Giant Gas Cloud Magnetic Shield Milky Way
2013-11-01 10:13:00

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have discovered a magnetic field deep within the Smith Cloud’s interior that may protect the giant galactic streamer of hydrogen gas during its projected collision with the Milky Way galaxy. The discovery, which was made using the Karl G. Jansky Very Large Array (VLA) and Robert C. Byrd Green Bank Telescope (GBT), could help explain how so-called high velocity clouds (HVCs) remain mostly intact during their mergers with...

[ Watch the Video: Is There A Supernova In Your Future? ] Brett Smith for redOrbit.com - Your Universe Online A supernova is one of the most brilliant events to take place in the universe and astronomers at The Ohio State University have determined we will see one in the Milky Way Galaxy within the next 50 years. While the odds of actually seeing a star explode with the naked eye is very low during that time span, a supernova would be visible to specialized telescopes in the form of...

Violent Youth Seeded The Universe With Iron
2013-10-31 05:07:20

April Flowers for redOrbit.com - Your Universe Online The universe underwent a turbulent and violent youth more than 10 billion years ago, as evidenced by iron spread evenly between galaxies in one of the largest galaxy clusters in the Universe. This violent youth was responsible for seeding the cosmos with iron and other heavy elements that are critical to life itself, according to the new study published in Nature. Scientists from the Kavli Institute for Particle Astrophysics and...

[ Watch The Video: Zooming in on PGC 6240 ] [ Watch The Video: Panning across PGC 6240 ] NASA/ESA Hubble Space Telescope PGC 6240 is an elliptical galaxy that resembles a pale rose in the sky, with hazy shells of stars encircling a very bright center. Some of these shells are packed close to the center of the galaxy, while others are flung further out into space. Several wisps of material have been thrown so far that they appear to be almost detached from the galaxy altogether....

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...
