Astronomers have identified what may be the first genuinely green star, a white dwarf called WD J1330+6435 located about 326 light-years from Earth. Space.com reports: The researchers found that some dead star white dwarfs can go a little green around the gills after snacking on orbiting planets. An example of this is WD J1330+6435, a cool white dwarf located around 326 light-years away, which has been accreting rocky material from a planetary companion. This has enriched its atmosphere with calcium, lithium, and sodium, and the team's model suggests this would have led WD J1330+6435 to adopt a green hue.
[...] The researchers think that no other star, living or dead, has ever been credibly reported as green. That makes WD J1330+6435 the first known genuinely green star. "The traces of sodium in the atmosphere of this white dwarf absorb the orange part of the spectrum, leaving behind a ghostly green glow," Hollands said. "Imagine standing on a planet and looking up at a green star. It feels like something out of science fiction." The researchers also discovered what may be the reddest star ever observed, the white dwarf WD J1011+2845, located just 48 light-years away.
The findings have been published in the journal RAS Techniques and Instruments.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Yi Lin, SPEARS testing and research lead at NASA Langley, holds one of the small coin-cell batteries that had just undergone thermal vacuum testing.

If you’ve ever had your car start sluggishly, or not at all, on a particularly frigid winter morning, you know standard batteries do not like extreme cold. That’s why NASA researchers are working to develop a battery that could function in the brutal cold of the Moon’s South Pole, where nighttime temperatures plunge to minus 328 degrees Fahrenheit (minus 200 Celsius).
For future lunar operations, a battery will need to work immediately when warmed up and be able to power everything from an astronaut’s emergency kit to a rover capable of exploring the Moon’s darkest craters — all without posing a fire hazard.
A team of NASA researchers is working to make all that happen. The project is called Solid Power for Extreme Environment Adaptability and Resilience in Space (SPEARS), and it could provide NASA with an important tool to help power humanity’s sustained presence on the Moon through the Artemis campaign.
“Batteries have become an important part of our lives here on Earth, which enable our laptops, cell phones, power tools, and even our vehicles,” said Donald Dornbusch, principal investigator for SPEARS at NASA’s Glenn Research Center in Cleveland, where the project is led. “We will need them on the Moon, too, and these batteries will be required to operate reliably and safely in this harsh environment. That’s why we’re working on this technology.”

Splashy problem, solid solution
Traditional lithium-ion batteries like those in your cell phone and laptop have a critical weakness: they rely on liquid electrolytes. Cool a conventional battery to the Moon’s nighttime temperatures, and that liquid would freeze, potentially damaging the battery. Heat it up too much — say, to daytime lunar temperatures of 212 F (100 C) — and it won’t work until cooled. Expose the liquid to the vacuum of space, and it evaporates.
SPEARS batteries solve these problems by replacing the liquid electrolyte with a solid ceramic- or polymer-based material. This change could unlock several advantages. First and foremost, they could operate in the heat and extreme cold.
During recent thermal vacuum testing at NASA’s Langley Research Center in Hampton, Virginia, small prototype battery cells operated well up to 176 F (80 C), down to minus 76 F (minus 60 C), and with slightly reduced performance down to minus 112 F (minus 80 C).
“We proved for the first time that these cells can work down to minus 80 degrees Celsius,” said Yi Lin, SPEARS testing and research lead at NASA Langley.
Lin also said he’s confident they can improve performance and maybe even expand that range in coming years.
The batteries need to remain reliable through exposure to the Moon’s wild temperature swings between day and night. The thermal vacuum testing showed that after exposure to temperature extremes from 212 F (100 C) to minus 274 F (minus 170 C), SPEARS batteries don’t sustain damage.
Just like the chemistry in your earbuds is different from the chemistry in your phone, which is different from the chemistry in your car, all these chemistries can still function with a solid electrolyte. We can tune for energy, tune for power, tune for durability, depending on the application.
Yi Lin
SPEARS testing and research lead
Not even solid-state batteries will function while they’re at a temperature as low as minus 274 F, but because solid electrolytes don’t freeze like a liquid, the batteries can survive the extreme low temperatures.
In order to get the batteries working again after exposure to such cold, small heaters come into play. SPEARS batteries wouldn’t need to be kept warm all the time, just warmed up to operational temperature. That could reduce the need for heavy thermal management systems in spacecraft and lunar habitats, allowing for lighter designs, lower costs, and longer mission durations.

Power for Moon, Earth
The applications for these solid-state batteries are nearly limitless, from small tools like drills that must operate in shadowed lunar craters, to rovers and emergency power packs for astronauts. They also could provide power solutions for long-duration scientific instruments.
“We can tune the chemistry by using different electrode materials,” said Lin. “Just like the chemistry in your earbuds is different from the chemistry in your phone, which is different from the chemistry in your car, all these chemistries can still function with a solid electrolyte. We can tune for energy, tune for power, tune for durability, depending on the application.”
While SPEARS is designed for space, the technology could be spun off into Earth-based applications. In fact, SPEARS evolved out of a previous battery project Lin and Dornbusch worked on that focused on aeronautic applications.

“The potential market for solid-state batteries is very broad,” said Ji Su, a polymer materials scientist and the task lead at NASA Langley. “Automobiles, cell phones, communication devices, drones — anything that needs a portable power supply.”
The SPEARS project began in 2026 with funding through the Advanced Research and Technology division within the agency’s Research and Technology Mission Directorate. The project is set to focus on technology development in its first stages before potentially shifting toward commercial collaboration. NASA’s Ames Research Center in California’s Silicon Valley is working to develop flight hardware such as test boards and electronics to help prepare the SPEARS batteries for spaceflight and test them in space environments.
A SpaceX Falcon 9 rocket and Dragon spacecraft launched on Tuesday, Oct. 13, 2026, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida as part of the company’s 35th Commercial Resupply Services mission to the International Space Station for NASA.

NASA’s SpaceX 35th commercial resupply mission lifted off at 6:33 a.m. EDT Tuesday aboard a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida, carrying more than 6,300 pounds of supplies and hardware, bound for the International Space Station. Following its successful launch, the SpaceX Dragon spacecraft will carry new scientific experiments, cargo, and the final pair of International Space Station Roll-Out Solar Arrays to the orbiting laboratory.
Dragon is scheduled to autonomously dock at 11 a.m., Thursday, Oct. 15, to the space-facing port of the space station’s Harmony module. NASA will stream rendezvous and docking coverage beginning at 9:15 a.m., through a variety of platforms. Learn where to watch online:
The final pair of solar arrays will complete the space station’s power system augmentation, boosting available electricity for research, operations, and the station’s safe, controlled deorbit. Astronauts will install the arrays during a series of spacewalks planned for later this fall.
Dragon also is delivering several new experiments, including hardware to manufacture artificial retinas in microgravity that could help restore vision for patients on Earth and 3D heart tissue models to advance large-scale drug testing on future space missions. Dragon also will carry materials to study how a new type of glass is formed in microgravity, and brain organoids that could uncover potential treatment targets for neurodegenerative diseases like Alzheimer’s, Parkinson’s, and multiple sclerosis.
These are just a sample of the hundreds of investigations conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Research and technology investigations taking place aboard the space station benefit people on Earth and lay the groundwork for other agency deep space missions. As part of NASA’s Artemis program, the agency will send astronauts to the Moon to prepare for future human exploration of Mars, inspiring the world through discovery in a new Golden Age of innovation and exploration.
The Dragon spacecraft is scheduled to remain at the space station until mid-November when it will depart and return to Earth with time-critical research and cargo, splashing down off the coast of California.

After more than seven months aboard the International Space Station, NASA’s SpaceX Crew-12 mission safely splashed down Thursday in the Pacific Ocean off the coast of Los Angeles. The crew members will discuss their science mission during a news conference at 3:30 p.m. EDT, Thursday, Oct. 15, at the agency’s Johnson Space Center in Houston.
“Jessica, Jack, Sophie, and Andrey spent 237 days living and working in orbit, traveled more than 100 million miles, advanced important science, and returned safely home because of the extraordinary expertise and competence of thousands across NASA, SpaceX, and our international partners,” said NASA Administrator Jared Isaacman. “Building the capability, experience, and confidence to do this repeatedly is exactly what will allow us to go farther, and I am grateful to Crew-12 and their families for their service to humanity’s greatest adventure.”
NASA astronauts Jessica Meir and Jack Hathaway, ESA (European Space Agency) astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev returned to Earth at 8:34 a.m. PDT. Teams aboard SpaceX recovery vessels retrieved the spacecraft and its crew shortly after. Following standard postflight medical screenings, the crew will fly to shore before returning to NASA’s Johnson Space Center in Houston.
“NASA’s activities supporting the International Space Station — transporting crew, conducting impactful research, and maintaining critical national assets — enable the science, engineering, and risk‑reduction needed for future missions across the solar system,” said Dana Weigel, manager of NASA’s Low Earth Orbit Program at the agency’s Johnson Space Center. “We’re grateful for the dedication across the human spaceflight team that makes this possible, and we’re thrilled to welcome Jessica, Jack, Sophie, and Andrey home.”
During their 237-day mission, the four crew members traveled more than 100 million miles and completed more than 3,792 orbits around Earth. The mission was the second for Meir and Fedyaev and the first for Hathaway and Adenot. Crew-12 lifted off at 5:15 a.m. EST on Feb. 13 and docked to the orbiting laboratory a day later.
Crew‑12 logged hundreds of hours of scientific research to support human exploration beyond low Earth orbit and advance benefits for people on Earth. The crew members’ work included testing stem cell production for cell‑based therapies, demonstrating on‑demand IV fluid generation for future missions, and studying how the bacteria that causes pneumonia can lead to long‑term heart damage. The crew also conducted nutrition-focused research and examined how physical characteristics may affect blood flow during spaceflight to help keep astronauts safe and healthy on future missions. Research conducted aboard the space station advances knowledge and demonstrates new technologies that enable us to prepare for human exploration of the Moon and Mars.
Meir completed four spacewalks, bringing her career total to seven. That places her third all-time in total spacewalks among women at NASA, behind former agency astronauts Peggy Whitson and Suni Williams. Adenot completed three spacewalks, becoming the first French woman to venture outside the orbital outpost.
