One way of studying and understanding distant, hard-to-reach locations elsewhere in the Solar System is to find analogues of them here on Earth. For example, deserts and lava fields are often used to understand aspects of the Martian surface. In new research, scientists collected samples from natural geysers in the Utah desert to try to understand the Solar System's icy ocean moons. from Universe Today https://ift.tt/pgE7kHN via IFTTT

Searching for life beyond Earth has rapidly advanced in recent years. However, directly imaging an exoplanet and all their incredible features remain elusive given the literal astronomical distances from Earth. Therefore, astronomers have settled by exploring exoplanet atmospheres for signatures of life, also called biosignatures. This is currently conducted by analyzing the starlight that passes through an exoplanet’s atmosphere, known as spectroscopy, as it passes in front of its star, also called a transit. But improvements continue to be made to better explore exoplanet atmospheres, specifically cleaning up messy data. from Universe Today https://ift.tt/iz6st1S via IFTTT

Our solar system hosts almost 900 known moons, with more than 400 orbiting the eight planets while the remaining orbit dwarf planets, asteroids, and Trans-Neptunian Objects (TNOs). Of these, only a handful are targets for astrobiology and could potentially support life as we know it, including Jupiter’s moons Europa and Ganymede, and Saturn’s moon Titan and Enceladus. While these moons orbit two of the largest planets in our solar system, what about moons orbiting giant exoplanets, also called exomoons? But, to find life on exomoons, scientists need to find exomoons to begin with. from Universe Today https://ift.tt/SL0scXg via IFTTT

If humans want to live in space, whether on spacecraft or the surface of Mars, one of the first problems to solve is that of water for drinking, hygiene, and life-sustaining plants. Even bringing water to the International Space Station (ISS) in low Earth orbit costs on the order of tens of thousands of dollars. Thus, finding efficient, durable, and trustworthy ways to source and reuse water in space is a clear necessity for long-term habitation there. from Universe Today https://ift.tt/XvFhVuw via IFTTT

The early Universe was a busy place. As the infant cosmos exanded, that epoch saw the massive first stars forming, along with protogalaxies. It turns out those extremely massive early stars were stirring up chemical changes in the first globular clusters, as well.

Lunar dust remains one of the biggest challenges for a long-term human presence on the Moon. Its jagged, clingy nature makes it naturally stick to everything from solar panels to the inside of human lungs. And while we have some methods of dealing with it, there is still plenty of experimentation to do here on Earth before we use any such system in the lunar environment. A new paper in Acta Astronautica from Francesco Pacelli and Alvaro Romero-Calvo of Georgia Tech and their co-authors describes two types of flexible Electrodynamic Dust Shields (EDSs) that could one day be used in such an environment. from Universe Today https://ift.tt/DUxhvrK via IFTTT

Using local resources will be key to any mission to either the Moon or Mars - in large part because of how expensive it is to bring those resources up from Earth to our newest outposts. But Mars in particular has one local resource that has long been thought of as a negative - perchlorates. These chemicals, which are toxic to almost all life, make up between 0.5-1% of Martian soil, and have long been thought to be a hindrance rather than a help to our colonization efforts for the new planet. But a new paper from researchers at the Indian Institute of Science and the University of Florida shows that, when making the bricks that will build the outpost, perchlorates actually help. from Universe Today https://ift.tt/7jzaEOW via IFTTT

A complex web of interrelated factors make Earth a life-supporting planet, and some of those factors are chemical.

Scientists have discovered a revolutionary way to measure Earth's radiation budget by observing our planet from the Moon. A team of astronomers have revealed that lunar observations capture Earth as a complete disk, filtering out local weather noise and revealing planet scale radiation patterns dominated by spherical harmonic functions, effectively creating a unique "fingerprint" of Earth's outgoing radiation. This Moon based perspective solves fundamental limitations of satellite observations, which struggle to achieve both temporal continuity and spatial consistency, offering a new tool for understanding global climate change with unprecedented clarity. from Universe Today https://ift.tt/7cwdQuZ via IFTTT

New research has revealed that Mars’ most recent volcanoes weren’t formed by simple, one off eruptions as scientists previously thought.

On 14 January, 2025, two colliding black holes sent the clearest gravitational wave signal ever recorded rippling across the universe to Earth’s detectors. This remarkably crisp signal, designated GW250114, has allowed physicists to conduct the most stringent test yet of Einstein’s general relativity by measuring multiple “tones” from the collision. The wave passed the test with flying colours, but researchers remain optimistic that future detections might finally reveal where Einstein’s century old theory breaks down, potentially offering the first glimpses of quantum gravity. from Universe Today https://ift.tt/7jGtKbc via IFTTT

Every so often (in geologic time) Earth's magnetic field does a flip. The north and south magnetic poles gradually trade places in a phenomenon called a geomagnetic reversal. Scientists long thought this happened every ten thousand years or so. However, new evidence from deep ocean cores show that at least two ancient reversals didn't follow that script. One took about 18,000 years to flip and the other took 70,000 years. Such lengthy time lapses could have seriously affected Earth's atmospheric chemistry, climate, and evolution of life forms during the Eocene period of geologic history. from Universe Today https://ift.tt/tma0SPZ via IFTTT

Free-Floating Planets, or as they are more commonly known, Rogue Planets, wander interstellar space completely alone. Saying there might be a lot of them is a bit of an understatement.

Mars’ water disappeared somewhere, but scientists have been disagreeing for years about where exactly it went. Data from rovers like Perseverance and Curiosity, along with orbiting satellites such as the Mars Reconnaissance Orbiter and ExoMars have shown that Mars used to be a wet world with an active hydrodynamic cycle. Obviously it isn’t anymore, but where did all the water go?

Why are planets rarely found orbiting a pair of stars? UC Berkeley and American University of Beirut physicists find that general relativity makes the orbit of a tight binary pair precess. As the orbit shrinks because of tidal effects, the precesion increases. Eventually the precession matches the orbital precession of any circumbinary planet, creating a resonance that makes the planet’s orbit wildly eccentric. The planet either gets expelled from the system or is engulfed by one of the stars. from Universe Today https://ift.tt/rvnt89V via IFTTT

Origami and space exploration might not seem like they have much in common, but the traditional paper-folding technique solves one massive problem for space exploration missions - volume. Satellites and probes that launch in rocket housings are constrained by very restrictive requirements about their physical size, and options for assembling larger structures in orbit are limited to say the least. Anything that can fold up like an origami structure and then expand out to reach a fully functional size is welcome in the space community, and a new paper published in Communications Engineering by Xin Ning of the University of Illinois Urbana-Champaign (UIUC) and his lab describes a novel use case for the idea - electromagnetic waveguides. from Universe Today https://ift.tt/rueNPYW via IFTTT
