Isro launched ESA's Proba-3 mission on December 5th, after a delay due to a propulsion system anomaly. The two satellites will study the Sun's corona by flying in precise formation, a key demonstration for future missions. This marks ESA's return to launching with Isro after 23 years and follows Isro's recent Aditya-L1 solar mission.
"Younger women generally have a higher risk of recurrence than older postmenopausal women, but most studies on anti-hormonal therapy have mainly included postmenopausal women. We therefore wanted to compare the long-term benefit from the treatment in both groups," says Linda Lindstrom, associate professor and research group leader at the Department of Oncology-Pathology, Karolinska Institutet, who led the study.
A 70 cm asteroid is expected to enter Earth's atmosphere over northern Siberia tonight around 9:45 pm IST. Experts predict it will burn up, creating a stunning fireball, posing no danger to Earth. This event highlights the advancements in asteroid tracking technology by NASA and ESA and the importance of monitoring near-Earth objects for planetary defense.
India and European space agencies collaborate on Proba-3, the first precision formation flying mission to study the Sun's corona. The mission involves two small satellites creating an artificial eclipse to enable extensive solar research. Scheduled for launch on December 4, it will provide a significant boost in study time for solar observations.
Researchers discovered that chloride-rich depressions in Mars' Terra Sirenum region likely harbored water, creating potential conditions favorable for ancient microbial life. Sedimentary studies suggest the area experienced wetting and drying cycles, essential for life. This finding underscores the importance of these regions for future Mars missions aiming to explore past life signs and Mars' wet history.
Astronomers have pinpointed the source of slow, repeating radio bursts from space to a red dwarf star likely orbiting a white dwarf. These unusual signals, discovered in 2022, challenge existing theories about how pulsars emit radio waves and stem from interactions between the red dwarf's stellar wind and the white dwarf's magnetic field.
The mounting congestion in low Earth orbit from thousands of satellites and millions of debris pieces creates significant collision risks, threatening global communication and navigation systems. The UN panel urges the creation of a centralized shared database to track orbital objects and highlights the need for international cooperation and robust regulations to ensure space safety and sustainability.
