“What is today but yesterday’s tomorrow?” Deep thoughts from the heart of a cosmic Krab, er, crab. 🦀⁣ ⁣ This close-up image of the Crab Nebula, originally released by NASAHubble in 2016, reveals the beating heart of one of the most deeply-studied remnants of a supernova—in other words, the aftermath of an exploded star.⁣ ⁣ The neutron star at the middle of the nebula (the rightmost of the two bright stars) is spinning 30 times a second, sending out pulses of radiation with clockwork regularity. The Crab Nebula, which first appeared in our skies about 1,000 years ago, is located about 6,500 light-years from Earth.⁣ ⁣ Image description: Stars and gas swirl through a misty image of the cosmos. Orange-red bands circle the outside of the image and snake through its middle; a handful of bright white stars are scattered throughout, especially just right of center.⁣ ⁣ Credits: NASA and ESA⁣ ⁣ #NASA #Space #Universe #Hubble #CrabNebula #Astrophotography #MrKrabs
