Our universe is home to up to two trillion galaxies, with each galaxy hosting hundreds of billions of stars. That’s…a lot of stars. Each one a ball of fearsome energies, powered by the nuclear fusion of fundamental elements in their hearts. Each one pouring out light into the empty cosmos, illuminating our universe for our wonder and delight.

On Monday, April 5, another first will occur for commercial space flight. For a look back at Crew-1's initial journey to the ISS, catch up on SPACE LAUNCH LIVE streaming now on discovery+.

From the exotic to the just plain odd, our solar system is home to some of the most extreme worlds in the galaxy. But I’m not talking about the planets, I’m talking about their moons. Let’s take a look at the most strange...

One of my favorite things about exoplanet systems is just how weird they can get. It seems that every few months we are treated to another surprise. This time around, NASA's TESS observatory delivered a planet almost three times more massive than Jupiter orbiting around not one, but two stars. As an added bonus: that planet orbits its twin suns closer than the Earth does around the sun. Who wants to take a trip?

Astrophysicist Paul M. Sutter shares the latest in the world of rocket launches and what India’s SSLV is all about.

NASA astronauts Michael Hopkins, Victor Glover, and Shannon Walker, along with Soichi Noguchi of the Japan Aerospace Exploration Agency launched in a new Crew Dragon spacecraft atop a Falcon 9 rocket on November 15, 2020, at 7:27P ET from the NASA Kennedy Launch Complex 39A. After a 27-hour journey, the spacecraft docked with the ISS on November 16, 2020, at 11:01P ET. Let’s see what the astronauts of NASA’s SpaceX Crew-1 mission have been up to since their arrival to the station!

Fans of space are having a tough time picking sides over a recent controversy between SpaceX and astronomers. But what's the big debate all about? Astrophysicist Paul M. Sutter digs into both perspectives.

If Kevin Costner wanted to make a sequel, he’s got plenty of opportunities. Water is by far the most common molecule in the universe. It’s made of two parts hydrogen and one part oxygen. Hydrogen is element number 1 (both on the period table and in abundance), and has been hanging around since the first 15 minutes of the Big Bang. Oxygen is forged in the hearts of sun-like stars, and spreads around when those stars die and turn themselves inside out. And since sun-like stars are also very popular, oxygen gets quite a boost.

After 196 days in space aboard the ISS, NASA astronaut Chris Cassidy, Roscosmos cosmonaut Anatoli Ivanishin, and Roscosmos cosmonaut Ivan Vagner are coming home! Let’s learn the details of their return to Earth.

Below are some exciting space exploration highlights!

Here are a variety of some amazing space launches to look forward to in 2020.

A few years ago, after the successful deployment of the Curiosity rover on Mars, the folks at NASA envisioned a bold new plan to send another mission to the red planet. The mission was scheduled to depart in the then-futuristic year of 2020.

Stargazers rejoice! The annual Perseid meteor shower is upon us. Here's what you need to know...(updated August 11, 2022)

NASA’s new James Webb Space Telescope (JWST) was recently hit by a micrometeoroid. One of the 18 golden mirror segments on the telescope was hit, causing some minor damage.

What, exactly, is a “planet”? For ancient astronomers it was pretty easy. When they stared up at the night sky, they saw a) the sun, b) the moon, c) a lot of fixed stars, d) a few wandering points of light. Those vagabonds were the planets. Indeed, our word planet comes from the Greek word for “wanderer”.
