SETI Institute Senior Research Scientist Janice Bishop and University of Massachusetts Engineering Professor Mario Parente analyzed orbital hyperspectral images from the Compact Imaging Spectrometer for Mars (CRISM) aboard the Mars Reconnaissance Orbiter, producing a detailed mineral map at the tens-of-meters scale of the crater documenting deposits of clays and carbonates signaling abundant water on ancient Mars.

On the occasion of the International Annual Meeting of the German Astronomical Society, where a joint effort is happening right now to connect existing #fediverse accounts and to invite more members of the community to participate, here is a starter pack of accounts with a relation to Astronomy in Germany:
Are you all already following each other? Did you just get started and want to ask to be included, too? Would you like to suggest further additions to the starter pack? Are you discovering accounts in the list whose introductions should get boosted around a lot more? Are astronomy aficionados out there finding this list useful?

So cool. If you zoom in on the upper right, you see a little crescent. That's the Martian moon Phobos.
Zoom in again and you'll see a star next to Phobos. That's Earth! That's home.
Seen from Mars by NASA's Curiosity rover.

Featuring prominently on our season's greetings card: the first images of the Sun's south pole 🛰️ ☀️
During its flyby of the Sun at the end of March this year, the Solar Orbiter space probe had its first clear view of our star's poles. Solar Orbiter's trajectory has recently been tilted 17 degrees relative to the Sun's equator, allowing measurements from this unique perspective for the first time. As the new observations impressively show, the magnetic field at the poles is currently in a state of turmoil.
In addition to the images of the sun's south pole taken by the Solar Orbiter spacecraft, the past year has brought us many other highlights: exciting scientific results and important awards. Read more at https://www.mps.mpg.de/en/season-s-greetings-2025

“We’re Too Close to the Debris”: How SpaceX Rockets Put Passenger Planes at Risk
---
The FAA predicted Elon Musk’s Starship would cause “minor or minimal” disruption. Then the rockets exploded twice in three months over busy airspace. Flight data reveals how many planes scrambled to protect passengers and avoid burning debris.

Astronomers sure do conjure up a lot of spooky images when they look out into deep space. A short Halloween thread:
Let's start with the Cosmic Bat Nebula (LDN 43).

Three Chinese astronauts who have been living on China's Tiangong space station since April 24 were set to return to Earth Wednesday when a piece of suspected “space junk” struck their return capsule — just hours ahead of departure. Looks like they’re going to be there for a while. Read more from @LiveScience:
Fascinating #documentary on the #Challenger space shuttle #disaster. Apparently #NASA withheld quite a bit of #information from the #public for decades.
While it was true the rubber O rings failed due to subfreezing temperatures, NASA ignored engineers warnings and proceeded with the launch. What isn't true is the #astronauts vaporizing due to the #explosion. Withheld #evidence showed not only were they aware, they activated #emergency air tanks and were passengers trapped in a cabin on a #terrifying high speed freefall which slammed into the ocean.

Enter the Dragon 🐉🥋
Here it is – my new JWST image of the young protostellar outflow system in Cassiopeia called HH288, aka The Dragon Jet.
We discovered it in the 1990s & the NASA/ESA/CSA JWST reveals stunning new detail, including several new jets crossing the main dragon 🙂👍

"For two decades, spacefaring nations have operated under a simple rule: any satellite sent into orbit must have a less than one in 10,000 chance of injuring someone on the ground. The rule was written when a few dozen objects reentered the atmosphere each year. By early 2026, with more than 9,000 #Starlink satellites in orbit and filings for constellations totaling over 70,000 spacecraft, that arithmetic no longer holds."

Yes, you may be killed by falling human made space junk, but the odds remain small(ish) that will occur. The (almost inevitable) #KesslerSyndrome may also prevent future #space flights if all those #satellites in Low Earth Orbit start colliding, creating countless debris.
However, we *ALL* have to worry about the ‘chemical problem’ being created by SpaceX et al in the upper atmosphere. I have been banging on about this for a while and the attached article summarises the science in an easy to understand way - I have pasted the bit about the ‘chemical problem’ below because we *ALL* need to understand what the billionaires are doing to the planet while we are watching.

Debris on the ground attracts immediate attention, but atmospheric scientists are tracking a slower process with potentially larger consequences. When satellites vaporize in the mesosphere, 50 to 80 kilometers above Earth, they release clouds of vaporized metals that condense into aerosol particles. Those particles descend into the stratosphere, where Earth’s protective ozone layer resides.
Aluminum is the element of greatest concern. Upon reentry, aluminum oxidizes into aluminum oxide nanoparticles. A single 250 kilogram satellite generates roughly 30 kilograms of these particles. Unlike chlorofluorocarbons, which directly destroy ozone, aluminum oxide acts as a catalyst. One particle can facilitate chemical reactions that destroy thousands of ozone molecules over decades without being consumed.
Researchers from the University of Southern California’s Department of Astronautical Engineering documented an eightfold increase in atmospheric aluminum oxides between 2016 and 2022, directly correlating with the proliferation of satellite constellations, a finding reported in detail by CNET. In 2022 alone, reentering satellites released an estimated 41.7 metric tons of aluminum, approximately 30 percent more than the natural input from micrometeoroids.
Projections based on current deployment schedules suggest annual aluminum oxide emissions could reach 360 metric tons, a 646 percent increase over natural background levels, according to research highlighted by Popular Mechanics. Because these particles take 20 to 30 years to descend into the ozone layer, the atmospheric chemistry of today’s satellite fleet will not manifest as measurable ozone loss until the 2040s. By then, the upper atmosphere could already be saturated with catalysts.
NASA high altitude sampling flights over Alaska in 2023 detected the signature of this process. At approximately 60,000 feet, instruments found that 10 percent of stratospheric sulfuric acid particles larger than 120 nanometers contained aluminum and other metals traceable to spacecraft reentries, according to data presented at the American Astronomical Society meeting that year. The atmosphere now bears a permanent chemical marker of human activity in space.
