Astronomers reveal first image of black hole at the heart of Milky Way galaxy

Astronomers believe nearly all galaxies, including our own, have these giant black holes at their centre, where light and matter cannot escape, making it extremely hard to get images of them. Scientists from the Event Horizon Telescope(EHT) facility, a collaboration of over 300 researchers, revealed the first image of the black hole at the centre …

India’s ‘space economy’ valued at Rs. 36,794 crore

A collaboration between two leading research and educational institutes in Thiruvananthapuram has shed light on India’s “space economy,” the parameters of which have remained mostly ambiguous even as the country’s space programme has grown by leaps and bounds. Researchers from the Centre for Development Studies (CDS) and the Indian Institute of Space Science and Technology …

New observations help explain the universe’s most energetic objects

Observations of a doughnut-shaped cloud of cosmic dust and gas shrouding a massive black hole at the centre of a galaxy equal in size to our Milky Way have given scientists fresh insight into the universe’s most powerful objects. On Wednesday, scientists claimed their observations of the supermassive black hole at the centre of galaxy …

NASA launches first-ever laser communications system

NASA launched its new Laser Communications Relay Demonstration (LCRD)—the agency’s first-ever laser communications system—from Cape Canaveral Space Force Station in Florida on December 7 at 3.50 p.m. IST. The LCRD will assist the agency in conducting space-based optical communication tests. Currently, the majority of NASA spacecraft relay data using radio frequency communications. Optical communications will …

NCRA astronomers discover eight rare radio stars

A team of astronomers from the Pune-based National Centre for Radio Astrophysics (NCRA-TIFR) used the upgraded Giant Metrewave Radio Telescope (uGMRT) to discover eight stars belonging to a rare category known as “Main-sequence Radio Pulse” emitters, or MRPs, which will aid in the understanding of “exotic” radio stars and stellar magnetospheres. Because of the wide …

Giant black hole in galaxy M87 fires plasma jet at almost light speed

New computer models suggest that the first (and only) black hole ever seen from Earth sends out huge jets of plasma that move at almost the speed of light. The galaxy Messier 87, or M87, is 55 million light-years from Earth in the Virgo constellation, and it contains a black hole 6.5 billion times the …

Astronomers discover new way of studying the atmospheres of extra solar planets

Indian astronomers have discovered a new way to study the atmospheres of extra solar planets. They demonstrated that planets orbiting stars other than the Sun can be researched by researching polarisation fingerprints and detecting light polarisation. Existing technologies can detect these polarisation signals or fluctuations in light scattering strength, allowing for the research of planets …

Two astronomers discover Pulsating White Dwarf in TW Pictoris System using TESS

TW Pictoris is a cataclysmic variable system in the constellation Pictor that is roughly 1,400 light-years away. It’s made up of a white dwarf that gets its energy from an accretion ring around it, which is fueled by hydrogen and helium from its smaller partner star. The white dwarf becomes brighter as it grows. Using …
