Sometimes progress in space science does not arrive with a flash. It comes quietly, through patient observation, and then settles into place. That is .

Astronomers have discovered an Earth-size planet orbiting an ultracool red dwarf star similar in size to Jupiter. The red dwarf, located some 55 light-years away, is 100 times less bright than the sun ...

Astronomers recently peered deep into space and found that an old, faint white dwarf named LSPM J0207+3331, located about 145 light-years away, is still consuming the rocky remains of its former ...

It's impossible to tell for sure how many stars there are in the Universe for the simplest reason that it's impossible to see them all, let alone count them. Some estimates, based on, well, more or ...

"While white dwarf stars may still give off some heat from residual nuclear activity in their outer layers, they no longer exhibit nuclear fusion at their cores. For this reason, not much ...

Recently, the James Webb Space Telescope ( JWST) took a stunning image of the star cluster known as Westerlund 2, located in ...

An international team of astronomers led by Dr Iris de Ruiter, now at the University of Sydney, has shown that a white dwarf and a red dwarf star orbiting each other every two hours are emitting radio ...

The sun is the biggest object in the solar system; at about 865,000 miles (1.4 million kilometers) across, it's more than 100 times wider than Earth. Despite being enormous, our star is often called a ...
