New high-contrast images from SPHERE show a stunning variety of debris disks shaped by collisions of tiny planet-building ...

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 ...

After decades of searching, astronomers may have finally stumbled upon the first moon known to exist beyond our solar ...

Astronomers may, for the first time, be confirming an exomoon in our universe, much like our moon, but outside our solar ...

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...

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 ...

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 ...

Almost all planets in our solar system have moons – why not exoplanets? Astronomers believe they have discovered the first ...

The NASA/ESA Hubble Space Telescope has made the first detection ever of an organic molecule in a planet orbiting another star. This breakthrough is an important step in eventually identifying signs ...

While Jupiter may be our planetary guardian angel, protecting us from harm, gas giants in other solar systems might actually wreak havoc on other exoplanets nearby. In our solar system, Jupiter's huge ...

Astronomers may have identified the first known exomoon, orbiting a Jupiter-like exoplanet, amidst 6,000 confirmed exoplanets.

An exoplanet in our celestial ‘neighborhood,’ located about 64 light-years away, was already known for its extreme weather. Any visitor willing to brave the 1,700 degree Fahrenheit temperatures would ...
