Hey astronomers, I have a question.
Let's say I'm on a planet in a solar system. Does it matter to my living conditions if I'm in a neat, undisturbed galaxy or in one that is messed up by interaction with neighbours?

The hard steps theory suggests human-level intelligence is a cosmic rarity, requiring improbable evolutionary leaps that may have occurred only once on Earth. However, some transitions may appear singular due to lost evidence or a priority effect, where the first successful group blocks competitors. While intelligence might still be uncommon, reasons could range from self-annihilation of civilizations to simple lack of interest in space exploration.

SpaceX filed an application with the US Federal Communications Commission for a megaconstellation of up to one million #satellites to power data centres in #space.
The proposal envisions satellites operating between 500 and 2,000 kilometres in low Earth #orbit. Some of the orbits are designed for near-constant exposure to sunlight.
The approval process for these satellites focuses almost entirely on the limited technical info companies have to submit to regulators.
Cultural, spiritual, and most #environmental impacts aren’t taken into account – but they should be.
At this scale of growth, the night #sky will change permanently and globally for generations to come.
In 2021, astronomers estimated that in less than a decade, 1 in every 15 points of light in the night sky would be a moving satellite. That estimate only included the 65 000 #megaconstellation satellites proposed at the time.
Once deployed at a scale of millions, the impacts on the night sky may not be easily reversed.

European agree – our security is on the right track and the momentum is building.
The mandate for EU action is definitive:
🔹 74% support for defence investment.
🔹 52% trust the EU to strengthen security.
🔹 53% see Space Policy as a key security tool.
68% of citizens believe their country is under threat. Europe is ready to step up.
Too wound up to go to bed, so I just sent lots of emails to people hoping that they'll spread the word and get lots more people to write comments to the FCC telling them that orbital data centres and sunlight-as-a-service are incredibly stupid, dangerous ideas and should never be launched.

I don't think it'll actually make a big difference. But I do think it's incredibly important that the official record shows how many opposed this.

@EUCommission What does the #EU do against the real threat of #spaceDebris and #space #pollution by US corporations like #SpaceX & Co? The space is not a military room, it is at first nature and our vulnerable atmosphere! We only have this one planet!

"To Fly Free in Space" is #NASA #astronomy picture of the day #APOD for February 15, 2026. This iconic image was taken 42 years ago in Feb 1984 on STS-41B Space Shuttle Challenger as astronaut Bruce McCandless II tested the untethered spacesuit called MMU (Manned Maneuvering Unit), with thrusters making it and him a spacecraft. Though the MMU only had enough propellant to do work around the shuttle and its payloads. #space #history

"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."

Does anyone feel like the #billionaires are actually systematically culling the global population?
#Vaccine denial
#climatechange ( #drought #flood #heatwave #hurricane )
Cutting #humanitarian #aid
#armed thugs targeting people
#militarized borders that prevent people from moving to safer places
#AI #datacenters (destroying #employment)
#space (million satellites?)
It all seems to be accelerating. Are we really at the beginning of global genocide?
On this day in 1990, the Voyager 1 space probe took a photo of our planet from approximately 6 billion kilometers (3.7 billion miles) away.
"Commissioned by NASA and resulting from the advocacy of astronomer and author Carl Sagan, the photograph was interpreted in Sagan's 1994 book, Pale Blue Dot, as representing humanity's minuscule and ephemeral place amidst the cosmos."
