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

April Flowers for redOrbit.com - Your Universe Online The Boomerang Nebula, at a crisp one degree Kelvin (-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. To learn more about this intriguing object, a team of astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) telescope to investigate its frigid properties and...

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

Brett Smith for redOrbit.com - Your Universe Online The molecular clouds that float about the universe hold the ingredients for star formation, and a new study from researchers at University of California, San Diego has confirmed the mechanics behind three observed relationships describing the internal forces acting within these clouds, called Larson’s Laws. First postulated in 1981 by Richard Larson, a professor of astronomy at Yale, Larson's Laws detail the observation-based...

[ Watch The Video: Zooming In On To The Toby Jug Nebula ] Lee Rannals for redOrbit.com - Your Universe Online ESO astronomers using the European Souther Observatory's (ESO) Very Large Telescope (VLT) reported today that they have captured a detailed image of the Toby Jug Nebula. The nebula featured in the latest ESO image is a cloud of gas and dust surrounding a red giant star. The image shows the characteristic arc structure of the nebula resembles a jug with a handle. The Toby Jug...

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

Lee Rannals for redOrbit.com - Your Universe Online 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. A team using the ALMA Observatory was looking at infrared dark cloud G34.43+00.24 MM3 when it discovered the baby star. Hot molecular clouds around new-born stars are known as "Hot Cores" and have temperatures that are 100 degrees hotter than normal molecular clouds....

Mapping Location Of Galactic Clouds

[ Watch the Video: Mapping Our Milky Way Galaxy ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the 22-meter Mopra Telescope in Coonabarabran, Australia have begun mapping the location where stars are born. In January, wildfires destroyed the telescope's adjoining workshop, office and accommodations, but Mopra's control room was spared because it was encased in brick. The team from the University of New South Wales (UNSW) wrote in the journal Publications of...

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

Lee Rannals for redOrbit.com - Your Universe Online A new study by astronomers from the University of Manchester shows how planetary nebulae line up in the sky in the same way. A planetary nebula occurs in the final stages of a star's life when its outer layers begin to stretch out into the surrounding space. Such nebulae can create beautiful objects in the night sky, with some stretching out into an hourglass or butterfly shape. The latest research, published in the Monthly Notices of...

ALMA Pics Dramatic Star Birth

Lee Rannals for redOrbit.com - Your Universe Online Astronomers say they have obtained a close-up view of material streaming away from a newborn star. Using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope, a team of scientists was able to discover the jets coming off an object called Herbig-Haro 46/47 are even more energetic than previously believed. The new images also reveal a previously unknown jet pointing in an entirely different direction. The new images reveal...

How Fast Does A Supernova Shockwave Travel? A Japan Team May Have The Answer
2013-08-13 14:51:55

Brett Smith for redOrbit.com - Your Universe Online Some of the most spectacular explosions this side of the Big Bang, supernovae generate unthinkable amounts of force and energy and new research from Keio University in Japan has measured the expansion velocity of a supernova shockwave for the first time. The shockwave measured by the research team was from the supernova remnant W44, which is located approximately 10,000 light years from Earth. Quantifying the expansion and kinetic...

Life Of Eskimo Nebula Coming To A Beautiful End
2013-07-13 08:19:42

April Flowers for redOrbit.com - Your Universe Online At the end of their lives, stars like our Sun become remarkably photogenic. For example, NGC 2392, located approximately 4,200 light years from Earth, is giving astronomers a beautiful display as it nears the end of its existence. NGC 2392, referred to as a "planetary nebula," has been nicknamed the Eskimo Nebula; however "planetary nebula" is misleading because nebulae have nothing to do with planets. Rather, the term is an...

ALMA Scan Reveals Embryonic Star Formation
2013-07-10 05:07:12

[ Watch the Video: Zooming in on the Birth of a Monster Star ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers used ESO's Atacama Large Millimeter/submillimeter array (ALMA) to gain one of the best views yet of a star in the process of forming. The embryonic monster star sits inside Spitzer Dark Cloud (SDC) 335.579-0.292 right now, which contains over 500 times the mass of the Sun. Astronomers say the cloud will be giving birth to a very brilliant star with up to...

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...
