Constraining Proxima b’s Atmosphere, Orbit, and Albedo with RISTRETTO

What new methods can be employed to help astronomers distinguish the light from an exoplanet and its host star so the former’s atmosphere can be better explored? This is what a recent study accepted to Astronomy & Astrophysics hopes to address as an international team of researchers investigated how a novel and proposed telescopic instrument that could be capable of characterizing exoplanet atmospheres in new and exciting ways. This study has the potential to help scientists develop novel tools for examining exoplanets and whether they could possess life as we know it, or even as we don’t know it. from Universe Today https://ift.tt/qJ7CE6A via IFTTT

NASA is Looking to Launch Artemis II by February

NASA announced that Artemis II, the first crewed mission to the Moon since the Apollo Era, will launch by February 2026. The crew has named their spacecraft "Integrity" to honor the efforts those working tirelessly to realize NASA's long-awaited return to the Moon. from Universe Today https://ift.tt/7ZdyKeg via IFTTT

Primordial Black Holes Could Be Triggering Type Ia Supernovae

A new article published in The Astrophysical Journal explores a new theory of how Type Ia supernovae, the powerful stellar explosions that astronomers use to measure distances across the universe, might be triggered. Traditionally, these supernovae occur when a white dwarf star explodes after interacting with a companion star. But this explanation has limitations, leaving open questions about how these events line up with the consistent patterns astronomers actually observe. from Universe Today https://ift.tt/cU8owNr via IFTTT

A Herd of Tumbleweed Rovers Could Explore Mars

Tumbleweeds offer iconic visual depictions of desolate landscapes. Though typically associated with the American West, the most common type of tumbleweed actually originated in Europe, and is known scientifically as salsola targus, or more commonly as Russian thistle. So its only fitting that a team led by European scientists has some up with an idea based on the tumbleweed’s unique properties that could one day have groups of them exploring Mars. from Universe Today https://ift.tt/NwSQ2FB via IFTTT

Radio Astronomers Fight Back Against Satellite Interference

Visual observations have, over the years had to battle light pollution, weather, aircraft and even satellite constellations. Radio observations have until recently, been reasonably well protected however in their attempt to preserve the “quiet skies” a team of radio astronomers have secured a significant victory. For the first time, they've joined forces with the International Special Committee on Radio Interference, a committee that sets global standards for preventing electronic interference. from Universe Today https://ift.tt/O47vGMu via IFTTT

Next Generation Chip Could Find Help Find Alien Life

Are we alone in the universe? It’s a question that has plagued us since the ancient Greeks posed it for the first time in the 5th century and since then we have tried all manner of ways to reach out to our alien cousins….if they exist. We have fixed golden plaques to space probes, beamed messages out from radio telescopes and in 2012 even sent 10,000 ‘X’ (formerly twitter) messages out to three star systems with the hashtag #ChasingUFOs! A new tool has been developed, rather mundane compared to these other examples, which is no bigger than a soft drink can and could detect signs of life on alien worlds with unprecedented precision. from Universe Today https://ift.tt/EC07x3Y via IFTTT

The JWST Searches For Stars In A Glowing Gas Cloud

The JWST examined the most vigorous star-forming region in the entire galaxy. It's called Sagittarius B2, and while astronomers have studied it in detail, no other telescope reveals its details the way the JWST can. from Universe Today https://ift.tt/TulgAwD via IFTTT
