China’s rover finds signs of recent water on Mars, droughts likely ended the megacities of Indus Valley Civilisation

 A new study suggests water on Mars may be more widespread and recent than previously thought. Scientists reported the finding from China’s Mars rover in Science Advances on Friday, April 28, 2023. | Photo Credit: AP

From finding West Eurasian genetic imprint in ancient DNA from Kerala’s Pattanam to increasing heat stress burden in Global South due to humidity, a lot has happened this week in the field of science. Find the most recent discoveries and findings here.

Expanding upon the historic first images of black holes, scientists have unveiled the first picture showing the violent events unfolding around one of these ravenous cosmic behemoths, including the launching point of a colossal jet of high-energy particles shooting outward into space. The new image of Messier 87 shows the entire system with the base of the jet of hot plasma, a fuzzy ring of light from hot plasma falling into the black hole, and a central dark area - sort of a donut hole - created by the black hole’s presence.

The National Aeronautics and Space Administration (NASA) is training four people to live on planet Mars this summer. While the endeavor to send humans to the neighbouring planet on the part of the US space agency is not new, the four ‘Martians’ will be part of NASA's human exploration expedition on Mars. 

"During the simulation, crew members will carry out different types of mission activities, including simulated spacewalks, robotic operations, habitat maintenance, personal hygiene, exercise, and crop growth," Nasa said in a statement.

The crew will face environmental stressors such as resource limitations, isolation, and equipment failure in order to be as close to the situation on Mars when humans arrive. The team will be subjected to resource limitations, isolation, equipment failure, and significant workloads during their habitation."

NASA has also sent satellites, lander called InSight designed to give the Red Planet its first thorough checkup, and a rover mission that includes the rover Perseverance, the small robotic helicopter Ingenuity, and associated delivery systems.
