I guess you stop worrying about whether what you're doing will poke the bear, once you're convinced the bear is coming for you anyway

Russian president Vladimir #Putin warned that his country would respond if #Nato began to bolster the military infrastructure of #Sweden and #Finland which have both decided to join the military alliance https://euobserver.com/tickers/154951
I should add that the two black hole shadows are similar sizes on the sky. It’s just that the M87 one is further awa. Sgr A* is much more challenging though because its smaller physical size means it varies much more quickly. Like trying to make a sharp picture from a movie of a running child in the dark, as they said in the press conference… A tour de force of interferometry! Amazing work
Beautiful demo from a few years back of how tiny these black hole shadows are, compared to what the Hubble Space Telescope can do

Just for fun, let's compare the pixel scale of the Hubble Space Telescope's WFC3 camera with the Event Horizon Telescope image released today. #enhance

Simply astonishing black hole shadow image by the @EHtelescope@twitter.com showing not just how they compare to solar system scales, but also how much more challenging SgrA* is compared to M87's black hole. Huge progress and clearly a promise of so much more to come! VERY exciting!

Just read an article about online identify theft so did a reverse image search on my picture and WHAT THE FUCK GOOGLE
I hear Warhol's Marilyn Monroe painting was sold for record-breaking $195m, and I'm reminded of Men In Black 3 https://www.youtube.com/watch?v=1MbvNXZL5f0
Can't stop gazing in delight at this Spitzer -> Webb animation - also downloadable at https://www.esa.int/ESA_Multimedia/Images/2022/05/MIRI_s_sharper_view_hints_at_new_possibilities_for_science
RT @ESA_Webb@twitter.com
Compare the same target seen by Spitzer & in Webb’s calibration images! Webb’s image, taken by #MIRI, features light from “polycyclic aromatic hydrocarbons." These molecules of carbon & hydrogen help us better understand the gas that exists between stars. 📷@NASA@twitter.com/@esa / CSA/STScI

If true, this is a genuinely astonishing psychological projection & lack of self-reflection by the prime minister
RT @JAHeale@twitter.com
Sunday Times claims Boris Johnson personally "despises" his opposite number. An ally says: "He genuinely does not like Keir. He sees this man as part of a privileged, metropolitan, narrow-minded elite uncomfortable with the raw instincts of the vast majority of British people."

The Conservatives have been routed in local elections throughout the country, while they try to deflect from #PartyGate and years of insouciant lawbreaking, and here are the headlines. This is why we can’t have nice things (via @TmorrowsPapers@twitter.com)

Science writers, take note. Here is how the Hartford Courant reported the discovery that Mars has two moons (August 1877).
