Gravity Clues From Stellar Triple System
2014-01-06 03:39:45

redOrbit Staff & Wire Reports - Your Universe Online The discovery of a superdense neutron star in a stellar triple system has made it possible for researchers to collect the best measurements to date of the complex gravitational interactions present in these types of systems, according to a new study in Nature. Using the National Science Foundation's Green Bank Telescope (GBT), the study authors were able to locate the pulsar along with two white dwarf stars in a compact area...

Monstrous Stellar Collisions Not Expected To Occur Anytime Soon
2013-07-11 14:32:31

Lee Rannals for redOrbit.com - Your Universe Online Astrophysicists from the Astronomical Observatory of the Faculty of Physics at the University of Warsaw say the next collision of monstrous stars will not occur until billions of years from now. Three years ago, scientists discovered that the Magellanic Clouds host gigantic stars with between 200 and 300 times the solar mass  of our own Sun. Before then, astronomers believed that the biggest stars in the Universe did not...

Astronomers Use The Very Long Baseline Array To Set New Record
2013-06-13 14:46:36

ASTRON An international team of scientists led by astronomer Adam Deller (ASTRON) have used the Very Long Baseline Array (VLBA) to set a new distance accuracy record, pegging a pulsar called PSR J2222-0137 at 871.4 light-years from Earth. They did this by observing the object over a two-year period to detect its parallax, the slight shift in apparent position against background objects when viewed from opposite ends of Earth's orbit around the Sun. With an uncertainty less than four...

WASHINGTON, June 4, 2013 /PRNewswire-USNewswire/ -- A flash of light from a stellar outburst has provided a rare look at the 3-D structure of material ejected by an erupting nova. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Astronomers used NASA's Hubble Space Telescope to observe the light emitted by the close double-star system T Pyxidis, or T Pyx, a recurring nova, during its latest outburst in April 2011. A nova erupts when a white dwarf, the burned-out core of a...

Star Songs Plucked From The Cosmos
2013-06-01 05:44:51

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Harvard-Smithsonian Center for Astrophysics (CfA) have blended science, technology and art to create a unique new website that allows people to listen to original musical compositions crafted from cosmic x-rays. The Star Songs website was published by research associate Gerhard Sonnert, who worked with University of Glasgow postdoctoral student Wanda Diaz-Merced and composer Volkmar Studtrucker on the project....

Cosmic Test Upholds Einstein's Theory Of General Relativity
2013-04-25 13:56:53

Lee Rannals for redOrbit.com — Your Universe Online Astronomers have found a way to test Einstein's theory of gravity in ways that were not possible before now, thanks to new observations of a very unique system. A team used telescopes around the world to study the most massive neutron star confirmed so far, orbited by a white dwarf. The scientists wrote in the journal Science that so far the new observations match up with Einstein's predictions for general relativity....

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Click here to stream "How Stars Die And Black Holes Form": Your Universe Today Podcasts (Or right-click on the above link to download the file to your computer) Black holes are among the most exotic, mysterious and perplexing objects in the Universe. They are swallowers of light, destroyers of stars and the engines that drive our galaxies. Some believe they could even hold the key to interstellar travel and may perhaps...

Merging Black Holes Could Reveal Their Flashy Secrets
2012-09-29 08:09:37

[ Watch the Video: Black Holes Crash, Merge in New Simulations ] April Flowers for redOrbit.com - Your Universe Online Einstein predicted gravitational waves almost 100 years ago. According to his theory, whenever massive objects interact, they produce distortions in the very fabric of space and time that ripple outward across the universe at the speed of light. Modern astronomers have found indirect evidence of these waves, but so far they have eluded direct detection. Greater...

black hole
2012-09-18 05:29:06

April Flowers for redOrbit.com - Your Universe Online Recent research from the University of Cardiff has found that the dying tones of black holes reveal the cosmic crash that caused them to form. Black holes are regions of space where gravity is so strong that not even light can escape. Usually, they are the evolutionary ending of stars that were 10 to 15 times larger than our sun. After these stars undergo a supernova event, sometimes the remnant will collapse in on itself, creating a...

NASA’s Kepler Space Telescope Discovers Two Planets Orbiting Binary Star System
2012-08-29 08:58:00

Lawrence LeBlond for redOrbit.com - Your Universe Online Astronomers working with NASA´s Kepler mission have found the first evidence of multiple planets orbiting a binary star system. The discovery shows that planetary systems can form and survive in chaotic environments around a binary star system. Furthermore, the discovery suggests that earth-like planets can also exist in the habitable zone of their stars. The discovery was announced this week at the XXVIII General Assembly of...

Georg Friedrich Julius Arthur von Auwers (September 12, 1838 "“ January 24, 1915) was a German astronomer born in Göttingen, Germany. He attended the University of Göttingen and worked at the University of Königsberg. Auwers specialized in astrometry, making very precise measurements of stellar positions and motions. He detected the companion stars of Sirius and Procyon from their effects on the main star's motion, before telescopes were powerful enough to visually observe them....

Cygnus Constellation -- Cygnus (the swan) is a northern constellation. It was one of Ptolemy's 48 constellations, and is also one of the 88 modern constellations. Because of the pattern of its main stars, it is sometimes called the Northern Cross (in contrast to the Southern Cross). The bird extends over the summer Milky Way, appearing to fly south. Notable features Cygnus contains several bright stars. Deneb, α Cygni, is an extremely brilliant star, very prominent despite...

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...

T Tauri -- T Tauri stars are a class of stars thought to represent extremely young pre-main sequence stars, in an early stage of life. They are seen near many molecular clouds in our galaxy. The first ones were found in 1945, identified by their optical variability and strong chromospheric lines. T Tauri stars have masses and temperatures similar to the Sun, but are significantly brighter. They have fast rotation rates, typically with a period of a few days, compared to a month for...

Star Catalogue -- In astronomy, many stars are referred to simply by catalogue numbers. There are a great many different star catalogues which have been produced for different purposes over the years, and this article covers only some of the more frequently quoted ones. Most of the recent catalogues are available in electronic format and can be freely downloaded from NASA's Astronomical Data Center and other places (see links at end). Historical Catalogues Although no longer in...
