New photos from the James Webb Space Telescope show off the bewitching beauty of the warped quasar RX J1131-1231, which is adorned with four bright spots birthed by mind-bending space-time trickery.

New NASA images of a mountain-size, "planet killer" asteroid that made its closest approach to Earth last month have revealed a surprise companion circling the massive space rock.

New photos of the recently discovered asteroid 2024 MK, which zoomed past Earth in late June, reveal that the massive space rock's orbit has been significantly altered by its close approach to our planet.

The James Webb Space Telescope revealed that the hot Jupiter exoplanet HD 189733 b, located just 64 light-years from Earth, has an atmosphere full of hydrogen sulfide, meaning it likely smells of rotten eggs.

Researchers have discovered a deep-sea hydrothermal vent field near Svalbard in an area previously assumed to be geologically inactive. The newfound vents have been named after various entities from Norse mythology.

Earth from space A 2017 satellite photo captured three hurricanes — Katia, Irma and Jose — in a near-perfect line across "hurricane alley" in the Atlantic Ocean. Interestingly, the storms, which are named alphabetically, appeared to be in the wrong order.

New photos from the European Space Agency's Mars Express orbiter give us our best look yet at a giant ravine on the Red Planet. The dark "scar" was likely birthed by a gigantic blob of magma hidden beneath a massive nearby volcano millions of years ago.

A new paper suggests that we may be able to spot alien spaceships hopping between distant stars using "warp drives" because the sci-fi-inspired technology would give off specific gravitational waves that are unlike anything else we know about.

Astronomers have just discovered two dwarf galaxy candidates orbiting our galaxy. The orientation of these entities suggests there could be up to 500 similar stellar clusters circling the Milky Way, which is more than double previous estimates.

Earth from space This 2018 astronaut photo shows a striking section of the Green River as it winds through Utah's "Labyrinth Canyon." The canyon's steep walls cast long shadows that hide many secrets, including caves and abandoned uranium mines.

The solar system has many more moons than the one we can see in the sky. But how many do we actually know about? And how many more are waiting to be discovered?

Shorty after 4 p.m. ET today (June 27), the mountain-size asteroid 2011 UL21 will come within 5 million miles of Earth, making it one of the largest space rocks to come that close to our planet for 125 years. Here's how to watch the close encounter live, or see it with a telescope.

Experts from NASA and other international organizations recently simulated their response to a hypothetical asteroid impact scenario. The test was deemed a success. However, several media outlets have misreported the group's findings.

Earth from space A 2017 satellite image of the Sahara's Tanezrouft Basin shows the abstract beauty in ancient rock folds and colorful salt flats that have been sculpted in this terrifying region over millions of years.

A new species of piranha-like fish called pacu was recently found hiding in plain sight among several near-identical species in the Amazon River. Researchers have named it after Sauron from "The Lord of the Rings."

A newly identified dinosaur with large, ornate horns on its massive head shield has been named after a famous Norse god who sported a similar headpiece in recent Marvel movies.

Footage shows the record-breaking TOKUFASTbot solving a Rubik's Cube so fast that it appears to happen in a single move. But in reality, advanced AI is helping it rapidly turn the puzzle's colored panels in an imperceptibly fast sequence.

A new analysis of inexplicably young stars orbiting extremely close to the Milky Way's black hole heart reveals that they orbit around the gigantic structure in a surprisingly organized way, similar to swarming insects like bees.

A new study confirms that Earth's inner core has been rotating more slowly than usual since 2010. This mysterious "backtracking" could also end up slightly altering the planet's overall rotation, lengthening our days.

New observations from the James Webb Space Telescope revealed that a distant protostar is actually a pair of baby binary stars that are spitting out parallel energy jets as they gobble up giant disks of gas and dust.

Earth from space This 2018 satellite photo of ice caps on the Arctic islands of Russia's Severnaya Zemlya archipelago highlights the beautiful concentric rings of color in the ice, which stand out against the islands' barren landscape.

Some experts believe that the solar system's hypothetical ninth planet could be just a few years away from being discovered. If this is the case, how long would it take for humans to send probes to the elusive world?

Astronomers have been scouring the outer solar system for signs of a hypothetical ninth planet for almost a decade, without success. However, we may finally be on the cusp of finding it, experts say.

The newly announced Landolt NASA Space Mission will launch a bread box-size "artificial star" satellite that will mimic stars by shining lasers directly at ground-based telescopes. This will enable astronomers to fine-tune instruments and potentially revolutionize how we study the universe.
