Hand Of God Nebula 👌🏾
This phenomenon, dubbed the 'Hand of God' is known as a pulsar wind nebula. It is powered by the remnant, dense core of a star that exploded in a supernova explosion. ...
The pulsar, known as PSR B1509-58, is about 19 kilometers (12 miles) in diameter and it's spinning around almost 7 times per second!

Ce fragment d’un rouleau de papyrus constitue l’un des plus anciens témoignages d’une édition grecque de l’#Odyssée datant de la fin du IIIe siècle avant JC. Il a été trouvé en réemploi pour le cartonnage d'une momie à Gorhan en Egypte , à 35 km au sud-ouest du Fayoum.
Le rouleau comporte deux chants entre la fin de l’épisode du Cyclope et le début de celui d’Éole.
Conservé à la BNF .
Is this what will become of our Sun?
Quite possibly. The first hint of our Sun's future was discovered inadvertently in 1764.
At that time, Charles Messier was compiling a list of diffuse objects not to be confused with comets.
The 27th object on Messier's list, now known as M27 or the Dumbbell Nebula, is a planetary nebula, one of the brightest planetary nebulas on the sky and visible with binoculars toward the constellation of the Fox (Vulpecula).
It takes light about 1000 years to reach us from M27, featured here in colors enhanced by red for hydrogen and blue for oxygen.
We now know that in about 6 billion years, our Sun will shed its outer gases into a planetary nebula like M27, while its remaining center will become an X-ray hot white dwarf star.
Understanding the physics and significance of M27 was well beyond 18th century science, though. Even today, many things remain mysterious about planetary nebulas, including how their intricate shapes are created.
