Using a galaxy located two billion lightyears from Earth as a sort of cosmic magnifying class, astronomers been able to observe an exploded star that could help measure the expansion rate of the Universe.
A newly-discovered exoplanet just 40 lightyears from Earth could be the best candidate we know of in the search for signs of life outside our own planet.
An asteroid the size of Gibraltar passed by the Earth on 19 April, and will continue to grow in brightness for several nights giving a fantastic observing opportunity.
The newest observations from ALMA have confirmed that the Solar System object 2014 UZ224 is a dwarf planet.
Jupiter may have been hiding a second great spot for over a thousand years. New images from the Very Large Telescope have revealed a colossal Great Cold Spot, a cool patch in the planet’s polar atmosphere that appears to be created by the planet’s aurora.

Gravitational lensing has allowed astronomers to spy on a 'typical' galaxy as it was in the days of the early Universe. This find will allow them to study the most numerous kind of fledgling galaxy present during this highly important era.
When selecting your observing site, looking down is as important as looking up, writes Jon Powell.
The remnants of a collision between two infant stars has been captured by ALMA. The beautiful images could help astronomers understand how such stellar crashes govern the rate at which our Galaxy forms stars.
An atmosphere has been detected for the first time around a planet with a mass and radius similar to Earth.
The Sun's activity may be generating a transient atmosphere on dwarf planet Ceres, say NASA scientists.
A new documentary looks at the unsung heroes of Apollo: the mathematicians and engineers who worked at Mission Control to bring their comrades safely back to Earth.
The Sun has woken up, and not just to supply the UK with sunshine, as our selection of readers' solar images show.
The Sun has been surprisingly active over the weekend, with flares as strong as M5.7 errupting from its surface.
With the deadline approaching on 7 April, now's the time to submit your best astro images for the Insight Astronomy Photographer of the Year 2017 award, in the hope of winning that £10,000 prize.
Mars once had an atmosphere and running water, but that all changed as a result of the power of our Sun, according to new NASA data.
Four unknown bodies are being examined in the hope of finding the hypothetical ninth planet of our Solar System beyond the orbit of Neptune.
As part of this year's Stargazing Live from Down Under, we find out how Aboriginal Australians used the night sky to find their way across the dusty outback – even when the stars were missing.
