MétéoMédia - Is an intact piece of protoplanet Theia locked away inside the Moon?

Is an intact piece of protoplanet Theia locked away inside the Moon?
Scott Sutherland
mercredi, 11 mars 2020 à 11:30 - New research may solve a persistent mystery about how Earth s Moon formed.
New clues to the origin of the Moon surfaced this week, which reveal that the Earth and Moon are not as similar as previously thought, and part of the protoplanet that helped create the Moon may still be preserved deep under the lunar surface.
The current theory of how Earth and Moon came to be, as we know them today, is called the Giant-Impact Hypothesis. Essentially, billions of years ago, proto-Earth was all alone as it circled the Sun, until a fateful collision with a Mars-sized protoplanet scientists named Theia. The cataclysmic impact blasted both planets apart, and while much of Theia mixed together with proto-Earth, a cloud of debris that was blasted out into space eventually coalesced and cooled to form the Moon. ....

Scientists at Amrita Vishwa Vidyapeetham develop forest fire early detection system | India News

Representative image
NEW DELHI: Scientists at Amrita Vishwa Vidyapeetham in Kerala have developed a ‘forest fire early detection system’, using UAV and advanced computation technology to detect fires at an early stage and quickly alert officials.
The system, funded by Kerala government’s forest & wildlife department, is successfully tested in Chambra Peak in Wayanad. Unlike the satellite-based forest fire alerts system which is currently being used in the country, the system developed by Amrita Vishwa Vidyapeetham can detect fires at an early stage and provide live streaming of the location to forest officials to avoid a false alarm.
On the other hand, the existing detection system, using satellite imagery, takes landscape photos of the affected region and relays them to the forest officials after a gap of two days, making it difficult to stop the spread of the forest fires immediately. ....

MétéoMédia - Stunning but deadly, see the place on Earth where nothing survives

Stunning but deadly, see the place on Earth where nothing survives
Caroline Floyd
vendredi, 4 décembre 2020 à 11:30 - Scientists believe understanding the conditions on this part of Earth may help us understand habitats on other planets.
Life on Earth shows up in some surprising places. No matter how extreme the environment, some intrepid lifeform often a microorganism makes a home there. Species that live near hydrothermal vents in the ocean are an excellent example of these so-called extremophiles, who thrive in under the pressure of 2500 metres of water overhead, in temperatures up to 80ºC.
But even they don t care for the visually stunning but intensely hostile environment of Dallol. ....

Telesat is racing to launch a low-earth-orbit (LEO) satellite constellation to provide high-speed global broadband from space, pitting the satellite communications firm founded in 1969 against two trailblazing billionaires, Elon Musk and Jeff Bezos.
Musk, the Tesla Inc CEO who was only a year old when Telesat launched its first satellite, is putting the so-called Starlink LEO into orbit with his company SpaceX, and Amazon.com Inc, which Bezos founded, is planning a LEO called Project Kuiper. Bezos also owns Blue Origin, which builds rockets. ....
