redOrbit Staff & Wire Reports - Your Universe Online A team of astronomers have identified what is believed to be the sibling of our sun – a star thought to have been born from the same cloud of gas as the one that provides our solar system with light and warmth. According to Deborah Netburn of the Los Angeles Times, the sun’s so-called long-lost brother is slightly bigger and has a somewhat hotter surface temperature than the star around which the Earth orbits. However, an...

[ Watch the Video: Radio Wave Emission From A Pulsar ] John P. Millis, Ph.D. for redOrbit.com - Your Universe Online When a massive star, typically around 10 times the mass of our Sun, reaches the end of its main-sequence life, a series of events begins that eventually leads to a brilliant supernova. The shockwave from the event ejects most of the material into the surrounding interstellar medium, leaving a brilliant blanket of glowing gas that hangs in the sky for thousands of years....

Supernovae Used To Gauge The Power Of Cosmic Lenses
2014-05-02 06:38:10

redOrbit Staff & Wire Reports - Your Universe Online Two teams of astronomers have used the Hubble Space Telescope to observe distant exploding stars, and their research could help determine the power of naturally-occurring “cosmic lenses” than can be used to magnify objects in the far-off universe, NASA officials announced on Thursday. The scientists, who are working independently, have studied three supernovae using the phenomenon of gravitational lensing, which causes the...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online In the normal course of evolution, galaxies initially formed stars as clouds of hydrogen and helium collapsed. Eventually the density and temperature of the cores would ignite nuclear fusion, allowing them to shine during what we call the main sequence phase of their lives. Eventually, stars will fuse heavier and heavier elements, with stars like our sun eventually culminating as balls of carbon and oxygen – in varying...

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 Sun -- intensely hot, self-luminous body of gases at the center of the solar system. Its gravitational attraction maintains the planets, comets, and other bodies of the solar system in their orbits. The sun is actually a star of about medium size; it appears larger than the other stars because of its relative nearness to the earth. The earth's distance from the sun varies from 91,377,000 mi (147,053,000 km) at perihelion to 94,537,000 mi (152,138,000 km) at aphelion (see apsis). The...

Crab Nebula -- The Crab Nebula (Messier 1, NGC 1952) is the object the which started Charles Messier logging non-cometary objects on his Messier Catalog. It is the expanding cloud of gas thrown off in the explosion that gave rise to the 1054 supernova recorded by Chinese astronomers, now more than 6 light years across (the nebula is currently expanding at 1000 km/sec and the total mass of ejected material is about 0.1 solar masses). The supernova which produced it was bright enough to...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
