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

New Mars rover is ready for space lasers
on September 28, 2020 at 8:37 pm
When the Apollo astronauts landed on the Moon, they brought devices with them called retroreflectors, which are essentially small arrays of mirrors. The plan was for scientists on Earth to aim lasers at them and calculate the time it took for the beams to return. This provided exceptionally precise measurements of the Moon's orbit and shape, including how it changed slightly based on Earth's gravitational pull.

A new study authored by Southwest Research Institute scientists Rodrigo Leiva and Marc Buie reveals the binary nature of a trans-Neptunian object (TNO). Leiva and Buie utilized data obtained by the Research and Education Collaborative Occultation Network (RECON), a citizen science research net-work dedicated to observing the outer solar system. The study was published this month in The Astrophysical Journal.

CHEOPS keeps its promise: Observations with the space telescope have revealed details of the exoplanet WASP-189b—one of the most extreme planets known. CHEOPS is a joint mission by the European Space Agency (ESA) and Switzerland, under the aegis of the University of Bern in collaboration with the University of Geneva.
