This 360° panorama depicts the surface of a newly detected planet, TRAPPIST-1d, part of a seven planet system some 40 light years away. You can explore this artist’s rendering of an alien world by moving the view using your mouse or your mobile device. The depiction is based on the latest scientific data about this planetary system, and this world’s sister planets can be seen as bright points of light in a dark sky. Each world is roughly in Earth’s size range, in terms of both mass and diameter. Further observations will be needed to determine whether any or all of these worlds might be habitable. — YouTube 360 Video Information, NASA Jet Propulsion Laboratory

Planetary system is a set of gravitationally bound non-stellar objects in or out of orbit around a star or star system. Generally speaking, systems with one or more planets constitute a planetary system, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets, planetesimals and circumstellar disks. The Sun together with its planetary system, which includes Earth, is known as the Solar System. The term exoplanetary system is sometimes used in reference to other planetary systems.

As of 1 August 2018, there are 3,815 confirmed planets in 2,853 systems, with 633 systems having more than one planet. Debris disks are also known to be common, though other objects are more difficult to observe.

Of particular interest to astrobiology is the habitable zone of planetary systems where planets could have surface liquid water, and thus the capacity to harbor Earth-like life. — Wikipedia

  • How Earth sheds heat into space
    on September 24, 2018 at 7:00 pm

    Just as an oven gives off more heat to the surrounding kitchen as its internal temperature rises, the Earth sheds more heat into space as its surface warms up. Since the 1950s, scientists have observed a surprisingly straightforward, linear relationship between the Earth's surface temperature and its outgoing heat. […]

    on September 24, 2018 at 1:07 pm

    A catalogue that provides an overview of over 2,200 planetary maps produced worldwide between 1600 and 2018 has been presented today at the European Planetary Science Congress (EPSC) 2018 in Berlin. The catalogue has been produced by Henrik Hargitai, from Eötvös Loránd University in Budapest (Hungary), and Mateusz Pitura, from the University of Wroclaw (Poland). […]

    on September 21, 2018 at 6:00 pm

    Origami and high-performance textiles are transforming architecture plans for smart human habitats and research stations on the Moon and Mars. Initial field tests of the MoonMars project's origami prototype will be presented at the European Planetary Science Congress (EPSC) 2018 in Berlin by Dr. Anna Sitnikova. […]

  • NASA balloon mission captures electric blue clouds
    on September 20, 2018 at 6:44 pm

    On the cusp of our atmosphere live a thin group of seasonal electric blue clouds. Forming 50 miles above the poles in summer, these clouds are known as noctilucent clouds or polar mesospheric clouds—PMCs. A recent NASA long-duration balloon mission observed these clouds over the course of five days at their home in the mesosphere. The resulting photos, which scientists have just begun to analyze, will help us better understand turbulence in the atmosphere, as well as in oceans, lakes and […]
