How Earth-like planets form around other planets is not quite known yet, albeit astronomers discover with each passing day that planets are forming in other distant star systems. According to a study presented last week, such a planet forming solar system seems to be forming around a series of stars located about 2,4... |

It is the closest star system to Earth, located only 4.4 light years away, and best of all, it may also have rocky planets like Earth orbiting around it. Alpha Centauri represents a triple system, composed of two average stars relatively similar to the Sun, and a red dwarf. It is argued whether we will be able to go ... |

We know much about stars, but even more to learn about them, otherwise we wouldn't try to replicate them here on Earth, would we? Stellar life, evolution and death are now becoming the points of interest for the European research program, which plans to study about 25 nuclear reactions that take place inside sta... |

Planetary nebulae have been first discovered some three centuries ago, but the astronomers of the time, being unable to clearly identify them, named nebulae by attributing them the name of "planetary", mostly because they seemed to have some resemblance to the planet Uranus. In the middle of the 19th century astronom... |

It would certainly appear so, and considering that our galaxy is filled with at least 200 billion stars, it would be no surprise if one of these rays of death would decide to hit our planet some day. However, the subject of discussion here is a star dubbed WR104, located about 8,000 light years from Earth in the Sagi... |

X-ray images of the Kes75 supernova remnant shows it to house what seems to be a rapidly spinning neutron star, commonly known as a pulsar, which could have been created in the outcome of the supernova explosion. Lying at a distance of about 20,000 light years away from Earth, Kes75's pulsar located close to the... |

According to new observations conducted with the Chandra X-ray Space Observatory, stars are no longer restricted to form inside the accretion disk of matter of a particular galaxy, but could easily start a star formation process far away if provided with the required amount of material. Such a process is currently ta... |

It's no secret now. Planets, stars may vary their magnetic fields so severely that could eventually reverse poles. Magnetic north becomes south and vice versa. Geologic evidences strongly suggest that even our planet could have reversed its poles a number of times in the past. The Sun's magnetic field orien... |

Forget about global warming, the ice ages, asteroids or any other impending disaster waiting to happen. Earth will burn! Literally! Astronomers approximate the age of the Sun to a rough 5 billion years and is mostly believed that it will continue to burn hydrogen at least as much time before becoming too unstable to ... |

ESA's Very Large Telescope surprised what seems to be a group of three large galaxies engaged into gravitational interactions with each other. The system lies 106 million light years away, in the direction of the Piscis Austrinus constellation, and is formed of NGC 7173, NGC 7174 and NGC 7176. Two of the galaxie... |

Similarly to most gas clouds in the universe, Rho Oph is mainly composed of molecular hydrogen gas, in which new stars may form. Rho Ophiuchi is one of the closest star-forming nebula to our solar system, lying only 407 light years away, in a region of space located between the Scorpius and Ophiuchus constellations. ... |

What do you see when you look upwards on a clear sky night? A few thousands stars maybe, some of the planets in the solar system, and the Moon... Looks kind of empty, doesn't it? The fact is that our galaxy is mostly cold empty space, as much as the universe. Nonetheless, astronomers from the Paul Scherrer Insti... |

When completed, it will be the biggest space telescope ever build, with a mirror twice as big as that of the famous Hubble Optical Space Telescope, and it will help astronomers study cold icy dust, resident in some of the most remote corners of the universe.

Lately, astronomers using the Very Large Telescope Interferometer have been able to probe parts of the material disk around a growing star, in order to determine how massive stars collect gas before becoming main sequence stars. The targeted object was a star in the Monoceros constellation, dubbed MWC 147. This parti... |

Supernova explosions are generally triggered by a unbalance between the gravitational force produced by the star and the thermonuclear fusion reactions. Nonetheless, astronomers argue that such explosions could be determined through more stronger interactions, like those between a white dwarf and a medium size black ... |

Monetizing on those who think they are good enough to make it to the well-lit stages is the idea BigShotLive founders had. A pretty good one indeed.

Dark matter is supposed to be all around us, nevertheless we have failed so far to make a direct observation of a dark matter cloud. The giant neutrino detector located in Antarctica, IceCube, will most likely receive an upgrade in order to produce direct evidence that dark matter can be found in the center of the Mi... |

We know organic molecules are scattered throughout most of the Milky Way, but it was about the time for the astronomers to find some in distant galaxies.

It seems that the shape of the evolving young solar system, forming a 35.2 billion kilometer structure in the form of a moth, is determined by the relative motion of the young stars through the interstellar space. As it is traveling through space, the developing solar system encountered a massive cloud of interstella... |

The universe originated in a Big Bang event more than 13 billion years ago, no doubt about that.

That's like having an 80 year old woman giving birth to a baby.

However, it seems that this is not always the case. Old stars, ... |
