AI Thread Summary
Recent discussions around the detection of the earliest stars highlight skepticism from experts in the field. Ned Wright, an astronomy professor at UCLA, questions the validity of the findings, suggesting that the methods used to isolate the radiation from ancient stars are flawed. He believes that the observed signals may actually be residuals from nearby sources rather than evidence of ancient stellar activity. While the discovery is intriguing, experts advise caution in interpreting the results. The debate emphasizes the complexities involved in astrophysical measurements and the need for further validation.

From that report as New Wright said
Ned Wright, an astronomy professor at UCLA, was more doubtful. He argued that the process of removing the radiation contribution of other stars is too imprecise to make the team's conclusions valid, and that the measurement it saw is not the signal of ancient stars.

"I'm very skeptical of this result. I think it's wrong," he said. "I think what they're seeing is incompletely subtracted residuals from nearby sources."

Very exciting but it would be wise to be cautious.

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.
