Kerbal Space Program is one of my favorite games!

"This is now becoming so real."

The Euclid telescope, just launched today, will be able to observe galaxies out to 10 billion light-years. Here's the largest map I could find (1 billion light years) that includes the Milky Way, Laniakea, the Shapley supercluster, the Perseus–Pisces supercluster, and the South Pole Wall....

White holes are mathematically possible, according to general relativity. But does that mean they're actually out there?

I would choose Mars, mostly because of all the plans that we have for it. Imagine having people actually living there, it sounds insane!

Let’s not send a few thousand people to Mars as a big experiment in survival....

The first world that humans should inhabit beyond the Earth is the Moon, not Mars. Here's how to terraform our lunar neighbor.

NASA's Webb telescope spotted an active supermassive black hole that existed 570 million years after the Big Bang. That's really early.

Apollo 11 was the American spaceflight that first landed humans on the Moon. Commander Neil Armstrong and lunar module pilot Buzz Aldrin landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC, and Armstrong became the first person to step onto the Moon's surface six hours and 39 minutes later, on July 21 at 02:56...

It's a destructive setback with potential ramifications for the company's customer United Launch Alliance as well as Blue Origin's own rocket New Glenn....

A study published this week in an astronomical journal suggests our universe could be 26.7 billion years old, or about twice as old as we thought.

Using nuclear fusion, Pulsar's rocket could dramatically increase travel speeds, aiming for tests by 2025 and fusion temperatures by 2027.

When NASA crashed its DART spacecraft into the asteroid Dimorphos, the goal was to shorten the space rock's orbit around its parent asteroid. The mission succeeded - but Dimorphos' orbit has continued to shrink and it isn't clear why

There's a lot of trash on the moon right now—including nearly 100 bags of human waste—and with countries around the globe traveling to the moon, there's going to be a lot more, both on the lunar surface and in Earth's orbit.

Russia’s Luna-25 mission ended in failure after crashing into the moon, space agency Roscosmos has announced.

India has launched its Chandrayaan-3 mission, which aims to explore the south pole of the moon by rover, completing a scientific mission that was first attempted in 2019 but ended in catastrophic failure due to a software glitch...

NASA's Juno spacecraft, which has been probing Jupiter since 2016, captured the moment lightning crackled in the gas giant's stormy atmosphere at its north pole.

How humanity responds to the first contact with intelligent alien life could determine the very fate of our species.

We have no explanations for this sort of slow repeat.

Watch the European satellite, called Euclid, soar to space aboard a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station on Florida's Space Coast. The launch took place today, July 1, at 11:11 a.m EDT.

Astronauts aboard the International Space Station have achieved a 98% water recovery rate in a breakthrough achieved by a method that might make the faint of heart slightly squeamish: they hit peak astronaut pee recycling....
