An ominous-looking nebula named NGC 246 lurks in the constellation Cetus about 1,600 light-years away from Earth. It is ...

As we continue to break new ground in the field of cosmology, the importance of carefully categorizing the objects we see comes into focus. Part of this stems from the fact that, increasingly, we find ...

When a star runs out of fuel, it sheds its outer layers of gas and, if it doesn't explode in a supernova, forms a glowing shell of ionized gas that expands into space. Shells like these are known as ...

Many good things come in threes: the Three Musketeers, the Three Tenors, movie and book trilogies, and more. There seems to be something symmetrical, beautiful, and satisfying when using the power of ...

In their dying throes, some stars leave behind beautiful planetary nebulae — disk, spiral or even butterfly-shaped clouds of dust and gas (SN: 5/17/18). How these fantastically shaped clouds arise ...

Compass needles? Astronomers have discovered something weird in the Milky Way's galactic bulge - a population of planetary nebula are all mysteriously pointing in the same direction. They noticed the ...
