"Cannonball" pulsar points to the supernova that shaped it

Pulsars are superdense neutron stars formed from massive supernovae. They can only be found if their electromagnetic radiation points directly to Earth like a nuclear lighthouse. It has been found that pulsars rotate as fast as 1.6 milliseconds or 38,500 rpm. They absorb the angular momentum of the massive stars that formed them, but are only a fraction of the …

Ultima Thule is shaped like a snowman. Show detailed pictures: NPR

New images of a mysterious world in the vastness of our solar system show that it is shaped like a snowman and a large icy ball is attached to a smaller one. The shape indicates that there is a rotating cloud of innumerable little squirrels. Objects must have grown together into two spheres, which slowly contract closer and closer until …

Recent research has shown that tornadoes, unlike popular thinking, are shaped from the ground up

Historically, scientists assumed that the tornado rotation started in storm clouds and formed a funnel that moves down. This theory agrees with what storm hunters visually observe in the field. Viewers often report that funnel …

New evidence shows that tornadoes are not shaped as scientists have always thought

Historically it has been suggested that tornadoes originated in the clouds and that turbulent fingers reached the earth. Now a team of climatologists has shown that this top-down model of tornadogenesis could actually be wrong. Yep. Tornadoes, as their research has found, are formed from scratch. Tornadoes can form surprisingly quickly in a matter of minutes. For this reason, it …

How 70,000 years of human interaction have shaped an icon of wild nature – ScienceDaily

The evolution of the orangutan has been more heavily influenced by humans than previously thought, as new research shows. Professor Mike Bruford of Cardiff University was part of the team of scientists who illuminated the evolution of the Critical Endangered Species. Their findings provide new opportunities for orangutan protection. The orangutan is one of the living relatives of man and …

The asteroid that destroyed the dinosaurs also shaped the evolution of the birds

Scientists investigating plant life around dinosaur extinction have made a startling discovery: out of all the birds living at that time, only the bottom-living species survived. The finding in Current Biology shows how the avian winners and losers of the extinction of the Cretaceous paleogen influenced the evolution of all the birds we see today. The asteroid that hit Earth …
