For decades, radio telescopes have been eavesdropping on the cosmos, hoping to detect alien signals. Now NASA is expanding the scope of that search: For the first time, it has awarded a grant to a SETI project that will search for technosignatures other than radio signals. “Our imagination is limited by what we have accomplished as a technological civilization,” says Abraham Loeb, the Frank B. Baird, Jr., Professor of Science at Harvard University.
For instance, solar panels “absorb light up to a certain wavelength and reflect the rest,” says Loeb. “This leads to a spectral edge in their reflected light, which is distinguishable from the ‘red spectral edge’ produced by vegetation...Such panels would be particularly useful for tidally locked planets that show the same side to the host star at all times.

No longer in the shadows, Pentagon's UFO unit will make some findings public - Baltimore Sun
Despite Pentagon statements that it disbanded a once-covert program to investigate unidentified flying objects, the effort remains underway — renamed and tucked inside the Office of Naval Intelligence, where officials continue to study mystifying encounters between military pilots and unidentified aerial vehicles.
Pentagon officials will not discuss the program, which is not classified but deals with classified matters. Yet it appeared last month in a Senate committee report outlining spending on the nation's intelligence agencies for the coming year. The report said the program, the Unidentified Aerial Phenomenon Task Force, was "to standardize collection and reporting" on sightings of unexplained aerial vehicles, and was to report at least some of its findings to the public every six months.
Immune System of Humans, Other Mammals Could Struggle to Fight Extraterrestrial Microorganisms |
In a new study published in the journal Microorganisms , a team of researchers from the UK, the Netherlands and Germany tested how mammalian immune cells responded to peptides containing two amino acids that are commonly found in carbonaceous meteorites. The immune response to these alien peptides was less efficient than the reaction to those common on Earth.

'We're all trying to make contact': the story of a moving new Netflix film | Documentary films |
In John Was Trying to Contact Aliens, a tender, grounded short film premiering on Netflix this month, Shepherd reflects on his decades-long infatuation with the potential of outer space – a search for meaning fulfilled, at least partially, in his small corner of Earth. The 16-minute film, which won the short film jury award at Sundance in January, finds Shepherd at home, still in northern Michigan, surrounded by machines that seem more at home now in a spoof of a 1960s sci-fi movie.
Shepherd was, it appears in the film, somewhat of a local media star in the era of sci-fi movies and space capers, having endeavored to contact (the operative word in the title is "trying") extraterrestrial beings. Adopted and raised by his grandparents, Shepherd was interested at an early age by what could be out there – an interest that, when articulated, resembles the yearnings of many others closer to Earth.
Many things are taking place:

Could 2020 feel any more cataclysmic? There's a deadly pandemic and a global economic crisis. New clashes over race have erupted in the United States. In the first six months of this year—this very year!—there were wildfires in Australia, deadly plane crashes in Pakistan and Iran, and impeachment trials in America. Not to mention Brexit. Remember Brexit?
