Add Yahoo as a preferred source to see more of our stories on Google. Some of the most promising places to look for extraterrestrials have remained, so far, mostly hidden from astronomers. Now a ...

This is a brilliant question because the notion of an orbit is counterintuitive. We know that massive objects (really, any objects with mass) gravitationally attract other massive objects; Newton's ...

Astronomers have confirmed a giant planet orbiting a tightly bound pair of young stars, marking a first in direct exoplanet imaging. The planet, known as HD 143811 AB b, is the closest-in world ever ...

Andrew Winter's team at Queen Mary University of London analyzed fifteen disks around young stars. They used the ALMA array to measure Doppler shifts of carbon monoxide. This technique reveals the ...

Astronomers have detected an Earth-size planet candidate orbiting a nearby star once a year, making it a promising target for ...

When you see art of our solar system as the planet orbit the sun, you may notice that Earth's orbit has a tilt. It is not a perfect circle. What's more, Earth is not the only planet that displays such ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...

Planet hunters have grown used to strange worlds, but a handful of discoveries now point to something even more radical: giant planets that loop around their stars on orbits so skewed they almost defy ...

In a discovery that's fit for a movie, Northwestern University astronomers have directly imaged a Tatooine-like exoplanet, orbiting two suns. While obtaining an image of a planet beyond our solar ...
