5 Surprising NASA Heliophysics Discoveries Not Related to the Sun
With NASA’s fleet of heliophysics spacecraft, scientists monitor our Sun and investigate its influences throughout the solar system. However, the fleet’s constant watch and often-unique perspectives sometimes create opportunities to make discoveries that no one expected, helping us to solve…
Hurricane Helene’s Gravity Waves Revealed by NASA’s AWE
On Sept. 26, 2024, Hurricane Helene slammed into the Gulf Coast of Florida, inducing storm surges and widespread impacts on communities in its path. At the same time, NASA’s Atmospheric Waves Experiment, or AWE, recorded enormous swells in the atmosphere…
Final Venus Flyby for NASA’s Parker Solar Probe Queues Closest Sun Pass
On Wednesday, Nov. 6, 2024, NASA’s Parker Solar Probe will complete its final Venus gravity assist maneuver, passing within 233 miles (376 km) of Venus’ surface. The flyby will adjust Parker’s trajectory into its final orbital configuration, bringing the spacecraft…
30 Years On, NASA’s Wind Is a Windfall for Studying our Neighborhood in Space
Picture it: 1994. The first World Wide Web conference took place in Geneva, the first Chunnel train traveled under the English Channel, and just three years after the end of the Cold War, the first Russian instrument on a U.S.…
NASA to Launch Innovative Solar Coronagraph to Space Station
Editor’s Note: The CODEX instrument launched aboard NASA’s SpaceX 31st commercial resupply mission to the International Space Station at 9:29 p.m. EST on Nov. 4, 2024. On Nov. 11, robotics flight controllers in Houston successfully installed the instrument at Express…
NASA, NOAA: Sun Reaches Maximum Phase in 11-Year Solar Cycle
In a teleconference with reporters on Tuesday, representatives from NASA, the National Oceanic and Atmospheric Administration (NOAA), and the international Solar Cycle Prediction Panel announced that the Sun has reached its solar maximum period, which could continue for the next…
ESA/NASA’s SOHO Spies Bright Comet Making Debut in Evening Sky
The Solar and Heliospheric Observatory (SOHO) has captured images of the second-brightest comet to ever pass through its field of view, comet C/2023 A3 Tsuchinshan-ATLAS.
Voyager 1 Team Accomplishes Tricky Thruster Swap
The spacecraft uses its thrusters to stay pointed at Earth, but after 47 years in space some of the fuel tubes have become clogged. Engineers working on NASA’s Voyager 1 probe have successfully mitigated an issue with the spacecraft’s thrusters,…
NASA, ESA Missions Help Scientists Uncover How Solar Wind Gets Energy
Since the 1960s, astronomers have wondered how the Sun’s supersonic “solar wind,” a stream of energetic particles that flows out into the solar system, continues to receive energy once it leaves the Sun. Now, thanks to a lucky lineup of…
NASA Discovers a Long-Sought Global Electric Field on Earth
An international team of scientists has successfully measured a planet-wide electric field thought to be as fundamental to Earth as its gravity and magnetic fields. Known as the ambipolar electric field, scientists first hypothesized over 60 years ago that it…
