Detailed analysis of different stellar populations in the disk of Andromeda suggests the galaxy may have had a far more violent history of mergers with smaller galaxies than the Milky Way, researchers from the University of California, Santa Cruz report in a new study.

Something seems to be missing in a new image captured by the European Southern Observatory (ESO) this week – there’s a large patch of darkness where there should be stars.

Stars reveal how old they are through their spin rate, and just as we humans slow down as we grow older, so do the massive, luminous balls of plasma found in space, according to research published Monday in the journal Nature.

While it may not have an out-of-this-world taste, the toothpaste that helps keep our molars and bicuspids healthy does contain a substance that was likely originally formed billions of years in long-dead stars similar to our sun, according to a new study.

Brett Smith for redOrbit.com - Your Universe Online Astrophysicists have suspected that desolate “red and dead” galaxies are only formed by powerful supermassive black holes at the center of these galaxies stripping away all of the essential star-forming gas from a stellar nursery. However, a new study in The Astrophysical Journal has revealed that less powerful black holes are capable of creating dead galaxies full of red giant stars by generating a “perfect storm” of...

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...

UV Astronomy -- UV astronomy is the branch of astronomy and astrophysics which deals with objects visible in ultraviolet (UV) radiation. UV radiation ranges approximatively from 10nm (extreme UV) to 380nm (near UV). Ultraviolet line spectrum measurements are used to discern the chemical composition, densities, and temperatures of interstellar medium, and the temperature and composition of hot young stars. UV observations can also provide essential information about the evolution of...

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...

X-ray Burster -- X-ray bursters are a class of binary stars which are luminous in X-rays. They contain a neutron star and a low-mass companion star. The companion fills its Roche lobe and therefore the neutron star is accreting matter from it. The inflowing gas forms an accretion disk around the neutron star. Sometimes X-ray bursters show a sudden increase in their X-ray luminosity, called X-ray burst. All properties of the X-ray bursts can be explained assuming that they result from...

Variable Star -- Most stars are of nearly constant luminosity. Our own Sun is a good example which goes through practically no measurable variation in brightness. There are, however, stars which do vary in brightness, called variable stars. They fall into two main groups: Intrinsic variables These are stars which have intrinsic variations in brightness, that is the star itself gets brighter and dimmer. There are many types of intrinsic variables, the main types being: -- Mira...
