The Sun and its atmosphere consist of several zones or layers. From the inside out, the solar interior consists of: The Core – the central region where nuclear reactions consume hydrogen to form helium. These reactions release the energy that ultimately leaves the surface as visible light. The Radiative Zone – extends outward from the …
UPDATED Aug. 4, 2023: NASA has reestablished full communications with Voyager 2. The agency's Deep Space Network facility in Canberra, Australia, sent the equivalent of an interstellar "shout" more than 12.3 billion miles (19.9 billion kilometers) to Voyager 2, instructing the spacecraft to reorient itself and turn its antenna back to Earth. With a one-way …
Five researchers supported by NASA's Living With a Star Program will join the 2023-2024 class of NASA's Jack Eddy Postdoctoral Fellowship. The early career PhDs, selected by the University Corporation for Atmospheric Research (UCAR)'s Cooperative Program for the Advancement of Earth System Science (CPAESS), will research interdisciplinary projects contributing to the field of heliophysics at …
As Earth spins around the Sun, our planet's slight tilt creates seasons. Now, research from two NASA space missions has found how the same tilt also influences seasonal differences in space weather – conditions in space produced by the Sun's activity. Space weather events produce the beautiful glow of the northern and southern lights, but, …
After more than 15 years of scientific discoveries, NASA's Aeronomy of Ice in the Mesosphere, or AIM, spacecraft is no longer supporting operations after experiencing issues with its battery. AIM's batteries initially started to decline in 2019, but the Earth-studying spacecraft continued to return a significant amount of data. Now, with further decline in the …
A massive eruption of solar material, known as a coronal mass ejection or CME, was detected escaping from the Sun at 11:36 p.m. EDT on March 12, 2023. The CME erupted from the side of the Sun opposite Earth. While resarchers are still gathering data to determine the source of the eruption, it is currently …
NASA's Interstellar Boundary Explorer (IBEX) is fully operational after the mission team successfully reset the spacecraft on March 2. To take the spacecraft out of a contingency mode it entered last month, the mission team performed a firecode reset (which is an external reset of the spacecraft) instead of waiting for the spacecraft to perform …
NASA's Interstellar Boundary Explorer (IBEX) experienced a flight computer reset during a planned contact and the spacecraft went into contingency mode on Feb. 18. While fight computer resets have happened before, this time the team lost the ability to command the spacecraft during the subsequent reset recovery. The team also was unsuccessful in regaining command …
The CubeSat to Study Solar Particles (CuSP) launched as an Artemis I payload on 1:47 AM EST on Nov. 16, 2022. CuSP was deployed from its canister about eight hours after launch. Approximately two hours after deployment, CuSP transmissions were received by an Open Loop Receiver (OLR) operated by NASA's Jet Propulsion Laboratory's Radio Science …
THE GREAT SPRITES CHASE A NASA scientist and night-sky fanatic chase the elusive lights across Oklahoma. The odds are not in their favor. By Lina Tran It wasn't dark enough. We'd driven east for two hours from Oklahoma City, and still, a stubborn red light blinked from a nearby wind farm. Paul Smith sighed with …
