Smart material switches between heating and cooling in minutes
Monday, 01 November 2021 07:48
As anyone who has ever parked a car in the sun on a hot summer day knows, glass windows are great at letting sunlight in but terrible at allowing heat out. Now, engineers at Duke University have developed smart window-like technology that, with the flip of a switch, can alternate between harvesting heat from sunlight and allowing an object to cool. The approach could be a boon for HVAC savings, Astronomers discover massive galaxy 'shipyard' in the distant universe

Even galaxies don't like to be alone. While astronomers have known for a while that galaxies tend to congregate in groups and clusters, the process of going from formation to friend groups has remained an open question in cosmology.
In a paper published in the Astronomy and Astrophysics Journal, an international team of astronomers reports the discovery of a group of objects that appear to Chinese hypersonic test like a "Sputnik moment': top US general

The Pentagon's top general said Wednesday that China's recent test of an earth-circling hypersonic missile was akin to the Soviet Union's stunning launch of the world's first satellite, Sputnik, in 1957, which sparked the superpowers' space race.
Mark Milley, chairman of the Joint Chiefs of Staff, confirmed for the first time the Chinese test of a nuclear-capable missile that would be very d OpenET: A satellite-based water data resource
Monday, 01 November 2021 07:48
OpenET uses publicly available data to provide satellite-based information on evapotranspiration (the "ET" in OpenET). The primary satellite dataset for OpenET is from the Landsat program, a partnership between NASA and the U.S. Geological Survey (USGS). The most recent satellite in the program, Landsat 9, successfully launched on Sept. 27, 2021.

A yellow streak representing high concentrations of methane, a dangerous greenhouse gas, is visible over southern Iraq on a map produced by Kayrros, a French firm that uses satellites to track leaks from fossil fuel facilities.
The source of the immense leak discovered in 2019 was never officially confirmed - and it is only one of many.

Antarctic glacier named Glasgow to mark COP26
Sunday, 31 October 2021 12:30
Nine fast-flowing glaciers in West Antarctica have been named after locations of important climate treaties, conferences and reports. One of the glaciers is now called Glasgow Glacier to mark the city hosting the COP26 climate change conference. All the glaciers are in the Getz region, which, using data from satellites, was found recently to have lost more than 300 gigatonnes of ice over the last 25 years.
