More than 50 times further from the Sun than Earth, the tiny dwarf planet Makemake is one of the last places you'd expect to find an intact gaseous atmosphere. Not only is it incredibly cold, being ...

TOI-6894 is now the smallest star known to host a transiting giant planet, with a radius 40% smaller than that of any previous such host. Prof. Jamila Chouquar, who was an astronomer at ULiege at the ...

Mercury appears to move backward (retrograde) in the sky. It's visible briefly in the evening sky, low on the western horizon. You'll need binoculars or a telescope to see it. Mercury will disappear ...

Many of the stars in the Milky Way galaxy are small, dim red dwarfs—stars much smaller than the sun in both size and mass. TOI-6894, located far away from Earth, is one of them. Astronomers previously ...
