If an asteroid really threatened the Earth, what would a planetary defense mission look like?

By Meghan Bartels

Someday, tucked away gathering dust in a nondescript warehouse, there will perhaps be a spacecraft waiting to be called to the launch pad, even as its builders pray it never flies.

The hypothesis could help to explain the weird discrepancies spotted in space-time ripples from enormous black hole collisions.

The interloper 'Oumuamua continues to puzzle astronomers and astrophysicists.

Interstellar visitor 'Oumuamua wasn't a nitrogen iceberg, Harvard astrophysicists say

By Kimberly Hickok

The interstellar visitor 'Oumuamua might not be a nitrogen iceberg after all. But what is it?

Researchers at Rochester’s Laboratory for Laser Energetics used the same set-up at the recent study to create superionic ice, shown here in this artistic rendering. In that instance, the ice was not stable.

Ultrahot 'superionic' ice is a new state of matter

By Ben Turner

To create the ice, the scientists had to squeeze a water droplet to 3.5 million times Earth's atmospheric pressure and heat it hotter than the sun.

Wormholes may be viable shortcuts through space-time after all, new study suggests

By Paul Sutter

Wormholes may be stable after all, a new theory suggests, contradicting previous predictions that these hypothetical shortcuts through space-time would instantly collapse.

The number of satellites orbiting the Earth is increasing exponentially.

How many satellites orbit Earth?

By Harry Baker

The number of satellites orbiting Earth is skyrocketing, and this may be causing more problems than solutions in the long term.

Comet 67P, the famous target of the Rosetta mission, has made its closest approach to Earth in November 2021.

Rosetta's 'rubber ducky' comet makes closest approach to Earth, will disappear for 200 years

By Tereza Pultarova

Comet 67P, which famously hosted the first-ever cometary lander in 2014, made its closest approach to Earth on Friday (Nov. 12).

A new NASA video highlights the giant ozone hole that opened over the Antarctic this year.

A sequined sea turtle floats above Crew-3 astronaut Kayla Barron's head aboard the SpaceX Dragon spacecraft "Endurance." The doll served as the mission's "zero-g indicator" and signaled the flight of the first members of "The Turtles" in space.

Outside of Earth's 'shell,' SpaceX's Crew-3 reveal turtle as zero-g indicator

By Robert Z. Pearlman

Just moments after entering Earth orbit, SpaceX Crew-3 astronaut Kayla Barron released a sparkling sea turtle to float above her head. The "zero-g indicator" showed she and her crew were weightless.

Wormholes are still the stuff of science fiction.

What are wormholes?

By Paul Sutter

Wormholes connect two points in space and time and are a staple of science fiction. But are they possible in the real universe?
