A timeline of the Space Race and early human spaceflight

Evidence of the Big Bang theory and what happened immediately after the explosion.

There are three theories as to how the Moon could have been created.

Black holes are extremely compact cosmic objects so massive that not even light can escape their gravity.

NASA’s Perseverance rover launched on July 30, 2020 and plans to touch down on Mars on February 18, 2021. NASA raised awareness for this mission by a Send Your Name to Mars campaign where almost 11 million names were submitted and put on a microchip aboard Perseverance.

Finding a science gift for adult astronomers can be tricky, but the Space & Beyond Box is the perfect gift for adults who can’t get their heads out of the stars.

As the moons of the solar system were discovered, astronomers became desperate to learn more about these strange natural satellites.

Our solar system is a really weird place, and here are just a few of the reasons why.

Learning to observe the night sky is intimidating. But with this beginner’s guide to observing, you’ll be navigating the night sky like a pro in no time.

If you fell into a black hole, your body would be ripped apart through “spaghettification.” But exactly how depends on what type of black hole you fell into.

Some black holes are born when a dying star collapses in on itself. Others through mergers. And some may have started off in an even weirder way.
