Clouds of Venus Could Host Extraterrestrial Life Forms

  Clouds of Venus Could Host Extraterrestrial Life Forms <p>In the quest to answer whether we’re alone, scientists have found that the clouds of venus may help solve the mystery of whether life outside of Earth exists.</p>Published March 30 in the journal Astrobiology, a new paper says the clouds of Venus may host extraterrestrial microbial life. As the authors state in the paper, whether Venus’ clouds could support life has been discussed for decades, spurred by research indicating that its chemical and physical properties, moderate temperatures and pressure could make it possible for life to exist.

On April 16 NASA is launching a new planet - hunting telescope , the Transiting Exoplanet Survey Satellite (TESS) on a SpaceX Falcon 9 rocket, to take over the reigns. But it’ll be a sad day when Kepler finally comes to an end. Its legacy, though, will live long into the future.

NASA ’s next planet hunter , the Transiting Exoplanet Survey Satellite (TESS), is scheduled to launch as early as April 16, 2018. Powerful telescopes like NASA ’s upcoming James Webb Space Telescope can then further study these exoplanets to search for important characteristics, like their

NASA is planning to launch its next telescope into space on Monday during a window that opens at 6:32 p.m. Eastern time. The instrument, called the Transiting Exoplanet Survey Satellite and nicknamed TESS, is designed to identify thousands of exoplanets. Scientists are excited about the prospect the mission holds for new discoveries, but if you're just learning about the mission now, here's what you need to know.

TESS is the successor to Kepler, which revolutionized exoplanet science and is responsible for spotting almost three quarters of the planets astronomers have identified to date. But Kepler will run out of fuel sometime in the next few months, so scientists have been working for years to make sure something would be ready to replace it.

The new mission was inspired by Kepler's approach to spotting exoplanets, although planning for TESS began before Kepler even launched. Both telescopes are designed to spot the tiny dips in a star's brightness as a planet passes between the telescope and the star.

Kepler's main mission did that for a specific patch of stars, staring at the same section of the sky constantly. Instead, TESS is designed to cover the whole sky in 26 different segments. "One of the things that had never really been done in space was a comprehensive search for transits," TESS scientific leader George Ricker, an astronomer at MIT, told Newsweek.

But TESS is still targeting a specific subset of stars: It is focused on small bright stars that are fairly close to Earth. "This will really be the first time that many of these really bright stars, that have names, that we know and love, will be surveyed for variations," Ricker said.

There's also a practical reason for prioritizing planets located around these bright stars. They will be easiest for astronomers to study again with the even higher-powered telescopes they'll need to start understanding what the planets look like—and, for example, whether they might be attractive to life.

Those planets will be quite close to their star, since TESS will need to spot them orbit multiple times in a given 27-day-long survey of a specific sky segment. According to the predictions mission scientists have made for the telescope, it should be able to find about 20,000 exoplanets, of which dozens should be about the size of Earth. "It's a huge crop of planets," Ricker said.

TESS will hitch a ride on a Falcon 9 rocket and should begin observations about two months after its arrival in space. The survey is scheduled to last two years, although the telescope will be able to stay in its orbit for decades so NASA could easily extend its mission.

SpaceX blasts off NASA's new planet-hunter, TESS .
NASA on Wednesday blasted off its newest planet-hunting spacecraft, TESS, a $337 million satellite that aims to scan 85 percent of the skies for cosmic bodies where life may exist. "Three, two, one and liftoff!" said a NASA commentator as the Transiting Exoplanet Survey Satellite (TESS) soared into the blue sky atop a SpaceX Falcon 9 rocket from Cape Canaveral, Florida at 6:51 pm (2251 GMT).The washing machine-sized spacecraft is built to search outside the solar system, scanning the nearest, brightest stars for signs of periodic dimming. These so-called "transits" may mean that planets are in orbit around them.
