As an amateur #astronomer and #astrophotographer, I often use parsecs as a unit of measure.
Turns out a certain well known #astrophysicist hates them.
And for good reason.

New #Hubble images may solve the case of a disappearing exoplanet
A fading dust cloud hints that the once-seen #exoplanet #FomalhautB was never a #planet
“What’s cool about this paper is that for the first time ever we are seeing one of these disks change over time,” says #astrophysicist Tim Pearce. That’s unusual in the field of protoplanetary disks, where scientists usually observe structures that “basically look the same for a human lifetime.”

#OnThisDay Happy Birthday Swiss #Astrophysicist Michel Mayor (1942). He discovered 51 Pegasi b, the first extrasolar planet orbiting a sun-like star, 51 Pegasi and won the 2019 Nobel Prize in Physics along with Jim Peebles and Didier Queloz.
Birth Anniversary of "Smokin' Joe" Joe Frazier (1944) - undisputed heavyweight champion from 1970 to 1973, and as an amateur won a gold medal at the 1964 Summer Olympics.

Day 4 of #artAdventCalendar is my portrait of British-born, American #astrophysicist Margaret Burbidge (1919-2020) who was one of the people instrumental in building our understanding of stellar nucleosynthesis, how nuclei are produced in stars & you and I are all stardust! She was the 1st author of a monumental scientific paper Synthesis of the Elements in Stars, which became known as B2FH from the initials of its authors: 🧵

This radiation can only be observed when the star is pointed towards us; so, like the light from a lighthouse, it appears to pulse at a precise frequency. She had been working with her supervisor Hewish & others to construct a radio telescope 🧵1/

#Starlink is burning up one or two #satellites a day in #Earth’s atmosphere
#KesslerSyndrome is bad; atmospheric incineration may be worse, says #astrophysicist Jonathan McDowell
Many of #China's proposed satellites are going to be in #LEO at the same altitude as Starlink, McDowell noted a number are planning to fly above 1000km. Were something to go wrong up there, "we're probably screwed."... "That higher altitude means the atmosphere won't drag them down for centuries"

Scientists Find a Quadruple Star System in Our Cosmic Backyard
First, the #astronomers identified what they believed was a lone #browndwarf orbiting a bright single #star. Further investigation revealed that the brown dwarf was actually two. After submitting a paper about the discovery, Dr. Zhang said, they realized that the bright companion was a pair of #stars, too.
“I like to call this a double-double,” said Adam Burgasser, an #astrophysicist.

🚨NEWS: James #Webb #Space Telescope confirms that there is something seriously wrong with our understanding of the #universe, and reveals that there is an unknown #physics.
Excuse me, I'm not an #astrophysicist, but I've maintained for years that the prevailing narratives about the Big Bang and the universe's evolution are largely speculative. Simply stating that the calculations are mathematically consistent and the theory functions doesn't constitute proof.

The #printerSolstice2425 prompt this week is iron, so after talking last week about how certain numbers of nucleons are "magic" as you grow increasingly large nuclei, now we're talking about how you do that: how you grow nuclei from a single proton to the largest naturally-occurring transuranic elements. British-born, American #astrophysicist Margaret Burbidge (1919-2020) is 1 of the people instrumental in building our understanding 🧵

Making my #linocut portraits of #astrophysicist Margaret Burbidge (1919-2020) for #PrinterSolstice2425 prompt: iron! It’s about how most of you and I are stardust, made of elements built in stars through stellar nucleosynthesis. Supergiant stars build elements up to iron through nuclear fusion. In a famous paper known as B2FH, first-authored by Margaret Burbidge, they reviewed everything known about stellar 🧵1/2

Working on my next #linocut for #printersolstice2425 - last week we talked about how some numbers of nucleons (neutrons and protons) are “magic” so sometimes if you add another the binding energy is lower than the last, so the resulting nuclei are more common and stable. This week is about how you do that…. How you add nucleons to nuclei and grow heavier elements.
Anyone recognize this #astrophysicist ?

#astrophysicist #MattODowd expresses concerns that "physics is stalled" — see our toot from 28 Aug 2024. Is our best out-of-the-box thinking and experimentation being impeded by #cognitive #biases? The animated video targets safety issues in the workplace, but, is scientific creativity also suffering from a reluctance to deviate from, or institutional pressure to continue in, one's familiar lane, when the future resides in other lanes of inquiry? How can one know? #PhilosophyOfScience

"#Astrophysicists in the #NanoGrav collaboration have found evidence for HUGE #gravitationalwaves that could be due to merging supermassive #blackholes. This was all possible due to pulsar timing arrays which triangulate the positions of pulsars across our galaxy to work out of the distances between them change due to a passing light year long #gravitationalwave!"
