![]() NASA's Perseverance Rover Wants To Find Mars' Intelligent Life They believed that this crater has some undisturbed layers of ancient rocks, teaching them more about the Red Planet's history. Specifically, NASA's scientists targeted the Gale Crater. He added that brines were the reason why Mars experienced rock resetting. "We used to think that once these layers of clay minerals formed at the bottom of the lake in Gale Crater, they stayed that way, preserving the moment in time they formed for billions of years," added CheMin Principal Investigator Tom Bristow. The component images were taken by the rover's Mast Camera on April 10, 2015.Īlso Read: NASA Astronaut Shows 'Terminator Line' Through Endeavour's Window | Here's How it Looks Like In this handout provided by NASA/JPL-Caltech/MSSS A sweeping panorama combining 33 telephoto images into one Martian vista presents details of several types of terrain visible on Mount Sharp from a location along the route of NASA's Curiosity Mars rover.

NASA's Mars Curiosity Rover discovered that some of the Red Planet's rock records are missing. The component images were taken by the rover's Mast Camera on April 10, 2015.

The scene combines dozens of images taken during January 2015 by the MAHLI camera at the end of the rover's robotic arm. Because it got so big and led to such great things, some people call it the " Big Bang." But maybe a better name would be the " Everywhere Stretch.(Photo : Photo by NASA/JPL-Caltech/MSSS via Getty Images) In this handout provided by NASA/JPL-Caltech/MSSS This self-portrait of NASA's Curiosity Mars rover shows the vehicle at the "Mojave" site, where its drill collected the mission's second taste of Mount Sharp. That’s pretty much how the universe began. ![]() How long did all of this take? Well, we now know that the universe is 13,800,000,000 years old-that’s 13.8 billion. As new stars were being born and dying, then things like asteroids, comets, planets, and black holes formed! At the same time, galaxies were crashing and grouping together. The first stars created bigger atoms and groups of atoms. Over lots of time, atoms came together to form stars and galaxies. As everything expanded and took up more space, it cooled down. When the universe began, it was just hot, tiny particles mixed with light and energy. If things were moving apart, it meant that long ago, everything had been close together.Įverything we can see in our universe today-stars, planets, comets, asteroids-they weren't there at the beginning. This meant that the universe was still expanding, just like Lemaître thought. The farthest galaxies were moving faster than the ones close to us. Just two years later, an astronomer named Edwin Hubble noticed that other galaxies were moving away from us. Thinking about how it all started is hard to imagine. The universe is a very big place, and it’s been around for a very long time. He said the universe stretched and expanded to get as big as it is now, and that it could keep on stretching. He said that a very long time ago, the universe started as just a single point. In 1927, an astronomer named Georges Lemaître had a big idea. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now-and it is still stretching! The big bang is how astronomers explain the way the universe began.
