Moonquakes Will Pose Risks To Long-term Lunar Base Structures

Our Moon is a seismically active world and its long history of quakes could affect the safety of permanent base structures there. That's one conclusion from a study of quakes along the Lee-Lincoln fault in the Taurus-Littrow valley where the Apollo 17 astronauts landed in 1972. “The global distribution of young thrust faults like the Lee-Lincoln fault, their potential to be still active and the potential to form new thrust faults from ongoing contraction should be considered when planning the location and assessing stability of permanent outposts on the Moon,” said Smithsonian senior scientist emeritus Thomas R. Watters, lead author of the paper. from Universe Today https://ift.tt/cetYhyx via IFTTT

Researchers Simulate What a Black Hole "Shadow" Look Like

Supercomputer simulations are helping scientists sharpen their understanding of the environment beyond a black hole’s "shadow," material just outside its event horizon. from Universe Today https://ift.tt/aQbLxDs via IFTTT

The JWST Shows Us That TRAPPIST-1d Is Not As Earth-Like As We Hoped

The exoplanet TRAPPIST-1 d intrigues astronomers looking for possibly habitable worlds beyond our Solar System because it is similar in size to Earth, rocky, and resides in an area around its star where liquid water on its surface is theoretically possible. But according to a new study using data from the NASA/ESA/CSA James Webb Space Telescope, it does not have an Earth-like atmosphere. from Universe Today https://ift.tt/vEkT9Bz via IFTTT

A Simple Instrument Could Find Martian DNA - If It Exists

Mars still holds the promise of being one of the first places in the solar system humanity will colonize. However, if there was evolutionarily distinct, extant life on the planet, it might sway the heart of even the most ardent Mars colonization fans. So astrobiologists are in a race against time to try to determine whether or not such life exists, before the entire planet becomes an analogue of the Earth’s biosphere, if only unintentionally, and only a shadow of the ones that exists here. A new paper from the Christopher Temby and Jan Spacek of the Agnostic Life Finder (ALF) team discusses one of the most promising ways to prove definitively that life exists on the Red Planet - finding polyelectrolyte polymers - in other words, DNA. from Universe Today https://ift.tt/OFL16Bk via IFTTT

The Vibrational Lives of Black Holes

When black holes are disrupted by things like infalling matter or gravitational waves, they vibrate like a bell struck with a clapper. The vibrations decay over time as the black hole returns to an equilibrium state. Astrophysicists can measure these vibrations to learn more about the black hole. from Universe Today https://ift.tt/ArX6mf1 via IFTTT

When Dwarfs Dance, Do Galaxies Merge?

New research shows how the 'dancing' behaviour of dwarf satellite galaxies can predict mergers between their hosts. A distant pair of galaxies is undergoing the same type of merger that Milky Way/Andromeda will undergo. Can the behaviour of their dwarf satellites tell astronomers what will happen when the MW and Andromeda merge? from Universe Today https://ift.tt/ADvQJf3 via IFTTT

NASA's Juno Spacecraft Could Intercept 3I/ATLAS as it Approaches Jupiter

arXiv:2507.21402v1 Announce Type: new Abstract: The interstellar object 3I/ATLAS is expected to arrive at a distance of $53.56(\pm 0.45)$ million ${\rm km}$ ($0.358\pm 0.003$~au) from Jupiter on March 16, 2026. We show that applying a total thrust $\Delta$V of $2.6755}$ to lower perijove on September 9, 2025 and then execute a Jupiter Oberth Maneuver, can bring the Juno spacecraft from its orbit around Jupiter to intercept the path of 3I/ATLAS on March 14, 2026.
