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

Best of both worlds: Asteroids and massive mergers
on August 16, 2019 at 1:51 pm
The race is on. Since the construction of technology able to detect the ripples in space and time triggered by collisions from massive objects in the universe, astronomers around the world have been searching for the bursts of light that could accompany such collisions, which are thought to be the sources of rare heavy elements.

NASA has selected two proposals to demonstrate small satellite technologies to improve science observations in deep space, which could help NASA develop better models to predict space weather events that can affect astronauts and spacecraft.

How astronomers chase new worlds in TESS data
on August 15, 2019 at 3:00 pm
As pink liquid oozed around her shoes, astronomer Johanna Teske started to feel sick. She had been looking for new planets with the Planet Finder Spectrograph, an astronomical instrument resembling an industrial-sized refrigerator mounted to the Magellan II telescope. One night in October 2018, a hose leading to the instrument burst, causing pink coolant to spill onto sensitive parts of the instrument and the surrounding platform. Would Teske's search be ruined?

Many dream of what they would do had they a time machine. Some would travel 100 million years back in time, when dinosaurs roamed the Earth. Not many, though, would think of taking a telescope with them, and if, having done so, observe Saturn and its rings.

Shift to renewable electricity a win-win at...
on August 15, 2019 at 12:17 pm
Amid rollbacks of the Clean Power Plan and other environmental regulations at the federal level, several U.S. states, cities, and towns have resolved to take matters into their own hands and implement policies to promote renewable energy and reduce greenhouse gas emissions. One popular approach, now in effect in 29 states and the District of Columbia, is to set renewable portfolio standards (RPS), which require electricity suppliers to source a designated percentage of electricity from […]
