Scientists have discovered ancient asteroid ice fossils that could reveal what our solar system was like billions of years ago.
In a new study, the scientists analyzed a 4.6-billion-year-old primitive meteorite , called Acfer 094, that crash-landed in the Sahara desert in Algeria in 1990. (A primitive meteorite is a rocky remnant of the solar nebula, or the gaseous cloud that some say condensed into the objects in the solar system , that has fallen to Earth).
This may worth something:
Deadly 50,000C 'Wall of Fire' surrounding our Solar System discovered by Nasa probe
The giant wall of fire is made up of material ejected by our Sun and reaches temperatures of nearly 50,000C (90,000F).
Little is known about the scorching region at the edge of the Solar System, but Nasa is shedding light on it thanks to one of its deep space probes.
Voyager 2 crossed into interstellar space – the stuff between the stars in the Milky Way galaxy – late last year.
Our Solar System Is Blanketed in a Giant Wall of Fire
At the outermost edges of our solar system lies a barrier of super-hot plasma — a giant wall of fire from the Sun that defines the edge of interstellar space.
As Voyager 2 began its journey into interstellar space in late 2018, it recorded temperatures as high as 49,427 degrees Celsius (89,000 degrees Fahrenheit), according to Nerdist . And while the space probe seems to be fine, the plasma shield could pose a problem to NASA as it moves towards its planned interstellar mission .
NASA Space Robot Tested in Antarctica
The robot, designed for a future Europa mission, is a buoyant rover with two independent wheels to maneuver along the under-side of the ice. Engineer from the NASA Jet Propulsion Laboratory, Dr Andy Klesh, said the meter-long rover will be able to roam around taking samples and pictures.

“The rover is unique in that it uses buoyancy to stick to the underside of the ice and move upside-down using wheels, so it can get up close to the ice-water interface for sensitive measurements,” he said. “The robot can also stay in the one spot for long periods without having to expend energy like a submarine does.”

Pakistan gas field powered by 10 MW off-grid solar system – pv magazine International
Italian oil and gas company Eni has completed a solar park at its Bhit Gas Field. The plant, which took six months to build, is integrated into the field's generation system.

Italian oil and gas company Eni has completed the 10 MW solar project at its Pakistan gas field which was announced in March .
The off-grid project was built near the Bhit Gas Field which is 180km north of Karachi in the Kirthar region, and in which Eni New Energy Pakistan holds a 40% stake. The solar plant is integrated with the gas field's power generation systems and is expected to generate around 20 GWh per year.
Sunworks developing 653-kW solar system for California dairy farm
Sunworks , a provider of high-performance solar power solutions for agriculture, commercial, industrial, public works and residential markets, has been awarded an engineering, procurement and construction contract to develop a 653-kW ground mount solar system for a privately-held dairy farm in California’s Central Valley.
“This project expands our agricultural, commercial and industrial pipeline, and reinforces our presence in the California market,” said Chuck Cargile, CEO of Sunworks. “The system will reduce operating costs for Lima Ranch Dairy and enable them to better control the costs and access to electricity. We expect to recognize revenue related to this project in the second and third quarters of 2020.
Ball State planetarium's student staff helps Muncie community learn about solar system | Ball
Editor's Note: A previous version of this article misspelled Daniel Brossard's name. It has since been updated and corrected.
Under the 52-foot dome in the Charles W. Brown Planetarium, more than 20,000 visitors a year learn about what exists beyond the Earth's atmosphere in space. But before visitors sit back and look up at the simulated sky, they are first greeted by Ball State students who work behind the scenes.
Meet three individuals from the planetarium's student staff who have said their love for astronomy and physics is everlasting.
Interstellar Bodies Originating From Beyond Our Solar System - SpaceRef
Astonishingly, not one but two interstellar asteroids have been detected entering our solar system since 2017.
The first was given the Hawaiian name 'Oumuamua, meaning 'messenger from afar,' after its discovery by Canadian astronomer Robert Weryk. The second, 2I/Borisov, was named for its discoverer Gennadiy Borisov.
Paul Wiegert from Western University's Institute for Earth & Space Exploration is now tracing the origins of these far-travelling bodies with his former undergraduate student Tim Hallatt, the lead author on the paper, now a graduate student at McGill University.
