This image shows what the largest star in the Eta Carinae binary system might look like when it blows up, in the near (astronomical) future. This may translate into a few million years from now, but that is a very brief time in universal terms.The largest star in the system has already experienced a massive explosion... |

Circumbinary planet systems (CBPS) are made up of one or more planets orbiting a binary star system. Until now, these were believed to be very rare, but recent discoveries from the NASA Kepler Telescope appear to indicate that millions of such systems may exist in our galaxy alone.
The planet-hunting telescope was ... |

A recent investigation of the 55 Cancri binary star system has revealed that five of the planets surrounding the largest star do somersaults in their orbits, over the course of millions of years. One of the gas giants leads the way, forcing the other four to follow suit.
The planet in question, called 55 Cancri d, ... |

This distant spiral galaxy, called NGC 300, has recently been shown to contain an impressive binary system at its core. Unlike other such systems, this one is made up of a relatively large star, which orbits around a black hole.
Such setups are very rare, because they are very difficult to form. The presence of a ... |

Astronomers operating the NASA/ESA Hubble Space Telescope have just released a new image of a cosmic structure called PN G054.2-03.4, but which is known among experts at the Necklace Nebula.The photos shows the object in all of its glory. It appears to be extremely bright, which enables astronomers to peer deeper wit... |

Astronomers say that they were recently able to confirm the existence of two Jupiter-class exoplanets in orbit around a pair of stars called a binary system. This was thought to be nearly impossible until now, due to the interactions that develop in such a cosmic structure. The stars in this particular binary pair ar... |

Researchers have recently managed to extract new knowledge on the violent binary star system HM Cancri, and to determine that its members spin around each other in a mere 5.4 minutes. This is extremely fast for such a cosmic pair, which is made up of two white dwarfs, stars about the size of our Sun that have reached... |

Astronomers announce the discovery of the farthest black hole ever found in the Universe, the relic of a defunct star that collapsed under its own weight a long time ago. There are a number of features that make this particular space structure unique, including the fact that it is the second most massive of all simil... |

The aptly named RCW 38 is one of the densest star clusters known, located some 5,500 light-years away, in the direction of the constellation Vela. The embedded cluster, termed that way because the immensely vast amounts of dust and gas that trigger star formation still envelop developing formations, is one of the str... |

Since astronomers first discovered galactic mergers, theorists have argued that one of the results of such a merger would be the creation of a binary black hole system, much similar to a binary star system. Thus far, their quest for one has proven futile, but now an extensive study from the Sloan Digital Sky Survey t... |

Over the last decades, our solar system has been experiencing a massive sand storm, not unlike those that can be found in the desert. All the planets orbited the Sun in a halo of sand particles that is now considerably larger than it was a century ago. The reason for these large amounts of cosmic debris has kept astr... |

For a long time, astronomers studying the formation of massive stars have been puzzled at how the giant celestial bodies, some 120 times larger than our Sun, can expand without “chasing away” the dust and gas clouds that feed their growth. According to a new theory, this relative stability can be explaine... |

Supernova SN 2007on was discovered last year in the location of what previously was a binary system, composed of at least one white dwarf and another stellar companion, most likely a regular slightly more massive star or possibly a second white dwarf. It is now known that the supernova is a Type Ia, meaning it was de... |

Astronomers reveal the mystery behind the BP Piscium star located in the Pisces constellation, an old star that appears to have recently spawned a new star formation process. A new study reveals that the accretion disk of matter spinning around it formed during a stellar collision and merging of two stars. Usually, ... |

Previously, astronomers believed that only black holes are capable to emit powerful X-ray jets, but a new study conducted at the Penn State University shows that, in fact, any class of object may be able to some extent to form powerful X-ray jets. A newly discovered neutron star seems to present features relatively s... |

Though the respective area of sky - where the new X-ray source was discovered - had been surveyed back in 2003, data showed that it hadn't been there at the respective moment. In March of last year, the Chandra X-ray Space Telescope, scanning the general direction of the galaxy Centaurus A located about 14 billi... |

An unique multiple-star system located in the constellation of Aquarius, about 166 light years away, consisting of four young stars orbiting rapidly in tight formation around each other, may provide new insight in the process of star formation and evolution. Dubbed BD -22°5866, the newly discovered system represents ... |

How massive could a black hole in the universe be? Well, according to astronomers, they can get pretty big. At the American Astronomical Society meeting which took place yesterday, astronomers proposed that most of the massive black holes in the universe could surpass 18 billion times the mass of the Sun! Previously... |
