How can I see the northern lights? To see the northern lights, you need to be in the right place at the right time. Auroras are the result of charged particles and magnetism from the Sun called space weather dancing with the Earth’s magnetic field. And they happen far above the clouds. So you need … Read more
Under the nighttime California sky, NASA’s EZIE (Electrojet Zeeman Imaging Explorer) mission launched aboard a SpaceX Falcon 9 rocket at 11:43 p.m. PDT on March 14. Taking off from Vandenberg Space Force Base near Santa Barbara, the EZIE mission’s trio of small satellites will fly in a pearls-on-a-string configuration approximately 260 to 370 miles above Earth’s surface to … Read more
High above Earth’s poles, intense electrical currents called electrojets flow through the upper atmosphere when auroras glow in the sky. These auroral electrojets push about a million amps of electrical charge around the poles every second. They can create some of the largest magnetic disturbances on the ground, and rapid changes in the currents can … Read more
In 2023 and 2024, two eclipses crossed the United States, and the NASA Science Activation program’s Eclipse Ambassadors Off the Path project invited undergraduate students and amateur astronomers to join them as “NASA Partner Eclipse Ambassadors”. This opportunity to partner with NASA, provide solar viewing glasses, and share eclipse knowledge with underserved communities off the … Read more
Peering through the window of the SpaceX Dragon Endeavour spacecraft, NASA astronaut Matthew Dominick captured this image on Oct. 7, 2024 of the SpaceX Dragon Freedom spacecraft as vivid green and pink aurora swirled through Earth’s atmosphere while the International Space Station soared 273 miles above the Indian Ocean. Visit Dominick’s photography on station to … Read more
NASA’s Solar Dynamics Observatory captured these images of the solar flare on May 14, 2024 — as seen in the bright flash on the right side. These images show a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in royal blue and gold. This flare shows … Read more
“NASA’s growing heliophysics fleet is well suited to continue to investigate the source regions of these radio bursts,” said Natchimuthuk Gopalswamy, a heliophysicist and solar radio researcher at NASA’s Goddard Space Flight Center. “For example, the Solar Dynamics Observatory continually monitors the Sun’s active regions, which likely give rise to this phenomenon.” Source link
Infrared emission from methane suggests atmospheric heating by auroral processes. Astronomers using NASA’s James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an unexpected discovery because the brown dwarf, … Read more
