![]() While this may sound like hogwash, readers gobbled up the idea of The Great Chennai Freeze, especially since the famed newspaper backed the outlandish claims with evidence of a volcanic eruption of Mount Tambora in distant Indonesia.Īccording to The Hindu, this Mount Tambora was the tallest peak in the archipelago, rising to 4,300 m. Today marks the 208th year anniversary of modern-day Chennai recording a temperature of -3☌ and witnessing snowfall - or so we’ve been led to believe.įor the unversed, in 2015, The Hindu published a report stating that 200 years ago, Madras recorded a morning temperature of 11☌ on April 24, and it subsequently plummeted to -3☌ by Friday, April 28! But there is a point to this hang in there. The findings of this study are detailed in the reputed journal Nature and can be accessed here.įor weather, science, space, and COVID-19 updates on the go, download The Weather Channel App (on Android and iOS store).If you’re reading this article sitting under the scorching sun somewhere in Chennai as sweat trickles down your forehead, the title will probably make you wistfully scoff at the ridiculousness of it all. "The coming years will be exciting, as we will be able to learn more about what happens near one of the most mysterious regions in the Universe," says Eduardo Ros from the Max Planck Institute for Radio Astronomy. The present image was obtained using 16 telescopes, including the Global Millimetre VLBI Array (GMVA), the Atacama Large Millimetre/submillimetre Array (ALMA), and the Greenland Telescope (GLT).įuture observations with this telescope network will aim to unravel the violent yet complicated processes around supermassive black holes, including how supermassive black holes can launch powerful jets. The black hole then bends and captures some of this light from hot plasma falling into it, creating a central dark area with a fuzzy accretion ring of light around it - looking quite similar to a ‘medu vada’ as seen from Earth. The capture also reveals for the first time how the base of a jet connects with the matter swirling around a supermassive black hole.Īs matter orbits the black hole, it heats up and emits light. It is also about 6.5 billion times more massive than our Sun. The black hole in question resides in the heart of the galaxy Messier 87 (M87), located about 55 million light-years away from us. Therefore, what we see is a system in its entirety - the black hole, its accretion ring (where matter falls into the black hole), the blazingly bright jet shooting out into space, and the region around this cosmic being. While previous photographs have captured a black hole and the region close to it separately, the new image has, for the first time ever, managed to provide a complete picture of this entity. But scientists are now a step closer to figuring it out using a first-of-its-kind picture of the 'shadow of a black hole'! Understanding how black holes launch such enormous jets has been a long-standing astronomical problem. When these supermassive beings aren't guzzling down bodies in their immediate vicinity, they spew out colossal jets of high-energy particles far into space - even beyond the galaxies they call their home! ![]() Black holes, with their ominous propensity to gobble up celestial neighbours and a gravitational pull so strong that even light fails to escape their clutches, are frequent occupants of galactic cores in the Universe.
