Aditya-L1 is a solar observatory operated by the Indian Space Research Organisation (ISRO).

The solar observatory will monitor the sun with seven specially designed distinct scientific payloads, five of which have been developed by the ISRO. It will do so from its position at a gravitationally stable point in the Earth-sun system called Lagrange point 1 — around 1 million miles (1.5 million kilometers) from Earth — where a spacecraft can remain stable in relation to both bodies. ISRO describes the mission as a "satellite dedicated to the comprehensive study of the sun." The L1 suffix in the mission's name refers to this location, while "Aditya" means "the sun" in Sanskrit.

The Hubble Space Telescope has photographed a bright stellar nursery studded with dazzling infant stars.

Taken using Hubble's Wide Field Camera 3 instrument, the image captures a massive protostar called OH 339.88-1.26 lurking behind star-forming clouds of dust and gas. OH 339.88-1.26 lies an estimated 8,900 light-years from Earth in the constellation Ara.

During the protostellar phase, stars are still in the process of gathering mass from their parent molecular clouds. Despite its young age, OH 339.88-1.26 is estimated to be about 20 times the mass of the sun, according to a statement from the European Space Agency (ESA). (Hubble is a joint mission of NASA and ESA.)
