    Earth has craters just like the Moon! Here is what NASA says

    1/5 Other than the Moon and our Solar System, Earth too has been hit by several asteroids and other objects creating craters on its surface. But it needs to be noted that not every object heading towards Earth reaches its ground mainly because of the atmospheric layers. Here are some of the biggest craters impact that dented the surface of the Earth. (Google Earth)
    Asteroid and Earth
    2/5 What is an impact crater? According to the information provided by Space Place, NASA, "An impact crater is formed when an object like an asteroid or meteorite crashes into the surface of a larger solid object like a planet or a moon. To form a true impact crater, this object needs to be traveling extremely fast—many thousands of miles per hour! When a solid object crashes into something at these super fast speeds, it forms a crater regardless of how hard or tough it is." (Pixabay)
    Crater on Earth
    3/5 Evidence of really big impacts – such as Arizona’s Meteor Crater – is harder to find on Earth. The impact history of our home world has largely been erased by weather and water or buried under lava, rock, or ice. Nonetheless, we still find new giant craters occasionally, NASA said. In 2019, a NASA glaciologist discovered a possible impact crater buried under more than a mile of ice in northwest Greenland. That followed the finding, announced in November 2018, of a 19-mile-wide crater beneath Hiawatha Glacier – the first meteorite impact crater ever discovered under Earth’s ice sheets. Though these impact sites in northwest Greenland are only 114 miles apart, at present they do not appear to have formed at the same time. (Pixabay)

    4/5 Meteor Crater (also known as Barringer Crater) in Arizona was the first crater discovered to be formed by an extraterrestrial impact. It formed 50,000 years ago from a meteorite that may have been up to about 150 feet wide traveling more than 28,000 mph, according to the information provided by NASA.

    5/5 Vredefort crater in South Africa is the largest known impact crater on Earth—almost 200 miles across. At over 2 billion years old, it is also one of the oldest. Because of erosion over this long time period, the crater is a bit difficult to see. (NASA)

    Do you want to track Earth's vital signs and find out if it is doing all right or if it is in danger? You can do so now through this NASA tool. In fact, everything from carbon dioxide and carbon monoxide to sea level and soil moisture levels, and more can be checked. You can do it all with the help of 3D real-time visualization tool. NASA's real-time 3D visualization tool Eyes on the Earth also got an upgrade to include more datasets. Informing about the same Jet Propulsion Laboratory (JPL), NASA said, "NASA's real-time 3D visualization tool Eyes on the Earth got a recent upgrade to include more datasets, putting the world at your fingertips. Using the tool, you can track the planet's vital signs – everything from carbon dioxide and carbon monoxide to sea level and soil moisture levels – as well as follow the fleet of Earth satellites providing those measurements."

    Using the tool you will be able to learn more about environmental phenomena and their impact. "For instance, to see measurements of the greenhouse gas carbon dioxide in a particular part of the globe, navigate to the Vital Signs menu and click the carbon dioxide button. Eyes on the Earth will show a visualization of data from NASA's Orbiting Carbon Observatory 2 (OCO-2) satellite, which measures the gas from the ground to the top of the atmosphere. Click “animate data,” specify a date range and see how levels shift over time," the report by JPL said.

    It can be known that there are eight vital signs to choose from, with background information on the role each plays. The Eyes on the Earth also provides snapshots of significant events in the natural world. For instance, you can see details about the maximum wind speeds of a tropical storm, the impacts of a northern California fire, even see the scale of a phytoplankton bloom off of New Zealand and why it matters.

    The report further added, "the graphics are as rich as the data, making for fascinating deep dives as you learn about the science, get to know the planet better, and learn about some of the many NASA missions that track the globe's health. And while no downloads are required, the web-based application makes a great addition to any device with a browser and an internet connection including your smartphone."
