The brilliant flash of an exploding star’s shockwave—what astronomers call the “shock breakout” — is illustrated in this cartoon animation. The animation begins with a view of a red supergiant star that is 500 times bigger and 20,000 brighter than our sun. When the star’s internal furnace can no longer sustain nuclear fusion its core to collapses under gravity. A shockwave from the implosion rushes upward through the star’s
Leicester City (pronounced Les-ter), or the Foxes, are a relatively insignificant team. They are often fighting for a mid-table place in the Premier League, just as often slugging it out in lower leagues.
“This is a case where you can be so right and yet so wrong,” says Nestlé CEO Paul Bulcke. “We were right on factual arguments and yet so wrong on arguing. It’s not a matter of being right. It’s a matter of engaging the right way and finding a solution.” He adds: “We live in an ambiguous world. We have to be able to cope with that.”
Where exactly are the words in your head? Scientists have created an interactive map showing which brain areas respond to hearing different words. The map reveals how language is spread throughout the cortex and across both hemispheres, showing groups of words clustered together by meaning. The beautiful interactive model allows us to explore the complex organisation of the enormous dictionaries in our heads.
The accident on 26 April 1986 contributed to the downfall of the Soviet Union, changed the way the world thinks about nuclear energy and has affected an unquantifiable number of people in the region.
But when her colleague, Rodrigo Moura of the Federal University of Rio de Janeiro, dredged small areas near the shelf that day in 2012, he uncovered one of the most surprising finds in modern sea research–an extensive deepwater reef system up to 120 kilometers offshore, below the Amazon’s thick, dirty plume.
Ms Parcak looked at modern-day plant cover to find places where a possible Viking settlement had altered the soil by changing the amount of moisture in the ground. This was a technique she had previously used in Egypt.
After identifying a potential site, archaeologists found a hearth-stone, which was used for iron-working, near what appeared to have been a turf wall.
Two of his biggest ideas were about how space and time work. This thing you’re reading right now explains those ideas using only the ten hundred words people use the most often.1 The doctor figured out the first idea while he was working in an office, and he figured out the second one ten years later, while he was working at a school. That second idea was a hundred years ago this year. (He also had a few other ideas that were just as important. People have spent a lot of time trying to figure out how he was so good at thinking.)
