Tatooine-Like Planets May Be More Common Than We Thought

For decades, astronomers have assumed that Earth-like planets cannot form around binary stars on account of wacky gravitational effects. Which, for Star Wars fans, was a total downer. But a new study suggests that not only is the formation of Tatooine-like planets very much possible, they may actually be quite common. » 4/01/15 12:11pm 4/01/15 12:11pm

This Is Probably The Weirdest Binary Star System Ever Discovered

There's some strange things floating around in our galaxy, but this has to be one of the weirdest. A double star system with misaligned protoplanetary disks around 450 light-years from Earth has been discovered, potentially explaining why some exoplanet orbits can be wildly eccentric. » 7/31/14 4:40pm 7/31/14 4:40pm

An entirely new class of galaxy-escaping hypervelocity stars

Every once in a while, the Milky Way's supermassive black hole flings a wayward star into intergalactic space at speeds reaching 2 million miles per hour. But astronomers have now discovered a surprising new class of "hypervelocity stars" that can escape the galaxy — and they don't need the galactic core to do it. » 1/10/14 8:00am 1/10/14 8:00am

The first picture ever of a Tatooine-like binary star system. Maybe.

What you're looking at here is the first direct imaging of a planet orbiting a pair of stars. Trouble is, the planet is so large — about 12 to 14 times the size of Jupiter — that it might actually be a failed star, a so-called brown dwarf. But for now, the astronomers are cool with calling the massive object a planet. » 3/26/13 10:56am 3/26/13 10:56am

Astronomers discover binary stars in 'impossibly' tight orbits

A team of scientists using the United Kingdom Infrared Telescope (UKIRT) in Hawaii have found four different pairs of binary systems whose stars are so close to each other that it takes them less than four hours to orbit one another. Previous estimates indicated that stars shouldn't be allowed to do this — they… » 7/06/12 5:00pm 7/06/12 5:00pm
