• The large majestic Lagoon Nebula is home for many young stars and hot gas. Spanning 100 light years across while lying only about 5000 light years distant, the Lagoon Nebulae is so big and bright that it can be seen without a telescope toward the constellation of Sagittarius. Many bright stars are visible from >NGC 6530, an open cluster that

  • After undocking, the space shuttle Discovery crew got a memorable view of the developing International Space Station (ISS). Pictured orbiting high above Earth last month, numerous solar panels, trusses, and science modules of the ISS were visible. The Discovery crew brought mission specialist Nicole Stott to the ISS, and returned astronaut Timothy Kopra to Earth. Among the many mission and

  • Are square A and B the same color? They are. Are too. To verify this, click here to see them connected. The above illusion, called the same color illusion, illustrates that purely human observations in science may be ambiguous or inaccurate. Even such a seemingly direct perception as relative color. Similar illusions exist on the sky, such as the size

  • Scheduled to illuminate the landscape throughout the night tomorrow, October’s bright Full Moon will also be called the Harvest Moon. Traditionally, the Harvest Moon is the Full Moon closest to the autumnal equinox. But in this vacation snapshot, the Full Moon could be called the “Old Faith-Full Moon”. Taken on September 4, the picture combines the regularly occurring lunar phase

  • These colorful panels both feature a familiar northern hemisphere astronomical sight: the stellar nursery known as the Great Orion Nebula. They also offer an intriguing and unfamiliar detail of the nebula rich skyscape — a passing comet. Recorded this weekend with a remotely operated telescope in New Mexico, the right hand image was taken on September 26 and the left

  • This cosmic pillar of gas and dust is nearly 2 light-years wide. The structure lies within one of our galaxy’s largest star forming regions, the Carina Nebula, shining in southern skies at a distance of about 7,500 light-years. The pillar’s convoluted outlines are shaped by the winds and radiation of Carina’s young, hot, massive stars. But the interior of the

  • How would Saturn look if its ring plane pointed right at the Sun? Before last month, nobody knew. Every 15 years, as seen from Earth, Saturn’s rings point toward the Earth and appear to disappear. The disappearing rings are no longer a mystery — Saturn’s rings are known to be so thin and the Earth is so near the Sun

  • The constellation of Orion holds much more than three stars in a row. A deep exposure shows everything from dark nebula to star clusters, all imbedded in an extended patch of gaseous wisps in the greater Orion Molecular Cloud Complex. The brightest three stars on the far left are indeed the famous three stars that make up the belt of

  • Water has been discovered on the surface of the Moon. No lakes have been found, but rather NASA’s Moon Mineralogy Mapper aboard India’s new Chandrayaan-1 lunar orbiter radios back that parts of the Moon’s surface absorb a very specific color of light identified previously only with water. Currently, scientists are trying to fit this with other facts about the Moon
