Exciting to see Earth from vantage point of ISS: Shubhanshu Shukla

Astronaut Shubhanshu Shukla on Friday said he and fellow astronauts on the International Space Station relished 'aam ras', 'gajar ka halwa', 'moong dal halwa' and delicacies from other countries as he completed a week on board the orbital lab. Shukla, who docked at the ISS on June 26 as part of the Axiom-4 mission, completed a week on the ISS and got a day off, which he spent connecting with family and friends back on Earth. The Axiom-4 (Ax-4) crew, which includes Shukla and three other astronauts, completed 113 orbits around the Earth by the end of July 3, clocking over 4.66 million km, which is equivalent to nearly 12 times the distance between the Earth and the moon. "It was a good moment. We got food from different countries and got to share it with all the crew," Shukla, who has the call sign Shux', said in a brief interaction with scientists at the URSC, Bengaluru over HAM radio connection. On Thursday, Shukla also became the Indian astronaut with the longest stay in space, .

Earth sets another heat record in January, expectations of cooler 2025

The world warmed to yet another monthly heat record in January, despite an abnormally chilly United States, a cooling La Nina and predictions of a slightly less hot 2025, according to the European climate service Copernicus. The surprising January heat record coincides with a new study by a climate science heavyweight, former top NASA scientist James Hansen, and others arguing that global warming is accelerating. It's a claim that's dividing the research community. January 2025 globally was 0.09 degrees Celsius (0.16 degrees Fahrenheit) warmer than January 2024, the previous hottest January, and was 1.75 degrees Celsius (3.15 degrees Fahrenheit) warmer than it was before industrial times, Copernicus calculated. It was the 18th month of the last 19 that the world hit or passed the internationally agreed upon warming limit of 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial times. Scientists won't regard the limit as breached unless and until global temperatures stay
