| | Earth and Its Climate
Scientists at Goddard study land, sea, ice and air to understand our changing climate. We use our satellites, technology and know-how to peer into the ozone hole, see the ingredients of hurricanes, study earthquakes, gravity, pollution, melting glaciers and ice caps. We strive to understand and protect our home planet by learning more about it, and how to take care of it. See some of our most popular stories about climate, hurricanes, and environment below:

The Sun, Our Closest Star
The Sun is a thermonuclear fusion furnace some 800,000 miles (1.3 million km) wide. It has been running for about five billion years, but if just one second of its output could be collected, it would power the entire United States for nine million years. Like any furnace, sometimes it's temperamental, unleashing explosions with the power of a billion one-megaton nuclear bombs, or blasting billions of tons of electrified gas or plasmas into space at millions of miles per hour. Such solar wind plasmas are always present and dramatically affect the geospace environment; however, harzardous conditions for technological systems and astronauts are greatly enhanced during these violent outbursts. Stormy solar activity occasionally disrupts satellites, communications, and power systems. NASA Goddard employs a fleet of missions to better understand the vital but restless Sun, our closest star.
