Gaia discovers our galaxy’s great wave

ESO Top News - Tue, 09/30/2025 - 8:00am

Our Milky Way galaxy never sits still: it rotates and wobbles. And now, data from the European Space Agency’s Gaia space telescope reveal that our galaxy also has a giant wave rippling outwards from its centre.

Primordial Black Holes Could Be Triggering Type Ia Supernovae

Universe Today - Mon, 09/29/2025 - 11:04pm

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.

Webb Reveals Fascinating Features in Saturn's Atmosphere

Universe Today - Mon, 09/29/2025 - 11:04pm

A study of Saturn's atmospheric structure using data from the James Webb Space Telescope (JWST) has revealed complex and mysterious features unseen before on any planet in our Solar System. The results were presented last week by Professor Tom Stallard of Northumbria University, at the EPSC-DPS2025 Joint Meeting in Helsinki.

Mars's Frozen Vortex Creates Surprise Ozone Shield

Universe Today - Mon, 09/29/2025 - 11:04pm

Mars holds a special place in my heart being the second planet I saw through a telescope. It’s probably fair to say that it’s held a special place for many as we continue to explore the fascinating world that is the red planet. Scientists studying Mars have recently uncovered a seasonal phenomenon that could change our understanding of the potential for it to support life. Their discovery, a swirling polar vortex that forms of the Martian north pole every winter.

A Herd of Tumbleweed Rovers Could Explore Mars

Universe Today - Mon, 09/29/2025 - 11:04pm

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.

Radio Astronomers Fight Back Against Satellite Interference

Universe Today - Mon, 09/29/2025 - 11:04pm

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.

Next Generation Chip Could Find Help Find Alien Life

Universe Today - Mon, 09/29/2025 - 11:04pm

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.

Curiosity Navigation

Curiosity Blog, Sols 4668-4674: Winding Our Way Along NASA’s Mars rover Curiosity acquired this image of the ridge in front of it, which it was scheduled to drive down the weekend of Sept. 27-28, 2025. To either side of the ridge are two hollows, nicknamed “Laguna Escondida” (left) and “Laguna Socompa” (right). Curiosity used its Left Navigation Camera to capture the image on Sept. 26, 2025 — Sol 4671, or Martian day 4,671 of the Mars Science Laboratory mission — at 12:54:44 UTC. NASA/JPL-Caltech

Written by Alex Innanen, Atmospheric Scientist at York University

Earth planning date: Friday, Sept. 26, 2025

We are continuing through the boxwork region, taking a twisty-turny path along the ridges (many of which are conveniently Curiosity-sized). One thing we’re keeping an eye out for is our next drill location in one of the hollows. Our most recent drive put us right in the middle of two such hollows, which we’ve named “Laguna Escondida,” and “Laguna Socompa.” As we’re keeping an eye out for a good spot to drill though, we’re still using our normal suite of instruments to continue our investigation of the boxwork structures. 

This week, we’ve had six contact science targets along the tops of the ridges, which have given MAHLI and APXS plenty to do. ChemCam and Mastcam have also been keeping busy, with several LIBS measurements from ChemCam and mosaics from both, of targets near and far. We’re not only interested in imaging the hollows to scope out our next drill site but also in continuing to investigate the structure of the ridges, and look further afield at the more distant boxwork structures and buttes around us.  

On Monday, I was on shift as the science theme lead for the environmental science theme group (ENV). We’re coming up to the end of the cloudy season in just over a week. As a result, we’ve been making the most of the clouds while they’re still here with our suite of cloud movies — the shorter suprahorizon and zenith movies, which we use to look at clouds’ properties directly overhead and just over the horizon; a survey to see how the brightness of the sky and clouds change with direction, which consists of nine cloud movies all around the rover; and the cloud altitude observation, which uses shadows cast by clouds to, as its name suggests, infer the height of the clouds. Once the cloudy season is over the number of water-ice clouds we see above Gale crater decreases dramatically, so we shelve the two longer observations for another year and just use the zenith and suprahorizon movies to monitor cloud activity. 

The end of the cloudy season does bring about the start of the dusty season though, where more dust gets lifted into the atmosphere and the lovely view of the crater rim that we’ve been enjoying gets a bit hazier. We monitor this with our regular line-of-sight and tau observations. We also tend to see more dust-lifting activity, like dust devils, which we keep an eye on with 360-degree surveys and dedicated movies. With the ever-changing atmosphere, there’s always something for ENV to do.
