Tidal disruption involves death by spaghettification of a nearby star to a black hole
Spaghettification occurs when a star is devoured by a black hole
Astronomers can now better understand how supermassive black holes behave
The last moments of a star dying by spaghettification have been demonstrated in an artistic animation as scientists made a recording of what happens when a black hole rips a star apart when it gets too close. The phenomenon happened just 215 million light-years from Earth, making the scientists’ observation unprecedented.
By using the European Southern Observatory’s Very Large Telescope and New Technology Telescope, the Las Cumbres Observatory global telescope network and the Neil Gehrels Swift Satellite, a team of scientists was able to record a phenomenon called tidal disruption event.
In a study published in Monthly Notices of the Royal Astronomical Society, the team explained that tidal disruption involves death by spaghettification

If future civilizations wanted to study 2020, surely one “historical artifact” they would examine would be the viral supercut of Covid-19 commercials. As most of us have heard repeated ad nauseam, the phrase “these unprecedented times” highlights just how unpredictable the events of 2020 have been.
Among the many unforeseen challenges was the need to provide urgent, widescale access to services via digital channels. Millions faced a dire and immediate need for government assistance and the ability to quickly open new bank accounts or to find new employment virtually. At the same time, companies and municipalities were often delayed in providing for those needs due to a lack of quick onboarding solutions.
As we look back on the year, we must prepare for the next unprecedented moment in history,
Global companies spent around $15 billion extra a week on technology during the pandemic’s first wave, Harvey Nash/KPMG CIO survey finds.
Global IT leaders spent around $15 billion extra a week on technology to enable safe and secure home working during COVID-19, according to the 2020 Harvey Nash/KPMG CIO Survey. This was one of the biggest surges in technology investment in history— with the world’s IT leaders spending an additional 5% more of their IT budget to deal with the COVID-19 crisis, the survey said.
The technology leadership survey of over 4,200 IT leaders analyzed responses from organizations with a combined technology spend of over $250 billion. It also found that despite this huge surge of spending and security and privacy being the top investment during COVID-19, four in 10 IT leaders report that their company has experienced more cyberattacks.
AT&T and Verizon are worried about T-Mobile’s vast spectrum holdings and have asked the Federal Communications Commission to impose limits on the carrier’s ability to obtain more spectrum licenses. Verizon kicked things off in August when it petitioned the FCC to reconsider its acceptance of a new lease that would give T-Mobile another 10MHz to 30MHz of spectrum in the 600MHz band in 204 counties. AT&T followed that up on Friday with a filing that supports many of the points made in Verizon’s petition.
T-Mobile was once the smallest of four national carriers and complained that it didn’t have enough low-band spectrum to match AT&T and Verizon’s superior coverage. But T-Mobile surged past Sprint in recent years and then bought the company, making
