Massive Star Formation Mystery Solved
2014-01-28 04:04:20

Enormous young stars, which have over 10 times the mass of the Sun, shine brilliantly in ultraviolet wavelengths, energizing the gas around them, and it has long been a mystery why this superheated gas doesn't explode outwards.

massive Star forming cluster discovered
2013-12-16 15:57:27

Astronomers have discovered a giant star-forming region located 36,000 light-years away from Earth shining 100 times brighter than the Orion nebula.

Tycho Supernova Mach 1000 Shock Wave
2013-11-26 15:49:52

New work on the Tycho supernova remnant has measured a reverse shock penetrating the remnant at more than 1,000 times the speed of sound in the gas.

Throes Of Stellar Birth Revealed As Never Before
2013-11-12 04:04:45

The bubbly birth of a bouncing baby star has been revealed by observations Spitzer and the newly completed Atacama Large Millimeter/submillimeter Array in Chile.

Coldest Known Object In Space Reveals Its Ghostly Figure
2013-10-25 06:25:12

The Boomerang Nebula, at a crisp one degree Kelvin (minus 458 degrees Fahrenheit), is the coldest known object in the Universe. In fact, the Boomerang Nebula is colder than the faint afterglow of the Big Bang, which is the natural background temperature of space.

Molecular Cloud Explains Star Formation
2013-10-22 12:16:19

The molecular clouds that float about the universe hold the ingredients for star formation, say researchers at University of California, San Diego.

ESO astronomers using the Very Large Telescope (VLT) reported today that they have captured a detailed image of the Toby Jug Nebula.

Astronomers Find Huge 'Hot Core' Enveloping Infant Star
2013-10-04 13:31:43

Astronomers have discovered an infant star while looking at an infrared dark cloud that is about ten times larger than those found around typical solar-mass baby stars.

Mapping Location Of Galactic Clouds
2013-09-11 14:31:55

Astronomers using the Mopra Telescope in Coonabarabran, Australia have begun mapping the location where stars are born.

Bizarre Alignment Observed In Butterfly-Shaped Nebulae
2013-09-04 08:57:07

Planetary nebulae occur in the final stages of a star's life when its outer layers begin to stretch out into the surrounding space. These nebulae can create beautiful objects in the night sky, with some stretching out into an hourglass or butterfly shape.

Supernova Remnant -- A supernova remnant (SNR) is made up of the materials left behind by the gigantic explosion of a star in a supernova. There are two possible routes to this end: either a massive star may cease to generate fusion energy in its core, and collapse inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches a critical mass and undergoes a similar collapse. In either case, the resulting supernova...

Star Formation -- Star formation is the process by which gas in molecular clouds gets transformed into stars. In the current paradigm of star formation, cores of molecular clouds (regions of specially high density) became gravitationally unstable, and start to concentrate. Part of the gravitational energy lost in the process is radiated in the infrared, another part increases the temperature of the core. The accretion of material happen partially though a circumstellar disc. When...

Reflection Nebula -- In astronomy, reflection nebulae are clouds of dust which are simply reflecting the light of a nearby star or stars. The nearby star or stars are not hot enough to cause ionization in the gas of the nebula like in emission nebulae but are bright enough to give sufficient scattering to make the dust visible. The distiction between these two types of nebulae was done by Hubble in 1922. They are usually blue because the scattering is more efficient for blue light...

Planetary Nebula -- A planetary nebula is an astronomical object that usually appears nebulous and disk-like in low-resolution observations. Because of this appearance, similar to the appearance of planets in early observations, the "planetary" adjective was attached and has since been retained for historical consistency. According to current observations and models, planetary nebulae in fact have little to do with planets. Instead, as a small star (less than a few times the mass...

Nebula -- in astronomy, observed manifestation of a collection of highly rarefied gas and dust in interstellar space. Prior to the 1960s this term was also applied to bodies later discovered to be galaxies, e.g., the so-called Great Nebula in the constellation Andromeda. In 1864, William Huggins confirmed William Herschel's conclusion that nebulae are not swarms of stars by determining that the spectra of nebulae are made of bright lines characteristic of radiating gases. Diffuse...
