Latest Stellar astronomy Stories
A group of international scientists have observed as the largest known star in the Universe tore itself apart.
PGC 6240 is an elliptical galaxy that resembles a pale rose in the sky, with hazy shells of stars encircling a very bright center.
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.
In an attempt to better understand unusual star formation, researchers are examining a dense gas cloud near the galactic center, one that they describe as a particularly “inhospitable place."
This particular object, located some 23,000 light-years away in the constellation Triangulum Australe, is in the early stages of its death cycle.
New observations of magnetic jets may shed some light on how stars transition into planetary nebulae.
Researchers at the Max Planck Institute have now created the most detailed 3D model of the inner structure of the Milky Way ever.
Astronomers using the Mopra Telescope in Coonabarabran, Australia have begun mapping the location where stars are born.
A worldwide network of radio telescopes has allowed astronomers to find strong evidence that a powerful jet of material is blowing massive amounts of gas out of the host galaxy.
This light-year-long knot of interstellar gas and dust resembles a caterpillar on its way to a feast.
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...
