Stunning cosmic display !
Stephan’s Quintet !
The topmost four of these five galaxies (known together as Stephan’s Quintet) are quite near Earth in cosmic terms, ranging from 40 million light-years away to 290 million light-years.
Their close proximity, shown in unprecedented detail with a JWST image, allows astronomers to more easily witness the merging of and interactions between galaxies. An array of images from JWST is spurring new questions about galaxy evolution.

Fastest star in the galaxy clocked at 2285 kilometres per second
Astronomers have spotted white dwarfs moving faster than any free-moving star seen before – so fast they must have been launched by supernovae
The white dwarf on the right is stealing matter from a neighbouring star. It will eventually explode as a type Ia supernova, propelling its companion away

“Earendel” (“Morning Star”)
Hubble Space Telescope just found the farthest individual star ever seen to date!
This star existed within the first billion years after the universe’s birth in the big bang. Earendel is so far away from Earth that its light has taken 12.9 billion years to reach us, far eclipsing the previous single-star record holder whose light took 9 billion years to reach us.
Though Earendel is at least 50 times the mass of our Sun and millions of times as bright, we’d normally be unable to see it from Earth. However, the mass of a huge galaxy cluster between us and Earendel has created a powerful natural magnifying glass. Astronomers expect that the star will be highly magnified for years.
Earendel will be observed by NASA’s James Webb Space Telescope. Webb's high sensitivity to infrared light is needed to learn more about this star, because its light is stretched to longer infrared wavelengths due to the universe's expansion.

These galaxies are in the process of merging and will eventually form the core of a massive galaxy cluster.

“Fire and Fusion,”
A portrait of the Earth’s sun by Andrew McCarthy, November 29th at 2pm from astrophotographer’s backyard in Arizona.
McCarthy layered approximately 150,000 images of the sun to capture the intricate details of our closest star.

Crescent Nebula in HOO
This nebula was discovered by a fellow named William Herschel, a British astronomer and composer. He did a lot of research on double stars and is most famously known for discovering the planet Uranus which at the time was the first planet discovered in a thousand years.
William Herschel was a self taught Astronomer, who built his own telescopes. He and his sister would make these mirrors by painstakingly polishing a piece of metal until it was extremely reflective, the largest of which is the Great Forty-Foot telescope with a focal length of about 12000mm.
