The Hubble Space Telescope orbiting Earth in May 2009.

‘No image will surpass this’: Hubble telescope astronomers created a stunning picture of the deep universe with 16 years’ worth of p...

Researchers estimate the Hubble Space Telescope image includes 265,000 galaxies, some of which appear as they existed 13.3 billion years ago.
An occultation of Saturn and the moon, as seen from South Africa on March 29, 2019, using a smartphone mounted to a telescope.

A photographer recorded Saturn ‘touching’ the moon with his smartphone, and the pictures are stunning

Grant Petersen of South Africa spent months preparing to photograph the conjunction of the moon and Saturn using a Galaxy S8 phone and a telescope.
A computer simulation of how a supermassive black hole.

The first ‘groundbreaking’ pictures of a black hole may be unveiled on Wednesday. Here’s what scientists think those images will loo...

Scientists are expected to unveil the first-ever pictures of a black hole's "shadow" caused by its event horizon.
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.
Russell "Rusty" Schweickart, a retired NASA astronaut, speaks at an event in July 2006.

Astronaut says a neglected telescope is NASA’s best chance of defending Earth from ‘city killer’ asteroids — ‘for God...

Astronaut Rusty Schweickart says the Near-Earth Object Camera telescope could locate most of the dangerous space rocks that NASA is mandated to find.
An illustration of the exoplanet candidate Barnard's star b, also known as GJ 699 b.

Astronomers found a ‘cold super-Earth’ less than 6 light-years away — and it may be the first rocky planet we’ll photograph be...

Astronomers think they've found a "cold super-Earth." It might be the first exoplanet they photograph with a coming generation of powerful telescopes.
An illustration of NASA's Kepler space telescope.

NASA’s planet-hunting Kepler telescope is dead 9 years after launching into space

The Kepler space telescope was launched in 2009 and has stared down more than 500,000 stars. But NASA says Kepler has run out of fuel.

NASA came up with 21 new constellations — including Albert Einstein, Godzilla, and the Starship Enterprise

The gamma-ray sky was invisible to humans until instruments like NASA's Fermi space telescope came along. That observatory has been mapping a previously unseen universe for a decade, so in honor of that milestone, scientists on the mission suggested 21 modern (and entertaining) constellations.
The Hubble Space Telescope orbiting Earth in 2009.

NASA’s Hubble space telescope just lost a vital part, and one of its backups is ‘acting drunk.’ Here’s why astronomers haven&#...

A vital part of the Hubble Space Telescope, which records stunning images of the universe, failed on Friday. The part is one of six gyroscopes that help the observatory stay pointed at celestial objects. Three others still work, but NASA may start using just one, limiting Hubble's observations.
A thick ring of space junk orbits Earth in this fanciful artist's concept of a "Kessler syndrome" event.

The International Space Station sprang a leak yesterday — and it shows why a space junk disaster could cut off human access to space

The International Space Station briefly sprang a small leak, but NASA says the six-person crew in orbit is safe. A tiny piece of space trash may have caused the leak. Experts worry that a large hit could lead to a "Kessler syndrome" event that cuts off human access to space.
