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

  • Touchdown: Japan probe Hayabusa2 lands on distant...
    on February 22, 2019 at 7:04 am

    A Japanese probe sent to collect samples from an asteroid 300 million kilometres away for clues about the origin of life and the solar system landed successfully on Friday, scientists said. […]

  • Research creates DNA-like molecule to aid search...
    on February 21, 2019 at 9:39 pm

    In a research breakthrough funded by NASA, scientists have synthesized a molecular system that, like DNA, can store and transmit information. This unprecedented feat suggests there could be an alternative to DNA-based life, as we know it on Earth – a genetic system for life that may be possible on other worlds. […]

  • Do volcanoes or an asteroid deserve blame for...
    on February 21, 2019 at 7:00 pm

    UC Berkeley scientists have obtained more precise dates for the Deccan Traps volcanic lava flows, linking peak activity more closely to the asteroid or comet impact 66 million years ago and the coincident mass extinction. But if greenhouse gases emitted before the impact created a hothouse climate that set life up for a fall when the impact cooled the planet, those gases did not coincide with the largest lava flows from the Deccan Traps. […]

    on February 21, 2019 at 2:30 pm

    By now, most of us have heard that the use of plastics is a big issue for the environment. Partly fuelled by the success of the BBC's Blue Planet II series, people are more aware than ever before about the dangers to wildlife caused by plastic pollution – as well as the impact it can have on human health – with industries promising money to tackle the issue. […]

    Researchers at CU Boulder are starting work on a new collaborative grant from NASA and the National Oceanic and Atmospheric Administration (NOAA) that will improve solar wind modeling. […]
