NASA's Deep Space Optical Communications (DSOC) technology, demonstrated aboard the Psyche spacecraft, has achieved a groundbreaking milestone by successfully transmitting engineering data over 140 million miles using optical communication. Although Psyche primarily uses radio frequency for data transmission, this feat showcases the potential of optical communication for future missions, including sending humans to Mars.

A new model could explain the "cosmic glitch" at the edge of the expanding universe, where gravity weakens by about a per cent, according to new research. The widely accepted model of gravity comes from Einstein's theory of general relativity, which has been confirmed through multiple tests and experiments.

Astronomer Frederick Walter suggests gamma-ray bursts could have exterminated extraterrestrial civilizations, potentially explaining the lack of contact with alien life. Despite the threat, Earth's chances of being hit are low due to the rare, directed nature of GRBs.

A recent study has shed light on the origin of the near-Earth asteroid known as Kamo’oalewa, revealing that it likely originated from the Giordano Bruno crater on the moon's far side. This discovery marks the first time astronomers have traced a potentially hazardous asteroid back to a specific lunar crater, offering new perspectives on the dynamics between Earth and its celestial neighbor.

New research has presented compelling evidence for the existence of a hypothetical 'Planet Nine' in the outer regions of our solar system, challenging previous skepticism. This potential planet, initially proposed in 2016 by Caltech researchers Konstantin Batygin and Michael Brown, is believed to exert gravitational influence on the orbits of distant icy bodies that intersect Neptune's path.

According to a recent report by the Indian Space Research Organisation (ISRO), the Chandrayaan-3 moon mission of India encountered a four-second delay during launch. This delay was implemented as a precautionary measure to mitigate potential collisions with debris objects and satellites. The chairperson of Isro presented the Indian Space Situational Assessment Report (ISSAR) for 2023 on April 2.

Ahead of the monsoon season, the Union Health ministry announced on Monday its vigilant monitoring of seasonal influenza across different States/Union Territories. This surveillance is conducted in real-time through the Integrated Disease Surveillance Programme (IDSP) network. "As of now, there has been no abnormal, alarming rise in cases of seasonal flu in any part of the country," the Union Health Ministry said.

In a long-standing debate, experts discuss varied depression sub-types and genetic influences on stress reactions, challenging the reactive vs endogenous classification. Genetic risk impacts environment sensitivity, potentially affecting stress management strategies.
