Alien life might thrive on the moons of these 121 giant planets

  Alien life might thrive on the moons of these 121 giant planets Moons orbiting huge exoplanets may be even better places to live than Earth, scientists say. But there's a catch.An international team of scientists has identified 121 gas giant planets, each at least three times more massive than Earth, that orbit in the habitable zones of their stars and are each expected to play host to several large moons.

When NASA finally sends its mega-powerful James Webb Space Telescope it will be the end of a long and troubled road, but it will also be the beginning of an extremely exciting time for astronomers. The telescope’s primary duty will be to sniff out exoplanets and learn more about them, potentially even detecting planets that would be suitable for human settlement after Earth.

But as NASA explains in a new blog post, learning how to properly harness the telescope’s power won’t be an overnight affair, and it’s going to need a bit of training before it can really flex its muscles. To help scientists get a handle on how the powerful instrument works they’re going to point it at larger targets first, like massive gas giant exoplanets.

NASA’s next flagship space telescope is delayed again

  NASA’s next flagship space telescope is delayed again NASA has again delayed the launch of its next-generation space observatory, known as the James Webb Space Telescope (JWST), the space agency announced today. The telescope now has a new launch date of March 30th, 2021. It’s the second delay to the project’s timeline this year, and the third in the last nine months.“We’re all disappointed that the culmination of Webb and its launch is taking longer than expected, but we’re creating something new here.

The James Webb Space Telescope ( JWST ) has a giant sunshield that divides the craft in two: one side facing the sun, which will power the device, and another to The telescope will now be subjected to two years of tests before its planned launch in 2018. James Webb space telescope . Nasa .

Compared with what we can do today, here's a look at six things a giant space telescope like this This figure shows the real stars in the sky for which a planet in the habitable zone can be observed. While James Webb will be NASA 's flagship astrophysics mission of the 2010s and WFIRST will fly in

“We have two main goals,” Jacob Bean, a co-principal investigator studying exoplanets, explains.” The first is to get transiting exoplanet datasets from Webb to the astronomical community as soon as possible. The second is to do some great science so that astronomers and the public can see how powerful this observatory is.”

That all sounds lovely, but first NASA has to actually get the thing into space. For a project that is eating up cash like crazy, that’s actually a lot harder than it might sound. The James Webb Space Telescope is a long, long time coming. You may have recently read about how NASA was forced to push back the launch of the telescope to 2021, but that’s really just the tip of a very large iceberg.

When the work first began on the telescope back in 1997 (!), the original launch was slated for 2007. Since then, the telescope has seen no fewer than 14 significant delays, and a cost increase from an initial budget of $500 million to nearly $10 billion. Much of this falls on Northrop Grumman, the contractor that was hired to build the telescope, and an independent review has found that countless stupid human errors like lost fasteners and incorrect cleaning agents have cost hundreds of millions of dollars to correct.

The telescope will eventually be finished (we hope) and once it is, there’s no telling what new things it might teach us about space and nearby planets. NASA promises that it will be worth the wait, and those are big words when it comes to a nearly $10 billion dollar project that is well over a decade late already. We’ll just have to wait and see.

Exoplanets Bigger Than Earth Could Be Rich In Water .
Scientists used data from Kepler Space Telescope and Gaia satellite to determine which exoplanets could have water.Despite identifying thousands of exoplanets, the search for life beyond Earth still continues. Several scientists across the globe are scouring the cosmos to pinpoint biosignatures — indicators of life — or the conditions required to support life on any of the known worlds.
