Last year was a record-breaking one for Operation IceBridge, NASA's aerial survey of the state of polar ice....

A new simulation of supermassive black holes--the behemoths at the centers of galaxies--uses a realistic scenario to predict the light signals emitted in the surrounding gas before the masses collide, said Rochester Inst...

Astronomers have discovered that our nearest large neighbour, the Andromeda galaxy, is roughly the same size as the Milky Way. It had been thought that Andromeda was two to three times the size of the Milky Way, and that...

The Milky Way's neighbouring galaxy, Andromeda, was formed in a colossal crash between two smaller star systems no more than three billion years ago when Earth already existed, researchers said Wednesday.

A star about 100 light years away in the Pisces constellation, GJ 9827, hosts what may be one of the most massive and dense super-Earth planets detected to date according to new research led by Carnegie's Johanna Teske. ...

The shower of electrons bouncing across Earth's magnetosphere, commonly known as the Northern Lights, has been directly observed for the first time by an international team of scientists. While the cause of these colorfu...

Beauty, grace, mystery--this magnificent spiral galaxy has all the qualities of a perfect galactic Valentine. Captured by the NASA/ESA Hubble Space Telescope, the galaxy NGC 3344 presents itself face-on, allowing astrono...

If there is intelligent life out there, it might be broadcasting signals across the universe. Scientists listening out for broadcasts by extra-terrestrials are struggling to get the computer hardware they need, thanks to...

Leonid Kadenyuk, the first astronaut from an independent Ukraine who made his first and only flight aboard space shuttle Columbia in the late 1990s, has died.

The search for Earth-like planets just got a major upgrade: The European Southern Observatory's Very Large Telescope (VLT) in Chile successfully integrated the light from all four of its 8.2-meter (27 feet) unit telescop...

NASA's Solar Dynamics Observatory spacecraft captured gorgeous views of a total solar eclipse on Sunday (Feb. 11), making the mission's birthday even more special.

Two astronauts will venture outside the International Space Station on Friday, Feb. 16, to move components for the station's robotic system into long-term storage. Live coverage of the spacewalk will begin at 5:30 a.m. E...

NASA's Goddard Space Flight Center:

High-resolution observations with the Atacama Large Millimeter/submillimeter Array (ALMA) imaged a rotating dusty gas torus around an active supermassive black hole. The existence of such rotating donuts-shape structures...

In this image from 2009, NASA astronaut Stephanie Wilson is attired in a training version of her shuttle launch and entry suit, as she participates in a training session in the Space Vehicle Mock-up Facility at the Johns...

Astrophysicists at MIPT have developed a model for testing a hypothesis about supermassive black holes at the centers of galaxies. The new model enables scientists to predict how much rotational energy a black hole loses...

Saturn's cratered moon Rhea passes in front of the hazy giant Titan in an image from NASA's Cassini spacecraft, which completed its mission by diving into Saturn in September.

A planet orbiting in the "habitable zone" of its parent star may host a critical ingredient for life as we know it. But what if the habitable zone is unstable? Can life still thrive there?

A cluster of superhot stars glows in the core of the Rosette Nebula in this deep-space image by astrophotographer John Chumack.

SpaceX CEO Elon Musk took to Twitter Monday (Feb. 12) to share some new details on last week's Falcon Heavy test flight, including why the massive rocket's core booster crashed. SpaceX is also building a new droneship fo...
