When the Hubble Space Telescope set its sights toward the binary star system HD 106906, astronomers found a world that could resemble the long-sought Planet X. For the first time, astronomers are able ...

With the breathtaking progress made in star and planet formation research aiming at far-away celestial objects, we can now investigate the conditions in environments around young stars and compare ...

A pattern in the movements of a brown dwarf that orbits a Sun-like star is likely to be caused by a moon. If confirmed, this would be the first exomoon, that is a moon orbiting a planet that in turn ...

NASA leverages the Hubble Space Telescope for all manner of scientific endeavors. Recently Hubble was used to pin down the orbit of a massive exoplanet called HD 106906 b that is 11 times the mass of ...

Hence, finding a planet that orbits really, really far from its parent star is a rare occurrence — so rare, in fact, that it’s hard to do even in our own solar system. Indeed, there is much evidence ...

Astronomers using the Hubble Space Telescope have surmised the color of another planet beyond our solar system. HD 189733b's azure blue globe resembles Earth from afar but don't be fooled. This is a ...

This graphic shows the orbit of the planet HD 20782 relative to the inner planets of our solar system. HD 20782's orbit more closely resembles that of a comet, making it the most eccentric planet ever ...

Astronomers have detected a three-ringed structure in the nursery of planets in the inner planet-forming disk of a young star. This configuration suggests two Jupiter-mass planets are forming in the ...

Observations with the European Southern Observatory’s (ESO) Very Large Telescope Interferometer (VLTI) found various silicate compounds and potentially iron, substances we also find in large amounts ...
