The orbiting laboratory travels 5 miles per second, traveling around our planet every 90 minutes.

This is a composite long exposure image from the International Space Station. NASA astronaut Don Pettit combined multiple 30-second exposures from a mounted camera on the space station into one image.

The axis of the Earth is now increasing its tilt relative to the Sun, warming the hemisphere significantly. This causes new plant growth to “spring forth,” giving the season its name.

Happy #FirstDayofSpring! Today is the day of the vernal equinox, also known as the spring equinox, marking the change of the season in the Northern Hemisphere. https://t.co/6A2zFGV4qW

We have our champion. 

Matter, compressed and then smashed together by supermassive black holes, creates the most intense and energetic event in the universe.

When galaxies collide, they can create tremendous starbursts. 

As gas follows that collision, shockwaves are formed, and a new generation of stars are born into the galaxy.

Galaxies look calm and serene, but they can get into pretty big scraps. 🤺

When two galaxies try to merge, their gravity pulls on each other, twisting and distorting their structures. 

This cosmic tango brings two supermassive black holes together.

What starts the process of creating a supermassive black hole? A giant star. 

These stars don't live for long. When they die, they flame out in a huge explosion, creating a supernova.

In the universe's heavy weight championship, there's an ongoing fight between two supermassive black holes. Who will win in the fight of the cosmos? 🥊

For the first time, direct geological evidence of recent volcanic activity has been observed on the surface of Venus. Scientists made the discovery after poring over archival radar images of Venus taken more than 30 years ago by NASA’s Magellan mission.

Spinning dead stars, called pulsars, are used to measure the gravitational waves from super massive black holes.

The army of robotic explorers continues to rewrite the story of the Red Planet. 🦾

They've discovered a once warm, wet world with the potential for life.

A volcanically active Mars suggests that its interior may still be warm. 

The Insight rover's layout of Mars reveals a 969 mile deep mantel, surrounding a metal rich core. 🪨

The sun deploys a constant stream of particles called the Solar Wind. 

The wind is over 1 million degrees Fahrenheit, and travels up to 500 miles a second.

When it reaches Mars, it strips away gases high up in the atmosphere.

The Curiosity rover has taught us a lot about the history of Mars and its potential to support life.

Evidence shows that about 3 billion years ago, its landing site, Gale Crater, was a lake fed by rivers.

February 2021: the newest robot investigator speeds toward Mars. ☄️ 

The most advanced robot NASA has ever sent to another world, its job is to seek signs of ancient life and collect samples of rock and regolith.

This is Perseverance. https://t.co/nyCccUAcT9
