The Latest Breaking News from Solar System

Comet C/2023 A3 Tsuchishan-Atlas visit is a link to our deep past and a slightly unnerving prompt to think about our future.

NASA has turned off one of Voyager 2's science instruments as power conservation becomes crucial for the interstellar exploring spacecraft located 12.8 billion miles from home.

Rather than carry many instruments with a vast array of purposes, CubeSats focus on a single, specific scientific goal.

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.
