A new study says there are lots of stars and planets in our galactic neighborhood that can get a good glimpse of Earth and its civilization.

Here’s a collection curated by The Associated Press’ entertainment journalists of what’s arriving on TV, streaming services and music platforms this week. MOVIES— “Enola Holmes”: It’s somewhat fitting that “Stranger Things” breakout Millie Bobby Brown gets her first starring role in a Netflix film, “Enola Holmes,” coming to the streamer Wednesday. — The Bonnaroo Music and Arts Festival was supposed to take place in June in Tennessee but was canceled because of the coronavirus pandemic. This week, though, the festival is launching Virtual ROO-ALITY, a three-night live broadcast featuring new performances as well as content from the Bonnaroo archive. The two-hour film will be available at 7 p.m. EDT Tuesday at pbs.org/frontline and on YouTube at 9 p.m. EDT.

Astronomers have found a potential sign of life high in the atmosphere of neighboring Venus: hints there may be bizarre microbes living in the sulfuric acid-laden clouds of the hothouse planet. They said it doesn't satisfy the “extraordinary claims require extraordinary evidence" standard established by the late Carl Sagan, who speculated about the possibility of life in the clouds of Venus in 1967. “It’s not a smoking gun," said study co-author David Clements, an Imperial College of London astrophysicist. After three astronomers met in a bar in Hawaii, they decided to look that way at the closest planet to Earth: Venus. ... Not a single process we looked at could produce phosphine in high enough quantities to explain our team’s findings.”That leaves life.

A new study published in the journal Nature Astronomy proposes that the material silica aerogel could be used to mimic the greenhouse effect in our own atmosphere to make parts of Mars habitable for humans. In a 1971 paper, astronomer Carl Sagan suggested a way of terraforming Mars, or making it more habitable for humans. Researchers tested this proposal and found that the total yield would fall short of making the planet habitable. A new study published Monday in the journal Nature Astronomy proposes that the material silica aerogel could be used to mimic the greenhouse effect in our own atmosphere to make parts of Mars habitable for humans. "Unlike the previous ideas to make Mars habitable, this is something that can be developed and tested systematically with materials and technology we already have."
