The Latest Breaking News from Solar System

Beyond our solar system, countless alien worlds of lava, ice, water and noxious gas swirl through the cosmos. Here are some of the strangest exoplanets that scientists have discovered so far.

In the outer reaches of our Solar System, 5.7 billion kilometres from the Sun, lies the dwarf planet Pluto. Smaller than Australia, it is an icy world of mountains, glaciers and craters where the average temperature is –232°C.

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.
