Just an incredibly daring diva doing her thing!🌳🪐👽🧚🏽♀️🌟
Singing lead in an intergalactic supernova band, yes please!🪐
“Exploring the cosmic beauty far beyond our galaxy, I’ve crafted my interpretation of alien life forms using the powerful AI of ChatGPT. This fantastical being represents the artistic blend of imagination and technology, embodying the diverse beauty that might exist light-years away. The vivid colors are my favorite part – they symbolize the vibrant, mysterious essence of distant galaxies. What do you think? Does this stir your imagination about the universe’s wonders? 🌌✨
Quiero una chica de otro planeta💚
Comparing the rotations of objects in the Solar System. Just look at them lol.✨🪐
To everyone that's confused, the planet Venus rotates very very slowly, with a single revolution taking about 243 Earth days, and Mercury rotates slowly, but not as slow as Venus.
The galaxies and stars
Ask me at last,
"Where have you been, dear?"
Numb but awestruck, lost in myself
I tell them,
"To a paradise, you might not know of."
"Not a chance!", they exclaim.
"We are here since forever,
Witnessed every bud flourish into a flower and every leaf decay into the soil."
"And you reckon a place, not in our books?"
"Was this "destination" of yours, a dream?"
Taken over by placidity, I say,
"Not a cloud, nor a stream, no trace of the slightest being,"
"It wasn't grand, wasn't sweet."
"But I was intrigued by myself,
And found a paradise within."
This is a photo of the Andromeda galaxy I took nearly 5 years ago. The dark parts of the galaxy are gigantic clouds of dust and gas in which no stars and planets are born. This galaxy is one the closest one to our own, and yet it's 2.55 million light years from us, It's composed of about 1000 billion stars, in a few billion years it will collide with our own galaxy.
The two lighter blotches around Andromeda are two satellite Galaxys that orbit around Andromeda and are also composed of millions of stars.
Those numbers are so big they start to get inconceivable, and that's only a small fraction of what exists out-there. We are not much in the grand scheme of the universe, but when you look at the night sky and the wonders of the universe you can feel at least for a little while that you're part of it.
This is M51, also known as the Whirlpool Galaxy it is a pair a galaxy currently interacting together. If you look at the two arms of the spiral, you will see that the one on the left is somewhat deformed (near the other galaxy) this is due to the gravitational interaction between the two galaxies. Those interaction are also the reason why the left galaxy (NGC 5195) is this irregular. Some of the models have proposed that both galaxies have passed through each other at some point in the past. In the future both galaxie will slowly fuse together, but this will take at least a few hundred million years. Multiple other interacting galaxies also exist, such as the butterfly galaxies or the antenna galaxies.
This photo was supposed to be a test of my new equatorial mount but the result was WAY BETTER than expected so here you go (the post-treatment of the photos is not the best ever but I had to work with a limited amount a data). I will probably post more photos this summer since I now have access to better skys and a better mount than in Munich (If the weather complies).
same picture with a better post treatment of the original data.
in astrophotography, a lot the work is in the post treatment step. that step does not add details or actual alter the actual data, it's all about how do you reduce the noise in the image as much as posible while keeping the data as visible as possible (in short a lot of math hidden behind what looks like simple fonction such as ''deconvolution'').

II took another photo of M51 / the whirlpool galaxy, same camera and same processing of the data, but I used a different (bigger) telescope. Here, using a bigger telescope has two major effects, firstly the image is more ''zoomed in'' since the focal length is longer. Secondly, since the diameter is bigger the maximal (angular) resolution of the image can be increased. This increase in resolution is due to the way the waves of light are diffracted by the aperture of the optical instrument (in short bigger aperture = better resolution). This increase in resolution is one of the reasons professional telescopes have gigantic mirrors and/or use telescope arrays combined with interferometry to increase their maximal angular resolution.
Finale got around to processing the photos of M33 I had taken at the end of august. M33 is a spiral galaxy about half the size of our own galaxy and located about 2.7 million light years from earth. This galaxy has a rather high rate of star formation resulting in numerous ionised hydrogen regions (the red irregular blotches inside the galaxy), some of those being notable enough to have been included in the NGC catalogue or the IC catalogue.
NGC 588 NGC 604 (Example of some of the notable nebula in M33)
On of the first recorded observation of this galaxy was possibly done by Giovanni B. Hodierna before 1654, it was independently rediscovered by Charles Messier in 1764 who added it to his catalog (hence the name Messie 33).
information on the photo - total exposure time : 1h48 min using RGB and Ha filters - camera : ASI294 mm - telescope : Newtonian 150/600 with 0.95x coma corrector - photo edited with pixinsight
For those using PixInsight for treatment/edition, I recently discovered the scrips created by Seti Astro (https://www.setiastro.com/pjsr-scripts), Blemish-Blaster was quite useful to remove the halos from my Ha filter and What's In My Image helped with the identification of nebulas. If you had not heard those scrips, you should check them out.
