For years, astronomers have known about the supermassive black hole at the center of our Milky Way galaxy, but these pictures from NASA's NuSTAR telescope show a rare view of the usually sleeping giant gobbling down a cosmic snack.

Scientists have located a galaxy that gives births to more stars in a day than ours does in a year.

How do you find a single star or constellation out of the vast expanses of space? What equipment should you use? It can all be a little intimidating.

Science editor Alan Boyle's Weblog: The spiral galaxy NGC 3521 is a swirling maw of raw power, measuring 50,000 light-years across. So why on earth do astronomers call it "fluffy"?

The night sky will put on a show in the coming days – and you don't need a telescope to appreciate it, according to University of Virginia astronomer Ed Murphy. The annual Perseid Meteor Shower, which typically produces 50 to 60 ...

It may not be possible to travel back in time, but seeing stars and galaxies as they looked millions or even billions of years ago is no problem thanks to telescopes, the closest thing we have to time machines.
