Astronomers Discover Second-Closest Known Exoplanet

The planet, a frozen Super-Earth, orbits Bernard's Star about six light-years away

Water found deep within the planet's interior contains different ratio of heavy hydrogen isotopes and normal hydrogen, pointing toward separate point of origin

Where Did Earth’s Water Originate? Solar Nebula, Study Suggests

Researchers say the hydrogen contained in these clouds of gas and dust contributed to formation of one out of every 100 water molecules found on Earth

A silica sphere with a radius of 50 nanometers is trapped levitating in a beam of light.

Optical Tweezers Give Scientists a Tool to Test the Laws of Quantum Mechanics

Quantum superposition is one of the great mysteries of physics—a mass existing in two states at once—and scientists hope to probe the phenomenon

The Milky Way

The Milky Way Ate One of Its Neighbors 10 Billion Years Ago

Star data shows we gobbled up a galaxy called Gaia-Enceladus about 1/4 the size of the Milky Way, leaving behind telltale signs of the merger

Launched in 2009, Kepler discovered thousands of new exoplanets before finally running out of fuel earlier this month

Well then what would we call a cow that jumps over a moonmoon?

If a Moon Has a Moon, Is Its Moon Called a Moonmoon?

A new study suggests it's possible some moons could have moons and the internet wants to give them a name—but scientists have yet to actually find one

Saturn's Rings Rain Organic Compounds Into Its Atmosphere

The Cassini probe's final flybys show that 22,000 pounds of material per second drops from the rings into the planet's ionosphere

Astronomers Find What May Be First Exomoon—And It's an Absolute Unit

Astronomers suspect that there's Neptune-sized celestial body trailing an exoplanet about 8,000 light years

The Green Bank Telescope pictured—and other radio telescopes like it—are listening for "technosignatures," or possible transmissions from intelligent life forms

In the Search for Aliens, We've Only Analyzed a Small Pool in the Cosmic Ocean

A new study estimates how much of outer space we've scoured for other life and finds we haven't exactly taken a deep dive

TESS Space Telescope Will Find Thousands of Planets, but Astronomers Seek a Select Few

NASA's new space telescope has already discovered two planets, but the hunt for a world like Earth is just getting started

The Universe's Strongest Material is a Cosmic Lasagna

A new study suggests that the "nuclear pasta" found in neutron stars is 10 billion times stronger than steel

This Pulsar is Giving Off Weird Infrared Light and We're Not Sure Why

Researchers believe a disk of dust from a supernova or a pulsar wind nebula could explain the strange energy signal

'It Wasn't Aliens': Solar Observatory That Was Mysteriously Evacuated Will Reopen Tomorrow

The Sunspot Observatory in New Mexico was closed for ten days due to a 'security threat,' though aliens and solar flares have been ruled out

Jocelyn Bell Burnell photographed in 2011

Decades After Being Passed Over for a Nobel, Jocelyn Bell Burnell Gets Her Due

Honored with a Special Breakthrough Prize, the astrophysicist says she'll use the winnings to fund scholarships to support today's outsiders in the field

Artist's impression of galactic wind.

Astronomers Spot Galactic Wind From Early Universe

The ejection of molecular gas from a galaxy 12 billion light-years away may have kept an early galaxy from burning out too quickly

Monster Galaxy Churns Out 1,000 Times As Many Stars As Our Own

COSMOS-AzTEC-1 is almost 13 billion years old highly organized but unstable and could shed light on galaxy evolution

Astronomers Say This Reflective Space Sculpture Will Cause Unneeded Light Pollution. The Artist Argues Otherwise

‘Orbital Reflector,’ a 100-foot long, diamond-shaped balloon, aims to inspire humans to gaze up at the night sky with a renewed sense of wonder

Why Astronomers Want to Look for Earth's Mini-Moons

A new, powerful telescope in Chile will be able to detect tiny asteroid chunks circling our planet, which could be a goldmine for researchers

Andromeda

The Andromeda Galaxy Ate The Milky Way's Lost Sibling

New simulations show Andromeda absorbed the large galaxy M32p about 2 billion years ago
