The Andromeda Galaxy is a giant swirl of around a trillion stars just down the street from the Milky Way. But billions of years from now, it will collide with our home galaxy.

NASA is funding new technologies for building things in outer space, from 3D printed spacecraft parts to habitats grown from fungi.

The Crew-2 mission successfully reached orbit in the early morning hours on Friday, lighting up the Florida sky.

Blue Origin’s spacecraft could ferry nearly 10,000 pounds of cargo and crew to the Moon’s surface — if NASA gives it the green light.

From stars made of dark matter to stars literally living inside their partners, these stellar systems are theoretically possible.

The ancient Egyptians watched Earth’s night sky closely and named constellations after their gods. But did the builders of the pyramids really make these monuments with the stars in mind?

Engineers hid the phrase “Dare Mighty Things″ on the parachute of NASA’s Mars Perseverance rover. It isn’t the first time they’ve snuck a fun surprise or a sentimental object onto a spacecraft, either.

The “Skycrane” maneuver that will soon place Perseverance on Mars’ surface was once considered a crazy idea — even within NASA.

Ancient civilizations used the powerful waterway for trade, agriculture and building projects. In turn, it fueled historic societal growth.

Pyramid workers were paid locals. Yet historical narratives and Hollywood films have made many believe the Jews built the pyramids while enslaved in Egypt.

Magnetars are the most magnetic objects in the universe, and they should be relatively common. Yet, astronomers have had a hard time studying them.

NASA may finally be serious about the idea of building a large radio telescope in a lunar crater.

Fake Aztec crystal skulls are found in museum collections around the world. They can all be traced back to one man.

These pyramids in Peru are older than the ones in Egypt, and predate the Incan Empire by roughly 4,000 years.

Parallel universes could exist, whether cosmologists can prove it or not.

This year, SpaceX launched the first privately owned capsule carrying NASA astronauts to the space station and back. NASA, as well as private companies, also made giant leaps for space travel in 2020.

Many archaeologists have hunted for evidence to support or refute the ancient Biblical stories about Israel. But the First Temple in Jerusalem — and its builder, King Solomon — remain shrouded in mystery.

NASA and SpaceX’s Crew-1 mission successfully launched to the International Space Station on Sunday, carrying four astronauts on the first “operational mission” using a Crew Dragon spacecraft.

We may never know.

Ecologists can now forecast bird migrations like meteorologists forecast the weather. But without on-the-ground citizen science observations, it’s hard to tell a songbird from a goose.
