ESA Confirms Inside Out Model Milky Way
2014-01-20 11:40:56

New research from the Gaia-ESO project confirmed previous theories on the inside-out development of the Milky Way, which holds that the inner regions of the galaxy’s disc were the first to form.

Located about 440 light-years from Earth is a strange object that has properties of both a star and a planet.

Storms As Big As Jupiter's 'Great Red Spot' Found On Brown Dwarfs

Most brown dwarfs may contain storms as big as Jupiter’s “Great Red Spot,” according to findings presented at the American Astronomical Society in Washington.

Discovery Helps Explain Binary Systems

Astronomers using the Very Large Array (VLA) have made a discovery that helps explain how double-star systems form.

Astronomers Search For Cause Of Massive Star Formation
2013-12-21 04:25:12

In an attempt to determine why massive stars – those with at least eight times the mass of our Sun – grow so much larger than most other stars in our galaxy, astronomers used the ALMA telescope to examine the cores of Infrared Dark Clouds roughly 10,000 light-years away.

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

Where Brown Dwarfs End And Stars Begin
2013-12-15 04:37:49

While astronomers have previously calculated the threshold at which an object will become a star instead of a brown dwarf, observational evidence has been elusive.

Explosive Milky Way Protostar Reveals Details About Star Formation
2013-12-04 14:04:38

Using the Atacama Large Millimeter Array telescope in northern Chile, scientists have identified a very young star in our galaxy which had such an explosive birth, it used to be about 100 times brighter than it is now.

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

Hertzsprung-Russell Diagram -- In stellar astronomy, the Hertzsprung-Russell diagram (H-R diagram) shows the relation between the absolute magnitude and the spectral types of stars. It was invented around 1910 by Ejnar Hertzsprung and Henry Norris Russell. There are two equivalent forms. One is the observer's form which plots the color of the star on one axis and the absolute magnitude on the other axis. The theoretician's form plots the temperature of the star on one axis and the...

Stellar Evolution -- Stellar evolution is the process of formation, life, and death of stars. It is one of the major topics of cosmogony. Star Birth and Life A star starts out as an enormous cloud of gas and dust many light-years across. Star formation begins when the cloud begins to condense under its own gravity. The processes that initiate this contraction are not fully understood. The cloud fragments fuse into stellar mass clouds known as protostars. Protostars do not emit...

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...

Star Designation -- The International Astronomical Union (IAU) is the internationally recognised authority for assigning designations to stars (and other celestial bodies). Many of the star names in use today were inherited from the time before the IAU existed. Other names, mainly for variable stars (including novae and supernovae), are being added all the time. Most stars, however, have no name and are referred to, if at all, by means of catalogue numbers. This article briefly...
