SINGAPORE, February 10, 2014 /PRNewswire/ -- The Agency for Science, Technology and Research (A*STAR) in Singapore inked a Memorandum of Understanding (MoU) with leading
The European Space Agency’s (ESA) billion-star surveyor mission is slowly beginning to see more clearly. The Gaia spacecraft took a test image of a dense star of clusters in the Large Magellanic Cloud to help fine tune its instruments.
In what is being described as landmark discovery about the origins of the universe, Tel Aviv University researchers report in the journal Nature that black holes, formed from the first-ever stars, heated the gas throughout space much later than previously believed.
OAKLAND, Calif., Jan. 30, 2014 /PRNewswire-USNewswire/ -- Chabot Astronomers are tracking the latest supernova about 12 million light years away.
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.
Several NASA spacecraft and Earth-based observatories, including the Hubble Space Telescope and the Chandra X-ray Observatory, are studying an incredibly close supernova that took place on January 21, officials from the US space agency announced on Friday.
Astronomers have located one of the most powerful black holes ever discovered – a gravity-intense region of space that is located nearly four billion light years from Earth and has prevented trillions of stars from forming.

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.
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...
