NASA Narrows Artemis Landing Sites to 9 Key Regions

Less than two days from now, NASA’s Artemis II mission is scheduled to lift off for its historic 10-day journey around the Moon, marking the first time humans have ventured beyond Low Earth Orbit for the first time since Apollo 17 in 1972, and possibly even set new distance records for traveling beyond Earth. However, Artemis II is only scheduled as a flyby mission and will not be landing humans on the lunar surface, with this endeavor being scheduled for later missions. from Universe Today https://ift.tt/zMJ4jNQ via IFTTT

Oldest Carbon-rich Stars Open a Window to Early Cosmic Chemistry

Astronomers studying the ultra-faint dwarf galaxy Pictor II have found an extremely chemically peculiar star that contains traces of elements created by the first stars in the Universe. It's called PicII-503, a "second-generation star" that is one of the most chemically primitive stars ever found. from Universe Today https://ift.tt/qfHDLV6 via IFTTT

To Celebrate the Coming of Spring, NASA Releases Images of "Blossaming" Stellar Nurseries

Mars Was Once a World of Rain

Mars today is a frozen, barren world where liquid water can briefly appear on its surface but evaporates almost instantly in the thin atmosphere, unable to persist in any meaningful quantity. But a handful of pale, bleached rocks spotted by NASA's Perseverance rover are telling a very different story about the planet's past, one of tropical downpours, sodden landscapes, and conditions that might once have been hospitable to life. from Universe Today https://ift.tt/gmnEJpA via IFTTT

Solar Activity Could Threaten the Artemis Crew

In his blockbuster 1982 novel "Space", the writer James A. Michener wove a gripping tale of astronauts trapped on the Moon during a major solar storm. Warnings from Earth didn't come soon enough to save them from death by radiation sickness. To avoid such a tragedy happening with the Artemis crews (as with the Apollo crews of the past), NASA and the National Oceanic and Atmospheric Administration (NOAA) will monitor the Sun. If it acts up, the teams will be able to send warnings and instructions to the Artemis crews to pro tect them. from Universe Today https://ift.tt/6yUCn7K via IFTTT

New Henrietta Spectrograph to Probe Alien Atmospheres

Finding life beyond our solar system goes beyond measuring an exoplanet’s size, as rocky, Earth-sized worlds might not have the conditions for life as we know it. While exoplanets can be directly imaged by blocking their star’s glare, these images are fuzzy and lack resolution to provide enough details about the habitability. Therefore, astronomers are limited to studying an exoplanet’s atmosphere, and this has proven to be quite beneficial in teaching scientists about an exoplanet’s formation and evolution, and whether it contains the necessary ingredients for life as we know it. from Universe Today https://ift.tt/M2fX9tq via IFTTT

Bennu’s Rugged Rocks Explained by Deep Internal Cracks

Asteroids don’t get the love they deserve. They don’t get “cool points” because they’re not a planet or a potential life-harboring moon. They’re “just a bunch of rocks”. But asteroids are so much more, as they are time capsules of the early solar system that have survived billions of years untouched by weathering or plate tectonics. One of the most intriguing asteroids that has been explored is asteroid Bennu, and specifically how its physical characteristics greater differed from Earth-based observations in 2007 after NASA OSIRIS-REx spacecraft visited Bennu in 2018. from Universe Today https://ift.tt/qK4Z1AG via IFTTT

Exomoons Could Be Habitable for Billions of Years, Provided they have Hydrogen Atmospheres

Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS at LMU and the Max Planck Institute for Extraterrestrial Physics (MPE) has shown that moons around free-floating planets can keep their water oceans liquid for up to 4.3 billion years by virtue of dense hydrogen atmospheres and tidal heating—that is to say, for almost as long as Earth has existed and sufficient time for complex life to develop. from Universe Today https://ift.tt/tbXTFyA via IFTTT

Mars-Like Worlds Near M-Dwarfs May Lose Air in Millions of Years

The criteria for finding an Earth-like planet unofficially comes down to two things: water and the habitable zone. But a phenomenon known as atmospheric escape often “escapes” the minds of many astronomy fans, and it turns out that atmospheric escape is one of the key characteristics for finding an Earth-like world. Although extensive research has been conducted on how the planet Mars might have lost its atmosphere, and potentially the ability to sustain life, how would the atmosphere enveloping a Mars-like exoplanet respond to stars different from our own? from Universe Today https://ift.tt/3j20h4D via IFTTT

A Signal From Before the Stars

On 12 November 2025, LIGO picked up a gravitational wave signal that stopped astronomers in their tracks. The object that produced it was too small to be any known type of black hole, smaller in fact, than our own Sun. If confirmed, it would be something that has never been directly detected before, a primordial black hole forged in the violent chaos of the first fraction of a second after the Big Bang. Now two astrophysicists believe they can explain exactly what LIGO found and why it could crack open one of the deepest mysteries in cosmology. from Universe Today https://ift.tt/F9eUNtC via IFTTT

Hunting Moon Water With Neutrons

Water is the difference between a temporary visit and a permanent home. If humanity is serious about building a lasting presence on the Moon, finding usable ice near the lunar south pole isn't just a scientific curiosity, it's a practical necessity.

Hera Aces A Massive Engine Burn On Its Way To Didymos

In September 2022, humanity crashed a spacecraft into an asteroid - on purpose. The objective of NASA’s Double Asteroid Redirection Test (DART) was to see if we could intentionally modify the orbit of Dimorphos, the small moonlet orbiting the larger asteroid Didymos. According to all accounts, the mission worked spectacularly, but it was a one-way trip, so our ability to see what happened to the binary asteroid system has so far been limited to ground-based telescopes. That wasn’t good enough for the planetary defense community, so they planned a follow up mission called Hera, which, according to a recent press release from its operator, the European Space Agency (ESA), just successfully completed its most dramatic deep-space orbital maneuver. from Universe Today https://ift.tt/dzNPm24 via IFTTT

How Did Venus Become a Hellscape? 234,000 Simulations Reveal Four Possible Paths

Venus is increasingly becoming a touch point for our studies of the exoplanets, as missions like the James Webb Space Telescope (JWST)and the upcoming Habitable Worlds Observatory (HWO) begin to characterize rocky exoplanets around other stars. Understanding the difference between the evolutions of Venus and Earth, which ended up with such different results, is a key to understanding whether we might be looking at an Earth-analogue or a hellish landscape like Venus. A new paper by Rodolfo Garcia of the University of Washington and his colleagues, which is available in pre-print form on arXiv, simulates Venus’ 4.5 billion year evolution as part of the solar system to try to understand some of those differences. from Universe Today https://ift.tt/r10Gc3I via IFTTT

Giant Craters May Reveal if Psyche is a Lost Planetary Core

When we think of asteroids, we almost immediately think of giant rocks bouncing around like the iconic chase scene in Empire Strikes Back, and we often hear how they are remnants from the birth of the solar system. While the asteroids that comprise the Main Asteroid Belt of our solar system are not only spread far apart from each other, they are also not all made of rock. One asteroid approximately the size of the State of Massachusetts called 16 Psyche is made of metal, which planetary scientists hypothesize could be the remnants of a protoplanet’s core that didn’t build into a full-fledged planet.

The Sun’s Long-Lived Active Regions Are Massive Flare Factories—But We Don’t Know Why

Space weather is a fascinating subject, but one we still have a lot to learn about. One of the main components of it is the active regions (ARs) of the Sun. These huge concentrations of magnetic fields show up throughout the Sun’s photosphere and are the primary source of solar flares and coronal mass ejections (CMEs). They can be simple pairings of magnetic flux or huge, magnetically complex tangles that spend weeks creating massive solar storms before dissipating. But tracking the longest lived of these ARs has been a headache for solar physicists, and a recent paper by Emily Mason and Kara Kniezewski, published in The Astrophysical Journal, both dives into this tracking problem and uncovers some interesting features of the Sun’s most persistent ARs. from Universe Today https://ift.tt/QlnXgIc via IFTTT

JUICE is Planning To Do Science On Jupiter's "Minor" Moons Too

The European Space Agency’s (ESA’s) Jupiter Icy Moons Explorer (JUICE) probe is on its (very long) way to Jupiter, and will finally arrive at the King of Planets in 2031. Its primary mission is to focus on the “big three” icy moons - Ganymede, Europa, and Callisto.

Something is Changing the Small Magellanic Cloud

A strange lack of stellar orbits around the core of the Small Magellanic Cloud (SMC) mystified astronomers for decades. Not only that, but the SMC has a strange, irregular shape, and sports a tidal. Now, a team of observers led by graduate student Himansch Rathore at the University of Arizona, has tracked down the reason why the stars don't orbit. It's because the SMC crashed directly through its neighbor, the Large Magellanic Cloud (LMC), in the distant past. That huge collision disrupted stellar motions and [sent them on wildly different trajectories](https://ift.tt/cTYVN4A).

Astronomers Search for "Exotrojans" Hiding in Extreme Pulsar Systems

Greek mythology has given a name to a great many objects in our solar system. But perhaps one of the least well understood are the Trojans, named after the people of Troy featured in The Iliad. When astronomers refer to them, they are normally talking about a group of over 10,000 confirmed asteroids orbiting at the Lagrange points both in front of and behind Jupiter on its orbit around the Sun. But, more generally, astronomers can now use the term to refer to any co-orbital setup - indeed almost every planet in our solar system has Trojans, though not as many as Jupiter. Which also leads to the belief that “exotrojans” must exist around other stars. Despite our best efforts with initiatives like the TROY project, so far we have yet to find one. But a new paper published in The Astrophysical Journal by Jackson Taylor of West Virginia University and an abundance of co-authors took the hunt to one of the most extreme environments in the universe: pulsar binary systems. from Universe T...

New Study Complicates the Search for Alien Oxygen

Oxygen has been the most important gas in our search for life among the cosmos thus far. On Earth, we have it in abundance because it is produced by biological synthesis. But that might not be the case on other planets, so even if we do find a very clear high oxygen signal in the atmosphere of an exoplanet, it might not be a clear indication that life exists there. A new paper, available in pre-print on arXiv, from Margaret Turcotte Seavey and a team of researchers from institutions like the NASA Goddard Space Flight Center and Johns Hopkins University, adds some additional context to what else might be going on in those atmospheres. In particular, they note that if there’s even a little bit of water vapor, it can make a big difference in whether a lifeless rock looks like a living, thriving world. from Universe Today https://ift.tt/ebPp6Ml via IFTTT

Microscopic "Ski-Jumps" Could Shrink Spacecraft LiDAR to the Size of a Microchip

A 60-Year Old Mystery About the Moon's Magnetosphere Is Finally Solved

One particularly well known fact about the Moon is that it doesn’t have much of a magnetosphere to speak of. There’s no blanket to protect it from the solar wind ravaging its surface, blowing away its atmosphere and charging the notoriously dangerous dust particles that make up its regolith. However, scientists have also known for around 60 years that some parts of the moon do experience sudden spikes in a magnetic field - some of which are up to 10 times stronger than the background magnetization. Since their discovery, these “lunar external magnetic enhancements” (LEMEs) have puzzled researchers - what was causing them, and why did they reach so high above the lunar surface that spacecraft could see them?
