Astronomers observe stellar winds from aging stars in unprecedented detail

Science
Sept. 17 (UPI) -- Astronomers have captured high resolution images of stellar winds emanating from a diversity of aging stars. The observations, detailed Thursday in the journal Science, suggest the dramatic shapes of planetary nebulae are formed by interactions between stellar winds and nearby planets and stars. Advertisement As dying stars swell and cool, they expel particles and shed mass, producing stellar winds. As the red giants continue to age and evolve, they heat up again, casting off layers of ejected stellar material. Stellar radiation causes these sloughed layers to glow, creating what astronomers call planetary nebulae. Scientists have long struggled to explain the wide variety of shapes and colors that characterize planetary nebulae. "The sun, which will ultimately become a...
Climate change: ‘Unprecedented’ ice loss as Greenland breaks record

Climate change: ‘Unprecedented’ ice loss as Greenland breaks record

Science
Scientists say the loss of ice in Greenland lurched forward again last year, breaking the previous record by 15%.A new analysis says that the scale of the melt was "unprecedented" in records dating back to 1948.High pressure systems that became blocked over Greenland last Summer were the immediate cause of the huge losses.But the authors say ongoing emissions of carbon are pushing Greenland into an era of more extreme melting.Over the past 30 years, Greenland's contribution to global sea levels has grown significantly as ice losses have increased. A major international report on Greenland released last December concluded that it was losing ice seven times faster than it was during the 1990s. Today's new study shows that trend is continuing. Using data fro...

NEW DELHI: Former RBI governor Raghuram Rajan on Tuesday said non-performing assets of the banking sector are likely to witness unprecedented increase in the next six months and the sooner the problem is recognised the better it would be.

"The level of the NPAs is going to be unprecedented in six months from now if we really recognise the true level of NPAs...We are in trouble and sooner we recognise it, better it is because we really need to deal with the problem,” Rajan said during a session at the India Policy Forum 2020 organised by NCAER.

miodrag ignjatovicThe economic crisis caused by the coronavirus outbreak is  anything the world has ever experienced.Unlike the recession in the 1980s, the bond collapse of 1994, the Asian currency crisis or the 2008 subprime mortgage disaster, this is not a financial crisis. It is an economic crisis. And, although financial crises occur with some regularity, most have more localized impact zones.In this case, almost every major economy in the world has been negatively impacted by some form of societal lockdown. The fact that it came amidst a strong and growing global economy made it nothing short of a seismic systemic shock.This unprecedented crisis demands that finance professionals recognize the leadership role we need to play in guiding investors through ongoing volatility to calm...
