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 ..

LOFAR telescopes helped to discover 300000 new galaxies

An international team of more than 200 astronomers from 18 countries has published the first phase of a major new radio sky survey at unprecedented sensitivity using the Low Frequency Array (LOFAR) telescope in the journal Astronomy & Astrophysics. The survey discovered 3,00,000 hidden galaxies using radio astronomy in a tiny corner of the northern ..

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 ..

Square Kilometre Array Project

A verdict on where to site the Square Kilometre Array (SKA) radio telescope will be taken soon. The choices under considerations are: South Africa Australia and New Zealand The SKA will be built in the southern hemisphere, in South Africa or Australia and New Zealand, where the view of our own galaxy, the Milky Way, ..
