Jupiter-Size Alien World Is Biggest 'Tatooine' Planet with 2 Suns Ever Found

  Jupiter-Size Alien World Is Biggest 'Tatooine' Planet with 2 Suns Ever Found A newfound alien world is the biggest ever discovered that has two suns in its sky, like Luke Skywalker's home planet of of Tatooine in the "Star Wars" universe.Whereas the fictional Tatooine is a small and rocky world, however, the real-life Kepler-1647b is a gas giant about the size and mass of Jupiter. In addition to being the biggest known two-star planet, Kepler-1647b also has the widest orbit, circling its host stars in 1,107 Earth days, astronomers said.

Astronomers are narrowing the field in their search for a "second Earth."

An international team of researchers has identified the 20 most Earth-like worlds among the more than 4,000 exoplanet candidates that NASA's Kepler space telescope has detected to date, scientists report in a new study.

All 20 potential "second Earths" lie within the habitable zones of their sun-like stars — meaning they should be able to harbor liquid water on their surfaces — and are likely rocky, the researchers said. [The Search for Another Earth (Video)]

Amazing Photo Shows Likely Alien Planet 1,200 Light-Years Away

  Amazing Photo Shows Likely Alien Planet 1,200 Light-Years Away A jaw-dropping new photo shows a probable alien planet orbiting a star that lies 1,200 light-years from Earth. The potential planet appears as a brownish dot to the left of the bright bluish-white star CVSO 30 in the newly released image, which was captured by the European Southern Observatory's (ESO) Very Large Telescope in Chile.To appreciate just how fantastic it is to have a direct image of this candidate world, consider that CVSO 30 is about 280 times farther away from Earth than is Alpha Centauri, the star system nearest to our own. And remember also that 1 light-year is about 5.9 trillion miles (9.

Identifying these Earth-like planets is important in the hunt for alien life, said study lead author Stephen Kane, an associate professor of physics and astronomy at San Francisco State University (SFSU).

"[It] means we can focus in on the planets in this paper and perform follow-up studies to learn more about them, including if they are indeed habitable," Kane said in a statement.

Kane and his team sorted through the 216 habitable-zone Kepler planets and candidates found so far. (A "candidate" is a world that has yet to be confirmed by follow-up observations or analysis. Kepler has found about 4,700 candidates to date, more than 2,300 of which have been confirmed; about 90 percent of all candidates should eventually turn out to be the real deal, mission team members have said.)

Second-Earth candidates had to be safely within the habitable zone. If a planet is too close to the inner edge, it could experience a runaway greenhouse effect like the one that occurred on Venus. And if it's too close to the outer edge, the planet could end up being a frigid world like Mars, the researchers said.

In addition to categorizing the planets by their place in the habitable zone, Kane and his team also sorted them by size, ruling out worlds that were big enough to be gaseous.

There are five confirmed planets in the top 20: Kepler-186f, Kepler-62f, Kepler-283c, Kepler-296f and Kepler-442b. The other 15 are unconfirmed candidates.

Categorizations like this suggest that the universe is teeming with planets that could possibly harbor life, study team members said.

"It's exciting to see the sheer amount of planets that are out there," study co-author Michelle Hill, an Australian undergraduate studying abroad at SFSU, said in the same statement. "[It] makes you think that there is zero chance of there not being another place where life could be found."

Alien: Covenant wraps filming as Twitter account shares image of Katherine Waterston on set

  Alien: Covenant wraps filming as Twitter account shares image of Katherine Waterston on set Ridley Scott's eagerly-anticipated Prometheus sequel-turned Alien prequel, Alien: Covenant, has officially finished filming. Twitter account Alien Anthology shared the news on the social media platform, alongside a black-and-white photograph of the Oscar-nominated film-maker and lead actress Katherine Waterston on set. Earlier this week, second movie in the original series, Aliens, celebrated its 30th birthday (having been released in the US on 18 July 1986) while 5 July saw the anniversary of Scott beginning production on the film that started it all, Alien, way back in 1978. So it makes sense that Alien: Covenant mark its own special day by wrapping in the same month, too. While it's far from being confirmed, the new image can't help but fuel speculation that Waterston's character Daniels will be linked to Sigourney Weaver's Ellen Ripley in some way. Back in June, The Playlist reported that the former would be portraying Ripley's mother in the upcoming sequel, which wouldn't be too far-fetched given the pair's similarities in hairstyle and clothing here. But then again, that could just be the "astronaut" look that Scott likes to present. Filming has wrapped. The next phase begins. #AlienCovenantpic.twitter.

The new study has been accepted for publication in The Astrophysical Journal. You can read it for free on the online preprint site ArXiv.org here: http://arxiv.org/pdf/1608.00620v1.pdf
