Astronomers have discovered more than 3,000 planets around other stars, so far. In the first of a two-part series we look at how they find world’s elsewhere in the universe.
The number of known exoplanets doubled this week to more than 3,200. But why have only a handful of these those new planets caught people’s imagination?
We don’t need to look for Earth-like planets exclusively around Sun-like stars. Tiny, dim TRAPPIST-1 has only 11 percent the diameter of the Sun and is much redder.
Stargazing seems such a quiet, calm activity. But whether our eyes can see or not, those stars out there are in constant flux. Time-domain astronomy studies how cosmic objects change with time.
Extragalactic astrophysicists want to know how and why galaxies stop forming stars, change their shape and fade away. With help from citizen scientists, they’re figuring it out.
They’re are the overachievers of the universe: incredibly dense but very small when compared to others stars. So how much do we know about the extreme behaviour of neutron stars?
Astronomers aren’t mere stargazers these days. One researcher explains the ins and outs of how they collect data from far-off galaxies and what they do with it back at the office.

What happens to a galaxy when it runs out of the stuff needed to forge new stars?
The best observations yet of a mysterious gas cloud that was heading for the black hole at the hear of our Milky Way reveal it may have more stellar origins.
The universe is such a big place that it is easy to get baffled by the measurements that astronomers make. The size of UY Scuti, possibly one of the largest stars we have observed to date, is certainly…

A detailed study of comets orbiting the young nearby star Beta Pictoris is published today in the journal Nature, and it reveals striking similarities to the comets found in our solar system. Over the…
