed meteors, and these chunks as they are hurtling through space are called meteoroids. Large pieces that do not vaporize completely and reach the surface of the Earth are termed meteorites.

Messenger Spacecraft Images of Mercury - Mercury - - In Color!!
One week ago, the MESSENGER spacecraft transmitted to Earth the first high-resolution image of Mercury by a spacecraft in over 30 years, since the three Mercury flybys of Mariner 10 in 1974 and 1975. MESSENGER's Wide Angle Camera (WAC), part of the Mercury Dual Imaging System (MDIS), is equipped with 11 narrow-band color filters, in contrast to the two visible-light filters and one ultraviolet filter that were on Mariner 10's vidicon camera.

Blue Moon
Blue Moon. Once in a blue moon. You have probably heard this expression before. It usually means not very often. But, is there really such a thing as a blue moons? Well, yes, but it's probably not what you may think, and a blue moon is definitely not what it used to be.

15 Minute Intro to Night Sky
People have been looking up at the night sky for as long as there have been people. Ancient people had many theories about what those strange lights in the sky were. Today, we know they are stars, like our own Sun, but to the early humans they were magical. Have you ever looked at the clouds and seen pictures? Well, as those ancient humans looked at the stars, they began to see patterns too. Some of these pictures they saw, reminded them of stories they had heard.

Earth Pictures - Global View of Earth in the Near-Infrared
This near-infrared photograph of the Earth was taken by the Galileo spacecraft at 6:07 a.m. PST on Dec. 11, 1990, at a range of about 1.32 million miles. The camera used light with a wavelength of 1 micron, which easily penetrates atmospheric hazes and enhances the brightness of land surfaces. South America is prominent near the center; at the top, the East Coast of the United States, including Florida, is visible. The West Coast of Africa is visible on the horizon at right.

Earth Pictures - Earth and Moon as viewed from Mars
This is the first image of Earth ever taken from another planet that actually shows our home as a planetary disk. Because Earth and the Moon are closer to the Sun than Mars, they exhibit phases, just as the Moon, Venus, and Mercury do when viewed from Earth. As seen from Mars by MGS on 8 May 2003 at 13:00 GMT (6:00 AM PDT), Earth and the Moon appeared in the evening sky.

Earth Pictures - Earth From Mars
This is the first image ever taken of Earth from the surface of a planet beyond the Moon. It was taken by the Mars Exploration Rover Spirit one hour before sunrise on the 63rd Martian day, or sol, of its mission. The image is a mosaic of images taken by the rover's navigation camera showing a broad view of the sky, and an image taken by the rover's panoramic camera of Earth. The contrast in the panoramic camera image was increased two times to make Earth easier to see.

Image of the Week for October 26, 2007 Quintuplet Cluster
Penetrating 25,000 light-years of obscuring dust and myriad stars, the Hubble Space Telescope has provided the clearest view yet of one of the largest young clusters of stars inside our Milky Way galaxy, located less than 100 light-years from the very center of the Galaxy. Having the equivalent mass greater than 10,000 stars like our sun, the monster cluster is ten times larger than typical young star clusters scattered throughout our Milky Way.

Occasionally, a planet in our Solar System will pass in front of a bright star. Since stars and planets take up so little space on the sky, such events are quite rare. Two months ago, however, Pluto and its large moon Charon passed in front of a comparatively bright triple star system known as P126. By noting how P126 A dimmed, the event was useful for studying Pluto's relatively unknown atmosphere.

Asteroid Information
Asteroids are rocky fragments left over from formation of the solar system about 4.6 billion years ago. Most of these fragments of ancient space rubble can be found orbiting the Sun in a belt between Mars & Jupiter. This region in our solar system, called the Asteroid Belt or Main Belt, probably contains millions of asteroids ranging widely in size from Ceres, which at 940 km in diameter is about one-quarter the diameter of our Moon, to bodies that are less than 1 km across.

Space Disasters and Tragedies
Space is a dangerous place. In all of human endeavor, there is danger. It is not possible to completely avoid risk. Even if you choose to hide in your home, some danger still exists. To live is to risk, but there are those, particularly those who work for the betterment of mankind, who risk more than others. From the fire and police officials who entered two buildings struck by terrorists in New York to the seven members of the space shuttle Columbia crew, exploring the final frontier.

10 Things About Earth
Earth, our home planet, is the only planet whose name is not derived from Greek/Roman mythology. In Roman Mythology, the goddess of the Earth was Tellus - the fertile soil, while the Greek goddes was Gaia, terra mater - Mother Earth. The name we use today, Earth, comes from Old English and Germanic.

Timeline of the Universe
Scientists believe that the universe was created about 15 billion years ago in a single violent event known as the Big Bang. All the space, time, energy, and matter that constitute today's universe originated in the Big Bang. The early universe was extremely small, dense, and hot. For the first fraction of a second, only energy existed.

Hans Lippershey Biography
Hans Lippershey was born in Wesel (western Germany) around the year 1570. Little is known about his early life, but he eventually moved to Middelburg, the capital of Zeeland, the southwesternmost province of the Netherlands. Hans Lippershey was probably not the first person to experiment with combining lenses to create crude telescopes and binoculars. While others later claimed to have invented the device, it was Lippershey who applied to the government of the Ntherlands for a patent in 1608.

What Is The Solar System?
Solar means dealing with the sun, Sol. Our sun is just a star, the closest one to Planet Earth. The Solar System is everything that centers around the sun. That includes 8 planets as well as some smaller objects such as asteroids, comets and meteoroids. Previously, we had considered one of those smaller objects to be a ninth planet, but last year, the International Astronomical Union decided that Pluto is a Dwarf Planet.

New Asteroid Threat to Earth
New Asteroid Threat to Earth - Impact Potential in 2014. Although scientists have basically cleared us from any danger from asteroid 2002 NT7, which originally had been reported as an impact hazard for the year 2019, a newer space rock has been spotted. Has been called "an event meriting careful monitoring" by astronomers. If an impact does occur, it could be on March 21, 2014.

Aristotle Pictures - Aristotle from The School of Athens
A detail from the fresco The School of Athens by Raphael. The events leading to Aristotles departure from the academy are a bit cloudy. Some say that after Plato died in 347 BC, Speusippus assumed the leadership of the Academy. Perhaps Aristotle quit because he disagreed with Speusippus's views, or had hoped to be named Plato's successor, himself. Another theory deals with Aristotle's old friend, Philip of Macedonia.

Visible in the lower right corner of the image is the lander's footpad. The shroud that protected the soil collector head during the lander's descent lies a short distance from the footpad. The rounded rock in the center foreground is about 20 cm (8 in) wide. The angular rock to the left and further back is about 1.5 m (5 ft) across. Notice the two trenches dug in the regolith by the sampler arm.

Earth Pictures - South Polar Projection of Earth
This view of the Earth shows a wonderfully unique but physically impossible view of the southern hemisphere and Antarctica. While a spacecraft could find itself directly over the Earth's pole, roughly half of the image should be in darkness! This view was created by mosaicing together several images taken by Galileo over a 24 hour period and projecting them as they would be seen from above the pole.

Pluto Picture - Hubble Portrait of the "Double Planet" Pluto & Charon
This is the clearest view yet of the distant planet Pluto and its moon, Charon, as revealed by NASA's Hubble Space Telescope (HST). The image was taken by the European Space Agency's Faint Object Camera on February 21, 1994 when the planet was 2.6 billion miles (4.4 billion kilometers) from Earth; or nearly 30 times the separation between Earth and the sun. Hubble's corrected optics show the two objects as clearly separate and sharp disks.

Venus in Color
The bluish hue of Venus is an effect of the colorization technique used to enhance subtle contrasts in cloud patterns and indicates that this image was taken through a violet filter. Features in the sulfuric acid clouds near the top of the planet's atmosphere are most prominent in violet and ultraviolet light. This image shows the east to west cloud banding and the brighter polar hoods . The features are embedded in winds that flow from east to west at about 370 kph (230 mph).

Proxima Centauri Information
The closest star to our our own solar system will not always be closest, but it will be a long time before that happens. Proxima Centauri is the third star in the Alpha Centauri star system Also known as Alpha Centauri C, it circles its two companions at about 930 billion miles. This orbit takes millions of years, but will eventually carry Proxima far enough that its companions,collectively known as Rigel Kentaurus, will be closer. It is a red dwarf star, much smaller and cooler than the Sun.
