Other galaxies. Much farther away. The Andromeda galaxy is one of the relatively close ones. In fact, other than some dwarf galaxies, I think it's the closest large galaxy.

The other galaxies are fainter, and were mostly discovered only starting from the 1970s.

Lunar analemma:


https://old.reddit.com/r/interestingasf ... ledo_over/Photographic stack of the lunar phases obtained every day at the same time, plus 51 minutes of offset to compensate the Earth's translation, in a total period of 29.5 days, carried out at a distance of 8 kilometers from Toledo. This peculiar shape is due to the synodic curve formed by the inclined and elliptical orbit of our satellite, whose aspect changes gradually each lunar cycle.
Due to adverse weather conditions, some of these photos could not be taken during the same period as the rest, so they were obtained from a previous lunar cycle, and to achieve the position at the same time, several of them were taken during the day for what they were digitally treated to give them a nocturnal appearance. Also indicate that, to adapt it to the landscape, the relative dimensions of the complete analema have been reduced proportionally, but maintaining the aspect and the real size of the Moon in relation to the city, as observed at that distance.

Re: Cool astronomy photos
https://www.nature.com/articles/d41586- ... 479NdPP3E0The first-ever image of a black hole is now a movie
Pictures created from old observations show the void’s stormy evolution over the past decade.
The historic first image of a black hole unveiled last year has now been turned into a movie. The short sequence of frames shows how the appearance of the black hole’s surroundings changes over years as its gravity stirs the material around it into a constant maelstrom.
The images show a lopsided blob of light swirling around the supermassive black hole at the centre of the galaxy M87. To create them, the Event Horizon Telescope (EHT) collaboration — which harnesses a planet-wide network of observatories — exhumed old data on the black hole and combined these with a mathematical model based on the image released in April 2019, to show how the surroundings have evolved over eight years. Although it relies partly on guesswork, the result gives astronomers rich insights into the behaviour of black holes, the intense gravity of which sucks in matter and light around them.
“Because the flow of matter falling onto a black hole is turbulent, we can see that the ring wobbles with time,” says lead author Maciek Wielgus, a radio astronomer at Harvard University in Cambridge, Massachusetts.

One of our Solar System's most tantalizing worlds, icy Saturnian moon Enceladus appears in these detailed hemisphere views from the Cassini spacecraft. In false color, the five panels present 13 years of infrared image data from Cassini's Visual and Infrared Mapping Spectrometer and Imaging Science Subsystem. Fresh ice is colored red, and the most dramatic features look like long gashes in the 500 kilometer diameter moon's south polar region. They correspond to the location of tiger stripes, surface fractures that likely connect to an ocean beneath the Enceladus ice shell. The fractures are the source of the moon's icy plumes that continuously spew into space. The plumes were discovered by by Cassini in 2005. Now, reddish hues in the northern half of the leading hemisphere view also indicate a recent resurfacing of other regions of the geologically active moon, a world that may hold conditions suitable for life.

UPDATE: New measurements show moon has hazardous radiation levels
Say WHAT?

So, was there less radiation in 1969, or did all that jumping around and stuff help those dudes fight cancer...Future moon explorers will be bombarded with two to three times more radiation than astronauts aboard the International Space Station, a health hazard that will require thick-walled shelters for protection, scientists reported Friday.
If there was less radiation back then, what happened?
Is global warming to blame?
Inquiring minds want to know!
Then Skank Of America could start in...

↑ Not really fresh news, the whole of space is full of radiation (fast protons and hard UV from the Sun + cosmic rays, which can be anything), so we fragile meatbags better stay under our cushy atmosphere. And send robots.
https://apod.nasa.gov/apod/ap200922.htmlEquinox in the Sky
Does the Sun set in the same direction every day? No, the direction of sunset depends on the time of the year. Although the Sun always sets approximately toward the west, on an equinox like today the Sun sets directly toward the west. After today's September equinox, the Sun will set increasingly toward the southwest, reaching its maximum displacement at the December solstice. Before today's September equinox, the Sun had set toward the northwest, reaching its maximum displacement at the June solstice. The featured time-lapse image shows seven bands of the Sun setting one day each month from 2019 December through 2020 June. These image sequences were taken from Alberta, Canada -- well north of the Earth's equator -- and feature the city of Edmonton in the foreground. The middle band shows the Sun setting during the last equinox -- in March. From this location, the Sun will set along this same equinox band again today.

https://apod.nasa.gov/apod/astropix.htmlFilaments of the Cygnus Loop
What lies at the edge of an expanding supernova? Subtle and delicate in appearance, these ribbons of shocked interstellar gas are part of a blast wave at the expanding edge of a violent stellar explosion that would have been easily visible to humans during the late stone age, about 20,000 years ago. The featured image was recorded by the Hubble Space Telescope and is a closeup of the outer edge of a supernova remnant known as the Cygnus Loop or Veil Nebula. The filamentary shock front is moving toward the top of the frame at about 170 kilometers per second, while glowing in light emitted by atoms of excited hydrogen gas. The distances to stars thought to be interacting with the Cygnus Loop have recently been found by the Gaia mission to be about 2400 light years distant. The whole Cygnus Loop spans six full Moons across the sky, corresponding to about 130 light years, and parts can be seen with a small telescope toward the constellation of the Swan (Cygnus).

Re: Cool astronomy photos
This is one of the coolest discoveries I've ever seen...
https://apod.nasa.gov/apod/ap200929.html
It's a solar system with 3 stars. Besides being cool, it shouldn't even exist. There is a classic physics conundrum called the Three Body Problem.
https://en.m.wikipedia.org/wiki/Three-body_problem
Basically, the whole reason we only see single and binary solar systems is because three stars don't seem to form a stable orbit. One of the three quickly gets chucked. There are special and bizarre mathematical solutions to the 3 body problem, but this is the first real life example that I'm aware of.
The painfully brief paragraph about this system indicates that it could break apart in the near future, or that it may be in the process of breaking apart, but the fact that the system formed such beautiful concentric rings indicates that it has remained relatively stable for quite a long time. Would love to see more study on this system and would love to know if the orbits follow on of the mathematical 3 body solutions.

Re: Cool astronomy photos
Not to be pedantic, but I don't think the three body problem means that trinary star systems don't exist. It just means that it's difficult to predict how they will behave using Newton's laws of motion. Not impossible, but difficult.

HubbleESA
This video shows a unique time-lapse of the supernova in galaxy NGC 2525. The supernova is captured by Hubble in exquisite detail within this galaxy in the lower left portion of the frame. It appears as a very bright star located on the outer edge of one of its beautiful swirling spiral arms. This new and unique time-lapse of Hubble images shows the once bright supernova initially outshining the brightest stars in the galaxy, before fading into obscurity during the telescope’s observations. This time-lapse consists of observations taken over the course of one year, from February 2018 to February 2019.
NGC 2525 is located nearly 70 million light-years from Earth and is part of the constellation of Puppis in the southern hemisphere. Hubble captured this series of images of NGC2525 in 2018 as part of one of its major investigations; measuring the expansion rate of the Universe, which can help answer fundamental questions about our Universe’s very nature.
The whole galaxy for reference:
