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

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

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

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

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.

Engineers at the University of Wisconsin-Madison uncovered a critical flaw in how lunar and Martian rovers are tested on Earth. Simulations revealed that test results have been misleading for decades because researchers only adjusted rover weight to simulate low gravity—but ignored how Earth’s gravity affects the terrain itself. Using a powerful simulation tool called Chrono, the team showed that sandy surfaces behave very differently on the Moon, where they’re fluffier and less supportive. from Universe Today https://ift.tt/jTCGxWQ via IFTTT

A team of astronomers using the James Webb Space Telescope have achieved a breakthrough in understanding TRAPPIST-1, the famous red dwarf star hosting seven Earth sized planets.

Lucy is already well on its way to Jupiter’s Trojan asteroids. But that doesn't mean that it can’t make some improvements to its trajectory along the way. A new paper suggests it might be possible to nudge Lucy into a slightly different orbit, allowing it to pass an as-yet-undiscovered asteroid sometime during its exploration of the L5 cloud of Trojan around Jupiter. If completed, it could lend an entirely new research target to Lucy’s repertoire and further define the differences between the two Trojan clouds. from Universe Today https://ift.tt/5xoCPa3 via IFTTT

What if we could send a probe smaller than a paperclip, yes a paperclip to visit a black hole? It sounds impossible, but one scientist believes this extraordinary mission could become reality within our lifetimes. Astrophysicist Cosimo Bambi has outlined a bold plan to launch microscopic spacecraft toward the nearest black hole, potentially revolutionising our understanding of physics and Einstein's theory of general relativity.

An international team of astronomers led by The University of Texas at Austin’s Cosmic Frontier Center has confirmed the most distant black hole ever observed. Located at the center of the galaxy CAPERS-LRD-z9, this black hole existed 13.3 billion years ago, just 500 million years after the Big Bang.

Venus, often called Earth's twin, remains one of the most mysterious planets in our Solar System.

3D printing is going to be a critical technology in space exploration, both for its ability to create almost any object, but also because it can utilize in-situ resources, at least in part. However, the more of those space resources are used in a print, the more the mechanical properties change from that on Earth, leading to problems with tensile or compressive strength. But a new paper from researchers at Concordia University hit a new milestone of how much lunar regolith can be used in a mixed feedstock for additive manufacturing, making it possible to use even more locally sourced material, and saving more launch cost, than ever before. from Universe Today https://ift.tt/NPmsJXc via IFTTT

The resources tucked away in asteroids promise to provide the building blocks of humanity’s expansion into space. However, accessing those resources can prove tricky. There’s the engineering challenge of landing a spacecraft on one of the low-gravity targets and essentially dismantling it while still remaining attached to it. But there’s also a challenge in finding ones that make economic sense to do that to, both in terms of the amount of material they contain as well as the ease of getting to them from Earth. A much easier solution might be right under our noses, according to a new paper from Jayanth Chennamangalam and his co-authors - mine the remnants of asteroids that hit the Moon. from Universe Today https://ift.tt/l4Pynip via IFTTT

Deep cracks stretching hundreds of kilometers across the Martian surface might look like simple scars from ancient impacts, but they're actually windows into a surprisingly dynamic planetary history.

Astronauts exploring the Moon will need all the help they can get, and scientists have spent lots of time and plenty of money coming up with different systems to do so.

Many objects in the outer Solar System contain large amounts of water ice, leading to a thick icy shell surrounding an ocean of liquid water. This water behaves like lava on Earth, reshaping their surfaces through a process called cryovolcanism.
