Man dives head-first into a flying swim cap in glorious slow motion


After two long years, Dan has finally returned to The Slow Mo Guys -- and he's picked up exactly where he left off. Ever the half of the YouTube duo to get stuck into new experiments, Dan's first stunt back was to attempt to put on a swim cap in mid-air by diving into it head-first. Needless to say, it took him more than a few attempts -- but his friend and partner Gav was right there behind the camera to capture all of them in extreme slow motion. Will the technique ever catch on at an Olympic level? But it certainly makes for an entertaining 12 minutes of viewing.

Man pops his way out of a giant bubble in glorious slow motion


If that's not a recipe for some enjoyable YouTube content, we don't know what is. In the clip above Gav and Dan from The Slow Mo Guys team up for their latest slow motion venture, with Dan perching on a saucepan while Gav creates a bubble around him by lifting up a giant, homemade hoop coated in soapy liquid. The results, as usual, are mesmerising.

Why Rotation Makes No Sense Sometimes - Facts So Romantic


The basic picture is clear enough: One body is at rest, while the other follows some circular or elliptical path around it. The trouble is just to figure out which body is which. If you're standing on the surface of the earth, it appears that the sun slowly orbits around you once per year. But we are thinking about the motion of the sun relative to the rest of the sky, which happens on a yearly cycle.) But on the surface of the sun, it would presumably also look as if the earth orbits around you once per year.

Two stars with an odd wobble are stretching space and time around them

New Scientist

A pair of distant stars have a weird wobble to their orbits, which is probably caused by a strange effect predicted by Einstein's theory of general relativity. This tumbling motion tells us that they formed in a very unusual way. Pulsars are dense neutron stars that emit beams of light. As they spin, those beams sweep across the sky, so we only see pulsars when their beams pass over Earth. PSR J1141-6545 is one such object, and it orbits a stellar corpse called a white dwarf, which formed when a lower-mass star ran out of fuel and lost its outer layers.

Hubble captures gorgeous shot: Crab Nebula's pulsing 'heart'

Christian Science Monitor | Science

The Hubble Telescope has captured another stunning image of outer space with its photograph of the heart of the Crab Nebula, a pulsing neutron star surrounded by swirling clouds of rainbow-colored gas. The Crab Nebula was created by a supernova, or the explosion of a massive star, the remnants of which remain at the center of the nebula in the form of a neutron star: a fast-spinning, compressed ball of subatomic particles called neutrons. "The neutron star is a showcase for extreme physical processes and unimaginable cosmic violence," wrote NASA in a statement. "Bright wisps are moving outward from the neutron star at half the speed of light to form an expanding ring. It is thought that these wisps originate from a shock wave that turns the high-speed wind from the neutron star into extremely energetic particles."
