NASA's Cassini spacecraft has captured a stunning image of the spinning vortex of Saturn's north polar storm.
You are not meant to stare at the sun. But when it looks like this it is hard to take your eyes off it.
The most powerful solar flare of the year so far has erupted from the sun, towards Earth, knocking out radio communications.
Two NASA astronauts are set to undertake a 'spacewalk' to fix an ammonia leak at the International Space Station.
Tom Marshburn and Chris Cassidy will step into space for around six hours to attempt to mend the "very serious" leak.
A NASA satellite has captured a volcano in south-east Asia spewing ash into the air, as seen from space.
The image of the Paluweh volcano in Indonesia's Flores Sea was taken on 29 April by the Landsat Data Continuity Mission satellite.
Timelapse footage taken by space agency NASA shows a solar eruption taking place just around the edge of the sun. A coronal mass ejection (CME), as it is known, can shoot over a billion tons of particles into space at over a million miles per hour.
NASA's Curiosity rover is soon to begin conducting science experiments again after a quiet period known as 'solar conjunction'.
This happens when Mars and Earth are on opposite sides of the sun. To avoid communications between NASA and the rover being interrupted, Curiosity was put into a kind of standby mode.
Just before this happened, around 11 days ago, the rover's Twitter account reported:
In the last few minutes, it was reported that the Curiosity rover is now ready for new commands:
I'm healthy & almost ready to resume science ops. With solar conjunction nearly over, my team plans to send new commands May 1From @MarsCuriosity on Twitter:
NASA have released a new image of a comet giving astronomers the best view yet of Comet (C/2012 S1) ISON during its first visit to our solar system.
The comet’s dusty coma, or head of the comet, is approximately 3,100 miles across, or 1.2 times the width of Australia. A dust tail extends more than 57,000 miles, far beyond Hubble’s field of view.
A privately-owned rocket built in partnership with NASA to take cargo to the International Space Station has blasted off for its first test flight.
The 13-story Antares rocket took off from a launch pad in Virginia. Ten minutes later it deposited its payload - a 8,380-pound dummy capsule - into an orbit 158 miles above the Earth.
The team behind the rocket, Orbital Sciences and privately owned Space Exploration Technologies hold NASA contracts worth a combined £2 billion to fly cargo to the space station. NASA turned to commercial suppliers after retiring the space shuttles in 2011.
International Space Station Commander Chris Hadfield said: "Wahoo, that's super... Congratulations to all concerned. That bodes well for all of our futures."
The latest planetary discoveries by the Kepler satellite bring us "a bit closer" to finding a planet similar to Earth, says NASA's John Grunsfeld:

The Kepler spacecraft has certainly turned out to be a rock star of science.
The discovery of these rocky planets in the habitable zone brings us a bit closer to finding a place like home.
It is only a matter of time before we know if the galaxy is home to a multitude of planets like Earth, or if we are a rarity.
NASA scientist Tom Barclay says new discoveries by the Kepler satellite mean habitable planets are no longer just "theoretical":
T. Barclay: These discoveries suggest that there are many habitable, small planets.From @NASAKepler on Twitter:
