On Nov. 6, NASA’s Parker Solar Probe passed within 234 miles (376 kilometers) of Venus’ surface. The purpose of this close flyby was to accomplish a gravity-assist maneuver, in which the probe would steal some of Venus‘ momentum to change the spacecraft’s orbit and bring itself even closer to the sun. The Parker Solar Probe had already made several close passes of the sun, but the recent flyby was its closest, coming within about 3.8 million miles (6 million km) of the solar surface. That’s less than nine times the…

Hurricane Helene’s Gravity Waves Revealed by NASA’s AWE
2 min read 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 that the hurricane produced roughly 55 miles above the ground. Such information helps us better understand how terrestrial weather can affect space weather, part of the research NASA does to understand how our space environment can disrupt satellites, communication…
Read MoreSun erupts with powerful X2.3 solar flare, triggers radio blackouts (video)
The sun erupted with an X2.3-class solar flare this morning, triggering radio blackouts The X-class solar flare was released from a sunspot region AR 3883 at 8:40 a.m. ET (1340 UTC) on Wednesday morning (Nov. 6). Sunspots are darker, cooler locations on the sun that measure the size of planets and denote where the sun’s strong magnetic field roils up to its surface. It was the sunspot region’s strongest flare yet. According to Spaceweather.com, the wait is on for scientists to receive data from the coronagraph on the joint NASA/European Space…

5 min read 30 Years On, NASA’s Wind Is a Windfall for Studying our Neighborhood in Space An artist’s concept of NASA’s Wind spacecraft outside of Earth’s magnetosphere. NASA 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. spacecraft launched into deep space from Cape Canaveral. The mission to study the solar wind, aptly named Wind, held promise for…

5 min read NASA to Launch Innovative Solar Coronagraph to Space Station NASA’s Coronal Diagnostic Experiment (CODEX) is ready to launch to the International Space Station to reveal new details about the solar wind including its origin and its evolution. Launching in November 2024 aboard SpaceX’s 31st commercial resupply services mission, CODEX will be robotically installed on the exterior of the space station. As a solar coronagraph, CODEX will block out the bright light from the Sun’s surface to better see details in the Sun’s outer atmosphere, or corona. In…
Read MoreWatch sun erupt in 1st images from NOAA’s groundbreaking new satellite (photos)
The first images from a new space-based telescope launched into Earth’s orbit to monitor the sun captured a striking solar storm outburst. The National Oceanic and Atmospheric Administration (NOAA) shared the first images taken by its Compact Coronagraph (CCOR-1), the world’s first operational space-based coronagraph. CCOR-1 is mounted on NOAA’s newest geostationary satellite, GOES-19, which launched into orbit above Earth on June 25. CCOR-1 began its mission to observe the sun’s corona — the faint outermost layer of the solar atmosphere — on Sept. 19. The powerful solar telescope uses…
Read MoreSolar Cycle 25 is still in max phase, so more aurora-boosting sun storms could be coming
You could get more opportunities to see supercharged auroras over the next few months, thanks to our very active sun. Solar activity waxes and wanes on an 11-year cycle. The current cycle, known as Solar Cycle 25, began in December 2019 and is still in its maximum phase, experts say. “Currently, we’re about two years into the maximum period, so we’re anticipating another year or so of maximum phase before we really enter the declining phase, which will lead us back to solar minimum,” Lisa Upton, co-chair of the Solar…
Read MoreSevere solar storm could supercharge auroras across US, impact power grids, NOAA warns
Get ready, aurora chasers: There’s a good chance you’ll be able to catch a nice light show by the end of the week! Forecasters with the U.S. National Oceanic and Atmospheric Administration (NOAA)’s Space Weather Prediction Center (SWPC) are highlighting the potential for a severe geomagnetic storm on Thursday (Oct. 10) and Friday (Oct. 11). That storm is likely to be in the G4 class — the second-highest level on the SWPC’s geomagnetic storm scale, which takes into account both severity and potential impacts. Indeed, the SWPC has issued a…
Read MoreCould we turn the sun into a gigantic telescope?
We have some incredibly powerful telescopes that have given us spectacular views of the cosmos and allowed us to look back to the early days of the universe. These observatories, such as the James Webb Space Telescope (JWST), are amazing feats of engineering that have required billions of dollars and decades of work. But what if we could access an even better telescope that already exists? This wouldn’t be a typical telescope. It wouldn’t even come with a lens. But it would be by far the most powerful telescope we’d…
Read MoreSun fires off X-class solar flare, increasing aurora viewing chances into weekend
A parade of solar activity continues to flow from the sun this week, opening up more chances to spot the aurora across the United States this weekend. On Thursday morning (Sept. 12), a sunspot region that has not been numbered yet made its presence known blasting off a X1.3 class solar flare. X-class solar flares are the most powerful of their kind, and are typically followed by a full or partial loss of high frequency (HF) radio signals for sunlit locations on our planet. The energetic eruption, which peaked at…
