Astronomers Discover The Earliest Echoes Of The Big Bang
2014-03-17 13:23:58

Lee Rannals for redOrbit.com - Your Universe Online Astronomers publishing a paper in the journal Nature say they have found the first direct evidence that gravitational waves rippled through the early Universe during the inflation period. Scientists using the NASA-developed detector technology on the BICEP2 telescope at the South Pole found the strongest confirmation yet of cosmic inflation theories, which say the universe expanded by 100 trillion trillion times in less than the blink...

Rare Binary White Dwarf Systems
2013-12-20 08:30:50

John P. Millis, PhD for redOrbit.com - Your Universe Online Nearly a half-century ago, astronomers discovered a strange star in the Canes Venatici constellation. It was later determined that the unusual properties of the object arose because it was not an isolated star at all, but rather a very tight binary system. With an orbital period of 18 minutes – for comparison the orbit of Mercury around the Sun takes about 88 Earth days – the individual members of the system are incredibly...

Brett Smith for redOrbit.com - Your Universe Online Based on observations from the South Pole Telescope, a team of international scientists has found subtle patterns in the cosmic microwave background called B-mode polarizations, according to a report in Physical Review Letters. “The detection of B-mode polarization by South Pole Telescope is a major milestone, a technical achievement that indicates exciting physics to come,” said study author John Carlstrom, a deputy director of...

ESA Missions Will Seek To Understand The Evolution Of The Universe
2013-11-29 07:25:17

April Flowers for redOrbit.com - Your Universe Online The European Space Agency (ESA) announced today that the hot and energetic Universe and the search for elusive gravitational waves will be the focus of their next two large science missions. Bridging fundamental astrophysics and cosmology themes, both topics will closely study the processes that are crucial to the large-scale evolution of the Universe and its underlying physics. L2, the second large-class mission in ESA's Cosmic...

Revealing New Information On Strength Of Black Hole Mergers
2013-11-08 07:13:10

Lee Rannals for redOrbit.com - Your Universe Online The Commonwealth Scientific and Industrial Research Organization (CSIRO) in eastern Australia has helped reveal new information about the strength of black hole mergers. Giant black holes throughout the universe sometimes pair up and merge, sending out gravitational waves that ripple across space and time. Albert Einstein predicted that these waves exist, but scientists have yet to directly detect one. Astronomers were able to...

Two Black Holes Form, Fuse Together After Star Collapses
2013-11-07 07:17:18

[ Watch the video: Supermassive Star Collapses, Forms Two Black Holes ] April Flowers for redOrbit.com - Your Universe Online Black holes are massive objects in space that have gravitational forces so strong that not even light can escape them. These objects, swirling at the centers of galaxies, also come in a variety of sizes. On the small end of the spectrum are stellar-mass black holes, which are formed during the deaths of stars. On the largest end are supermassive black holes....

Colliding Galaxies Create Supermassive Black Holes
2013-10-23 16:17:25

John P. Millis, PhD for redOrbit.com - Your Universe Online Normal black holes – a bit of a misnomer in and of itself as there is little that is “normal” about black holes of any type – are typically on the order of a few times the mass of our Sun or less. These objects are believed to result from the collapse of a massive star, an incredibly energetic event we call a Type II Supernova. But there exists at the center of virtually every galaxy we have studied a black hole of such...

April Flowers for redOrbit.com - Your Universe Online Without understanding the internal structure in detail, it is still possible for scientists to learn a tremendous amount about neutron stars and quark stars, according to a new study from researchers at Montana State University. "The stars could be the softest or the hardest in their kind, and it wouldn't matter," said Nico Yunes, assistant professor in MSU's Department of Physics. Yunes and his colleague, postdoctoral scholar Kent...

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...
