According to the measurement results of NASA sensors installed on the International Space Station, the heat-affected area near Seattle, Washington, USA can be seen in the image. The ECOsystem Space Thermal Radiometer Experiment (ECOSTRESS) on the space station measures the thermal energy emitted by the Earth’s surface in the infrared spectrum.
The data used to create this image captures what happened when the surface temperature in Seattle soared to 120 degrees Fahrenheit (49 degrees Celsius) around noon on Friday (June 25). The temperature of the earth’s surface does not reflect the temperature of the air. However, the current heat wave broke the temperature record for the entire Pacific Northwest.
According to a blog post by atmospheric scientist Cliff Mass, extreme heat waves are the result of high inland pressure and low pressure near the coast. This creates the right conditions for the strong east-west airflow and pushes fresh ocean air away from shore. coast.
The mysterious cloud captured by the senior telescope
moves between galaxies. The mysterious cloud of gas floating in the distant galaxy cluster captured by the European Space Agency’s XMM Newton telescope.
The ancient European X-ray telescope XMM Newton photographed an isolated cloud of gas in a distant cluster of galaxies, puzzling astronomers for four years. The gas cloud in the Abell 1367 star cluster, also known as the Leo star cluster, is larger than the Milky Way and was first discovered by the Subaru Telescope in Japan in 2017.
The electromagnetic spectrum observed in the Some of the visible light and X-rays from the cloud cluster appear to float between the cluster galaxies some 300 million light-years from Earth. The European Space Agency (ESA), which operates the 22-year-old XMM Newton, said in a statement that the cloud’s independent existence is surprising.
The image has been processed by a team of scientists from the University of Alabama in Huntsville, USA, as part of a study recently published in the Journal of the Royal Astronomical Society.
It shows the X-ray emission part of the cloud in blue and its hot gas in red. The white areas in the image show some visible galaxies in distant clusters.
Scientists do not know where this cloud came from, but believe that it somehow separated from a larger galaxy in the cluster. They expected it to be held together by a strong magnetic field to prevent it from being broken up by the gravitational pull of the surrounding matter. Tereza Pultarova
Crash Test Dummy Helps Improve Safety for Moon Explorers The
Crash Test Dummy is ready for safety testing on the Orion capsule.
A crash test dummy is preparing for a crash test on the Orion capsule at NASA’s Langley Research Center in Virginia. The space capsule will send humans to the moon in 2023 and will be placed in a hydro-impact basin during testing to help engineers assess potential damage to crew members from splashes after missions in deep space.
The manikin is equipped with sensors that can record the force exerted on the human body by this impact to help the team devise mitigation measures to protect the safety of the astronauts. During the mission to the moon, during the planned reentry profile, the crew is expected to experience 2.5 times the gravity and four times the gravity at two different points during the ascent.
