The Solar Orbiter of the European Space Agency (ESA) may have made progress in the eighty-year-old puzzle of why the Sun’s outer atmosphere is so heated. One long known solution discovered by scientists was nanoflares, which are tiny heating bursts. Several months into Solar Orbiter’s official mission, on March 3, 2022, the spacecraft’s Extreme Ultraviolet Imager (EUI) sent back data revealing for the first time that a magnetic process known as reconnection was occurring consistently on minuscule scales. The spaceship was approximately halfway between the Earth and the Sun at that moment. This made it possible to synchronize observations with…

A tremendous pulse of gamma-ray radiation that swept through our solar system on October 9, 2022, overwhelmed the gamma-ray detectors on multiple orbiting satellites and sent astronomers on the run to investigate the event using the most potent telescopes in the world. The newly discovered source, designated GRB 221009A in honor of the time it was found, ended up becoming the brightest gamma-ray burst (GRB) ever observed.The gamma-ray burst, which lasted for more than 300 seconds, is thought to be the first sign of the birth of a black hole, which is created when the center of a large, rapidly…

On January 20, the Indian Space Research Organisation (ISRO) successfully completed a qualification test of its High Thrust VIKAS Engine at the ISRO Propulsion Complex (IPRC) in Mahendragiri, Tamil Nadu. In order to get ready for the Gaganyaan mission, which will launch later this year, the engine was fired for 25 seconds. ISRO Successfully Tests Vikas Engine Beyond Nominal Operating Parameters According to ISRO, the engine performed as expected during the test, and its parameters nearly matched what the engineers had predicted. In their report, ISRO stated that the purpose of the test was to “check the robustness of the…

A recent meta-analysis from the Harvard T.H. Chan School of Public Health suggests that exposure to fine particle air pollution (PM2.5) may raise the risk of dementia. The study is the first systematic review and meta-analysis to make use of the brand-new Risk of Bias In Non-Randomized Studies of Exposure (ROBINS-E) tool, which goes into greater detail than prior assessment methods for bias in environmental studies. It is also the first to incorporate more recent studies that made use of the “active case ascertainment” technique, which entailed screening the complete study populations before evaluating those who were dementia-free at baseline…

Just before sunrise on the 738th Sol of the mission—a Martian day—Perseverance NASA’s Rover discovered floating clouds on Mars. The pictures were taken with the rover’s navigation camera. Perseverance and Curiosity, two NASA rovers that are now exploring the surface of the planet, have both previously observed clouds there. The US space agency earlier this month unveiled photographs of “God Rays,” or Sun rays caused by clouds blocking a low-lying Sun, which were taken for the first time on the planet. The Curiosity rover is the one that took the pictures. In particular, at an altitude of 50 and 80…

Two super pressure balloon (SPB) launches are slated by NASA’s Scientific Balloon Program from Wanaka, New Zealand, to further test and qualify the technology. NASA is also flying science payloads as missions of opportunity on each balloon, even though the two launches are primarily intended to test the SPB technology. During their projected up to 100-day flights, the balloons may also be visible from the ground. During the first voyage that is planned, a Super Pressure Balloon Imaging Telescope (SuperBIT) from Princeton University will take flight. A balloon platform is used by this telescope to observe huge galaxy clusters in…

Saturn’s upper atmosphere is being heated by its extensive ring system, says recent studies. Throughout the history of the solar system, the occurrence has never been observed. It’s an unusual interplay between the planet and its rings that may offer a method for foretelling if planets surrounding other stars also have magnificent ring systems similar to Saturn’s. The information was kept out of sight for forty years. The ability to put it all together within a year, however, required the experience of a seasoned astronomer who used observations of Saturn from the now-retired Cassini probe, the Voyager 1 and 2…

The Shenzhou-15 crew of Chinese astronauts has undertaken three spacewalks since their four-month space flight (CMSA) reports the China Manned Space Agency . The third was completed on Thursday, 30, March 2024. Along with astronaut Deng Qingming, who was on board the space station, astronauts Fei Junlong and Zhang Lu completed the third spacewalk. The two successfully completed all of their assigned tasks before returning to the lab module Wentian. Since the Shenzhou-12 human mission in 2021, four crews have completed 10 spacewalks, mastering several important technologies. CMSA announced Extravehicular follow-up operations will proceed regularly as scheduled. On October…

A region on distant exoplanets known as the “terminator zone” is a ring on planets that constantly have one side facing its star and one side that is always dark. According to a recent study, astronomers from the University of California, Irvine explain how the possibility of extraterrestrial life exists on distant exoplanets within this region. The line separating the day and night sides of a planet is known as the terminator. Terminator zones may exist in the right temperature range between too hot and too cold. The constant darkness of terminator planets would result in freezing temperatures that could…

The first onsite IBM-managed health care quantum computer deployment in the private sector in the US was formally presented today by Cleveland Clinic and IBM. The IBM Quantum System One installed at Cleveland Clinic will be the first quantum computer in the world to be entirely devoted to healthcare research, with the aim of supporting Cleveland Clinic in speeding scientific discoveries. About Cleveland Clinic : Cleveland Clinic is a nonprofit academic medical center with many different specializations that integrates clinical and hospital treatment with training and research. It was established in Cleveland, Ohio, in 1921 by four eminent doctors with…
