Australian Telescope Finds No Signs of Alien Technology in 10 Million Star Systems
https://www.icrar.org/looking-for-et/

A radio telescope in outback Western Australia has completed the deepest and broadest search at low frequencies for alien technologies, scanning a patch of sky known to include at least 10 million stars.

Astronomers used the Murchison Widefield Array (MWA) telescope to explore hundreds of times more broadly than any previous search for extraterrestrial life.

The study, published today in Publications of the Astronomical Society of Australia, observed the sky around the Vela constellation. But in this part of the Universe at least, it appears other civilisations are elusive, if they exist. https://www.cambridge.org/core/journals/publications-of-the-astronomical-society-of-australia/article/seti-survey-of-the-vela-region-using-the-murchison-widefield-array-orders-of-magnitude-expansion-in-search-space/C175371A2383A6A03FC038D50C4D4B16/core-reader#
 



The camera core for the future Vera C. Rubin Observatory has snapped its first test photos, setting a new world record for the largest single shot by a giant digital camera.

The imaging sensor array, which comprises the focal plane for Vera Rubin's SUV-sized digital camera, snapped the 3,200-megapixel images during recent tests at the Department of Energy's (DOE) SLAC National Accelerator Laboratory in California. ("SLAC" stands for "Stanford Linear Accelerator Center," the facility's original name.)

The photos are the largest single-shot pictures ever taken, SLAC officials said — so big that showing just one of them full-size would require 378 4K ultra-high-definition TVs. The resolution is so good that a golf ball would be visible from 15 miles (25 kilometers) away.
 



In a paper released today in Nature Astronomy, Jane Greaves, astronomer at Cardiff University, and an international team of scientists announced the presence of phosphine in Venus’s atmosphere. Phosphine gas in the cloud decks of Venus | Nature Astronomy

Phosphine is considered a “biosignature”—a molecule strongly associated with the chemistry of life that has few non-life methods of production, particularly on a rocky planet like Venus. The team used two observatories—the James Clerk Maxwell Telescope (JCMT) in Hawaii and the Atacama Large Millimeter Array (ALMA) in Chile—to verify their detection.

The implications are massive: there could be life in Venus’ atmosphere. This may sound implausible, but there are regions of Venus’ upper atmosphere that are remarkably temperate and relatively hospitable. For decades there has been the hypothesis that, against the odds, microbial life forms could be floating around the planet. This detection is one piece of evidence in support of that hypothesis, but we are far from proving the existence of life.

Predictably, the news about this announcement has generated lots of breathless news coverage and claims about confirmed Venusian life on social media. These are inaccurate characterizations of the paper released today. What can we as non-scientists do to responsibly interpret this claim and not contribute to misinformation?

Let’s consider several pieces of context for evaluating the reliability—and implications—of this claim.

"So far we've done everything we can, which is go through all the things that it isn't. We've thought of every possible mechanism, plausible or implausible, that could make phosphine and we cannot come up with any."— Clara Sousa-Silva, an author of the study and researcher at MIT, to Axios
