This is an artist’s concept of the fastest rotating star found to date. The massive, bright young star, called VFTS 102 rotates at about two million kilometres per hour. Centrifugal force from this dizzying spin rate has flattened the star into an oblate shape, and spun off a disk of hot plasma, seen edge on in this view from a hypothetical planet. The star may have “spun up” by accreting material from a binary companion star. The rapidly evolving companion later exploded as a supernova. The whirling star lies 160 000 light-years away in the Large Magellanic cloud, a satellite galaxy of the Milky Way.

“One of the most actively changing areas on Mars are the steep edges of the North Polar layered deposits. This image from NASA’s Mars Reconnaissance Orbiter (MRO) shows many new ice blocks compared to an earlier image in December 2006. An animation shows one example, where a section of ice cliff collapsed. The older image (acquired in bin-2 mode) is not as sharp as the newer one.” Credit - nasa.gov

As the Fog Rolls In

Although we talk about fog rolling in, it’s rare for us to have a perspective where we can truly appreciate that flow. But this photograph from Tanmay Sapkal provides just that for the low summer fogs sweeping over Marin, CA. (Image credit: T. Sapkal; via NatGeo) Read the full article
