Former triathlete and six-time Ironman champion Olivier Bernhard founded the Swiss company. On Running is the official name of the company, which was founded in 2010. Altra came in with the cushioned zero dropĪnd just like those other brands, it might take a few runs with the pods to get used to the different feel.HOKA came in with their high stack shoe.To break in to the shoe scene now, you need something new. On Cloud Running Shoesīut maybe you, like me, noticed that trying to just search ON or On running never quite got you where you wanted to go. Or make sure you read ON’s return policy, which is going to make it easy to test out running shoes and return if it’s not the right fit. But as always I encourage you to head in to a running store and put them on! Run around the shop and see what you think. There is no one perfect running shoe for all runners, so I’m going to share my findings. Over the last 10+ years, I have run in a bunch of On Cloud models. Let’s talk about On Cloud running shoes, what sets them apart and what to know before you buy. These features, the team suggests, could represent the outer layers of gas blasted out by the supernova - we are seeing this bit at an angle.Maybe your running partner has started raving out this shoe with bubbles or you’ve just seem them on more feet and started to wonder… what’s the deal. Additionally, The JWST spotted something new: Inside the main ring, where gas and dust forms a keyhole-shaped ejecta cloud, there are two puzzling arcs, or crescents. More diffuse emission in the form of a general glow is also seen as the blast wave from the supernova excites gas around the site of the explosion. The JWST has revealed new details on this front, showing that the shockwave has expanded beyond the main ring and reaccelerated to about 3,600 kilometers per second (2,236 miles per second) while producing new hot spots that may, with time, become as bright as those previously identified. Two other rings, which appear to be in a different plane to the main ring as well as thinner and more faint, are more mysterious astronomers have speculated these rings could be where the star’s stellar wind, emitted before the supernova, interacts with material the star previously ejected.Īlternatively, they could be getting illuminated by jets from an unseen neutron star which experts believe must have formed alongside the supernova explosion. As the wave clashed with this ring, it slowed to about 2,300 kilometers per second (1,430 miles per second).Ĭlumps within this ring gradually brightened, appearing as a bracelet of pearls. The Hubble Space Telescope has previously watched as Supernova 1987A's expanding shock wave, initially traveling at about 7,000 kilometers per second (4,350 miles per second), caught up to and collided with a ring of circumstellar debris ejected by the doomed star during the 20,000 years or so before it went supernova. When massive stars, such as blue supergiants, near the end of their lives, they become unstable and begin throwing off large amounts of matter. Matsuura’s project used the JWST to measure the expanding supernova's shockwave as that wave interacts with surrounding material. Now, the JWST has been brought to bear on the supernova’s remnant in a study led by Mikako Matsuura of Cardiff University, in the UK, resulting in this spectacular image of a dead star's aftermath. So bright was this supernova, in fact, that it was visible to the naked eye in the southern hemisphere - and astronomers have been tracking its expanding debris ever since.
