    The Kepler space telescope was invaluable at identifying thousands of candidate stars who are likely to have planetary systems. Now the nest step is to image such systems directly to discover more about them. The Gemini Planet Imager is the first step in that quest and is already giving good results.

    On topic; I have played with Eyes on Exoplanets a bit. It's fun and I tend to stay more interested with these graphical interfaces.

    Gah some people are so ignorant. Many media articles about distant objects such as planets, black holes, etc include an artists impression of how the object might look. The number of people who take these to be actual photos is staggering.

    Oh wow!

    http://www.abc.net.au/news/2017-02-...anets-orbiting-nearby-star-discovered/8293172

    What the article there doesn't say is that the planets are so close together that they would appear larger than our moon. You would be able to see continents and weather (if they exists ofcause).

    The star will be burning for trillions of years to come. A galactic safe heaven only 40ly aways.

    Edit: on the gravitational stability of the system (which is a thought, since the planets are so close together)...

    I think I heard this morning that all of the planets are tidally locked too, so that would be an issue. Before we even get to solar activity and whether any of the planets have a strong enough magnetosphere. There are already a bunch of media outlets giving the impression that a manned colonisation mission is next on the cards, (can't begrudge them their click bait I guess), but it's a very interesting system nonetheless.

    Thats a 'probable' because of the hypothesis that they spiraled inwards some time in the past. It hasn't been confirmed via observation as yet.

    A major find today;

    https://www.eso.org/public/news/eso1821/

    We can now observe a solar system being created :wired: :thumbup:

    Earth-sized, habitable-zone exoplanet found hiding in Kepler data

    https://bgr.com/2020/04/17/astronomers-just-found-an-exoplanet-shockingly-similar-to-earth/

    As far as i am aware a lot of planets found to date in habitable zones were crazy sizes, this is pretty neat!

    There is quite probably a lot of moons (earth sized ones) and what not also in the habitable zones.

    We were finding a lot of super earths or bigger in habitual zones, because our techniques were biased and only found large planets. Wouldn't be suprised if we find that "Earths" are fairly common. We just aren't able to detect them yet.
