![]() ![]() ![]() But recent research suggests it may not be suitable for alien lifeforms. The outer planets are gas giants Jupiter and Saturn and ice giants Uranus and Neptune. JPL scientists tested new methods for detecting chemical signatures of life in the salty waters here, believing them to be analogs for water on Mars or ocean worlds like Europa. Venus has long been considered one of the most likely places to host extraterrestrial life within the solar system because of its similar size to Earth and location in the sun's habitable zone. NASAs newest rover Perseverance landed on Mars on Feb. Mono Lake, California, with salt pillars known as 'tufas' visible. If there are trace amounts of phosphine on Venus then they likely came from lightning strikes or volcanic activity, researchers said. But the new finding is one of the most definitive yet, thanks to the massive amounts of data collected by SOFIA, and puts a final nail in the coffin for the idea of extraterrestrial life on Venus. Several other studies have tried to repeat the results of the 2020 study, researchers said in the statement. As NASA explores the solar system, our understanding of life on Earth and the potential for life on other worlds has changed alongside the many discoveries. ![]() Moons of Jupiter and Saturn are known to harbor such oceans, some revealing through remote sensing at least a few of the characteristics we expect for habitable worlds. SSERVI advances lunar and planetary science through cross-disciplinary research and collaborations, providing technical analyses for NASA programs and missions. The new study is not the first to come up empty handed while looking for phosphine in Venus' atmosphere. Life on planets around other stars also might be hidden in a subsurface ocean encased in ice, invisible even to our most powerful space telescopes. It Could Find Hints Of Life On Far-Flung Planets. "The Sun is the last thing you want in the sky when you're doing these kinds of sensitive observations." "You don't want sunlight accidentally coming in and shining on your sensitive telescope instruments," study lead author Martin Cordiner, an astrochemist at NASA's Goddard Space Flight Center in Maryland, said in a statement. To see into Venus' atmosphere, SOFIA had to be activated within 30 minutes before sunset to avoid glare from the sun, and Venus had to be precisely oriented with Earth. are there life on any of these planets We're so excited specifically about the discovery. It took several months for researchers to get a good glimpse of Venus' atmosphere, because SOFIA only gave the team limited opportunities to focus on the planet. A ‘Soda Ocean’ on a Moon of Saturn Has All the Ingredients for Life. A large infrared telescope peers out of the side of the plane and into the cosmos. ![]()
