+== This Star Orbits So Close to Our Galaxy’s Black Hole That Spacetime Twists Around It ==
+The star's orbit appears to be closely linked to the black hole's spin—a characteristic of black holes astronomers have long struggled to measure.
+Gayoung Lee - August 19, 2026, 11:00 am ET
+Most galaxies are known to host a supermassive black hole at their centers, and supermassive black holes are known to spin. There’s still a lot scientists don’t understand about these two statements, thanks to the general elusiveness of black holes, but the discovery of an odd star in the heart of our galaxy may offer new insights into the mystery.
+In a paper published today in Nature, astronomers report the discovery of S301, an extremely faint star orbiting Sagittarius A*, the supermassive black hole at the center of the Milky Way. While S301 isn’t the only star to orbit Sagittarius A*, its journey around the black hole is the closest and fastest ever known. At its closest, the star approaches the black hole at a distance roughly equivalent with that between the Sun and Saturn. The extreme orbit of the star appears to be closely linked to the black hole’s spin, which could offer astronomers an unprecedented opportunity to directly measure the spin of a black hole.

+== NASA's PUNCH mission can now accurately predict when solar storms will hit Earth ==
+It was accurate to within a half hour during initial tests.
+Mariella Moon - Aug. 5, 2026 8:01 am EST
+In March 2025, NASA launched the Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission in an effort to better understand solar weather. It consists of a constellation of four microsatellites, monitoring the sun 24/7. Those satellites started taking images of coronal mass ejections (CMEs), which are explosive expulsions of materials from the sun into space, as soon as they arrived in orbit. Now, the PUNCH team has taken those images and data to show how much the mission can improve solar storm forecasts.
+The scientists used continuous imagery of a coronal mass ejection that the PUNCH satellites took on May 31, 2025 to see if they could improve forecast modeling for solar storms. A CME causes solar storm, which happens when the solar materials from the blast reach Earth's atmosphere and magnetic field.
+The team fed the data into a computer model, which analyzed the edges of the CME over time and then used its speed and shape to calculate when it would reach Earth. It ultimately predicted after analyzing the first 12 hours of the coronal mass ejection, that the solar storm would arrive on Earth eight hours later. It was accurate to within half an hour, making it much better than current methods that have an error margin of five hours. That's because before PUNCH, our instruments could only track one-fifth of the CME's journey from the sun to our planet. PUNCH allows scientists to track CMEs all the way through and even captures images once every four minutes.

+== A Solar Superstorm Caused a GPS Glitch Bad Enough to Crash Self-Driving Cars ==
+The massive eruption threw GPS readings off by more than 33 feet (10 meters).
+Passant Rabie - September 2, 2026, 4:40 pm ET
+On November 11, 2025, the Sun unleashed a series of solar flares that struck Earth, triggering a severe geomagnetic storm that peaked for around six hours. The event triggered beautiful auroras across the skies, but it also wreaked havoc on crucial technology we rely on for our daily lives.
+In a new study published in the journal Geophysical Research Letters, a team of scientists measured the disruption to global navigation systems caused by the geomagnetic storm. The results revealed significant positioning errors, large enough to mess with precision agriculture and autonomous vehicles across the U.S.

+Scientists using the U.S. National Science Foundation Daniel K. Inouye Solar Telescope have made a major breakthrough in solar physics, discovering Kelvin-Helmholtz Instability on the surface of the Sun — a finding that could help explain explosive solar activity and other solar phenomena.
+SUMMARY: The U.S. National Science Foundation National Solar Observatory (NSF NSO) announced today a major breakthrough in solar physics. Using the world’s most powerful solar telescope, the NSF Daniel K. Inouye Solar Telescope near the summit of Maui’s Haleakalā, combined with computer simulations, an international team of scientists from the NSO, NSF NCAR High Altitude Observatory (HAO), and the Max Planck Institute for Solar System Research (MPS) found the signature of Kelvin-Helmholtz instability (KHI), tiny swirling patterns like small whirlpools, on the Sun’s surface. Researchers suggest that KHI might be a key reason why the Sun’s outer atmosphere gets so hot, and why magnetic energy builds up and moves around on the Sun. Magnetic energy fuels solar flares and eruptions—the kind of solar activity that can send bursts of energy toward Earth and affect satellites, power grids, and other technology. The discovery opens a new window into the fundamental physics of the Sun and other stars while underscoring the unmatched capabilities of the Inouye Solar Telescope.

+Cheyenne MacDonald - Aug. 30, 2026 2:25 pm EST
+The Nancy Grace Roman Space Telescope has officially launched on its mission to explore dark matter, dark energy and other mysteries of the universe. NASA's new space telescope, which is able to image swaths of the sky 100 times larger than what Hubble could capture, launched this morning from NASA's Kennedy Space Center on a SpaceX Falcon Heavy rocket.
+The space agency confirmed shortly after launch that Roman had successfully deployed its solar panels and lower instrument sun shade. Over the coming days and weeks, the rest of its instruments will deploy and activate. Once it's all up and running, NASA says Roman will send home 1.4 terabytes of data a day. We can expect to see its first images in early 2027.

+== SpaceX Launching NASA's Roman Space Telescope to Explore Dark Energy and Habitable Planets ==
+Posted by EditorDavid on Sunday August 30, 2026 04:22AM
+SpaceX is scheduled to launch the Roman Space Telescope on a Falcon Heavy rocket, with the launch window opening at 7:26 a.m. EDT (1126 GMT). NASA will carry the launch live on YouTube.
+CNN offers this mission overview from NASA Administrator Jared Isaacman. "Roman will investigate dark matter, dark energy and the structure of the universe itself, and accelerate the future of discovery of potentially habitable planets outside our solar system." In fact, "NASA anticipates that Roman will image more than 50 times as much of the sky in the next five years as Hubble covered in three decades," reports USA Today, noting that "every single image it beams back to Earth will contain the equivalent of 100 pictures Hubble would capture."
+<blockquote>
+The barrel-shaped Roman telescope is due to set up operations nearly 1 million miles from Earth and begin scouring previously unobservable areas of the cosmos... NASA will make all of Roman's data available for anyone to peruse, meaning astronomers from all over the world will have the opportunity to make use of the observatory for advanced research, NASA says... Spanning 42 feet long and more than 14 feet wide, the Nancy Grace Roman Space Telescope is outfitted with two primary instruments

+== Europa’s Hidden Ocean May Be Even Harder to Reach Than We Thought ==
+For a long time, scientists assumed that the tiny water pools at Europa's surface came from the moon's deep, icy oceans. But is that physically possible?
+Gayoung Lee - July 24, 2026, 4:45 pm ET
+Earlier this year, researchers warned against the dangers of “fluffy ice” on Europa’s surface. If unaccounted for, missions headed to Jupiter’s moon could drown themselves in its deep, icy oceans. A new study suggests that this won’t happen—but for reasons that won’t make our Europa trips any easier.
+A paper published yesterday in Nature Astronomy challenges the assumption that the shallow pools of water on Europa’s surface represent a direct access route to the moon’s deep, icy oceans. In theory, this supposed access route could make it easier for a probe to explore how liquid water from Europa’s deep oceans traveled through cracks in the ice to the surface. Unfortunately, we’re not sure if this even happens.
+“This is exactly what we wanted to test,” Lujendra Ojha, the study’s first author and an earth scientist at Rutgers University, told Gizmodo. “In particular, we asked whether the water could travel this distance before losing enough heat to freeze and whether the fractures could remain open long enough to transport a meaningful amount of water.”

+Anna Washenko - Updated: Sept. 2, 2026 3:38 pm EST
+NASA announced today that it has awarded Blue Origin the contract to develop the Mars Telecommunications Network. The company has taken a deal worth potentially $700 million to create a high-performance Mars telecommunications orbiter for the agency by December 31, 2028. Once operational, the orbiter will transmit "science data, imagery, navigation information, and critical mission communications for spacecraft operating on and around the planet."
+The space agency is using its Artemis program to explore the moon. Progress has been slow but resulted in a successful human crewed mission earlier this year, and those missions will serve as preparation to eventually send astronauts to Mars. NASA will need more data as it continues to work toward that goal, so having a reliable way to send that information from the Red Planet to the Blue Dot will be essential.
+Blue Origin has already worked with the space agency, securing a contract to build lunar landers at the start of this year. In May, the company's New Glenn rocket program took a setback after a launchpad explosion, but Blue Origin's CEO claimed repairs on the launchpad would be done by the end of 2026.

+For more than a decade, NASA’s Curiosity rover has been trudging up Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain at the center of the Gale Crater on Mars. Scientists believe lakes and streams covered the foothills of this peak billions of years ago, and Curiosity just found an abundance of evidence to support that hypothesis.
+The rover captured a 360-degree panorama inside a valley nicknamed “Valle Grande” on June 19 and 20, revealing a vast plain of honeycomb-like surface features stretching as far as its Mast Camera could see. The image is made up of 340 individual snapshots that Curiosity beamed back to Earth, where scientists stitched them together. While this isn’t the first time the rover has spotted these “polygonal fractures,” as NASA calls them, it has never found so many in one place before.
+“We’ve seen a lot of fascinating landscapes through Curiosity’s eyes, but this sea of polygons took our breath away,” Ashwin Vasavada, the project scientist for Curiosity, said in a statement. “We measured their shapes and chemistry carefully and are hopeful there are clues in the data as to how these features formed.”

+== Scientists Drastically Underestimated How Much Mercury Has Shrunk ==
+A new estimate of Mercury's shrinkage shows that this planet may have contracted 10% to 30% more than previous research suggested.
+Ellyn Lapointe - September 10, 2026, 9:00 am ET
+Mercury, the littlest planet in our solar system (though Pluto apologists may beg to differ), is getting smaller by the day. In fact, it’s been slowly shriveling up ever since it formed roughly 4.5 billion years ago. A new analysis of its shrinkage, or “radial contraction,” throws earlier estimates into question.
+The findings, published today in the journal Geophysical Research Letters, suggest Mercury has shrunk a whopping 10% to 30% more than previous studies found. The new estimate equates to a loss of roughly 12 miles (19 kilometers) of total diameter since the planet formed.
+“Mercury’s radial contraction provided in previous works has been underestimated because of lack of consideration of recent geologies,” lead author Gaku Nishiyama, a planetary scientist at the German Aerospace Center (DLR) Institute of Space Research, told Gizmodo in an email. By “recent geologies,” Nishiyama means geologically young impact craters and their ejected debris, which can obscure signs of the planet’s shrinkage.
+“Our study solved this point for the first time by using surface roughness of Mercury [to] successfully estimate how much radial contraction has been missed in previous works,” he explained.
