Scientists have obtained the first image of a black hole, using Event Horizon Telescope observations of the center of the galaxy M87. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun. This long-sought image provides the strongest evidence to date for the existence of supermassive black holes and opens a new window onto the study of black holes, their event horizons, and gravity.

Scientists just released the first-ever photograph of a black hole. Some people think it looks like a ‘smudge on the lens.’

Scientists from 40 nations who worked for around 13 years to get the first-ever image of a black hole, which is larger than our solar system.
The first image of a black hole. The picture was made using Event Horizon Telescope radio-wave observations of the center of the galaxy M87.

The first-ever picture of a black hole is fuzzy. These incredible illustrations help explain what it shows.

Scientists posted the first-ever image of black hole, but the photo is a bit fuzzy. However, computer models hint at what we'd see with a better view.
Asteroid 6478 Gault with two narrow, comet-like tails of debris that suggest the space rock is self-destructing.

The Hubble telescope spotted an asteroid that has grown two tails — and scientists think it’s ripping itself to pieces

A 2.5-mile-wide asteroid called Gault was discovered in 1988, but it may not exist as we know it for much longer. The space rock is spinning apart.

An experiment that solved a 100-year-old mystery posed by Einstein is about to turn back on — and it’s more powerful than ever

On Monday, a game-changing pair of gravitational-wave detectors called LIGO will turn back on after 6 months of downtime and upgrades.

The first day of spring is finally here — for about 90% of us. Here’s why equinoxes mark the changing of seasons.

The spring or vernal equinox happens at 5:58 p.m. ET on Wednesday, March 20, 2019. Here's how Earth and the sun work together to change our seasons.
A jet flies in front of February's supermoon, also called a "super snow moon."

Tonight’s ‘super snow moon’ will be the biggest and one of the brightest full moons of 2019. Here’s why.

February's full moon, also called a "snow moon," will be the biggest of 2019. That's because it's a perigean moon, or "supermoon," close to Earth.
Sirius is a binary star system and the brightest object that stargazers can see in the night sky from Earth.

An asteroid will block the sky’s brightest star tonight, and astronomers need your help seeing it

Sirius is the brightest night-sky object, but for a moment on President's Day, asteroid Jürgenstock will occult the star system and dim its light.
A picture of Neptune taken by the Voyager 2 spacecraft, showing a since-vanished dark storm.

The Hubble telescope has discovered a ‘dark vortex’ raging on Neptune that would swallow 20% of Earth’s surface

New pictures taken by the Hubble Space Telescope reveal a mysterious "dark tempest" storm raging on Neptune and a "giant" frigid cap on top of Uranus.
An illustration of the space object 'Oumuamua flying through the solar system in late 2017.

A bizarre interstellar object called ‘Oumuamua continues to perplex astronomers a year after it vanished. Here’s why a few scientists stil...

'Oumuamua remains a mystery since its discovery. However, the idea that it's extraterrestrial is based on a lack of data, not extraordinary evidence.
The newfound planet K2-288Bb, illustrated here, is slightly smaller than Neptune.

Scientists have discovered a new planet twice the size of Earth, and it could have liquid water on its surface

Scientists have discovered a new planet that's 226 light-years away. It is roughly twice the size of Earth, which is rare for an exoplanet.
