"Earth's impact scars reveal the history of asteroid strikes on our planet" by BBC @skyatnightmag - The Moon shows an uneroded view of the cosmic firing line the Earth also sits in. But Earth's atmosphere burns up small asteroids. Geologic forces immediately begin a slow process of erasing craters from view. But if you look, there are hundreds that we know of. https://www.skyatnightmagazine.com/earth-from-space/earth-impact-scars #LowFlyingRocks #ImpactCrater #asteroid #astronomy #geology #planetary #science #space

"'It took our breath away' – Mars rover finds strange polygon features in the Red Planet's rusty dirt" by BBC @skyatnightmag - #NASA #CuriosityRover got a 360° panorama showing polygon shapes like mud cracks in all directions around it. But Mars doesn't currently have surface water. This makes opportunities for research how they could have formed. https://www.skyatnightmagazine.com/news/mars-rover-polygon-features #Mars #planetary #geology #space

Ahoy there any #asteroid #meteor #planetary scientists.
How many tons (kg) of space rock enters the atmosphere per year? And can one work out what the proportion of various elements is in terms of what goes into the atmosphere?
Curious to compare numbers with proposed mega sat constellations.
Eg SpaceXs AI constellation will likely bring down 1.5 million tons of assorted exotic elements into the atmosphere every year... seems... a lot.

' Those who shout loudest against #Green policies and visions for a #sustainable egalitarian future are those few with the most to lose.'

'The case for #voting Green
'I’m not a member of the Green #Party, but they're getting my #vote. Here’s why. ...'THE GREENS HAVE two core messages. They’re both simple enough to express, but they can be difficult to explain.
'The first is that we have to change. We’re living beyond what’s called “#planetary boundaries”, which is a way of saying we are using up #Earth’s finite #resources, destroying #biodiversity and making the #planet inhospitable to life.
'There’s no “fix the economy and then we’ll sort out the planet”. The way we’re “fixing the economy” is the problem...
'The second message is that the problems we face have a common cause. It’s the super-rich. Not “people who are well off”, but a tiny #elite: #Elon #Musk and all who travel with him, the #tycoons of the #fossil-fuel #industry, the #financiers who enable them. They have created the #climate crisis, the menaces of social #media, the funnel that sucks #wealth upwards even while they pretend it trickles down.
'The #oligarchs and #techbros are not trying to solve the #world’s problems, although they have the resources to do so. They’re causing them so they can make #money from them.'
'Green policies turn those core messages into action plans. #Energy reform, to leave fossil fuels in the ground and introduce rooftop #solar with #batteries at massive scale. Urban networks of #electrified public #transport, #cycling and walking that are so frequent, reliable, safe and cheap they offer genuinely better #travel options for many people much of the time. #Conservation strategies to clean up our #waterways. A proper commitment to social #housing.
'And tax #reform, targeting the super-rich and offering a #tax cut to 96% of us...'

"Pathfinder on Mars" is #NASA #astronomy picture of the day #APOD - 29 years ago on July 4, 1997, NASA's Pathfinder landed on #Mars carrying the first successful Mars rover, called Sojourner. NASA had previously successfully landed 2 non-rover probes Viking 1 in July 1976 & Viking 2 in September 1976. The Soviet Union attempted 2 rover landings on Mars in 1971 and never tried again: one destroyed on impact and one landed then lost communication. https://apod.nasa.gov/apod/ap260704.html #space #planetary #science

"NASA’s HiRISE Captures Perseverance Marking a Milestone on Mars" by #NASA #Science - #Perseverance rover was imaged from orbit as it completed a very slow marathon (26.2mi / 42.2 km) in 1890 sols on #Mars, or 5 years 4 months for its operators on Earth. Movement is slow when movement isn't the main point. It makes short autonomous drives and then stays studying that spot under remote control for a while. https://science.nasa.gov/photojournal/nasas-hirise-captures-perseverance-marking-a-milestone-on-mars/ #Mars #space #planetary #geology

Of course, a discussion among politicians won't get #Pluto reclassified back as a planet. Scientists & astronomers decide criteria for a planet. Pluto is either in or out of that definition.
I wonder what criteria that would define Pluto as a planet would not also apply to our Moon, a.k.a. Luna. Are we ready for Earth🌎/Luna🌗 to be officially a binary planet system? After trying to be the center of our universe for all of history, could we take that step? #astronomy #planetary #science

"Pluto-like world’s thin atmosphere poses a mystery" by @cosmiclog / @alanboyle - A thin atmosphere may have been observed around a #KuiperBelt object a quarter Pluto's size. As the minor planet crossed in front of a star, telescopes saw light go out and come back slowly rather than instantly. And since Alan is author of "The Case for Pluto" book, he mentions a recent public discussion among politicians about reclassifying Pluto as a planet. https://cosmiclog.com/2026/05/08/pluto-like-worlds-thin-atmosphere-poses-a-mystery/ #astronomy #planetary #science

What The Soviets Found On Venus
- interesting vid to watch
- learn about Soviet determination
- unreal atmospheric pressures
- temperatures higher than an oven in the atmosphere
- braking systems for probes in water like behaving heavy Venus atmosphere
- Venera 13 had a mic onboard!
- Venus sounds horrifying (at least to my little cousin whose listening in as I make this toot) ;)
- they had sent 14 probes at least to Venus

🌏 Why are only a few #planets suitable for life? And why is Earth one of them?
Dr. Rob Spaargaren, together with his international team of astronomers, answers these questions in a new paper.
It may have consequences for the search for life elsewhere.🔎
