Galaxy cluster creates ‘magnifying glass’ in space
A massive galaxy’s gravity is so strong that it bends light, creating a “lens” in space. This natural magnifying glass is giving astronomers a rare view of a supernova on the other side of the universe.

Black holes are on collision course
But be patient. The distant galactic smashup is still some million years away.

Picture This: Falling to a comet
After a more than decade-long ride, a robotic lander has left its spacecraft and floated down onto the surface of a comet. From there it should begin scouting for hints at how our solar system formed.

Explainer: Understanding ice ages
Earth slowly wobbles, tilts and stretches (or contracts) as it orbits the sun. These changes may be fairly small and subtle. Still, their cumulative impacts can be huge — sometimes triggering the slow onset of an ice age or an abrupt thaw.

Explainer: What are asteroids?
Leftovers from the creation of the solar system, asteroids are space rocks that orbit the sun. Let’s hope the big ones never become meteorites.

Monster collision in space
The smashup of four clusters of galaxies has sent a super-hot jet of charged particles spewing 2.5 million light-years into space!

First mega-Earth found
Astronomers are puzzled by Kepler-10c. This exoplanet is rocky like Earth — but as massive as Neptune. And that challenges their accepted ideas about how planets form.

Sun sibling spotted
Separated at birth: Astronomers find a star 110 light-years away. It was born at the same time as our sun and from the same cloud of gas and dust.

Distant planet may boast the longest year
On a planet far, far away, a single pass around its sun may seem to last forever.

Heavenly research
Groundbreaking research in astronomy landed four high school seniors spots as finalists in the 2014 Intel Science Talent Search.

Surprising rings circle comet-asteroid hybrid
It’s too small to be a planet. Yet this planet wannabe still resembles Saturn-like giants. It’s the smallest solar system inhabitant to, like them, host rings of orbiting ice.

Distant galaxy plows through cluster of others, with baby stars in tow
