Sharper Black Hole Images Could Put Einstein’s Gravity to the Test: New Study Maps What Future Telescopes Must See (7 Nov 2025)

Brighter Than 10 Trillion Suns: Record Black Hole Flare 10 Billion Light‑Years Away

Date: November 7, 2025 Key points What happened—and why this one is different A Caltech‑led team reports an extraordinary flare from the supermassive black hole in AGN J2245+3743, first seen rising dramatically in 2018 and now recognized as a record‑setter for both luminosity and distance. At peak, it shone with the light of ~10 trillion suns, unmistakably towering above the AGN’s usual variability. California Institute of Technology+1 The peer‑reviewed study, published November 4, 2025 in Nature Astronomy, quantifies just how extreme the event is: the source brightened by more than a factor of 40, radiating a cumulative ~10⁵⁴ ergs—on par

Sharper Black Hole Images Could Put Einstein’s Gravity to the Test: New Study Maps What Future Telescopes Must See (7 Nov 2025)

Published: November 7, 2025 What happened today A wave of coverage on Friday highlighted a new Nature Astronomy study that sets a concrete target for the next generation of black hole images: if upcoming telescopes can reach percent‑level fidelity, they could tell Einstein’s black holes apart from a range of look‑alikes predicted by alternative theories of gravity. The paper—published November 5—uses advanced simulations to show that when the mismatch between images exceeds roughly 2–5%, future instruments should be able to rule out many non‑Einstein models. Nature Today’s recaps emphasize what this means in practice: sharper “shadow” images—the dark silhouette encircled

Blue Origin to Launch NASA’s Twin ESCAPADE Mars Probes on Nov. 9: Time, Livestream, Mission Goals, and What Happens Next

Blue Origin to Launch NASA’s Twin ESCAPADE Mars Probes on Nov. 9: Time, Livestream, Mission Goals, and What Happens Next

Published: November 7, 2025 Key facts at a glance What’s launching and why it matters Blue Origin’s New Glenn is slated to lift off Nov. 9 carrying ESCAPADE—Escape and Plasma Acceleration and Dynamics Explorers—two identical NASA satellites designed to explain how Mars lost most of its atmosphere and water. The probes will make coordinated measurements to build a 3D, time‑varying picture of Mars’ upper atmosphere and magnetic environment, something a single spacecraft can’t do. It’s NASA’s first dual‑satellite mission to another planet, marking a milestone for low‑cost planetary science. Space Each spacecraft carries electrostatic analyzers (UC Berkeley) to track charged

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)

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 indicates heat

Shenzhou‑20: China Delays Astronauts’ Return After Suspected Space‑Debris Strike — Latest on Tiangong (Nov 7, 2025)

Shenzhou‑20: China Delays Astronauts’ Return After Suspected Space‑Debris Strike — Latest on Tiangong (Nov 7, 2025)

Published: November 7, 2025 Summary What happened China’s human‑spaceflight agency said the Shenzhou‑20 return mission, originally scheduled for Wednesday, was postponed due to a suspected impact from tiny orbital debris on the crew capsule. The agency added that “impact analysis and risk assessment” are underway to determine next steps. Xinhua News Independent outlets and space publications corroborated the delay and the debris suspicion, noting that the capsule has remained docked while engineers evaluate its condition. As of Friday, Nov. 7, officials have not provided a revised landing plan. Reuters+1 Who is aboard Tiangong The outgoing Shenzhou‑20 crew consists of Commander

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

Comet 3I/ATLAS News Roundup (Nov. 6, 2025): China’s Mars Orbiter Images the Interstellar Visitor, JWST Chemistry Update, and How to See It

Comet 3I/ATLAS news roundup — November 6, 2025 Today’s big development: China’s Tianwen‑1 Mars orbiter captured and released new images of the interstellar comet 3I/ATLAS (also cataloged as C/2025 N1), taken from roughly 30 million km away during the comet’s October 3 pass near Mars. China’s state outlets say the sequence shows clear cometary features and marks one of the closest probe‑based looks at the object to date. The observation doubles as a technology pathfinder for China’s upcoming Tianwen‑2 mission. State Council of China+2Xinhua News+2 What the Tianwen‑1 images add Context: ESA’s TGO produced the closest European look on Oct.

‘Yeast Survives Mars’ & ESA’s ‘Protein Out of Thin Air’: How Biology Is Rewriting the Mars Menu — and What It Means for Investors

‘Yeast Survives Mars’ & ESA’s ‘Protein Out of Thin Air’: How Biology Is Rewriting the Mars Menu — and What It Means for Investors

Key facts (updated Nov 5, 2025): The story: Biology is moving from thought experiment to flight plan Europe’s HOBI‑WAN pilot (Hydrogen‑Oxidizing Bacteria in Weightlessness As a source of Nutrition) is ESA’s clearest sign yet that microbial food production will be part of living off‑Earth. The agency says the demonstrator feeds a bacterial culture with stored gases (H₂, O₂, CO₂) to produce Solein, a protein‑rich powder that needs “neither farmland nor sunlight.” The ISS testbed will ride in a standard locker and includes safety‑critical gas‑injection cartridges because hydrogen/oxygen handling in microgravity must be fail‑safe. The first eight months build and validate

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

Interstellar Comet 3I/ATLAS Stuns Scientists with Surprising Bright Outburst and Ancient Origins

A Visitor From Beyond the Solar System In July 2025, astronomers discovered something extraordinary: a dim, fuzzy comet hurtling toward the inner solar system on a path not bound to the Sun. Follow-up observations confirmed this object – now named 3I/ATLAS (for the ATLAS survey that found it) – was on a hyperbolic trajectory, meaning it came from interstellar space and would soon depart forever science.nasa.gov en.wikipedia.org. The “3I” designation marks it as the third interstellar object ever observed, after the asteroid-like 1I/ʻOumuamua and comet 2I/Borisov science.nasa.gov. Unlike ʻOumuamua (which was small, oddly shaped, and showed no coma), 3I/ATLAS immediately
