dramatic star formation regions
2014-08-20 06:03:47

redOrbit Staff & Wire Reports - Your Universe Online The Wide Field Imager at the ESO’s La Silla Observatory in Chile has captured new images of two dramatic regions of star formation in the southern Milky Way, one of which features a Wolf–Rayet multiple star system. [ Watch: Zooming In On Star Formation In The Southern Milky Way ] Wolf-Rayet stars, the ESO explains, are at an advanced stage of stellar evolution and begin with a mass approximately 20 times that of the sun....

New Evidence Explains How The 'Pillars Of Creation' Came Into Being
2014-06-27 06:48:02

Gerard LeBlond for redorbit.com - Your Universe Online [ Watch the Video: How The ‘Pillars of Creation’ Were Created ] The 'Pillars of Creation' is one of the most famous images observed by the Hubble Space Telescope. It shows cooler interstellar gases being eroded by intense radiation and wind from nearby massive stars. The image was photographed in 1995. Scott Balfour, an astronomer from Cardiff University produced a similar simulation and suggests that the stars that make the...

Supernova Progenitor Revealed
2014-05-22 06:28:27

redOrbit Staff & Wire Reports - Your Universe Online For the first time ever, astronomers have directly confirmed that a rare and extremely massive type of star known as a Wolf-Rayet star died in a violent explosion known as a Type IIb supernova, and their observations will help scientists better understand the life and death of the progenitor Wolf-Rayet. While our sun is 330,000 times more massive than Earth, comprises 99.86 percent of the total mass of the Solar System, and has a...

Snake Nebula
2014-02-26 12:49:25

[ Watch the Video: Birth Of A Star A Family Affair ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the Smithsonian's Submillimeter Array (SMA) telescope have imaged the most detailed look yet of stellar nurseries within the Snake nebula. The Snake nebula is about 11,700 light-years away from Earth towards the direction of the constellation Ophiuchus. The astronomers chose this nebula because it shows the potential to form many massive stars. "To learn how...

Sharpest Ever Image Of Prawn Nebula Unveiled
2013-09-18 10:42:57

[ Watch the Video: Zooming In On The Prawn Nebula ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the Very Large Telescope (VLT) at the European Southern Observatory's (ESO) Paranal Observatory in Chile have taken the sharpest image ever of the Prawn Nebula. The stellar nursery, formally known as IC 4628, sits 6,000 light-years from Earth in the constellation of Scorpius. The new image shows clumps of hot new-born stars nestled among the clouds making up the...

Hubble Views A Cosmic Caterpillar
2013-08-30 06:46:53

[ Watch The Video - Protostar IRAS 20324+4057 Zoom Sequence ] NASA/ESA Hubble Space Telescope This light-year-long knot of interstellar gas and dust resembles a caterpillar on its way to a feast. But the meat of the story is not only what this cosmic caterpillar eats for lunch, but also what's eating it. Harsh winds from extremely bright stars are blasting ultraviolet radiation at this "wanna-be" star and sculpting the gas and dust into its long shape. The culprits are 65 of the...

NASA’s Swift Maps Magellanic Clouds With Ultraviolet
2013-06-04 07:38:12

April Flowers for redOrbit.com — Your Universe Online Using NASA´s Swift satellite, astronomers from NASA and Pennsylvania State University have created the most detailed ultraviolet surveys to-date of the two closest major galaxies, the Large and Small Magellanic Clouds. "We took thousands of images and assembled them into seamless portraits of the main body of each galaxy, resulting in the highest-resolution surveys of the Magellanic Clouds at ultraviolet wavelengths,"...

Most Massive Binary Candidate Identified
2013-04-17 04:52:37

April Flowers for redOrbit.com - Your Universe Online A team of astronomers, led by Hugues Sana of the University of Amsterdam, has observed a binary star that potentially weighed 300 to 400 times the mass of our Sun at its birth. The present day combined mass of the two stars is between 200 and 300 times the solar mass, depending on its evolutionary stage. This makes it potentially the most massive binary star discovered to date. The findings of this study have been published in...

Older Stars Help Baby Stars Grow Up To Be Massive
2013-03-28 08:55:25

April Flowers for redOrbit.com - Your Universe Online Stars with ten times or more the mass of our Sun should not exist. They push away the gas they feed on as they grow, starving themselves for fuel. Astrophysicists have been struggling to understand how some stars are able to overcome this developmental hurdle. A group of researchers led by the University of Toronto suggests that baby stars might grow to have great mass if they are lucky enough to be born within a corral of older...

Solar Winds Examined By XMM-Newton
2013-02-05 18:03:01

Lee Rannals for redOrbit.com — Your Universe Online While solar wind is a common occurrence in our Solar System, a study of a new, more fierce wind has been completed using the European Space Agency's XMM-Newton space observatory. These massive stellar winds derive from rare, giant stars which burn their nuclear fuel more rapidly than stars like the Sun, and that live for millions of years before exploding into a supernova. Massive stars lose a significant fraction of their...

Star -- A star is a self-gravitating sphere of plasma in hydrostatic equilibrium that generates energy in its interior through the process of nuclear fusion. Energy from this process radiates into space as electromagnetic radiation and neutrinos. Star formation and evolution As learned by star formation astronomers, stars are born in molecular clouds, regions of higher density of matter, and form by gravitational instability inside those clouds. High mass stars illuminate powerfully...
