Hidden Heat at Enceladus’ North Pole Bolsters Case for Life: Cassini Data Show Stable Ocean in New Study (Nov. 7, 2025)

Hidden Heat at Enceladus’ North Pole Bolsters Case for Life: Cassini Data Show Stable Ocean in New Study (Nov. 7, 2025)

Meta description: A new analysis of NASA’s Cassini data finds excess heat at Enceladus’ north pole, balancing previously known heat loss in the south. The results, published Nov. 7, 2025 in Science Advances, suggest the icy moon’s global ocean has remained stable over geologic time—strengthening its habitability. Science+3SciTechDaily+3Space+3 Publish date: November 7, 2025 What’s new A peer‑reviewed study released today in Science Advances reports the first clear evidence of endogenic (internal) heat flow at Enceladus’ north pole. Until now, direct heat loss had only been measured at the south pole, where Cassini discovered dramatic plumes in 2005. The new result

Interstellar Comet 3I/ATLAS: A Visitor from Beyond the Solar System

Comet 3I/ATLAS today (6 Nov 2025): China’s Mars orbiter snaps new photos as the interstellar visitor turns bluer and shows puzzling acceleration

Updated: 6 November 2025 — A rapid, reader-friendly briefing on the third interstellar object ever found, tailored for Google News & Discover. At a glance — what’s new on Nov 5–6 China’s Tianwen‑1 just gave us a rare Mars‑orbit look at 3I/ATLAS China’s space agency says the Tianwen‑1 Mars orbiter used its high‑resolution camera to observe 3I/ATLAS during the object’s close pass by Mars (early October), when the spacecraft was ~30 million km from the comet—one of the nearest probe‑based looks so far. The agency released images and a brief 30‑second sequence showing the comet’s motion, adding that the observation

Alien Probe or Cosmic Relic? Interstellar Comet 3I/ATLAS Baffles Scientists (updated 27.10.2025)

Ancient Interstellar Comet 3I/ATLAS Nears Sun – A 10-Billion-Year Visitor Ignites Awe and Alien Speculation

Discovery and Designation Comet 3I/ATLAS was discovered on July 1, 2025 by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey telescope at Río Hurtado, Chile esa.int. ATLAS – a NASA-funded sky survey designed to spot incoming asteroids – detected a faint magnitude ~18 object moving against the starry background ras.ac.uk. Initially catalogued as C/2025 N1 (ATLAS) under comet naming conventions, the object raised immediate excitement because its orbit did not appear bound to the Sun ts2.tech. Within days, astronomers determined the new comet was on a highly hyperbolic trajectory, not a closed ellipse like ordinary comets. In August 2025 the International

SpaceX’s Starship Triumph Sparks Moon Race 2.0 with China – Stocks Take Off

NASA’s Epic Week: Moon Rocket Ready, Mars Life Clue, and an Interstellar Visitor

Artemis on the Fast Track – and a New Moon Race NASA’s Moon program reached a major milestone this week: engineers at Kennedy Space Center finished stacking the Space Launch System (SLS) rocket for Artemis 2, placing the Orion crew capsule (nicknamed “Integrity”) atop the booster space.com. “The towering rocket…has come together,” NASA announced, after hoisting Orion onto SLS inside the Vehicle Assembly Building space.com. This completed rocket – set to launch four astronauts around the Moon – was even exempted from the ongoing federal shutdown, underscoring Artemis 2’s high priority space.com. The mission is targeting February 2026 for liftoff, which would mark

Hidden ‘Planet-Killer’ Asteroid Found in Sun’s Glare Exposes Dangerous Blind Spot

Hidden ‘Planet-Killer’ Asteroid Found in Sun’s Glare Exposes Dangerous Blind Spot

A “Twilight” Asteroid Breaks Speed Records Astronomers are buzzing about 2025 SC79, a newfound asteroid that’s zipping around the sun at near-record pace. Scott S. Sheppard, an astronomer at Carnegie Science, first spotted the object on September 27 using the Blanco 4-meter telescope in Chile carnegiescience.edu carnegiescience.edu. What he found was astonishing: an asteroid orbiting the sun in just 128 days, making it the second-fastest asteroid ever recorded space.com. Only one known asteroid orbits faster – 2021 PH27, a 1-km rock discovered by Sheppard in 2021 that races around the sun in 113 days livescience.com. Even Mercury, the innermost planet, takes

SpaceX Moon Mission in Jeopardy: Musk Clashes with Trump Official After NASA Opens Lander Bids

NASA’s acting chief Sean Duffy has announced he will open the Artemis III lunar-lander contract to competition after SpaceX’s delays ts2.tech. Competing firms like Jeff Bezos’s Blue Origin and a Lockheed Martin–led team are now eyeing the first crewed Moon mission, slated for 2028 to beat China’s 2030 lunar goal ts2.tech reuters.com. SpaceX’s Starship has made progress (recent test flights met key objectives ts2.tech ts2.tech) but the program is still behind earlier schedules kesq.com ts2.tech.

SpaceX’s Moon Mission in Jeopardy as NASA Opens Artemis Contract to Rivals

NASA Reopens Moon Lander Contract Amid SpaceX Delays NASA’s surprise move to reopen the Artemis III lunar lander contract marks a dramatic shift in the U.S. return-to-the-Moon effort. Acting NASA Administrator Sean Duffy – who also serves as U.S. Transportation Secretary – revealed on Monday that NASA will no longer rely exclusively on SpaceX for the planned Moon landing mission. “I’m in the process of opening that contract up,” Duffy said, explaining that SpaceX’s development schedule has slipped too much reuters.com.

Rare Interstellar Comet 3I/ATLAS – a 10-Billion-Year-Old Time Capsule – Flies Past Mars

Rare Interstellar Comet 3I/ATLAS – a 10-Billion-Year-Old Time Capsule – Flies Past Mars

A Visitor from Beyond the Solar System Humanity has waited a long time to study a comet from another star – and suddenly, within a decade, we’ve had three. 3I/ATLAS (officially 3I/2025 A1) is the latest of these rare interstellar interlopers. It was first detected moving through the outer Solar System in June 2025 with an exceptionally eccentric orbit. Follow-up observations quickly confirmed what its speed and trajectory implied: this object was not bound to the Sun’s gravity ts2.tech. By July 2025, the Minor Planet Center designated it the third interstellar object ever found ts2.tech. Like its predecessors – the cigar-shaped 1I/‘Oumuamua and cometary 2I/Borisov –

Interstellar Comet 3I/ATLAS: A Visitor from Beyond the Solar System

Rare Cosmic Flyby: Interstellar Comet 3I/Atlas to Zip Past Mars as Spacecraft Brace for Close-Up Study

Looking Ahead: What 3I/Atlas Can Teach Us This week’s close approach marks just the beginning of an intensive observation campaign. Once 3I/Atlas dives behind the Sun in late October, Earth-based telescopes will lose it, but Mars and Jupiter satellites (and later telescopes on Earth in December) will continue the story. During perihelion and its outbound journey past Jupiter (in early 2026) the comet should reveal its secrets – or at least its usual cometary face. As one commentator notes, watching 3I/Atlas in this active phase “will give some of the clearest insights yet into the mystery of interstellar comets” space.com.
