Starlink Is Dropping From the Sky Again and Again. Scientists Warn Earth Is Already Feeling the Effects

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.

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 giant metal frame of a dome takes up most of the picture frame, contrasting with the brown hills and a thin horizontal line of blue sky in the background. The dome's frame is not yet fully covered in the middle, so the dark brown landscape behind it shows. The big opening in the dome's roof shows the interior, still a construction site with a structure of white beams. In front of the big building is one red crane, taller than the dome.

The European Space Agency's Euclid space telescope is assembling the largest 3D map of the universe ever made.

The first section is now complete. Take a look at what happens when you zoom in...

The huge mosaic released by ESA’s Euclid space telescope on 15 October 2024 accounts for 1% of the wide survey that Euclid will capture over six years. The location and actual size of the mosaic on the Southern Sky is shown in yellow.
This mosaic made by ESA’s Euclid space telescopes contains 260 observations collected between 25 March and 8 April 2024. This is 1% of the wide survey that Euclid will capture during six years. In just two weeks, Euclid covered 132 square degrees of the Southern Sky, more than 500 times the area of the full Moon as seen from Earth. The full mosaic is 208 gigapixels.
This image shows an area of the mosaic released by ESA’s Euclid space telescope on 15 October 2024. The area is zoomed in twelve times compared to the large mosaic. In the middle left, spiral galaxy NGC 2188 is visible edge-on at a distance of 25 million light-years. In the top right corner, galaxy cluster Abell 3381 is now clearly noticeable, 678 million light-years away from us.
This image shows an area of the mosaic released by ESA’s Euclid space telescope on 15 October 2024. The area is zoomed in 150 times compared to the large mosaic. On the left of the image, Euclid captured two galaxies (called ESO 364-G035 and G036) that are interacting with each other, 420 million light-years from us. On the right of the image, galaxy cluster Abell 3381 is visible, 678 million light-years away from us.

Award-winning photographer Josh Dury captured this stunning picture of the Milky Way over Easter Island and some of its famous Maoi. From his Instagram post: "A truly unforgettable night from one of the darkest places on Earth, surrounded by a place and a community that is close to my heart. One of the most powerful, emotional moments of my life."

“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

🚨 🚨 NEW JWST IMAGE 🚨 🚨

#science #space

webbtelescope.org/contents/med…

From JWST: At the center is a thin horizontal orange cloud known as Herbig-Haro 46/47 that is uneven with rounded ends, and tilted from bottom left to top right. It takes up about two-thirds of the length of this angle, but is thin at the opposite angle. At its center is a red-and-pink star with prominent, eight-pointed diffraction spikes. It has a central yellow-white blob. The orange lobe to the left is fatter. Just off the edge is a tiny red arc that curves in the opposite direction. The right lobe is thinner, and ends in a smaller orange semi-circle that has a faint purple outline. Just off the edge of this lobe is a slightly smaller orange sponge-like blob. A thin, undulating blue line runs from the central stars through the right lobe. A delicate, semi-transparent blue cloud known as a nebula drifts toward the top of the image and peters out toward the left of the frame, but toward the right and bottom, it ends in a soft ridge set off in a translucent orange. The background is filled with stars and galaxies.

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
