Astronomers using the Smithsonian's Submillimeter Array telescope have imaged the most detailed look yet of stellar nurseries within the Snake nebula.

Giant Gas Cloud Spotted By Telescope On Antarctica's Ridge A
2014-02-21 08:19:35

Using a telescope installed at the driest place on earth - Ridge A in Antarctica – a UNSW-led team of researchers has identified a giant gas cloud which appears to be in an early stage of formation.

Large Magellanic Cloud Completes One Rotation Every 250M Years
2014-02-18 13:13:39

Scientists using the NASA Hubble Space Telescope found that the Large Magellanic Cloud (LMC) completes a rotation every 250 million years. The team used Hubble to measure the average motion of hundreds of individual stars in the nearby galaxy, which is located about 170,000 light-years away from Earth.

Bipolar Jets Of Gas, Dust Created By Small Planetary Nebulae

Large stars can end their lives as violently cataclysmic supernovae. Small stars, in contrast, end up as planetary nebulae—colorful, glowing clouds of dust and gas. These nebulae were once thought to be mostly spherical.

Using Simulations To Chart The Forces Of The Early Universe
2014-02-06 10:13:28

Most scientific calculations need a reference point to be completed, but what if the calculations are for the beginning of the universe – where points of reference are somewhat ephemeral?

Massive Star Formation Mystery Solved
2014-01-28 04:04:20

Enormous young stars, which have over 10 times the mass of the Sun, shine brilliantly in ultraviolet wavelengths, energizing the gas around them, and it has long been a mystery why this superheated gas doesn't explode outwards.

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.

Hypervelocity Stars Escape Galaxy

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...
