Six hot rocky exoplanets could shed light on the geology of planets in our solar system | Daily
Six 'very hot' rocky exoplanets orbiting stars in the local region of the Milky Way hold the key to understanding more about how the Earth was formed, astronomers claim.
Researchers from the Open University have been studying planets discovered by the European Space Observatory's planet-hunting telescope in Chile.
They are orbiting stars between 160 and 440 light years from Earth and all have hot surfaces with temperatures of around 2,012F to 3,272F.
Kärcher cleans up on energy efficiency with solar array - Power Engineering International
South Korea solar company Q Cells has supplied a 299.77 kWp commercial and industrial solar PV array at the UK headquarters of German cleaning equipment manufacturer Kärcher.
The solar system comprises 967 modules and was installed in seven days. Due to a lack of suitable storage space onsite, Q Cells supplied the solar modules to developer Solar Perfect in a split delivery.
Kärcher will utilise all the energy delivered by the system and Solar Perfect estimates that the array will mitigate the effects of 3.19 tonnes of CO 2 annually.

As more communities across Western New York continue to sign on to Gov. Andrew Cuomo’s green energy campaign of energy alternatives – namely commercial utility solar installations – many are also contending with unfavorable reactions from residents and questions on capacity. Some are also now reconsidering their options.

Have researchers solved Newton's three-body problem? | MNN - Mother Nature Network
If you thought that Issac Newton made physics simple, think again. The laws of motion might themselves be simple equations, but the actual motions of objects according to these laws can get complicated fast.
For instance, imagine a universe with just two objects in it: say, two stars. Newton's laws are reasonably sufficient for helping us to understand how these gravitationally bound objects will interact with each other. But add a third object — a third star, perhaps — and our calculations become dicey.

Nasa releases never-before-seen image of mysterious object that arrived from another solar system
The image shows the comet in front of a distant spiral galaxy, which can be made out to the side. But the focus of the imags is the bright blue centre of the image, which was taken by the Hubble Space Telescope as it tracked the comet through space.

Since then, scientists have been taking images of the comet as it moves nearer to the Earth and can be seen in better detail. The first observations from Hubble came in October, and the new images come from November and December, offering a better look at the size and other details of the visitor.
Enphase Energy Deploys One-Millionth Microinverter-Based Solar System
FREMONT, Calif., Dec. 17, 2019 (GLOBE NEWSWIRE) -- Enphase Energy, Inc. ( ENPH ), a global energy technology company and the world's leading supplier of solar microinverters, today announced the installation of the Company's one-millionth Enphase microinverter-based solar system. With over 23 million microinverters shipped, there are now more than 6.5 gigawatts DC of Enphase-based systems deployed in 130 countries.
"The partnership with Enphase has helped us make clean energy and savings accessible to well over 5,300 working families since 2012, and we are delighted to have the one-millionth Enphase system deployed in one of our projects," said Erica Mackie, co-founder and CEO at GRID Alternatives.
