Scott Manley recently flew up to Hat Creek and visited the Allen Telescope Array. He was joined by Dr. Alex Pollak, who is in charge of Operations at the facility and has extensive knowledge of the hardware, from antennas to the data center and the power required to support it.

When NASA’s Dawn mission first captured images of the dwarf planet Ceres, bright reflective spots on its surface sparked worldwide fascination. Although the mission concluded in 2018, its data continues to reshape our understanding of this small but complex world.
In a recent episode of SETI Live, host Beth Johnson spoke with Dr. Sam Courville, postdoctoral researcher at ASU and lead author of a new Science Advances paper on the potential past habitability of Ceres.
My MIL passed away in August. She was about to turn 105 and participated in many of the No Kings events in Mt. Kisco, NY. She was a plasma physicist, grew up with Einstein as a family friend and is the reason why NY water is clean and frakking is banned. Her obituary is frankly, amazing. #STEM #science #activism #climatechange https://www.therecorder.org/post/marian-rose-104-bedford-resident-scientist-and-longtime-activist
Next #SETILive: When We Find Life
TODAY, 18 September, 11:00 am PDT
What happens after we discover life beyond Earth? The question is no longer “if,” but “when”—and how humanity responds could shape our future. Host and planetary astronomer Franck Marchis welcomes Martin Dominik, one of the authors of a new white paper on the societal, political, and philosophical challenges we’ll face once alien life is confirmed.

Under the tropical skies of Puerto Rico, a new observatory joined the LaserSETI Network, expanding the SETI Institute’s ability to search for technosignatures. Bringing cutting-edge instruments to an island with an already astronomical history, the project will scan the heavens for fleeting flashes of light. With this installation, Puerto Rico now plays a central role in optical SETI efforts.

Millions of Texans have already come down with long #COVID symptoms, and many more could be at risk in the future if we don't make changes. For this @TexasObserver magazine feature, I interviewed both sufferers and medical experts about solutions we can take: https://www.texasobserver.org/long-covid-texas-clearing-the-air/

Thirty years after the first exoplanets were discovered, hundreds of additional exoplanets have been identified within the “habitable zone,” a place where liquid water and maybe even life may exist. The MIT Press Reader asks, could a self-sustaining starship carry humans to distant worlds? https://flip.it/0q093h

The durability of forever chemicals comes from replacing hydrogen atoms with fluorine atoms in an eight-carbon chain. The strong carbon-fluorine bond does not break down easily. Why that’s a problem for our health on this week’s Big Picture Science.

#Trump #EPA tells scientists to stop publishing studies, employees say
Staff from the EPA’s Office of #Water were summoned to a “town hall” meeting this week & told to pause the publication of most #research, pending a review.

When I post about #science & #history, I tend to highlight the trailblazers we don’t usually read or hear about in #HistoryRemix.
But tonight I want to share this beautifully composed piece about Nikola Tesla.
While his inventions are legendary, you may not know how Tesla’s OCD shaped his approach to science & ultimately led to his world-changing ideas. It also left him isolated & alone. But he still experienced deep connection by caring for birds. https://nautil.us/teslas-pigeon-460446/
Only three humans have ever witnessed an eclipse of the Sun by the *Earth*. It happened while the Apollo 12 crew was returning home from the Moon, on November 21, 1969.
Fortunately, the astronauts filmed the moment so you can share in the experience.

#ICYMI: Are we close to discovering life beyond Earth? Dr. Martin Dominik isn't certain, but he thinks we should be prepared to handle the consequences of finding that life. He spoke with Dr. Franck Marchis in this week's #SETILive. Watch the full interview: https://youtube.com/live/cULB0k2Cb7s
How do we find new trans-Neptunian objects, given that they are small and distant? Astronomer Dr. Rosemary E. Pike explains the necessary observations taken before, during, and after the expected place in the sky. Listen to the latest #SETILive #podcast: https://feeds.libsyn.com/462636/rss

"Hypotheses, treated as mere poetic fancies in one age, scouted as scientific absurdities in the next — preparatory only to their being altogether forgotten — have often, when least expected, received confirmation from indirect channels, and, at length, become finally adopted as tenets, deducible from the sober exercise of induction."
Michael Faraday #BOTD in 1791.
British scientist Rosalind Franklin died #OTD in 1958.
Her most famous contribution to science came from her X-ray diffraction images of DNA, particularly Photo 51, which provided crucial evidence for the double helix structure of DNA. Her photo was shared without her knowledge with J. Watson & F. Crick, who used it as a basis for their model of DNA's structure. Their work overshadowed her contribution, & she was not fully recognized for her role until after her death.
As a reporter, I've followed the science of gender-affirming care from before the current political moment. I have always committed to following the evidence, whether I like it or don't like it.
Today on Assigned, I've published a piece by a freelancer who did her master's on the informed consent model of gender affirming treatment. She wrote us a digest version.
The narrative is the narrative. The evidence tells another story. #trans #science #news #journalism

The #EPA Has Done Nearly Everything It Can to Clean Up This Town. It Hasn’t Worked.
==
Despite years of air monitoring, inspections and millions in penalties for petrochemical plants, the air in Calvert City, #Kentucky, remains polluted.
The EPA’s inability to fix it is an indictment of the laws governing clean air, experts say.

There is something seriously wrong with our understanding of the universe. Scientists using the James Webb and Hubble space telescopes have triple-checked and confirmed that depending on where we look, the universe is expanding at bafflingly different rates. Live Science explains more, including how scientists are ruling out a measurement error as the cause of the “Hubble Tension.” https://flip.it/VDvM6g

I've spent yesterday and today talking to researchers across the globe trying to understand the hantavirus outbreak aboard the cruise ship MV Hondius.
My story is here (and some threaded thoughts coming):

French astronomer Charles Messier died #OTD in 1817.
He is best known for his catalog, the Messier Catalog (contains 110 objects), which lists various astronomical objects, including nebulae, star clusters, and galaxies. Messier was primarily interested in comet hunting, and his catalog was created to help him and other astronomers differentiate between permanent celestial objects and comets, which could easily be mistaken for new discoveries.
#OTD in 1885.
Louis Pasteur successfully tests his vaccine against rabies on Joseph Meister, a boy who was bitten by a rabid dog. This vaccine bwas produced by growing the virus in rabbits, and then weakening it by drying the affected nerve tissue. The vaccine had been tested in 50 dogs before its first human trial. The treatment's success laid the foundations for the manufacture of many other vaccines.
Dutch mathematician, physicist, engineer, astronomer, & inventor who is regarded as a key figure in the Scientific Revolution Christiaan Huygens was born #OTD in 1629.
He developed the wave theory of light, proposing that light propagates as a wave rather than a stream of particles, which was a revolutionary idea at the time. Huygens also invented the pendulum clock, which greatly improved timekeeping accuracy and became widely used in scientific experiments and everyday life.
Belgian chemist, industrialist and philanthropist Ernest Solvay was born #OTD in 1838.
He is best known for his pioneering work in the chemical industry and for the establishment of the Solvay process for the manufacture of soda ash (sodium carbonate). In 1911, he began a series of important conferences in physics, known as the Solvay Conferences, whose participants included Max Planck, Ernest Rutherford, Maria Skłodowska-Curie, Henri Poincaré, and Albert Einstein.
