The Star That Shouldn't Exist
A red giant orbiting a dormant black hole is spinning impossibly fast and contains chemistry that makes it look ancient when it's actually relatively young. By listening to faint vibrations rippling through the star, astronomers have decoded a violent secret, that this star likely collided with and absorbed another star billions of years ago, an explosive merger that left it chemically confused and rotating once every 398 days. The discovery reveals how even quiet black hole systems can have turbulent histories written in starlight.
After a Century of Searching, We May Have Finally Seen Dark Matter
Ninety five years after Swiss astronomer Fritz Zwicky inferred its existence from galaxies moving impossibly fast, researchers may have detected the first direct evidence of dark matter, the invisible scaffolding that holds the universe together. Using gamma ray data from NASA's Fermi Space Telescope, a Japanese physicist has identified a halo of extremely energetic photons around the Milky Way's center that matches predictions for annihilating dark matter particles. If confirmed, humanity has finally "seen" the unseeable.

NASA Astronaut Chris Williams, Crewmates Arrive at Space Station
NASA astronaut Chris Williams, accompanied by Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, safely arrived at the International Space Station on Thursday, expanding the orbiting laboratory’s crew to 10 for the next two weeks.
The trio launched aboard the Soyuz MS-28 spacecraft at 4:27 a.m. EST (2:27 p.m. Baikonur time) from the Baikonur Cosmodrome in Kazakhstan. After a three-hour, two-orbit journey, the spacecraft docked at 7:34 a.m. to the space station’s Rassvet module.
Following hatch opening, expected about 10:10 a.m., the new arrivals will be welcomed by the Expedition 73 crew, including NASA astronauts Mike Fincke, Zena Cardman, and Jonny Kim; JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui; and Roscosmos cosmonauts Sergey Ryzhikov, Alexey Zubritsky, and Oleg Platonov.
NASA’s live coverage of hatch opening begins at 9:50 a.m. on NASA+, Amazon Prime, and YouTube. Learn how to watch NASA content through a variety of platforms, including social media.
During his stay aboard the space station, Williams will conduct scientific research and technology demonstrations aimed at advancing human space exploration and benefiting life on Earth. He will help install and test a new modular workout system for long-duration missions, support experiments to improve cryogenic fuel efficiency and grow semiconductor crystals in space, as well as assist NASA in designing new re-entry safety protocols to protect crews during future missions.
Expedition 74 is scheduled to begin on Monday, Dec. 8, following the departure of Kim, Ryzhikov, and Zubritsky, as they conclude an eight-month science mission aboard the orbital outpost.
Watch the change of command ceremony at 10:25 a.m. on Sunday, Dec. 7, as station leadership transfers from Ryzhikov to Fincke, live on NASA+.

Devastating Stellar Storm Seen on Red Dwarf Star
On Earth, Coronal Mass Ejections (CMEs) like the one we experienced earlier this month are aesthetic, even disruptive events, sending aurora southward and interrupting radio signals. But around other stars, they could prove lethal to life. This point was driven home by a recent CME detection from an M-class red dwarf star. This marks the first detection of an energetic Type II radio burst from a nearby star.
Why Being in the "Right Place" Isn't Enough for Life
A planet’s habitability is determined by a confluence of many factors. So far, our explorations of potentially habitable worlds beyond our solar system have focused exclusively on their position in the “Goldilocks Zone” of their solar system, where their temperature determines whether or not liquid water can exist on their surface, and, more recently, what their atmospheres are composed of. That’s in part due to the technical limitations of the instruments available to us - even the powerful James Webb Space Telescope is capable only of seeing atmospheres of very large planets nearby. But in the coming decades, we’ll get new tools, like the Habitable Worlds Observatory, that are more specifically tailored to search for those potentially habitable worlds. So what should we use them to look for? A new paper available in pre-print on arXiv by Benjamin Farcy of the University of Maryland and his colleagues, argues that we should look to how a planet formed to understand its chances of harboring life.
Cranberry Country, Wisconsin
Known as America’s Dairyland, Wisconsin produces the most cheese of any state and trails only California in the production of milk. Less famously, the state outpaces all others in a key part of many Thanksgiving menus. Wisconsin is the leading producer of cranberries in the U.S., with its annual hauls accounting for more than half of the country’s total yield.
The wetlands, cool climate, and sandy, acidic soils of central and northern Wisconsin provide the foundation for raising the tart berry successfully. This satellite image shows geometric networks of cranberry beds alongside small lakes near the town of Warrens, the “Cranberry Capital of Wisconsin.” It was acquired with the OLI-2 (Operational Land Imager-2) on Landsat 9 on October 13, 2025, during the autumn harvest season.
When berries are ripe, growers flood fields with up to a foot of water and then use specialized machines to knock fruit off the vines. Because cranberries contain pockets of air, they float to the surface—turning entire fields red—to be corralled and removed. Beds are not all flooded at once; satellite images acquired throughout the fall show different areas appearing red at different times.
Cranberries are native to Wisconsin marshes, and Native Americans have harvested the fruit for centuries. Commercial production in Wisconsin began in the mid-19th century and expanded as technology and cultivation methods improved. Around 1950, harvesting largely shifted from hand rakes to machines. By 1956, Wisconsin was the second-largest cranberry producer in the U.S. after Massachusetts, and in 1994 it took over the top spot. Today, cranberries in Wisconsin are an approximately $1 billion industry that employs nearly 4,000 people.
In mid-November, as Thanksgiving approaches, the brilliant red berries are on their way to be sold in markets or processed for use in sauces, juices, and other products. Meanwhile, the vines turn deep purple and go dormant. Growers prepare the beds for winter by again flooding the fields to cover plants in a protective layer of ice. They also coat the ice in sand, which will become part of the substrate and rejuvenate growth in the spring. With the right care, a cranberry plant can produce fruit for 50 years or more.
