NCRA astronomers discover “Main-sequence Radio Pulse’ emitters”

Astronomers from Pune-based National centre for Radio Astrophysics (NCRA) have discovered eight stars which belong to a rare class called Main-sequence Radio Pulse emitters or MRPs. Key Points MRPs were discovered using ‘Giant Metre-wave Radio Telescope (GMRT)’ located in Pune. Group of scientists discovered the rare class of radio stars which are hotter than the ..

Astronomers from Japan, Taiwan, and Princeton University discover 83 quasars powered by supermassive black holes in distant universe

Astronomers from Japan, Taiwan, and Princeton University have discovered 83 quasars powered by supermassive black holes in the distant universe, which were formed when the universe was only 5% of its current age. These quasars are lying 13 billion light-years away from the Earth. The team used data taken with ‘Hyper Suprime-Cam’ (HSC) instrument, mounted ..

Station Explorer for X-ray Timing and Navigation Technology (SEXTANT)

NASA has invented a new type of autonomous space navigation that could see human-made spacecraft heading into the far reaches of the Solar System, and even farther – by using pulsars as guide stars. It’s called Station Explorer for X-ray Timing and Navigation Technology, or SEXTANT (named after an 18th century nautical navigation instrument), and it ..

Gravitational Waves

Gravitational Waves were for the first time discovered in February, 2016, 100 years after they were hypothesized by Albert Einstein in 1916. These waves were detected by the scientists working at two LIGO (Laser Interferometer Gravitational-wave Observatory) facilities in United States. LIGO scientists detected these gravitational waves produced by collision of two black holes located ..
