"NGC 7000 in narrowband"
This galaxy looks quite special. That’s because the bright central region of NGC 289 is only about 3 arcminute in diameter while the extensive and faint outer arms extend the the size of the galaxy out to 14 arcmin across. That’s 300,000 light years across and it’s pretty huge as it’s more than twice the size of our own galaxy Milky Way.

The Milky Way, that galaxy that our solar system is in, is a barred spiral galaxy, so looks something like this

Figuring out that the Milky Way is this shape wasn’t easy since we’re in the galaxy and can’t see the whole thing. But astronomers already knew from looking at other galaxies that stars live along those spiral arms, which you can see above, so by mapping our galaxy’s stars’ emission of neutral hydrogen, it was found that the Milky Way had these arms.
At the middle of the galaxy there’s a central bulge that all spiral galaxies have. This was observed in the Milky Way too, so, by including the results of other observations, it was found that we live in a barred spiral galaxy.
R Sculptoris and its hidden companion
This new NASA/ESA Hubble Space Telescope image shows a star known as R Sculptoris, a red giant located 1500 light-years from Earth in the constellation of Sculptor. Recent observations have shown that the material surrounding R Sculptoris actually forms a spiral structure — a phenomenon probably caused by a hidden companion star orbiting the star. Systems with multiple stars often lead to unusual or unexpected morphologies, as seen, for example, in the wide range of striking planetary nebulae that Hubble has imaged.
R Sculptoris is an example of an asymptotic giant branch (AGB) star. All stars with initial masses up to about eight times that of the Sun will eventually become red giants in the later stages of their lives. They start to cool down and lose a large amount of their mass in a steady, dense wind that streams outwards from the star. With this constant loss of material, red giants like R Sculptoris provide a good portion of the raw materials — dust and gas — used for the formation of new generations of stars and planets. They also show what is likely to happen to the Sun in a few billion years from now, and help astronomers to understand how the elements we are made up of are distributed throughout the Universe.
R Sculptoris itself is located outside the plane of the Milky Way and is easily visible using a moderately sized amateur telescope. In this part of the sky far from the galactic plane, there are relatively few stars but many faint and distant galaxies can be seen.
The black region at the centre of the image has been artificially masked.

I’m pretty sure this is a giant eye in space
Sharpest View of the Andromeda Galaxy, Ever.
The NASA/ESA Hubble Space Telescope has captured the sharpest and biggest image ever taken of the Andromeda galaxy — a whopping 69,536 x 22,230 pixels. The enormous image is the biggest Hubble image ever released and shows over 100 million stars and thousands of star clusters embedded in a section of the galaxy’s pancake-shaped disc stretching across over 40,000 light-years.

whoa
Here’s Centaurus A (NGC 5128), a galaxy that’s between 10-16 million light years from us and is the 5th brightest galaxy in the sky. It’s debated what type of galaxy this is, it’s either a lenticular galaxy or an elliptical one. I hope it’s lenticular because that’s a really cool word.

everyone should follow this blog it’s great
also here is the full video
NGC1097 is a freaking wonderful galaxy I mean just look at
wow
It’s a Seyfert galaxy, which is a type of active galaxy, and you can tell this because its centre is so much brighter than the rest of the galaxy. That’s because there’s a black hole there letting out a load of light from all over the electromagnetic spectrum
