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.

The Quasar Main Sequence

A new diagram might link the diverse visible-light characteristics of quasars to two physical properties — essentially, their accretion rate and orientation. If the analysis holds up, it could point the way toward a long-sought unification.

Star before and after adaptive optics

Next-Gen Adaptive Optics

The Subaru Telescope has donned a new pair of glasses called Raven, a multi-object adaptive optics system that enables astronomers to correct for atmospheric turbulence over an unprecedented field of view.

A Worldwide Night of Moonwatching

International Observe the Moon Night is an event that encourages people to "look up" and enjoy our nearest neighbor. This year's InOMN is Saturday, September 6th. Here's a quiz: What astronomical object looks amazing no matter what the magnification, never looks exactly the same no matter how often you view it, and can be...

Laniakea: Our Home Supercluster

Astronomers have mapped the cosmic watershed and discovered a massive supercluster that extends more than 500 million light-years and contains 100,000 large galaxies. The Milky Way sits on the edge of this humongous structure.

Tour September’s Sky: Farewell to Saturn

The astronomical calendar says autumn arrives on September 22nd. It's a season of transition, with plenty of celestial comings and goings in the evening sky. September’s equinox takes place on the 22nd at 10:29 p.m. Eastern Daylight Time. At that moment the Sun shines directly overhead as seen from the equator. Days and nights...

Pleiades

Resolving the Pleiades Distance Problem

A new measurement, made using radio interferometry, argues that the distance to the Pleiades star cluster measured by ESA's Hipparcos satellite really is wrong — and that ground-based astronomers had it right all along.

Crescent cradles the 'old moon'

Earthshine, the Moon’s Darker Side

With a subtle beauty all its own, the earthshine we see glowing in the lunar night invites us to consider Earth's many connections to the Moon This week's crescent Moon offers more than two horns to hang your hat on. Take a close look, and you'll see an entire circle of moonlight. Sunlight illuminates...
