    Lightning strike so bright it lit up the solar panels. Or maybe it's an emission in Chernobyl

    So much vapor looked like it would be a cool launch, then aborted at T-13 seconds.

    Looks like SpaceX has managed to make rocket landings boring.

    If they had a decent PR team they know to make every 3rd booster explode to keep people interested in watching

    Sadly NASA always does these click bait press conference titles. In the end it turns out to be nothing

    It's beyond our solar system, so it's not that. Rumor has it that they've discovered something interesting about three, Earth-sized planets around Trappist-1, a red dwarf 40 light years from Earth.

    Spitzer observation request

    The recently detected TRAPPIST-1 planetary system represents a unique opportunity to extend the nascent field of comparative exoplanetology into the realm of temperate terrestrial worlds. It is composed of at least three Earth-sized planets similar in sizes and irradiations to Earth and Venus transiting an ultra-cool dwarf star only 39 light-years away. Thanks to the Jupiter-size and infrared brightness of their host star, the planets are amenable for detailed atmospheric characterization with JWST, including for biosignatures detection. Our Spitzer Exploration Science Program aims to prepare and optimize the detailed study of this fascinating planetary system through the two following complementary sub-programs: (1) a 480 hrs continuous monitoring of the star to explore its full inner system up to its ice line in a search for any other transiting object(s) (planet, moon, Trojan) with a sensitivity high enough to detect any body as small as Ganymede, and (2) the observation of ~130 transits of the planets (520 hrs). This second part has two goals. First, to measure precisely the planets' masses and eccentricities through the Transit Timing Variations method, to constrain strongly their compositions and energy budgets. Secondly, to measure with an extremely high precision the planets' effective radii at 4.5 microns to assess, when combined with future HST/WFC3 observations, the presence of an atmosphere around them. The two complementary parts of this program will make it a long-lasting legacy of Spitzer to the fields of comparative exoplanetology and astrobiology, by providing the necessary measurements on the inner system of TRAPPIST-1 (complete census, masses, eccentricities, first insights on atmospheres) required to initiate and optimize the detailed atmospheric characterization of its different components with JWST and other future facilities.
    Abstract for a Hubble Observation Time Request, as a followup to the Spitzer observation

    ABSTRACT
    Owing to over 1500 hours of monitoring including a recent 20-d long follow-up with the Spitzer Space Telescope, we have now constrained the architecture of TRAPPIST-1's system up to its ice line. There is no doubt left regarding the system uniqueness for Earth-sized comparative planetology and for the search for extrasolar habitats.
    The present request for DDT will fulfill the urgent need to inform the community about TRAPPIST-1 planets in order to guide their follow-up, notably in the context of the upcoming JWST Cycle 1 proposal. We request 23 HST/WFC3 orbits to assess the presence of extended atmospheres.

    Mate if you thought the whole "liquid water on Mars" discovery was "nothing"...then I really don't know what to say.

    Business Insider jumped the gun a bit and took the article down, but they had posted the discovery of seven planets around TRAPPIST-1, six of which are in or near the habitable zone.

    I'm beginning to think that red dwarves might be better places to look for earth size planets in the habitable zone than larger stars. The planets will almost always be tidally locked to the sun and the red dwarves are very often flare stars, but there are an enormous amount of red dwarves and therefore a good chance that some of them are viable for life.
