Star Cluster Study Inspires New Ideas On How Sun-Like Stars Form
2014-05-08 10:15:43

Brett Smith for redOrbit.com - Your Universe Online The prevailing theory on star cluster formation states that gravity causes a giant cloud of gas and dust to condense to concentrations that trigger the ignition of stars at the center of the cloud. However, according to a new study based on data from NASA's Chandra X-ray Observatory and infrared telescopes, some of the oldest stars in known clusters sit on the exterior of their groups. The study researchers focused on two clusters...

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...

Birth Of A Star In Cepheus
2013-04-02 13:51:41

National Optical Astronomy Observatory Watching starbirth isn´t easy: tens of millions of years are needed to form a star like our Sun. Much like archeologists who reconstruct ancient cities from shards of debris strewn over time, astronomers must reconstruct the birth process of stars indirectly, by observing stars in different stages of the process and inferring the changes that take place. Studies show that half of the common stars, including our Sun, formed in massive clusters,...

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...

Flame On! New Image Shows Flame Nebula In Its Full Glory
2012-07-03 12:28:23

Lee Rannals for redOrbit.com - Your Universe Online The cosmos is full of outstanding imagery, and a new image from NASA's Wide-field Infrared Survey Explorer, or WISE, has shot back another outstanding image back to Earth. The latest image, released on Monday, shows a Flame nebula located in the Orion complex, lighting up a cavern of dust. The Nebula is sitting on the eastern hip of Orion the Hunter, which is a constellation that can be seen with the naked eye in the northern...

The Orion Nebula reveals many of its hidden secrets in a dramatic image taken by ESO's new VISTA survey telescope. The telescope's huge field of view can show the full splendor of the whole nebula and VISTA's infrared vision also allows it to peer deeply into dusty regions that are normally hidden and expose the curious behavior of the very active young stars buried there. VISTA "” the Visible and Infrared Survey Telescope for Astronomy "” is the latest addition to ESO's Paranal...

A collection of 30 never-before-released images of embryonic planetary systems in the Orion Nebula are the highlight of the longest single Hubble Space Telescope project ever dedicated to the topic of star and planet formation. Also known as proplyds, or protoplanetary discs, these modest blobs surrounding baby stars are shedding light on the mechanism behind planet formation. Only the NASA/ESA Hubble Space Telescope, with its high resolution and sensitivity, can take such detailed pictures...

Astronomers have completed the most comprehensive census of the star formation surrounding the Orion Nebula. Using the United Kingdom Infrared Telescope (UKIRT) in Hawaii, the IRAM Millimeter-wave Telescope in Spain, and the orbiting Spitzer Space Telescope, astronomers have uncovered a much busier scene than previously considered in and around Orion, some 1300 light years away from Earth. They found that a stellar nursery exists behind the constellation, and can be vaguely seen through the...

Orion Nebula -- Discovered 1610 by Nicholas-Claude Fabri de Peiresc. Located at a distance of about 1,600 (or perhaps 1,500) light years, the Orion Nebula is the brightest diffuse nebula in the sky, visible to the naked eye, and rewarding in telescopes of every size, from the smallest glasses to the greatest Earth-bound observatories and the Hubble Space Telescope. It is the main part of a much larger cloud of gas and dust which extends over 10 degrees well over half the constellation...

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...
