A method has been developed to study extreme space weather events

The results can help to better understand and predict the most extreme space weather events and their potential to cause strong geomagnetic storms that directly affect the operation of engineering systems in space and on Earth.

ESO telescope observes exoplanet where it rains iron

Researchers using ESO’s Very Large Telescope (VLT) have observed an extreme planet where they suspect it rains iron. The ultra-hot giant exoplanet has a day side where temperatures climb above 2400 degrees Celsius, high enough to vaporise metals. Strong winds carry iron vapour to the cooler night side where it condenses into iron droplets. “One…

NASA Selects Missions to Study Our Sun, Its Effects on Space Weather

From NASA June 20, 2019 RELEASE 19-047 https://www.nasa.gov/sites/default/files/thumbnails/image/solarwind.png NASA has selected two new missions to advance our understanding of the Sun and its dynamic effects on space. One of the selected missions will study how the Sun drives particles and energy into the solar system and a second will study Earth’s response. The Sun generates…

Seeing an Aurora From the Space Station

From NASA  click on image for high resolution version~ctm June 13, 2019 Aboard the International Space Station, NASA astronaut Christina Koch snapped this image of an aurora, saying: “Years ago at the South Pole, I looked up to the aurora for inspiration through the 6-month winter night. Now I know they’re just as awe inspiring…

New Satellites Target Space Weather Threat

WHO’S AFRAID OF KILLER ELECTRONS?  “Killer electrons” from the Van Allen Belts are raining down on Earth’s atmosphere. Last Saturday, a Delta II rocket blasted off at dawn from Vandenberg AFB in California. Soon thereafter NASA reported the successful deployment of the ICESat-2 satellite, designed to make 3D laser images of Earth’s surface. Here’s what…
