Have Experts Finally Solved The Mystery Of Magnetars?
2014-05-14 06:55:50

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online When a massive star reaches the end of its life, it explodes in a brilliant supernova explosion. The remnant of the stellar core will usually form either a neutron star or a black hole. Occasionally, however, there emerges a third option: a magnetar. These exotic objects, share a lot in common with neutron stars. They are incredibly dense – second only to black holes in that regard – and spin very rapidly, though not...

2014-05-14 05:40:33

Brett Smith for redOrbit.com - Your Universe Online Using observations from multiple observation facilities, an international team of astronomers has identified a very unusual planet that takes around 80,000 Earth years to orbit its sun. The planet, dubbed GU Psc b, was determined to be 2,000 times the distance between the Earth and the Sun from its own star – a new record for exoplanets. The team said they were able to detect this highly unusual planet by detecting the light coming...

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...

The Tropic of Capricorn, alternately called the Southern Tropic, is a marker of the most southerly latitude on the Earth at which the Sun can be directly overhead. This occurs at the December solstice, when the southern hemisphere is tilted towards the sun at its maximum degree. It is one of the five major circles of latitude that mark maps of the Earth. It presently lies 23 degrees 26’ 16’’ south of the Equator. Currently, the Tropic of Capricorn is drifting towards the north at...
