SpaceX launched four private citizens to space on Wednesday, September 15, at 8:02PM ET. Following their three-day trip around the Earth, the SpaceX Crew Dragon capsule successfully splashed down off the coast of Florida Saturday evening. There were no professional astronauts aboard the Crew Dragon spacecraft. Let’s learn more about Inspiration4's journey. Updated Monday, September 20.

Black holes are tricky creatures. Since ancient times the practice of astronomy has been to point our eyes and instruments at all the glowing things in the skies above us. But black holes are defined by the fact that nothing, not even light, can escape their gravitational clutches. So how you do see something that is completely, totally black?

After a harrowing landing and traveling nearly 292.5 million miles, NASA's Perseverance with Ingenuity touched down on Mars at 3:55P ET today, February 18, 2021.Congratulations to the teams at NASA and JPL. We cannot wait to see what research comes from this incredible mission.Experience more Mars on discovery+.

Space hotels may be in our future.

Sure, the Sun is big. It’s over a hundred times wider than the Earth and weighs over 330,000 times the mass of our planet.It’s peanuts.

If you've seen a shooting star on a recent stargazing jaunt, you've spotted the very beginning of the Orionids meteor shower. It happens every fall in October or early November, and peak viewing hours are coming soon to skies near you.

After the NASA/SpaceX launch experienced a series of delays, Crew-3 is set to lift off no earlier than 9:03 P ET from NASA's Kennedy Space Center tomorrow!Watch SPACE LAUNCH LIVE: CREW-3 LIFT OFF on Science Channel at 8 P ET Wednesday, November 10.

This morning, on July 20, 2021, Blue Origin's first crewed spaceflight was a success! Congrats to Blue Origin founder Jeff Bezos and three crewmates, who lifted off into space from Blue Origin’s Launch Site near Van Horn, Texas. Here's the play-by-play of the New Shepard's approximitely 10 minute flight from launch to capsule landing, which looked picture perfect.

Whether it’s less severe than other variants or not, we can all agree that the Omicron variant of the coronavirus is no fun at all. But despite its ominous name, “omicron” is just the 15th letter of the Greek alphabet. In astronomy, the stars in any constellation are ordered from brightest to dimmest, with the brightest getting the name “alpha”, the second brightest “beta”, and so on. And believe it or not, there are some pretty cool omicrons out there.

The United States Space Force may have a somewhat silly name, but it's very, very real. And it just launched a semi-secret mission into space.

How do you see a perfectly black object in the middle of a pitch-dark night? It sounds like the start of an annoying riddle, but it’s really the question faced by astronomers when they want to search for black holes.

Jupiter is the OG best friend in the solar system. It finds all the tiny little comets and asteroids heading for the vulnerable inner planets and takes one for the team, chewing up the dangerous rocks in its thick atmosphere. It happened again just recently, and this time an amateur astronomer caught it in the act.

The fourth largest piece of space debris ever re-entered the earth's atmosphere yesterday and made a splash just off the coast of Africa. Narrowly missing some major landmarks in its path, this piece of a rocket could have caused some major damage.

Axiom Mission 1 blasted off from NASA's Kennedy Space Center today, setting the standard for commercial space travel with a first-of-its-kind mission to the International Space Station (ISS).

Learn about how astronomers may have just discovered the first moon beyond our solar system; why the “jacuzzi of despair” kills everything that enters it; and why the winner effect says one win leads to even more wins.
