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.

Potential Mid-size Black Hole Found

Scientists have found what seems to be an intermediate-mass black hole in a spiral galaxy 100 million light-years away. If its size is confirmed, it could provide much-needed insight into black hole evolution.

Monster Black Hole in Early Universe

Astronomers have discovered one of the brightest quasars in the early universe. The source, SDSS J010013.02+280225.8 (hereafter J0100+2802), is powered by a supermassive black hole at a redshift of 6.3, meaning that its light left it 12.8 billion years ago.

Events during April's lunar eclipse

Solar and Lunar Eclipses in 2015

Two total lunar eclipses occur this year, on April 4th and September 27−28. Meanwhile, a total solar eclipse in March sweeps across remote Arctic waters on March 20th, and a partial event on September 13th is likewise poorly placed for observing. Any list of nature's grandest spectacles would certainly include eclipses of the Sun...

Teacup Galaxy

Tempest in the Teacup Galaxy

New observations of the Teacup Galaxy show that even black holes with wimpy radio jets can quench a galaxy's star formation. An unassuming nearby galaxy nicknamed The Teacup (more formally known as J1430+1339) hides a tempest inside. The supermassive black hole at this galaxy's center is chowing down furiously on gas — seen from...

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...
