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.

Scientists are whittling down the possible landing sites for the ExoMars 2020 rover to explore the Red Planet's wet past, and have decided upon two final contenders.
The bluedot festival at Jodrell Bank Observatory has revealed the speakers who will be making up this year's science programme.
As part of the British Film Institute and Radio Times Television Festival, the BFI Southbank is hosting an afternoon on Sunday 9 April looking back on 60 years of The Sky at Night, and we have two pairs of tickets to give away.
A new type of star formation has been observed in the winds blowing from a galaxy's supermassive black hole. The young stars look different from their siblings who had a calmer upbringing, and could change what we know about the evolutionary history of galaxies.
While scanning a sky of merging galaxies, astronomers spotted a black hole speeding away from its galactic host, and gravitational waves could be the answer.
NASA studies of a Martian volcano have revealed it ran dry just as the dominant species on Earth was facing catastrophe.
Operation Avalanche is a Cold War comedy about a pair of CIA agents who find themselves faking the Apollo Moon landing. The film is out this week on DVD, and we're offering the chance for one lucky winner to win a copy, along with an astronaut bed spread worth £100.
A recently discovered giant Jupiter-like planet found a huge distance from its star appears to defy most theories of planetary formation. However, the host star's young age could help researchers unravel how not only this planet formed, but others like it throughout the Galaxy.
Simulations by NASA scientists show that the lakes on Saturn's moon Titan could be bubbly.
The 'Great Leviathan' 72-inch reflector, built during the 19th century at Birr Castle in Ireland, stands as a monument to humanity's desire to reach out to the cosmos. Iain Todd reveals how Irish engineering changed the face of astronomy.
Early spiral galaxies spun much slower than those in the current Universe, implying that dark matter did not dominate their mass at these times.
A supposed supernova has recently been exposed as a potential imposter, having suffered many violent eruptions over the 21 years preceding its final large outburst. It could be one of an entirely new class of stellar object.
Has there ever been life on Mars? Is Pluto a planet? What lies beyond Neptune? We put these questions to one of NASA's most experienced planetary scientists.
