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.
Building a tiny starship may be doable. The big challenge will be making sure it survives all the hazards in interstellar space.
In the search for life on other planets in the universe we need to find the right kind of star, and it needs to have the right kind of space weather.
The hunt to find the source of the gravitational waves detected by LIGO on the sky is only just starting.
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.
Dust from pulverised comets rather than an alien megastructure could explain odd flicker of distant star.
Think our Sun’s big? Prepare to be dazzled by the real galactic heavyweights.
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?
Astronauts living on the ISS get to experience the wonders of the universe’s natural phenomena like no one else.
Our universe’s most exciting days are well behind us, with new research showing the universe is now slowly but surely dying.
Why the Breakthrough Listen project is a step in the right direction in our hunt for life beyond Earth.
Astronomers have spotted the earliest known stars in the universe, belonging to a class of chemically pure stars that may never have been seen before.
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…
What makes our sun shine has been a mystery for most of human history. Given our sun is a star and stars are suns, explaining the source of the sun’s energy would help us understand why stars shine. An…
An American telescope has detected a white dwarf star with a diamond core that could be the coldest of its kind ever discovered…
