The Latest Breaking News from Solar System

A new study reveals that Charon, Pluto's largest moon, is getting bombarded by lots of cosmic energy. NASA's Webb Space Telescope found the telltale signs.

Astronomers have discovered a low-mass "sub-Earth" planet orbiting the closest solo star to the solar system, Barnard's star, that has a year lasting just three Earth days.

Most CubeSats weigh less than a bowling ball, and some are small enough to hold in your hand. But the impact these instruments are having on space exploration is gigantic. CubeSats – miniature, agile and cheap satellites – are revolutionizing how scientists study the cosmos.

A newly discovered Earth-size world orbiting a dead white dwarf star gives scientists a hint of what the solar system may look like in billions of years.

"If there are lots of black holes out there, some of them must surely pass through our backyard every now and then."

New observations from the MeerKAT radio survey suggest our estimates of the cosmic dipole effect are actually in line with the large scale structure of the universe.

Tiny black hole "bullets" left over from the Big Bang could be passing through Mars at speeds in excess of 7,000 times the speed of sound, causing the Red Planet to "wobble."

Eleven objects found at the extremities of the solar system could mark the location of a 'Kuiper Belt 2.'

If microscopic black holes born a fraction of a second after the Big Bang exist, then at least one may fly through the solar system per decade, generating tiny gravitational distortions that scientists can detect.

A passing star may have kicked the weird moons of giant planets like Jupiter and Saturn into place, new research suggests.

The rings of Saturn are some of the most famous and spectacular objects in the Solar System. Earth may once have had something similar.
