NASA researchers will present new findings on a wide range of Earth and space science topics at the annual meeting of the American Geophysical Union.
NASA's Cassini spacecraft has sent to Earth its first views of Saturn’s atmosphere since beginning the latest phase of its mission.
Toolkits are compilations of free downloadable resources with various science themes. For example, toolkits may contain ready-to-print posters, social media graphics, or bookmark templates . Topics include Mars, total solar eclipses, and science calendars. Explore and download these resources today!
Imagine standing around a roaring campfire, roasting s’mores. You feel the warmth of the flames as the marshmallows crackle. Now back away. You get cooler, right?
That's not how it works on the sun. The visible surface of the sun has a temperature of 10,000° F. Backing away from the inferno should cool things down, but it doesn’t. Instead, the sun's upper atmosphere, or corona, sizzles at millions of degrees - a temperature 200 to 500 times higher than that of the roaring furnace below.
Prior to the 1960’s, the biggest storms on Earth could take people by surprise. Someone standing on a beach in Florida might not know if a distant bank of clouds was a routine squall or … the harbinger of a powerful hurricane.
Step outside on October 16, and take a look at the moon. Not only will the moon be full, but on that day, the moon will be at its closest point to our planet as it orbits Earth. This makes the October full moon a supermoon.
In 1963, an astronomy student named Gail Smith working at an observatory in the Netherlands discovered something odd—a massive cloud of gas orbiting the Milky Way galaxy. Smith’s cloud contained enough gas to make 2 million stars the size of our sun, and it was moving through space at 700,000 mph.
For the next 40+ years the cloud remained a curiosity, one of a growing number of so-called high velocity clouds circling the Milky Way--interesting but not sensational.
“It’s absolutely thrilling to be embarking on this journey. Today, NASA is leading efforts to answer a host of important questions for humanity: Where do we come from? How did life originate? How are Earth's environments changing? There has never been a more pivotal time to solve these mysteries, and I'm looking forward to the charge."
Summertime airshows are fun to watch, especially when aircraft fly in tight formation. The sight of airplanes soaring overhead practically wingtip to wingtip is thrilling to behold.
Four of NASA’s spacecraft recently performed an equally thrilling maneuver: In Oct. 2015, the satellites of NASA’s Magnetospheric Multiscale, or MMS, mission gathered into a tetrahedral formation with each spacecraft at the tip of a four-sided pyramid only six miles across. Moving together as one, they raced around Earth at 15,000 mph.
