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

Brett Smith for redOrbit.com - Your Universe Online 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. The star, known as WX“¯UMa, is a so-called flare star, a class of stars which can become 100 times or more brighter within a few seconds or minutes. These flares appear to be randomly...

Astronomers Identify New Type Of Variable Star
2013-06-12 05:07:07

[ Watch the Videos: The Star Cluster NGC 3766 | Zooming in on the Star Cluster NGC 3766 ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers writing in the journal Astronomy & Astrophysics say they have discovered a new type of variable star. The Swiss astronomers discovered the new class of variable stars by measuring minute variations in stellar brightness. The new results are based on regular measurements of the brightness of more than three thousand stars in the...

New Planet Hunting Technique
2013-06-10 12:43:01

Lee Rannals for redOrbit.com - Your Universe Online Sponsored by the International Astronomical Union (AIU), a team of astronomers is working on a technique capable of detecting faint dust clouds around other stars where Earth-like planets could be hiding. This new technology could dramatically improve the odds of discovering planets with conditions suitable for life. "Current technology allows us to detect only the brightest clouds, those that are a few thousand times brighter than the...

Cats Paw Nebula Baby Boom
2013-06-06 13:58:02

Lee Rannals for redOrbit.com - Your Universe Online Astronomers presented research on Wednesday at the American Astronomical Society (AAS) about how the Cat's Paw Nebula is experiencing a "baby boom." The team said the nebula, or NGC 6334, is forming stars at a more rapid pace than the Orion Nebula, which is one of the closest stellar nurseries to Earth. "It might resemble a 'mini-starburst,' similar to a scaled-down version of the spectacular bursts sometimes seen in other...

The Sun Was A 'Feisty' Character In Its Younger Days
2013-06-06 12:57:33

Lee Rannals for redOrbit.com — Your Universe Online Astronomers said during a press conference at a meeting of the American Astronomical Society that when our Sun was in its infancy, it was active and "feisty." The team said that when the Sun was young it was growing in fits and burping out bursts of X-rays. They came to this conclusion after studying another young star in our galaxy known as TW Hydrae, which sits about 190 light-years away in the southern constellation Hydra the...

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

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online 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? Often these regions of star formations -- known as starburst regions -- are found in distant galaxies where the activity level is very high. But this presents a problem:...

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...
