Protostars In Orion Nebula Doomed By Larger Stars
2014-03-11 06:11:18

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found that some protostars in the Orion Nebula are doomed from the beginning. The Orion Nebula has hundreds of young stars, or protostars, and even some “proplyds,” which are stars that are even younger than protostars. Astronomers have discovered that some of these young stars will have their planet-forming dust and gas blasted away from another star when...

[ Watch The Video: Zooming in on the Bright Star Cluster Messier 7 ] ESO Messier 7, also known as NGC 6475, is a brilliant cluster of about 100 stars located some 800 light-years from Earth. In this new picture from the Wide Field Imager on the MPG/ESO 2.2-meter telescope it stands out against a very rich background of hundreds of thousands of fainter stars, in the direction of the center of the Milky Way. At about 200 million years old, Messier 7 is a typical middle-aged open...

Ghostly Trio Imaged Using NASA's Spitzer Space Telescope
2013-10-29 10:12:36

NASA's Jet Propulsion Laboratory In the spirit of Halloween, scientists are releasing a trio of stellar ghosts caught in infrared light by NASA's Spitzer Space Telescope. All three spooky structures, called planetary nebulas, are in fact material ejected from dying stars. As death beckoned, the stars' wispy bits and pieces were blown into outer space. "Some might call the images haunting," said Joseph Hora of the Harvard-Smithsonian Center for Astrophysics, Cambridge, Mass., principal...

Cats Paw Nebula Baby Boom
2013-06-06 13:58:02

Lee Rannals for redOrbit.com - Your Universe Online Astronomers presented research on Wednesday at the American Astronomical Society (AAS) about how the Cat's Paw Nebula is experiencing a "baby boom." The team said the nebula, or NGC 6334, is forming stars at a more rapid pace than the Orion Nebula, which is one of the closest stellar nurseries to Earth. "It might resemble a 'mini-starburst,' similar to a scaled-down version of the spectacular bursts sometimes seen in other...

Hubble Provides Most Detailed Image Of Ring Nebula To Date
2013-05-23 12:48:25

[WATCH VIDEOS: Flying Around The Ring Nebula | Secrets Of The Ring Nebula] Lee Rannals for redOrbit.com — Your Universe Online The Hubble Space Telescope has provided one of the most detailed images of the Ring Nebula so far, allowing scientists to construct a model of the nebula in 3D. The Ring Nebula, or Messier 57, is an archetypal planetary nebula relatively close to Earth at 2,000 light-years away. NASA said Messier 57 is the glowing remains of a Sun-like star. The...

Astronomers Focus In On Recently Formed Stars In The Southern Constellation Of Vela
2013-03-27 06:18:20

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have unveiled a new image of recently formed bright blue stars in the cluster NGC 2547. Astronomers using the Wide Field Imager on the MPG/ESO 2.2-meter telescope at the European Space Observatory's (ESO) La Silla Observatory in Chile took images of the stars while they were focusing in on the southern constellation of Vela (The Sail). Despite the universe being roughly 13.8 billion years old, new stars and objects are...

WISE Captures The Heat From Orion's Sword
2013-02-06 09:58:22

NASA's Jet Propulsion Laboratory The tangle of clouds and stars that lie in Orion's sword is showcased in a new, expansive view from NASA's Wide-field Infrared Survey Explorer, or WISE. Orion, the famous hunter, is visible in evening skies throughout the world from about December through April. The constellation appears tranquil and still to the naked eye, but lying in its sword, at what appears to be a slightly fuzzy star, is a turbulent cauldron of stellar birth. WISE scanned the...

Orion Nebula Lives Behind Cluster Of Older Stars
2012-11-14 06:26:22

April Flowers for redOrbit.com - Your Universe Online A little over 400 years ago, French astronomer Nicolas-Claude Fabri de Peiresc first discovered the "fog" that is the Orion nebula. Located a mere 1,500 light years from our solar system, the Orion nebula is one of the great wonders of the night sky whose discovery is intimately associated with the early development of telescopes. Scientists have only realized the importance of the nebula in the last 60 years: the Orion nebula, like...

For decades, astronomers have been blind to what our galaxy, the Milky Way, really looks like. After all, we sit in the midst of it and can't step outside for a bird's eye view.Now, new images from NASA's Spitzer Space Telescope are shedding light on the true structure of the Milky Way, revealing that it has just two major arms of stars instead of the four it was previously thought to possess."Spitzer has provided us with a starting point for rethinking the structure of the Milky Way," said...

NASA spacecraft are monitoring an interstellar wind coming from the constellation Ophiuchus. Science@NASA -- Every year in early December, something happens that can throw your horoscope out of whack. The sun enters Ophiuchus, the little-known 13th house of the zodiac. You've probably heard of Capricorn, Aquarius, Pisces, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio and Sagittarius. The sun passes through these constellations, one by one, throughout the year. They're the ancient...

Trifid Nebula -- Discovered by Charles Messier in 1764. Charles Messier discovered this object on June 5, 1764, and described it as a cluster of stars of 8th to 9th magnitude, enveloped in nebulosity. The Trifid Nebula M20 is famous for its three-lobed appearance. This may have caused William Herschel, who normally carefully avoided to number Messier's objects in his catalog, to assign four different numbers to parts of this nebula: H IV.41 (cataloged May 26, 1786) and H V.10, H V.11,...

Owl Nebula -- Dicovered by Pierre Mchain in 1781. The Owl Nebula M97 is one of the fainter objects in Messier's catalog, discovered by Pierre Mchain on February 16, 1781. In his description of this object, Charles Messier also mentions two other nebulous objects that he (and Mchain) have seen at about the same time, but which he had not added in his printed catalog version of 1781 (in the Connaissance des Temps for 1784). As the description is obvious and he added positions by...

Cone Nebula -- The Cone Nebula is a famous nebula in the Orion Arm surrounding the NGC 2264 star cluster. The 'cone' is a triangular dark nebula near the bottom of the nebula. The bright star at the centre of this picture is 15 Monocerotis (or 'S Monocerotis') - it is a quadruple star system consisting of four brilliant blue-white stars (classes O7, B7, B8 and A6) and it is partly responsible for causing the nebula to glow. The distance to the Cone Nebula is well-known, because it has...
