V838 Monocerotis
Space Phenomenon Imitates Art in Universe's Version of van Gogh Painting - V838 Monocerotis. Starry Night, Vincent van Gogh's famous painting, is renowned for its bold whorls of light sweeping across a raging night sky. Although this image of the heavens came only from the artist's restless imagination, a new picture from Hubble Space Telescope bears remarkable similarities to the van Gogh work, complete with never-seen spirals of dust swirling across trillions of miles of interstellar space.

Shuttle Challenger Disaster
When the Challenger disaster occurred, it exploded killing all aboard, it shocked the nation, started a NASA investigation, and led to many changes in the shuttle program. Here, we look back at the Challenger disaster to see what happened. Most of us remember where we were when we learned of the Challenger disaster.

Stonehenge Monument
No one is really sure who built Stonehenge or why it was built. Early theories were that it was constructed by the Druids or even the Romans, but those theories were disproved in the 20th century, when it was shown that construction began on Stonehenge over 2,000 years before Celts, and later Romans, had even arrived in the area. Most people believe that Neolithic peoples of the British Isles started building the Stonehenge monument around 5,000 years ago.

Top 10 Closest Stars
According to the About Astronomy and Space Online Dictionary, a star is a ball of mostly hydrogen and helium gas that shines extremely brightly. A star is so massive that its core is extremely dense and hot. At the high core temperatures of a star, atoms move so fast that they sometimes stick to other atoms when they collide with them, forming more massive atoms and releasing a great amount of energy. This process is known as nuclear fusion. Here are the Top 10 Closest Stars to our solar system.

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.

Abrasive Collision Black Eye
Hubble Space Telescope Image - An Abrasive Collision Gives One Galaxy a "Black Eye". A collision of two galaxies has left a merged star system with an unusual appearance as well as bizarre internal motions. Messier 64 (M64) has a spectacular dark band of absorbing dust in front of the galaxy's bright nucleus, giving rise to its nicknames of the "Black Eye" or "Evil Eye" galaxy.

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.

The Big Bang Theory
The Big Bang Theory is the dominant scientific theory about the origin of the universe. According to the big bang theory, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions. In 1927, the Belgian priest Georges Lemaître was the first to propose that the universe began with the explosion of a primeval atom.

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.

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.

Big Joe, the large rock just left of center is about 2 m (7 ft) wide. The top of the rock is covered with red soil. Those portions of the rock not covered are similar in color to basaltic rocks on Earth. This rock may be a fragment of a lava flow that was later ejected by an impact crater. The red color of the rocks and soil is due to an abundance of oxidized iron in the eroded material.

Asteroid Threat 2004 MN4
A recently rediscovered 400-meter Near-Earth Asteroid (NEA) is predicted to pass near the Earth on 13 April 2029. The flyby distance is uncertain and an Earth impact cannot yet be ruled out. The odds of impact, presently around 1 in 300, are unusual enough to merit special monitoring by astronomers, but should not be of public concern. In all likelihood, the possibility of impact will eventually be eliminated as the asteroid continues to be tracked by astronomers around the world.

Liquid Water on Mars
A series of troughs and layered mesas in the Gorgonum Chaos region of the Martian southern hemisphere appears in the chaotic terrain. Gullies proposed to have been formed by seeping ground water emanate from a specific layer near the tops of trough walls, particularly on south-facing slopes. Such a layer is called an aquifer, and this one appears to be present less than a few hundred meters (few hundred yards) beneath the surface in this region.

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.

Portrait of Pythagoras
While in Egypt, Pythagoras visited, or at least tried to visit, many of the temples and spoke with a large number of priests and scholars. There are some accounts that indicate he was denied access to all but a few temples. One, however, which he apprently entered was Diospolis, where he was accepted into the priesthood after completing the rites necessary for admission. While in Egypt, Pythagors continued his education, especially in mathematics and geometry.

View from Lander 2
This Viking Lander 2 site has more and larger blocks of stone than are seen at the Viking Lander 1 site. The stones are probably ejecta from impact craters near the Lander 2 site. Many of the rocks are angular and are thought to be only slightly altered by the wind and other forms of erosion. Drifts of sand and dust are smaller and less noticeable at the Lander 2 site. The overall red coloring of the Martian terrain is due to the presence of oxidized iron in the regolith.

Canyon and Volcanoes
This mosaic of Mars is similar to the view you would see from a spacecraft. The center of the scene shows the entire Valles Marineris canyon system, over 4000 km (2486 mi) long and up to 7 km (5 mi) deep. It extends from Noctis Labyrinthus, the arcuate system of graben on the west side, to the chaotic terrain on the east side. Many ancient river channels begin from the chaotic terrain and north-central canyons and run north. Three Tharsis volcanoes are visible to the west (dark red spots).

Mars Daily Global Image
Twelve orbits a day provided the Mars Global Surveyor MOC wide angle cameras a global snapshot of weather patterns across the planet in April, 1999. Here, bluish-white water ice clouds hang above the Tharsis volcanoes. This computer generated image was created by wrapping a global map onto a sphere. The center of this sphere is 15 degrees North latitude, 90 degrees West longitude. This perspective rotates the south pole (which has no data coverage in the original map) away from our field of view

Cerberus
The large dark area left of center is named Cerberus. The arcuate markings in the upper right are in the Amazonis plains and may be sand drifts. The Elysium volcano, a yellow area north of Cerberus, has several channels radiating from its flanks. The three bright spots, upper left, are volcanoes partially veiled by thin clouds.

Where is La Niña?
Since the weak El Niño event of winter of 2002, the equatorial Pacific has cooled and oceanographers have been on a La Niña "watch." Thus far, equatorial waters have seesawed between cooling and the present slight warming. Elsewhere, the northern and northeastern Pacific Ocean remains quite cool and sea levels are much lower than normal.

South Polar Projection of Eart
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.

Hubble Space Telescope
NASA named the world's first space-based optical telescope after American astronomer Edwin P. Hubble (1889–1953). Dr. Hubble confirmed an "expanding" universe, which provided the foundation for the Big Bang theory. Hubble's two mirrors were ground so that they do not deviate from a perfect curve by more than 1/800,000ths of an inch. If Hubble’s primary mirror were scaled up to the diameter of the Earth, the biggest bump would be only six inches tall.

The Earth and Moon
During its flight, the Galileo spacecraft returned images of the Earth and Moon. Separate images of the Earth and Moon were combined to generate this view. The Galileo spacecraft took the images in 1992 on its way to explore the Jupiter system in 1995-97. The image shows a partial view of the Earth centered on the Pacific Ocean about latitude 20 degrees south.

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.

The Sojourner rover and undeployed ramps onboard the Mars Pathfinder spacecraft can be seen in this image, by the Imager for Mars Pathfinder (IMP) taken on July 4, 1997. The microrover Sojourner is latched to the petal, and has not yet been deployed. The ramps are a pair of deployable metal reels that provide a track for the rover as it slowly rolls off the lander, over the spacecraft's deflated airbags, and onto the surface of Mars.
