Is planet nine actually an exoplanet? New study investigate the prospects for the capture of Planet 9 from other stars during the dissipation of the Sun’s birth cluster. Read More

New Analysis Of The Second Most Distant TNOs (225088) 2007 OR10

March 11, 2016 | 1

Using analysis provided by NASA’s Kepler space telescope — K2 extended mission — and thermal infrared data provided by ESA’ Herschel Space Observatory, a team of scientists found that (225088) 2007 OR10 is likely to be larger in size and darker than previously thought. Read More

Astronomers Found A Jupiter-Like Planet Orbiting Sun-Like Star. Twin Solar System?

July 17, 2015 |

So far, NASA’ Kepler Space Telescope and other exoplanet survey missions have found thousands of alien planetary systems with nearly 2,000 confirmed exoplanets. Read More

Scientists Found Kuiper Belt Twin Encircling Nearby Star

May 31, 2015 |

Using the Gemini Planet Imager, scientists have discovered a disc-shaped bright ring of debris surrounding a nearby Sun-like star called HD 115600, a planetary system that resembles our own solar system in its infancy. This discovery may help scientists to understand how our solar system formed and developed billions of years ago. Read More

Astronomers Find Basic Ingredients For Life In Infant Star System

April 13, 2015 |

For the first time, scientists have detected the presence of complex organic molecules, the building blocks of life, in a rotating disk of dense gas surrounding a young star (infant star system). This finding suggests, again, that the conditions that spawned life on Earth are not unique in the universe. Read More

Red Dwarf Star Passes Through Our Solar System 70000 Years Ago

February 18, 2015 |

Astronomers say a red dwarf star and its brown dwarf companion passed within 0.8 light-year of our own sun 70,000 years ago, moving through the comets in the outer reaches of the Oort Cloud that surrounds our solar system. In cosmic terms, that’s almost a close shave, astronomers say; our nearest neighbor star, Proxima Centauri, is a comfortable 4.2 light years away from us. Read More

New Video of Pluto and Charon ~ The Wobbly Dance

February 14, 2015 |

A short time-lapse “movie” was shot of Pluto and its largest moon, Charon. The images were taken by Long-Range Reconnaissance Imager (LORRI) on NASA’s New Horizons spacecraft, which is closer to Pluto than any spacecraft has ever been. Read More

Top 5 Solar System Mysteries That Still Baffling Astronomers

February 14, 2015 |

Despite all the information we’ve discovered from our telescopes and outer space missions, there are still many puzzles to solve in our own solar system. Sometimes, it seems the more we learn, the more mysteries we uncover. Read More

Oldest Star System in Galaxy Discovered by NASA ‘could Point to Extremely Advanced Alien Civilisations’

January 27, 2015 |

Astronomers have found a star system that bears striking resemblance to our inner solar system. Read More

What would Earth Look Like with a Different Sun?

January 25, 2015 |

It’s hard to imagine what life would look like if we were rotating around some star other than the sun. So the Russian Federal Space Agency imagined for us. And it looks awesome. The video above puts different stars at the center of our solar system, envisioning Earth in a very different light. Five different lights, actually. Read More

Astronomers: There are at Least Two more Large Planets Beyond Pluto

January 16, 2015 | 4

If you’ve been having trouble remembering how many planets are in the solar system after Pluto’s unceremonious demotion, get ready to revise your understanding of the universe again. According to the calculations of scientists at the Complutense University of Madrid (UCM, Spain) and the University of Cambridge (United Kingdom) not only one, but at least two planets must exist to explain the orbital behaviour of extreme trans-Neptunian objects (ETNO) Read More
