News

From mysteriously quiet solar cycles to the evidence for Big Bang inflation, important stuff happens in astronomy. When it does, you can depend on Sky & Telescope’s editors and bloggers to keep you up to speed. We pride ourselves on our accurate, in-depth reporting of current astronomy news — instead of sound bites, we want to give you what you need to really understand the latest space events, whether they be observations from orbiters around Mars or the discovery of what’s to blame for powerful cosmic explosions. We talk to the experts, and then we talk to you.

So if you’re looking for responsible science journalism, look no further: here you’ll find the facts behind the headlines.

BICEP’s Big Bang Finding Reduced to Dust

Yes, it was too good to be true. The cosmic "discovery of the century" last March has officially blown up. Or will blow up next week when a new analysis of polarization in the cosmic microwave background is officially released. The excitement burst onto the world 10 months ago when the BICEP microwave background...

Rosetta Reveals Much About Comet 67P

Once the Rosetta spacecraft arrived at Comet 67P/Churyumov-Gerasimenko last August, European scientists used an array of instruments to assess every nook and cranny of the remarkable two-lobed nucleus.

This artist's conception shows the inner four planets of the Gliese 581 system and their host star, a red dwarf star only 20 light years away from Earth. The large planet in the foreground is the newly discovered GJ 581g, which has a 37-day orbit right in the middle of the star's habitable zone and is only three to four times the mass of Earth, with a diameter 1.2 to 1.4 times that of Earth.

Do Atmospheres Spin Worlds to Habitability?

The best place to look for nearby Earth-size planets are around the smallest, coolest stars. New research shows that any exoplanets tightly circling their stars might have a better chance of being habitable than previously thought.
