For decades, space safety rules assumed satellite reentries would stay rare. By early 2026, with over 70,000 megaconstellation spacecraft planned, that assumption has collapsed.Evelyn Hart (Indian Defence Review)

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."

When I was a freelance BBC presenter I was told I should not criticise the Royal Society when I wrote in support of Professor Dorothy Bishop’s resignation. I’m not now , so I can say that I think the society’s position on Elon Musk is troubling and wrong. Also, I’m not sure how many other fellows are there primarily because they are businessmen rather than scientists. #elonmusk #science #space #physics

#Introduction Hi #fediverse ! We’re the European Southern Observatory, and we design, build and operate ground-based telescopes.
One of them is our Extremely Large Telescope, currently under construction in #Chile. It will have a 39 m mirror, and its rotating enclosure will weigh 6100 tonnes, or about 700 mastodons!
We’re looking forward to chatting with all of you about #astronomy

“The universe is expanding, and faster now than it did in the past. Scientists don't know why, but the leading explanation is that the universe contains something that has a repulsive gravitational effect - it pushes the universe apart instead of pulling it back together. This phenomenon is called dark energy.”

Data from the Kepler #space telescope suggest there may be as many as 300 million potentially habitable planets in our galaxy alone.
We may never have evidence proving whether intelligent life is somewhere out there, but - as Carl Sagan once wrote, “If it’s just us, seems like an awful waste of space.”
This dead star is bursting back to life
It would appear that a distant star has sprung back to life after its explosive death, blasting out repeated energetic flares over a period of several months that are like nothing astronomers have seen before.

For decades, astronomers have dreamed of setting up an observatory on the far side of the Moon. I read about it as a kid. Now it's happening!
The LuSEE-Night radio telescope is under construction, and is scheduled to land on the lunar farside in 2025. It's a pathfinder for a much bigger radio telescope that would follow. newscenter.lbl.gov/2023/09/26/… #space #nasa #science

Born in 1928, Vera Rubin set her sights on Princeton, but they wouldn’t accept female grad students in astronomy. So she earned her master’s from Cornell & PhD from Georgetown.
In 1965, Rubin became the 1st woman allowed to observe at the Palomar Observatory. She went on to find evidence for the existence of dark matter.
In 1993, Rubin was awarded the National Medal of Science. But curiously, she was not awarded a Nobel Prize. themarginalian.org/2016/04/18/… #HistoryRemix #science #space #history

Our sun is big. It’s 864,000 miles or 1,392,000 km in diameter. Or 109x wider than Earth. But it’s also an average sized star.
Some stars are much bigger.
Betelgeuse, in the constellation Orion, is a red supergiant star ~700x the size of the sun.
If we replaced our sun with Betelgeuse, it would stretch past Jupiter's orbit. universe.nasa.gov/news/237/wha… #space #science

If we calculate how many grains are in a teaspoon of sand (an average) & multiply that by the amount of sand estimated on every beach & desert in the world, we get (roughly) seven quintillion, five hundred quadrillion grains of sand on Earth. npr.org/sections/krulwich/2012… #space #science
Meanwhile, there are ~70 thousand million, million, million stars in the observable universe - a figure vastly surpassing all of those grains of sand. The universe is immense, breathtaking & beyond imagination ✨
