Astronomers have detected the oldest (and the most distant) black hole from the early universe which dates from 400 million years after the big bang. Surprisingly, this is about a few million times the mass of Sun. Under the...
Solar wind, the stream of electrically charged particles emanating from the outer atmospheric layer corona of Sun, poses threat to life form and electrical technology based modern human society. Earth’s magnetic field provide protection against the incoming solar wind...
The Laser Interferometer Space Antenna (LISA) mission has received the go ahead of European Space Agency (ESA). This paves the way for developing the instruments and spacecrafts commencing January 2025. The mission is led by ESA and is a...
The findings of the BioRock experiment indicate that bacterial supported mining can be carried out in the space. Following the success of BioRock study, the  BioAsteroid experiment is currently underway now. In this study, bacteria and fungi are being grown on asteroidal material in an incubator under...
Scientists have successfully taken first ever picture of the shadow of a black hole providing direct observation of its immediate environment Image taken from "EHTC, Akiyama K et al 2019, 'First M87 Event Horizon Telescope Results. I. The Shadow of...
The researchers have studied the turbulence in Sun’s corona using radio signals sent to Earth by the ultra-low-cost Mars orbiter when the Earth and Mars were in conjunction on the opposite sides of the Sun (the conjunction usually happens...
UAE’s MBR Space Centre has collaborated with NASA to provide an airlock for the first lunar space station Gateway that will orbit the Moon to support long-term exploration of the Moon under NASA’s Artemis Interplanetary Mission. An Air lock is an...
NASA’s mission update on 05th August 2023 said Voyager 2 communications has paused. Communications should resume once the spacecraft’s antenna is realigned with Earth in mid-October 2023.   On 4th August 2023, NASA had reestablished full communications with Voyager 2...
The solar observatory spacecraft, Aditya-L1 was successfully inserted in Halo-Orbit about 1.5 million km away from earth on 6th January 2024. It was launched on 2nd September 2023 by ISRO.   The Halo orbit is a periodic, three-dimensional orbit at Lagrangian point L1 involving Sun, Earth...
In recently published papers, researchers have estimated the rate of supernova core collapse in the Milky Way to be 1.63 ± 0.46 events per century. Therefore, given the last supernova event, SN 1987A was observed 35 years ago in...
Astronomers have recently reported detection of such a compact object of about 2.35 solar masses in the globular cluster NGC 1851 in our home galaxy Milkyway. Because this is at the lower end of “black hole mass-gap", this compact object...
Astrobiology suggest that life is abundant in the universe and the primitive microbial life forms (beyond earth) could be found earlier than intelligent forms. The search for the extra-terrestrial life involves looking for biological signatures in the vicinity of...
A nebula is a star-forming, massive region of interstellar cloud of dust in the galaxy. Looking like a monster, this is image of a massive nebula in our home galaxy Milky Way.   The image was captured by NASA’s Spitzer Space Telescope.  These types of regions cannot...
Of the several comets discovered in 2021, the comet C/2021 A1, called Comet Leonard after it’s discoverer Gregory Leonard, may become visible to the naked eye on 12 December 2021 when it comes closest to the Earth (at the distance of...
Voyager 1, the most distant man-made object in history, has resumed sending signal to the Earth after a gap of five months. On 14 November 2023, It had stopped sending readable science and engineering data to Earth following a...
Discovery of the first exoplanet candidate in X-ray binary M51-ULS-1 in the spiral galaxy Messier 51 (M51), also called the Whirlpool Galaxy using transit technique by observing dips in brightness at X-ray wavelengths (instead of optical wavelengths) is pathbreaking and a game changer because it...
Fast Radio Burst FRB 20220610A, the most powerful radio burst ever observed was detected on 10 June 2022. It had originated from a source that existed 8.5 billion years ago when the universe was just 5 billion years old...
Stars have a life cycle spanning a few million to trillions of years. They are born, undergo changes with the passage of time and finally meet their end when fuel runs out to become a very dense remanent body....
James Webb Space Telescope (JWST), the space observatory designed to conduct infrared astronomy and launched successfully on 25 December 2021 will enable two research teams to study earliest galaxies in the universe. The research teams will use JWST’s powerful...
The first detection of carbon dioxide in the atmosphere of a planet outside the solar system, the first image of an exoplanet by JWST, the first image of an exoplanet ever taken at deep infrared wavelength, the first detection of...
''....astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one...
James Webb Space Telescope (JWST) will specialise exclusively in infrared astronomy to study early universe. It will search for optical/infrared signals from the early stars and galaxies formed in the Universe soon after the Big Bang for a better...
In order to explore the dark energy, the Dark Energy Spectroscopic Instrument (DESI) at Berkeley Lab has created largest and most detailed ever 3D map of the Universe by obtaining optical spectra from millions of galaxies and quasars. The...
Two decades ago, two Mars rovers Spirit and Opportunity landed on Mars on 3rd and 24th January 2004, respectively to look for evidence that water once flowed on the surface of the Red Planet. Designed to last just 3...
ISRO has successfully launched the satellite XPoSat which is world’s second ‘X-ray Polarimetry Space Observatory’. This will carry out research in space-based polarisation measurements of X-ray emission from various cosmic sources. Earlier, NASA had sent ‘Imaging X-ray Polarimetry Explorer...
