Eskimo Nebula NGC 2392. (Credit: Andrew Fruchter (STScI) et al., WFPC2, HST, NASA) It was discovered by William Herschel in 1787. We now know that it's a planetary nebula, one that firns when a sun-like star, at the end of its life, loses its outer layers. It's about 1/3 of a light year across and located 3000 light years away in the constellation Gemini. Mona Evans, “Nebulae” http://www.bellaonline.com/articles/art43407.asp
Astronomy Picture of the Day for 13 Jul 2014. NGC 2818 is a beautiful planetary nebula, the gaseous shroud of a dying sun-like star. It could well offer a glimpse of the future that awaits our own Sun after spending another 5 billion years or so steadily using up hydrogen at its core, and then finally helium, as fuel for nuclear fusion.
Planetary nebulae can look simple, round, and planet-like in small telescopes. But images from the orbiting Hubble Space Telescope have become well known for showing these fluorescent gas shrouds of dying Sun-like stars to possess a staggering variety of detailed symmetries and shapes.
Barred Spiral Galaxy NGC 1300 (Mar 25 2012) Image Credit: Hubble Heritage Team, ESA, NASA Big, beautiful, barred spiral galaxy NGC 1300 lies some 70 million light-years away on the banks of the constellation Eridanus. This Hubble Space Telescope composite view of the gorgeous island universe is one of the largest Hubble images ever made of a complete galaxy. NGC 1300 spans over 100,000 light-years and the Hubble image reveals striking details of the galaxy's dominant central bar(...)…
