The nebula extends about 0.06 parsecs (0.20 light-years) from its center. [5] As early as 1974, the central star was known to be among the coolest carbon -sequence (type WC) Wolf-Rayet stars. [ 12 ] The nebula has a mass of 0.08 M ☉ [ 7 ] and an electron temperature, that is the average kinetic energy of electrons within the plasma , of 8,160 ...
Gyulbudaghian's Nebula (gyool-boo-DAH-ghee-an) is a reflection nebula in the northern constellation Cepheus, located about 1.5 degrees west of the much brighter reflection nebula NGC 7023. The light illuminating it comes from the T Tauri star PV Cephei .
NGC 1763 (also known as N11 B, LH 10 or ESO 85-EN20) is an emission nebula with an embedded star cluster in the Dorado constellation in the Large Magellanic Cloud, It is very bright, very large and very irregular. Its apparent size is about 3.0-5.0 arcmin. [3]
The James Webb Space Telescope has revealed colorful new portraits of the iconic Ring Nebula that capture unprecedented details a dying star creates glowing structures. Stunning new images reveal ...
NGC 6826 (also known as Caldwell 15) is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "Blinking Planetary", although many other nebulae exhibit such "blinking". When viewed through a small telescope, the brightness of the central star overwhelms the eye when viewed directly, obscuring the surrounding ...

NGC 7129 is a reflection nebula located 3,300 light years away in the constellation Cepheus. A young open cluster is responsible for illuminating the surrounding nebula. [2] A recent survey indicates the cluster contains more than 130 stars less than 1 million years old. [citation needed] NGC 7129 is located just half a degree from nearby ...
