United Kingdom Research and Innovation (UKRI) has embarked on a collaboration with India's Department of Atomic Energy to explore opportunities to set up super computing facilities to process data from the observations made by the Square Kilometre Array radio telescope. The Science and Technology Facilities Council of the UKRI also announced initiatives to harness technologies such as artificial intelligence, machine learning, bio-imaging and accelerator development to augment scientific research and have a tangible impact in areas such as cancer treatment. "The challenge with Square Kilometre Array (SKA) is that it produces vast amounts of data and you have to apply super computing techniques to turn that data very rapidly into things that astronomers can use. That is an area where we intend to collaborate," Mark Thomson, Executive Chairman of Science and Technology Facilities Council (STFC), told PTI at an event here to mark 15 years of the UKRI-India partnership.

International Astronomy Day is observed two times every year. This Day falls on or close to the first quarter moon. One is celebrated in Spring and the other one in Autumn

After the launch of Chandrayaan-3 Moon lander and Aditya-L1 ventures, ISRO has readied a mission aimed at enhancing cutting edge scientific understanding in Astronomy. XPoSat (X-ray Polarimeter Satellite) is India's first dedicated polarimetry mission to study various dynamics of bright astronomical X-ray sources in extreme conditions. The spacecraft will carry two scientific payloads in a low earth orbit. The primary payload POLIX (Polarimeter Instrument in X-rays) will measure the polarimetry parameters (degree and angle of polarization) in medium X-ray energy range of 8-30 keV photons of astronomical origin. The XSPECT (X-ray Spectroscopy and Timing) payload will give spectroscopic information in the energy range of 0.8-15 keV, according to ISRO. "XPoSat is ready for launch," an official of the national space agency headquartered here said on Saturday. According to ISRO, the emission mechanism from various astronomical sources such as blackholes, neutron stars, active galactic

Four eclipse events including a total solar eclipse would occur in 2023 and two of them would be visible in India, an astronomy expert said here on Wednesday. There would be two solar eclipses and two lunar eclipses, said Dr Rajendra Prakash Gupt, Superintendent of Ujjain's Government Jiwaji Observatory. The celestial events will start with a total solar eclipse on April 20. "But it will not be visible from India," Dr Gupt said. It will be followed by a 'penumbral' lunar eclipse on the intervening night of May 5-6 which will be visible in India, he said. A penumbral lunar eclipse occurs when the Moon passes through penumbra or lighter part of Earth's shadow, and sunlight falling on the Moon appears to be partially cut off. The Moon remains visible, but with less-than-usual brightness. The only 'annular solar eclipse' will take place on the intervening night of October 14 and 15, but it would not be visible in the country as it would happen at night. A partial lunar eclipse wou

Astronomers have discovered the closest known black hole to Earth, just 1,600 light-years away. Scientists reported Friday that this black hole is 10 times more massive than our sun. And it's three times closer than the previous record-holder. It was identified by observing the motion of its companion star, which orbits the black hole at about the same distance as Earth orbits the sun. The black hole was initially identified using the European Space Agency's Gaia spacecraft, said Kareem El-Badry of the Harvard-Smithsonian Centre for Astrophysics. El-Badry and his team followed up with the International Gemini Observatory in Hawaii to confirm their findings, which were published in Monthly Notices of the Royal Astronomical Society. The researchers are uncertain how the system formed in the Milky Way. Named Gaia BH1, it's located in the constellation Ophiuchus, the serpent-bearer.

Astronomers have discovered the heaviest element ever found in an exoplanet atmosphere barium. They were surprised to discover barium at high altitudes in the atmospheres of the ultra-hot gas giants WASP-76 b and WASP-121 b two exoplanets, planets which orbit stars outside our Solar System. This unexpected discovery raises questions about what these exotic atmospheres may be like."The puzzling and counterintuitive part is: why is there such a heavy element in the upper layers of the atmosphere of these planets?" says Tomas Azevedo Silva, a PhD student at the University of Porto and the Instituto de Astrofisica e Ciencias do Espaco (IA) in Portugal who led the study published today in Astronomy & Astrophysics.WASP-76 b and WASP-121 b are no ordinary exoplanets. Both are known as ultra-hot Jupiters as they are comparable in size to Jupiter whilst having extremely high surface temperatures soaring above 1000°C. This is due to their close proximity to their host stars, which also ...

The deal signed by NASA and Space Exploration Technologies Corp. called for collaborating on a feasibility study of such a mission, though NASA has yet to commit to such a flight.

Astronomers have assembled the largest-ever compilation of high-precision galaxy distances, called Cosmicflows-4.Galaxies, such as the Milky Way, are the building blocks of the universe, each comprised of up to several hundred billion stars. Galaxies beyond our immediate neighborhood are rushing away, faster if they are more distant, which is a consequence of the expansion of the universe that began at the moment of the Big Bang. Measurements of the distances of galaxies, coupled with information about their velocities away from us, determine the scale of the universe and the time that has elapsed since its birth."Since galaxies were identified as separate from the Milky Way a hundred years ago, astronomers have been trying to measure their distances," said Tully. "Now by combining our more accurate and abundant tools, we are able to measure distances of galaxies, and the related expansion rate of the universe and the time since the universe was born with a precision of a few per ...
