—SpaceNews.com: “Key Antenna in NASA’s Deep Space Network Damaged“

One of the largest antennas in NASA’s Deep Space Network was damaged in September and may be out of service for an extended period, further straining the system. NASA’s Jet Propulsion Laboratory confirmed Nov. 10 that the 70-meter antenna at the Deep Space Network (DSN) site in Goldstone, California, has been offline since Sept. 16, with no timetable for its return to service.

—University of Geneva: “Dark Matter Does Not Defy Gravity, Study Suggests“

Does dark matter follow the same laws as ordinary matter? The mystery of this invisible and hypothetical component of our universe—which neither emits nor reflects light—remains unsolved. A team involving members from the University of Geneva (UNIGE) set out to determine whether, on a cosmological scale, this matter behaves like ordinary matter or whether other forces come into play. Their findings, published in Nature Communications, suggest a similar behavior, while leaving open the possibility of an as-yet-unknown interaction. This breakthrough sheds a little more light on the properties of this elusive matter, which is five times more abundant than ordinary matter.

—University of Oxford: “Saturn’s Icy Moon May Host a Stable Ocean Fit for Life, New Study Finds“

A new study led by researchers from Oxford University and Southwest Research Institute and the Planetary Science Institute in Tucson, Arizona has provided the first evidence of significant heat flow at Enceladus’ north pole, overturning previous assumptions that heat loss was confined to its active south pole. This finding confirms that the icy moon is emitting far more heat than would be expected if it were simply a passive body, strengthening the case that it could support life.

—The Economic Times: “NASA Confirms Earth Has a Second Moon, And It Will Stay With Us Until 2083“

Earth has received a new cosmic partner, a small asteroid designated as 2025 PN7. NASA confirmed this week that the object, initially found by the University of Hawaii, qualifies as a “quasi-moon” , an uncommon type of celestial body that moves almost similarly in sync with Earth. While not a real moon, it has a similar orbit surrounding the Sun, seeming to shadow our planet as it travels through space. Researchers estimate the asteroid measures 18 to 36 meters wide, approximately the height of a small building, making it small by cosmic standards but noteworthy for Earth’s extended neighborhood.

—Sky&Telescope: “New Study Identifies Organic Molecules Spewing from Saturn’s Icy Moon Enceladus“

Twenty years after the Cassini spacecraft discovered an ocean under the icy surface of Saturn’s moon Enceladus, a new study of previously collected data hints at a much better chance for habitability. The change comes from recording how a plume of ice grains hit Cassini just minutes after it erupted from the moon. The close encounter exposed organic compounds not previously seen on Enceladus.

—Utrecht University: “Mysterious Gullies on Mars Appear to Have Been Dug, But by Whom or What?“

Did life really exist on Mars after all? Unfortunately, there is no conclusive evidence for this yet. Nevertheless, it would seem that some form of life was the driving force behind the mysterious Martian dune gullies. Earth scientist Dr Lonneke Roelofs from Utrecht University has investigated how these gullies were formed. In a test setup, she observed that blocks of CO2 ice ‘dug’ these gullies in a unique way. “It felt like I was watching the sandworms in the film Dune.”

—Physics World: “NASA Criticized Over its Management of $3.3bn Dragonfly Mission to Titan“

An internal audit has slammed NASA over its handling of the Dragonfly mission to Saturn’s largest moon, Titan. The drone-like rotorcraft, which is designed to land on and gather samples from Titan, has been hit by a two-year delay, with costs surging by $1bn to $3.3bn. NASA now envisions a launch date of July 2028 with Dragonfly arriving at Titan in 2034.

—USAToday: “Do Rockets Still Launch During a Government Shutdown? How NASA Could Feel the Effects“

NASA is far from immune to the effects of a looming government shutdown if congressional leaders fail to reach an agreement before midnight Oct. 1 to prevent one. At stake for the U.S. space agency if the federal government grinds to a halt? The progress of many of its science missions and access to its public outreach arm. NASA’s contingency plan for a shutdown, outlined in a guide from 2018, emphasizes that only “activities which are necessary to prevent harm to life or property” would be exempt from ceasing operations during a shutdown.

—Earth Sky: “‘Invisible’ Asteroids Near Venus: A New Danger to Earth?“

Astronomers across the globe are dedicated to identifying the near-Earth asteroids that could one day impact our planet. But there might be a group of potentially dangerous nearby asteroids that have remained invisible to astronomers so far. On September 24, 2025, an international team of researchers at the São Paulo State University (UNESP) in Brazil said that a group of asteroids sharing Venus’ orbit could have remained undetected so far due to their location in the sky. And they could pose a threat to Earth within a few thousand years.

—New Scientist: “Did Something Just Hit Saturn? Astronomers Are Racing to Find Out“

Something may have just hit Saturn – and, if so, an amateur astronomer could hold the key to confirming the event, which would be the first ever recorded on the gas giant. About seven asteroids or comets are estimated to impact Saturn every year, but no such event has ever been caught on camera. Now, NASA employee and amateur astronomer Mario Rana has recorded images that appear to show just that.

—Astronomy.com: “Astronomers Race to Learn More About Third Interstellar Visitor“

Astronomers have spotted an object from outside our solar system bolting toward the Sun at around 150,000 mph (240,000 km/h). The big, frozen ball of ice and dust presents a rare chance to study an object that formed around an alien solar system, and potentially much earlier in the Milky Way’s history. The object named 3I/ATLAS — “3I” because it’s the third interstellar object detected so far, and “ATLAS” in honor of the system of telescopes that revealed it, the Asteroid Terrestrial-impact Last Alert System. Because the object is also showing tentative signs of cometary activity, it has also been designated C/2025 N1 (ATLAS).

—Universe Today: “Old Hubble Space Telescope Photos Unlock the Secret of a Rogue Planet“

Astronomers have achieved a first in exoplanet hunting by using the Hubble Space Telescope images to investigate a mysterious event that could reveal the existence of a “rogue planet” drifting through space without a host star. The discovery centers on a brief astronomical phenomenon with the catchy name OGLE-2023-BLG-0524, detected in May 2023 by ground-based telescopes. The event lasted just eight hours and was caused by gravitational microlensing, an effect predicted by Einstein where a massive object acts like a magnifying glass in space, briefly brightening the light from a more distant object as it passes in front.

—NASA: “NASA Releases its Spinoff 2025 Publication“

The work NASA conducts in space leads to ongoing innovations benefiting people on Earth. Some of these latest technologies, which have been successfully transferred from NASA to the commercial sector, are featured in the latest edition of Spinoff 2025 publication now available online. The publication features more than 40 commercial infusions of NASA technologies, including research originated at NASA’s Glenn Research Center in Cleveland.

—Cleveland.com: “NASA Urged to Move Headquarters to Ohio as D.C. Lease Expires“

When the National Aeronautics and Space Administration‘s lease on its current Washington, D.C. headquarters expires in 2028, Ohio members of Congress want NASA to move its headquarters to Ohio. In a Tuesday letter to Vice President JD Vance and President Donald Trump’s nominee to be NASA Administrator, Jared Isaacman, Ohio Congress members argue that bringing the headquarters of the nearly 18,000 employee agency to their state would align with broader government efforts to decentralize federal agencies and reinvigorate parts of the country outside Washington.

—USA Today: “Moon King: Astronomers Discover 128 New Moons Orbiting Saturn. Here’s What We Know.“

Astronomers have discovered 128 new moons orbiting Saturn, further solidifying the planet as the “moon king” of our solar system. Astronomers from Taiwan, Canada, France and the U.S. announced the discovery on Tuesday. The findings push Saturn’s moon count to 274, towering over the previous record-holder Jupiter, which has 95 moons. The recent discovery points to what astronomers have speculated for decades, that Saturn’s rings were caused by a massive collision about 100 million years ago, researcher Mike Alexandersen, an astronomer at the Center of Astrophysics, told USA TODAY. A collision of such size could explain the small moons that orbit Saturn.
