Meet the Global Team That Captured the First Image of a Black Hole

Never before had scientists seen the phenomenon until they rallied colleagues around the world to view a galaxy far, far away

To Find Baby Planets, Researchers Chase Waterfalls of Gas

Analysis of data from the ALMA telescope shows gas flows from the surface to middle of protoplanetary discs as new planets form

Based on the speed and trajectory of a newly detected object, astronomers believe it came to our solar system from beyond. This illustration shows the first known interstellar object to fly though our solar system, 'Oumuamua.

Astronomers Spot a Comet That Likely Came From a Different Solar System

After 'Oumuamua, the newly detected rock is just the second known object to visit from interstellar space

First Moon-Forming Disk Detected Swirling Around an Exoplanet

Telescope observations suggest that a cloud of gas and dust around a planet 370 light-years away may be coalescing into planet-sized moons

The image reveals the black hole at the center of Messier 87, a massive galaxy in the nearby Virgo galaxy cluster. This black hole resides 55 million light-years from Earth and has a mass 6.5 billion times that of the sun.

If Light Can't Escape Black Holes, How Do We Get Photos of Them... and More Questions From Our Readers

You asked, we answered

Jupiter Officially Has 12 New Moons

The new satellites are mostly tiny and include one oddball that is on a collision course with some of the 78 other moons orbiting the planet

China's Tiangong-1 Finally Crashes Back to Earth

Most of the craft likely burned up as it re-entered the Earth’s atmosphere

Marvin, a trailblazer in more ways than one, surveys the Antarctic terrain on her meteorite-hunting expedition of 1978-79.

The Rockstar Geologist Who Mapped the Minerals of the Cosmos

A professor told Ursula Marvin she should learn to cook. Instead she chased down meteorites in Antarctica

Nicknamed the Hand of God, this pulsar wind nebula is powered by a pulsar: the leftover, dense core of a star that blew up in a supernova explosion. Before astronomers had any idea what they were, Jocelyn Bell Burnell found the signal of a pulsar in her telescope data in 1967.

Fifty Years Ago, a Grad Student’s Discovery Changed the Course of Astrophysics

By identifying the first pulsars, Jocelyn Bell Burnell set the stage for discoveries in black holes and gravitational waves

Jupiter's Auroras Are Surprisingly Out of Sync

X-ray bursts from the poles are expected to line up, but the south is regular while the north produces haphazard bursts

Could a Magnetic Shield Protect Earth From Space Weather?

A bad geomagnetic storm would fry the electric grid and cripple civilization for years—a space shield is cheap by comparison

Your eclipse glasses won't be the only tool to make this month's stellar phenomenon cool

Use This App to Get the Most From the Coming Eclipse

With livestreams, simulations and safety guides, this Solar Eclipse app will be the key tool for the upcoming astronomical extravaganza

An artist's rendering of a star colliding with the surface of a supermassive sphere. In recent years some scientists have surmised that black holes may be hard objects rather than a region of intense gravity and compressed matter.

Could You Crash Into a Black Hole?

Probably not, but it’s fun to think about

Exoplanet Discovery Arrives in Time for New Telescope Technology

Astronomers call LHS 1140b one of the "best targets" for hunting liquid water with NASA's James Webb Space Telescope

Shortly after the announcement of the TRAPPIST-1 system, NASA crowdsourced its Twitter followers for possible planet names. The actual process of naming new planets, however, is a bit more involved.

How Do New Planets Get Their Names?

Sorry, Planet McPlanetface: Asteroids, moons and other celestial bodies go through a strict set of international naming guidelines

The seven Earth-sized planets orbiting the dwarf star TRAPPIST-1.

Scientists Spot Seven Earth-Sized Planets Orbiting a Nearby Star

This newly discovered solar system presents the best opportunity yet to study potentially habitable worlds, NASA scientists report

An infrared image of 47 Tucanae, a dense globular cluster of stars located roughly 16,000 light years from Earth. A new study has predicted that a black hole lies at its center.

How Astrophysicists Found a Black Hole Where No One Else Could

A new method could help scientists peer inside universe's densest star clusters to find undiscovered black holes
