A team has made some intriguing discoveries in the outer regions of the Milky Way. Astronomers mapped the fringes of the sparse halo that envelops our home galaxy, and found the wake of a dwarf galaxy on an eventual collision course with the Milky Way.

A growing body of evidence points to the Red Planet being much bluer in its ancient past. Where all that water went is a key question, with many scientists believing it escaped into space. New analysis suggests another answer: it retreated underground.

A quantum internet would be much faster and more secure than the regular web – and now it may be one step closer to reality. Scientists have used quantum teleportation to send information over long distances, with a higher fidelity than ever before.

Voyager 2 has been going strong for over 40 years, but it’s beginning to show signs of its age. NASA is reporting that a fault has caused the spacecraft to lock itself down in safe mode, as engineers work to get it back up and running again.

In NGC 6946, better known as the Fireworks galaxy, an extremely bright flare of X-rays was seen to appear and disappear within a matter of weeks.

This week DARPA kicks off a competition called the Subterranean Challenge, where hordes of robots are unleashed into caves and tunnels to test how well they can autonomously navigate these environments. One team's designs could lead to robots that explore caves on other planets.

A solar eclipse is an amazing sight to behold, and it's an astronomical event that's not limited to Earth. NASA's Curiosity rover has captured images of Mars' two moons, Phobos and Deimos, as they passed between the Red Planet and the Sun.

Earth’s pleasant, life-giving atmosphere is turning out to be somewhat of an oddity. To get a better understanding of exoplanets, a team at NASA’s Jet Propulsion Laboratory (JPL) has recreated one of these alien atmospheres in the lab.

NASA’s ongoing Operation IceBridge has found a gigantic cavity underneath Thwaites Glacier in West Antarctica, which shows that the area has suffered even more drastic ice loss in recent years than previously thought – and it’s accelerating.

A new study shows how fluoride might be put to work in better batteries. Researchers at Caltech, JPL, Lawrence Berkeley National Lab and the Honda Research Institute have developed fluoride-based batteries that could potentially last much longer than existing lithium-ion-based devices.

The galaxy W2246-0526 sits 12.4 billion light-years from Earth – almost the entire radius of the observable universe – and is the most luminous galaxy ever discovered, with the brightness of 350 trillion Suns. Now, astronomers have found that W2246-0526 is cannibalizing three neighboring galaxies.

Back in May, NASA launched some extra luggage along with the Mars InSight lander – two briefcase-sized CubeSats named MarCO-A and MarCO-B. These two little spacecraft are the first of their kind to venture into deep space, and now they've sent us back their first glimpse of the Red Planet.
