Rossby Waves on the Sun Could Aid in Space Weather Prediction To predict weather on a planet, we look at Rossby waves, large movement patterns in the atmosphere, like the jet stream. Just as on Earth, the conditions on the sun are constantly changing. This is why scientists were excited to discover ...

Why Won't it Melt How NASA's Solar Probe will Survive the Sun NASA's Parker Solar Probe is heading to the Sun. Why won't the spacecraft melt? Thermal engineer Betsy Congdon (Johns Hopkins APL) outlines why Parker can take the heat. Heat , Melting , Solar Wind , Sun , Space Weather , Heliophysics , C...

https://youtu.be/oW4tRBtfdsc Snapshots from the Edge of the Sun For the first time, using NASA’s Solar Terrestrial Relations Observatory, or STEREO, scientists have imaged the edge of the sun and described that transition – from which the solar wind blows. Defining the details of this boundary helps...

https://youtu.be/skmxV0s7GSA Parker Solar Probe Mission Launches to Touch the Sun NASA’s Parker Solar Probe mission launched Aug. 12 from Cape Canaveral Air Force Station in Florida. The mission will be the first to fly directly through the Sun’s corona – the hazardous region of intense heat and sol...

It's Surprisingly Hard to Go to the Sun The Sun contains 99.8 percent of the mass in our solar system. Its gravitational pull is what keeps everything here, from tiny Mercury to the gas giants to the Oort Cloud, 186 billion miles away. But even though the Sun has such a powerful pull, it's surprisin...

Hinode Takes an X-Ray of a Powerful Solar Flare On Sept. 10, 2017, the Hinode satellite observed an enormous X-class flare burst from an active region on the western edge of the Sun. The video shows the high-energy flare as seen by Hinode's X-Ray Telescope. The emission was so bright that the initia...

Testing Space Lasers for Deep Space Optical Communications (Mission Overview) How might lasers revolutionize deep space communications? NASA will test high-bandwidth laser (or optical) communications for the first time beyond the Moon with a pioneering technology demonstration called Deep Space Opti...

How Do Sounds on Mars Differ from Sounds on Earth Did you know sound works differently on Mars than it does on Earth? Mars has a different atmosphere than Earth, so sounds on the Red Planet would sound a bit different and be more muffled. NASA’s Mars Perseverance rover has two microphones that recor...

Young Volcanoes on the Moon

The Moon might not be as dead as it looks. Researchers using NASA's Lunar Reconnaissance Orbiter have found signs of geologically-recent volcanic eruptions on Earth's natural satellite.
