LightSail 2 has successfully deployed its solar sails. Shortly after 12:00 pm PST (19:00 UTC) The Planetary Society tweeted that the sails were deployed, and that the spacecraft was sailing with sunlight.

A historic heat wave is bringing unprecedented temperatures to Western Europe, and is poised to expand northeastward to Scandinavia and into the Arctic by late this weekend.

There are a lot of myths about electric cars - one of which is electric cars are not that green after all, and we're here to figure out if it's the case or not. I'm Lilly and this is my voice you hear in our weekly digests.
If you have any questions for me…

The Arctic is warming twice as fast as the rest of the planet, and after the hottest June ever recorded on Earth, the region is literally on fire.

I am a scientist who researches climate hazards. This week I have published research on the potential for a catastrophic cyclone-heatwave combo in the global south.

The waxing and waning of sunspots forms part of our Sun's natural cycle, but it's a phenomenon astronomers still don't fully understand. Now, new research has revealed that particular "terminator" events are what brings sunspot cycles to an end, an

If this headline looks familiar to you, that's because we wrote an almost identical one in 2016. Except back then, we were freaking out because we'd used a year's worth of Earth's resources by August 8. Now, three years later, we've accomplish

The probable culprit behind a mysterious cloud of radioactive particles detected floating above much of Europe in 2017 appears to have been identified.

Indian tiger numbers are up, according to one of the most detailed wildlife surveys ever conducted. Tiger populations have risen by 6 percent, to roughly 3,000 animals.

Back in 1976, the late Carl Sagan sat down on the Tonight Show with Johnny Carson to talk about a new form of space propulsion called solar sailing. Four decades later, and The Planetary Society has officially demonstrated this "tremendously exciti

The way bats use sound to locate their prey is even more clever than we thought. It turns out that leaf-nosed bats can even find insects that hide themselves from echolocation.

Researchers have developed artificial cells that can respond to external chemical forces, just like real ones do. This exciting step could get us closer to using synthetic biological structures in real-world situations, such as targeted drug delive

The human brain contains a little over 80-odd billion neurons, each joining with other cells to create trillions of connections called synapses.

When Grandma Fish was just a tiny fry, the Titanic was yet to set sail. Humans had yet to reach the South Pole. The First World War wasn't even a rumble on the horizon, the first public radio broadcast yet to spill its arias into New York City.

We all know that Antarctica's ice is melting into the ocean faster than ever, but we haven't had a lot of information on how exactly that ice makes its way across the continent.

Black holes can get pretty big, but there's a special class that is the biggest of the big, absolute yawning monster black holes. And astronomers seem to have identified an absolute specimen, clocking in at 40 billion times the mass of the Sun.

Facebook has removed a mega-viral event called "Storm Area 51", claiming it violated community standards.
