    Closest Star System Found

    It's called WISE J104915.57-531906 - a pair of brown dwarfs located only 6.5 ly away (so close that Earth's television transmissions from 2006 are now arriving there). This system is the third-closest star system to the Sun!

    Here's the image:

    New star system found:

    [​IMG]

    A star HR 8799 with 4 planets (hot and toxic).

    That's really cool

    New Exoplanetary System Discovered

    Scientists have found the first multi-planet system that is tilted out of alignment with the host star.

    Another mystery ...

    Go figure dafuq happened there ..... All those invisible and unseen worlds ...

    Scientists find Earth-sized rocky exoplanet

    name: Kepler-78b
    radius: ~1.2 times that of Earth
    mass: ~1.7 times that of Earth
    location: ~400 ly from Earth in the constellation Cygnus

    Its density is the same as Earth’s, suggesting that it also made primarily of rock and iron.
    Kepler-78b orbits its star very closely every 8.5 hours, making it much too hot to support life.

    If you’ve ever wanted to know what 3538 exoplanets look like spinning around their stars, here you go!

    A team of European astronomers has discovered a second solar system, the closest parallel to our own solar system yet found.

    KOI-351
    is “the first system with a significant number of planets (seven) that shows a clear hierarchy like the solar system - with small, probably rocky, planets in the interior and gas giants in the exterior.

    As you can see this systems is extremely compact, 1AU!

    Currently, studying exoplanet atmospheres can be done when the planets are passing in front of their stars. Researchers can identify the gases in a planet’s atmosphere by determining which wavelengths of the star’s light are transmitted and which are partially absorbed.

    For the first time, astronomers have found faint but clear signatures of water in the atmospheres of five exoplanets. All five are so-called ‘hot Jupiters,’ massive worlds that orbit close to their host stars.

    Well then, it probably has amateur lifeforms. o_O



    Thanks for info. :D

    More new planets!!!!

    [​IMG]


    Three more exoplanets have been directly seen in astronomical images: FW Tau b, ROXs 42B b, ROXs 12 b.

    [​IMG]

    Now we have more than 1000 exoplanets that have been confirmed and cataloged!!!

    And here's nice video:

    My guess is that big boy is going to light up and become a binary partner.

    It's going to remain a brown dwarf - smoldering for eons but never fully light up. There are lots of those around, they're just really hard to spot.

    Here's a very good article:

    So we got a definitive answer now. If it's cold it won't be a star.

    A team of European astronomers confirmed the presence of Kepler-88 c, an unseen planet that was previously predicted thanks to the gravitational perturbation it caused on its transiting brother planet, Kepler-88 b.

    New planet, a hotter and puffier version of Earth! It's the first transiting Earth-mass planet ever found and is the lightest alien world to have both its mass and size measured.

    Another discovered exoplanets:

    And another one called Beta Pictoris b posted below. It's a very young planet - estimated to be <10 million years old (the star itself is ~ 12 million).

    Now they can image them directly. Truly amazing.

    New planet found:

    An international team of astronomers has discovered a new exoplanet, Kepler-410A b. The planet is about the size of Neptune and orbits the brightest star Kepler-410A in a double star system 425 ly from Earth.

    New exoplanet, named ULAS J222711-004547, with red skies

    Lol they discover new worlds everyday!

    Not exactly a planet, but not quite a star either. What I find amazing is this:

    So it has an atmosphere filled with clouds of Ruby dust?! What the hell..?

    ^ True, that's cool. It seems there's lot of aluminum oxide

    Kepler spacecraft found 715 planets orbiting 305 stars.




    715 new planets. Yup it's no joke.
