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

    The European-Japanese planetary mission BepiColombo lifted off from the European spaceport in French Guiana at 03:45 Central European Summer time on 20 October 2018 (22:45 on 19 October local time), on board an Ariane 5 launch vehicle. "Not only is the mission designed to investigate the planet Mercury, it will also deliver new insights into the Solar System," explains Walther Pelzer, Executive Board Member for the Space Administration at the German Aerospace Center (Deutsches Zentrum für […]

  • 'Oumuamua one year later
    on October 22, 2018 at 10:09 am

    One year ago this week astronomers discovered an unusual object moving through space not too far from the Earth's orbit. In just a few days they realized it could not be a normal asteroid or comet – its path showed that it was not gravitationally bound to the solar system. It was, therefore, the first interstellar body ever discovered in our solar system that originated from outside it. It was given the Hawaiian name 'Oumuamua, "scout." […]

    To train future explorers to support NASA's mission to return to the Moon's surface, scientists use similar environments found on the Earth. Last week, a group of domestic and international students traveled to Barringer Meteorite Crater, Arizona (aka Meteor Crater) to learn necessary skills that could help NASA implement its plans for human and robotic missions to the lunar surface.

    New observations by two Arizona State University astronomers using the Hubble Space Telescope have caught a red dwarf star in a violent outburst, or superflare. The blast of radiation was more powerful than any such outburst ever detected from the Sun, and would likely affect the habiltability of any planets orbitiing it. […]
