LAMOST reveals new footprints of the Gaia-Sausage-Enceladus merger event
Tuesday, 16 March 2021 06:01
Looking up at the starry sky, the deep Universe appears quiet and mysterious. It is hard to imagine that the ancient dwarf galaxy Enceladus violently collided and was torn apart by our own Milky Way Galaxy, leaving behind the cries of a whole new generation of children from the hundred-handed giant.

Today Roboze, a manufacturer of industrial 3D printing technology for extreme end-use applications, announced it has been selected by the University of Colorado Boulder to optimize the design and 3D printed components for a CubeSat project within the college's department of Aerospace Engineering Sciences. The CubeSat will spend at least six months in orbit measuring electromagnetic waves emitted Cosmic lens reveals faint radio galaxy

Radio telescopes are the world's most sensitive radio receivers, capable of finding extremely faint wisps of radio emission coming from objects at the farthest reaches of the universe. Recently, a team of astronomers used the National Science Foundation's Karl G. Jansky Very Large Array (VLA) to take advantage of a helping hand from nature to detect a distant galaxy that likely is the faintest r Lightning strikes played a vital role in life's origins on Earth
Tuesday, 16 March 2021 06:01
Lightning strikes were just as important as meteorites in creating the perfect conditions for life to emerge on Earth, geologists say.
Minerals delivered to Earth in meteorites more than 4 billion years ago have long been advocated as key ingredients for the development of life on our planet.
Scientists believed minimal amounts of these minerals were also brought to early Earth throu Congressional Democrats urge Biden to cut defense spending

ESA astronaut Thomas Pesquet will serve as commander of the International Space Station towards the end of his second mission, called Alpha, currently slated to begin on 22 April this year. The announcement was made during today’s press briefing.
Thomas will be the fourth European to hold the post of commander, after ESA astronauts Frank De Winne, Alexander Gerst and Luca Parmitano. During the briefing, Thomas remarked how three back-to-back European commanders underscores the growing role of Europe in space exploration and is a testament to the hard work of ESA colleagues.
‘I am unbelievably humbled and honoured’, said Thomas.

Scientists unearth meteorite from the birth of the solar system
Monday, 15 March 2021 14:12
Scientists believe they have identified a meteorite formed in the first million years of our solar system, making it the oldest known meteor of volcanic origin.
The space rock, which began its journey some 4.5 billion years ago, has already proved an "exceptional" witness to the building blocks of the planets.
Known as Erg Chech 002, the meteorite was discovered in May 2020 by meteor hunters in the Algerian Sahara desert. It had rested undisturbed for "at least 100 years", according to Jean-Alix Barrat, a geochemist at France's Brest University.
In a recent study published in the Proceedings of the National Academy of Sciences journal, Barrat and his colleagues describe its discovery and several rare features.
There are 43 officially documented fragments, but "probably about a hundred" either still in the ground or unaccounted for, said the study.

Israel unveils laser-guided 'precision' mortar system
Monday, 15 March 2021 12:17
Israel unveiled Sunday a laser-guided mortar system that it said could reduce civilian collateral damage, as the Jewish state faces an International Criminal Court investigation into possible war crimes.
The "Iron Sting" system, developed by the Israeli military with local firm Elbit Systems, will use laser and GPS technology to provide maximal accuracy to 120mm mortar rounds, the defence mi AFRL collaborates with Purdue University on autonomy challenge project
