CARL SAGAN

These famous astronomers bettered our understanding of the universe.

These are the most scientifically accurate space movies we've seen - you won't find Armageddon anywhere near this list.

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.

In just a few short days, NASA's Perseverance rover is slated to land on Mars Thursday (Feb. 18), and it's bringing five "hidden gems" along with it. And that's just one of the many "hidden gems" on NASA's Perseverance rover.

Most of the alien civilizations that ever dotted our galaxy have probably killed themselves off already. It says where and when life is most likely to occur in the Milky Way, and identifies the most important factor affecting its prevalence: intelligent creatures' tendency toward self-annihilation. "Especially since the Hubble Space Telescope and Kepler Space Telescope, we have lots of knowledge about the densities [of gas and stars] in the Milky Way galaxy and star formation rates and exoplanet formation ... and the occurrence rate of supernova explosions. In other words, we're likely a frontier civilization in terms of galactic geography and relative latecomers to the self-aware Milky Way inhabitant scene. Even an extraordinarily low chance of a given civilization wiping itself out in any given century — say, via nuclear holocaust or runaway climate change — would mean that the overwhelming majority of peak Milky Way civilizations are already gone.

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.

Some of the promises made at the New York World's Fair remained unfulfilled, Tyson notes, while others have exceeded anything we might have thought possible. "Cosmos: Possible Worlds" imagines what the 2039 New York World's Fair could look like. A sweeping view of the 2039 New York World's Fair at night, with a monumental Tree of Life in the background. Against the backdrop of this possible future, Tyson asks us to think about how we can avoid repeating these mistakes.

The Carl Sagan Institute (formally known as the Carl Sagan Institute: The Pale Blue Dot & Beyond), an institute at Cornell University that is dedicated to furthering the search for, and the study of, habitable planets and moons, also joined in to celebrate the anniversary of the magnificent image.

In the video, a rotating cast of voices articulate one of Sagan's most famous quotes from his book "Pale Blue Dot." The Institute for Pale Blue Dots at Cornell University in Ithaca, New York,was renamed the Carl Sagan Institute: Pale Blue Dots and Beyond in a ceremony on May 9, 2015.

NASA released an updated version of the famous "Pale Blue Dot" image of Earth taken by Voyager to celebrate the photograph's 30th anniversary. Known as the " Pale Blue Dot " photo, the original image showed Earth as a tiny speck within a band of brightness caused by sunlight striking the spacecraft's instrument.

The original photo was a compilation of images taken using three different color filters.
