The MoU signed between the two organisations will pave the way for future collaborations between ISRO and CUHP in establishing the observational facilities, specifically ground based optical sensors for space object tracking, deep space exploration, R&D related to astrophysics and Near Earth Objects (NEO).

Scientists map living corals before and after marine heat wave
Scientists map living corals before and after marine heat wave

With these data, the researchers identified more than 10 potential coral refugia - habitats that may offer a safe haven for corals facing climate change. Among the potential refugia, there was up to 40 per cent less coral mortality than on neighbouring reefs, despite similar heat stress.

NASA scientists crack 60-yr-old mystery of explosions on Sun

An explosive process called magnetic reconnection triggers solar flares, which can, in just minutes, release enough energy to power the whole world for 20,000 years. Scientists have spent the last half-century trying to understand how this process happens.
