Severe solar storm could supercharge auroras across US, impact power grids, NOAA warns

NeRD

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…

Comet Tsuchinshan-ATLAS photobombs SOHO spacecraft during powerful solar flare (video)

NeRD

Nothing makes a photo more interesting than an unexpected guest appearing in the background. And how cool would it be if the photobomber were a comet? That’s exactly what happened to the sun-studying Solar and Heliospheric Observatory (SOHO) spacecraft, a joint effort of the European Space Agency (ESA) and NASA, beginning on Oct. 7. Typically, scientists use the view from SOHO’s Large Angle Spectrometric Coronagraph (LASCO) instrument to monitor the sun’s activity and determine if a coronal mass ejection (CME) accompanies a solar flare from active sunspot regions. Coronographs block…

Record-breaking ancient spinning galaxy challenges cosmic evolution theories

NeRD

The most distant and thus earliest rotating disk galaxy ever spotted has surprised astronomers and could challenge our theories of galactic evolution. Not only does it seemingly exist too early in the cosmos to be strongly spinning, the galaxy also shows hints of spiral arms similar to highly evolved “modern” galaxies like our own Milky Way. The galaxy, designated REBELS-25, is seen as it was just 700 million years after the Big Bang, at a time when astronomers expect galaxies to have been small and messy. Living up to its…

Can Rocket Lab come to NASA’s rescue with new Mars sample-return plan?

NeRD

NASA’s troubled Mars sample-return program may have a new lifeline, in the form of a proposal from private space company Rocket Lab to help save the mission. When the Perseverance rover landed on Mars in 2021, the plan was to follow up with a mission in the early 2030s that would retrieve the canisters containing samples of Martian dirt, rocks and atmosphere collected by the rover, and bring them to Earth for detailed study. The hope is that the samples will be able to tell researchers about conditions on Mars…

Satellite images capture Hurricane Milton intensifying into Category 5 storm (videos)

NeRD

In the heart of the Gulf of Mexico, a new hurricane is brewing. Hurricane Milton, now having intensified into a Category 5 storm, was caught in incredible space-based imagery from spacecraft such as the U.S. National Oceanic and Atmospheric Administration’s GOES-East satellite.  Hurricane Milton comes just ten days after Hurricane Helene, the deadliest hurricane to hit the United States since Katrina, made landfall in the southeastern U.S.  Milton poses a solid threat to the regions it will impact, and the National Hurricane Center is urging residents of Florida to take…

Ancient supermassive black hole is blowing galaxy-killing wind, James Webb Space Telescope finds

NeRD

Using the James Webb Space Telescope (JWST), astronomers have spotted the earliest powerful “galaxy-size” wind blowing from a feeding supermassive black hole-powered quasar. The powerful wind is pushing gas and dust from its galaxy at incredible speeds, killing star birth in its host galaxy.  This quasar, designated J1007+2115, is so distant that it is seen as it was just 700 million years after the Big Bang — when the 13.8 billion-year-old universe was just around 5% of its current age. Though this makes J1007+2115 just the third-earliest quasar ever seen,…

NASA’s exoplanet hunter TESS spots a record-breaking 3-star system

NeRD

Using NASA’s exoplanet-hunting spacecraft, the Transiting Exoplanet Survey Satellite (TESS), scientists have spotted a record-breaking triple-star system so tightly bound that it could fit comfortably between the sun and its closest planet, Mercury. The system, designated TIC 290061484 contains twin stars that race around each other once every 1.8 Earth days as well as a third star that orbits this pair once every 25 Earth days. This triple star system’s super-tight orbit, located just under 5,000 light-years away in the constellation Cygnus, the swan, makes it a record-breaker.  The previous…

China unveils spacesuit for moonwalking astronauts (video)

NeRD

China has strutted out its moon-landing spacesuit, unveiling its design in a ceremony Saturday (Sept. 28) in southwest China’s Chongqing Municipality. A technician put the spacesuit — which China aims to start using on crewed moon missions by 2030 — through its paces, showcasing various movements and gestures, including climbing the rungs of a ladder.  The overall design of the moon-landing suit is inspired by traditional Chinese armor, underscoring the suit’s rugged and resolute appearance. It also features ribbons, which have always been an important element in the design of Chinese…

The Milky Way’s 2 biggest satellite galaxies are oddly lonely, study finds

NeRD

The Milky Way’s system of small, orbiting satellite galaxies is quite unusual, a new 12-year study of other galaxies in the local universe has found.  The Satellites Around Galactic Analogs (SAGA) survey is being conducted by a small group of astronomers to learn how the Milky Way and its little retinue of dwarf satellite galaxies compares to other galaxy systems. “The Milky Way’s satellite population is a unique combination of small satellites containing only older stars, and its two largest satellites, which are actively forming new stars,” says Marla Geha,…
