Want to help discover a black hole? Our scientists are calling on amateur astronomers to join the Black Hole Hunters project. No telescope needed - just a phone, tablet or laptop and your curiosity. 🔗 tr.ee/Pu83kY @spacesouthcentral.bsky.social @ukspaceagency.bsky.social @esa.int
A young woman with long brown hair smiles next to a large black telescope on a silver tripod. She is wearing blue jeans and a black T-shirt with the logo "University of Southampton" printed in white on the front left. A black hole against the Milky Way, shown as a dark circle surrounded by warped rings of starlight. Brown, gold and pink clouds of gas and dust and distant stars fill the background.

🧵On @thenewsagents.co.uk yesterday, school closures and the lab leak theory were offered as two examples of legitimate questions that were hard to ask. Both have in fact been asked constantly since 2020. But here's a thread on why I think they were wrong and dangerous on school closures 1/12

I'm absolutely devastated for colleagues at Jodrell Bank who found out this morning that funding for the UK's e-MERLIN radio telescope array will be terminated. This is a short-sighted move, to save a tiny fraction of the overall UK science budget. #SaveJodrellBank 🔭🧪 www.bbc.co.uk/news/article...

It was inevitable, wasn't it🙄 Of course the Telegraph would run with something like this👇 So let's remove some of the rose-tinted spectacles and also look at some of that data comparing 1976 with modern heat waves Because the 1976 nostalgia porn is wearing a bit thin at this stage 🧵1/23

One of the more compelling data visualizations produced in recent years is the following representation of measles incidence from 1928 to 2003 by state produced by the Wall Street Journal graphics team:

Heatmap chart titled “Measles” showing reported measles cases by U.S. state over time from roughly 1930 to 2010. States are listed in rows on the left (e.g., Alaska, Arkansas, California, Connecticut, etc.), and years run along the horizontal axis. Each small square represents a state-year, colored by number of cases using a scale from light blue (near 0) through green and yellow to orange and red (highest, up to about 4,000 cases). A vertical black line around 1963 is labeled “Vaccine introduced.” Before this line, many states show frequent yellow/orange/red squares, indicating large outbreaks. After the line, the grid shifts mostly to very light blue with only occasional darker squares, indicating a sharp and sustained drop in measles cases following vaccine introduction.

In the two years after its release, many prominent data journalists, designers, and developers have analyzed/applauded the design decisions in the chart, which urge the reader to its take-home message: the introduction of the measles vaccine drastically reduced the incidence of the virus.

Revolutionary new space telescope @4most-eu.bsky.social has captured its first data from the universe. Our scientists are part of the team behind the super-scope and say it’ll reveal how galaxies and black holes formed. Read more 👉 tr.ee/ba4NEs
The VISTA 4MOST, a large, intricate astronomical device, housed inside an industrial facility. The structure features a prominent circular component with visible wiring and metal framework, supported by a sturdy blue frame with stairs and a raised platform for access.The VISTA mountain top observatory stands on rocky terrain under a clear night sky, with the Milky Way stretching across and a bright planet shining above.

Sarah’s rules of looking for life with only chemical signatures: 1) the smaller the molecule(s) the more likely they can also be produced by abiotic processes 2) one molecule, if it can be produced by any abiotic process, will never be enough to definitively claim detection of life
