Nearby Flare Star Gives Burst Of Light
2013-06-14 12:17:36

Within a span of three minutes, a star in the Usra Major constellation less than 16 light-years from Earth gave off a massive flare, making the object 15 times brighter than normal, according to a new report in the journal Astrophysics.

More Galactic Gas In Milky Way Than We Thought
2013-06-11 14:31:02

The building blocks of stars, molecular gases and clouds, are strewn across the Milky Way, and a new study has found that scientists have been underestimating the amount of gas in the galaxy by about one-third.

NGC 6334: Shedding Light On Starburst Regions
2013-06-05 13:00:40

Stars are formed in massive clouds of gas that are being compressed by some nearby event. Over time, the region will be consumed by the forming stars, leaving a cluster that will eventually drift apart. But what starts this process in the first place?

Predicting The End Of Stars Relies On How Much Sodium They Have
2013-05-29 12:58:12

An international team of astronomers published a paper in the journal Nature detailing how the amount of sodium in a star will help predict how its life will end.

Astronomy is more than merely using optical telescopes to take pretty pictures of distant nebulae and galaxies. Researchers also seek to understand complex systems in the universe by observing how objects interact and what types of radiation are produced.

Orion Reveals A Hidden Fiery Ribbon

The European Southern Observatory (ESO) has released a new image of the constellation of Orion showing part of the Orion Molecular Cloud.

Black Hole Birth In A Cosmic Flash

Stars sustain themselves by fusing elements in their core, producing even heavier atoms, releasing energy that keeps the immense force of gravity at bay. But eventually, the fusion process will no longer produce enough outward radiation pressure to sustain the star, and it will begin to collapse in on itself.

Sand Grains In Meteorite May Have Come From Milky Way-Forming Supernova
2013-04-21 07:31:06

Two tiny grains of silica discovered in primitive meteorites may have originated from the ancient supernova responsible for the formation of the solar system, according to new research published in the May 1 edition of Astrophysical Journal Letters.

Airborne Observatory Reveals Mystery Of Star Formation
2013-04-17 11:52:24

Using observations from an airborne observatory, NASA researchers have discovered new details on how massive stars form within a cloud of interstellar gas and dust.

Blue Supergiant Star Born In The Wild Discovered
2013-04-11 15:09:53

A duo of astronomers has discovered a Blue Supergiant star located far beyond our Milky Way Galaxy in the constellation Virgo

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...
