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.

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.

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.

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. 🌊

Fact! 

Much of the heat stored inside the planet when it formed has been lost, and the outer crust of Mars is too thick to allow molten rock from below to reach the surface.

Long ago, volcanoes likely played a role in melting ice deposits & releasing floods onto the surface. 💧
