54 The selloff picked pace after the World Health Organization (WHO), late Wednesday night, termed the the new coronavirus outbreak as a pandemic, and expressed deep concern over the "alarming levels of inaction".Besides selloff in global equities, massive plunge in international oil prices and depreciating rupee added to investor concerns, they added.The new coronavirus that first originated in the Chinese city of Wuhan in December last year has claimed over 4,200 lives and infected more than 117,330 people across 107 countries and territories.75 points, or 4.In the previous session, the 30-share BSE barometer settled 62.On a net basis, foreign institutional investors sold equities worth Rs 3,515.All Sen*** components were trading in the red.86 in morning session.38 crore, while domestic institutional investors bought shares worth Rs 2,835.29 per cent and Tokyo cracked up to 5.50 against US dollar in morning session.The rupee too plunged 82 paise to 74..Incessant foreign fund outflow also spooked market participants, traders said.63 per cent, lower at 34,044.95 points or 0.Similarly, the NSE Nifty cracked 486.46 crore on Wednesday, data available with stock exchanges showed.

The 30-share index was trading 1,652.Brent crude oil futures plunged over 5 per cent to USD 34 per barrel, after the travel ban. Tata Steel was the top loser, tanking up to 9 per cent, followed by ONGC, SBI, Titan, Axis Bank, M&M, UltraTech Cement, L&T and Reliance Industries.Elsewhere in Asia, bourses in Shanghai dropped over 1.66 per cent, Seoul 4.40.65 per cent, to 9,971.45 points or 0.18 per cent higher at 35,697.65.Continuing its downward spiral, domestic BSE Sen*** sank 1,821.32 per cent.Mumbai: Equity benchmark Sen*** plummeted over 1,800 points and the broader Nifty gave up the 10,000 level in opening session loose-leaf notebook for sale on Thursday as worsening rout in world markets, after WHO declared coronavirus a pandemic, flared up fears of a global economic recession.07 per cent up at 10,458.34 per cent, Hong Kong 3.Following the announcement, US President Donald Trump suspended all travel from Europe, excluding the UK, to the US for the next 30 days to stop the spread of the virus.27 points at open.40, and the Nifty closed 6.In overnight trade, US equity benckmarks also plunged nearly 5 per cent, intensifying the global rout. China remains the hardest-hit with over 80,000 infections and 3,000 deaths.According to traders, volatility peaked in global markets after WHO's announcement describing the coronavirus outbreak as a pandemic.

Now, we can literally see the Milky Way with new eyes," she added.". The Sun lies only 500 light-years from the Wave at its closest point."Studying stellar births is complicated by imperfect data.The wave consists of stellar nurseries that have been previously thought to form a part of the &China sticker notepad suppliers39;Gould's Belt', which is a band of star-forming regions and is believed to have an orientation around the Sun in a circular or ring-like fashion. But determining how much mass the clouds have, how large they are -- has been difficult, because these properties depend on how far away the cloud is.Using the new data researchers recently augmented these techniques, which dramatically improves the ability of astronomers for measuring the distances to star-forming regions.The study was enabled through a relatively new analysis of data from the European Space Agency's Gaia spacecraft which was launched in 2013 along with the mission of precisely measuring the distance, position, and motion of the stars."Gould and Herschel both observed bright stars forming in an arc projected on the sky, so for a long time, people have been trying to figure out if these molecular clouds actually form a ring in 3D," said another researcher, Joao Alves. The work which was led by the researcher Zucker has been published in the Astrophysical Journal."We don't know what causes this shape but it could be like a ripple in a pond as if something extraordinarily massive landed in our galaxy," said Alves. So, to create an accurate map of our solar neighborhood, we combined observations from space telescopes like Gaia with astrostatistics, data visualization, and numerical simulations," said Zucker.

Agreeing to the claims by Zucker and Finkbeiner, Goodman said, "All of the stars in the universe, including our Sun, are formed in dynamic, collapsing, clouds of gas and dust."No astronomer expected that we live next to a giant, wave-like collection of gas -- or that it forms the Local Arm of the Milky Way," said the researcher, Alyssa Goodman. It passed by a festival of supernovae as it crossed Orion 13 million years ago, and in another 13 million years it will cross the structure again, sort of like we are 'surfing the wave," Alves added.The researchers combined the data from Gaia which was super-accurate, with other measurements for constructing a detailed, 3D map of interstellar matter in the Milky Way, and noticed an unexpected pattern in the # spiral arm which is closest to the Earth.According to the research which has been published in the journal - Nature - the wave structure is the largest ever seen in the galaxy and is made up of interconnected stellar nurseries.This discovery by the university transforms the 150-year-old vision of the nearby stellar nurseries as an expanding ring in one featuring a star-forming filament that reached trillions of miles below and above the galactic disk. The Wave's very existence is forcing us to rethink our understanding of the Milky Way's 3D structure," Goodman added.The researchers further discovered a thin, long structure, about 9,000 light-years long and 400 light-years wide, having a shape that of a wave, cresting 500 light-years above and below the mid-plane of our galaxy's disk.A long-standing challenge for astronomy and astronomers is disentangling structures that are present in the 'dusty' galactic neighbourhood."We suspected there might be larger structures that we just couldn't put in context."What we do know is that our Sun interacts with this structure."We pulled this team together so we could go beyond processing and tabulating the data to actively visualizing it -- not just for ourselves but for everyone.Astronomers from Harvard University have found the presence of a wave-shaped gaseous structure named 'Radcliffe Wave' in the Milky Way Galaxy."We were completely shocked when we first realized how long and straight the Radcliffe Wave is, looking down on it from above in 3D -- but how sinusoidal it is when viewed from Earth."Instead, what we've observed is the largest coherent gas structure we know of in the galaxy, organized not in a ring but in a massive, undulating filament.

The newly developed three-dimensional map shows Earth's galactic neighborhood in a new light, which gives researchers a revised view of the Milky Way and is also opening the door to some of the major discoveries. It's been right in front of our eyes all the time, but we couldn't see it until now," Alves added. We risk getting the details wrong because if you're confused about distance, you're confused about size," another researcher Finkbeiner said. In previous studies, a group of researchers mapped the three-dimensional distribution of dust using a vast survey of stars.
