Comet C/2022 E3 (ZTF) Taken By Auvo Korpi On January 27 2023.
Comet C/2022 E3 (ZTF) taken by Auvo Korpi on January 27 2023.
During the formation of the sun, there was a protoplanetary disk (cloud of debris and gas) that orbited around it. The farthest parts of this disk were far from the heat emitted, and cooled down. The cold material clumped with frozen gasses and water, creating icy rocks.
These rocks orbit far away from the sun in huge elliptical orbits, in the Kuiper belt and Oort cloud. At one point, the icy rocks get closer to the sun. The ice is heated and releases dust, known as the comet’s trail.
Comet ZTF was first discovered in March 2022, but came closest to Earth in a long time in January of 2023. At first, the comet was believed to be an asteroid, but when it got closer to the sun, it was observed to have its signature green glow.
The green comes from the diatomic carbon, which is part of the comet’s atmosphere. As it got closer to the sun, the molecules became excited and radiate green light. This is also why the green color doesn’t extend to the tail, instead it is happening in the comet’s nucleus.
I remember going out with my telescope around this time to view the comet. At that point I think it was just above the Taurus constellation, and I had a lot of trouble angling the lens to point that high up.
I don’t remember being able to see the tail, but just with the naked eye, I could see the comet’s light. I can’t believe it’s already been two years since then. Time really flies.

Star Trails taken by Rob on February 24 2024
Star trails are photographs taken over long exposures, where the rotation of the Earth causes the stars to appear as arcs in the sky instead of points. The Earth rotates around its axis every 23 hours and 56 minutes.
Typically, star trails are focused on Polaris in the northern hemisphere, but I found this photo unique because it opted for a different composition. It also really highlights how dense the sky is with stars.
It begs the question, why isn't the sky infinitely bright with infinite stars? This is actually the observation that helped cosmologists find theories for the age of the universe. For a young universe, not enough time has passed for the light from incredibly distant stars to reach us, leading to the dark sky we see when we look up at night.

.. > 12dopmas challenge, Day 2
I made notes for one of my last year's math units (im repeating the exam) and I started making notes for this year's work
/
/
Did 2 pistol squats on each leg (seems very little but they're actually very difficult! or are for me anyway)
I finished a digital drawing I started a while back. I think it's just alright, no strong feelings about it but im glad I got it done
I forgot about the questions again but I will catch up on them!
130 days clean
Day 0
Floor time ✅️ // 🍊
✦ 6. 2. 25 ✦📓✦ Thursday ✦
I missed school (Physics and art especially!!) :) A friend told me that they like the exam phase better, because you have free days inbetween, but I honestly will take anything but that. I don´t care if I´m overloaded with work (that I can manage lmao) it´s chill. Anyway.
I´m doing (and will finish) my polish homework rn, so I guess that´s one of the things I did today. More are:
I ordered flowers to pick up for a bday party
Sketchbook page
Organised school to do´s
And I have now 5 "events" planned with different friends and it feels amazing. Finally time for that again!!
I just made a playlist of songs that I listen to while I study 📚 Unfortunately, I have to lock in over the holidays, and I know some people are in the same boat so hopefully this will help motivate!
I didn’t do this on purpose, but it turned out EXACTLY 2 hours long, so it’s a sign from the universe that you should listen to it 😁

I’ve had a pretty productive day – finishing it by reviewing this week’s plasma lectures :)
🎵Watershed Album – Opeth (finally moved on from my binge of the song Bleak like 10 times in a row, lol)
Friday, 21st March 2025
Moving onto my stellar remnants module today, with an appropriate soundtrack :)
🎵The Sky Moves Sideways Album - Porcupine Tree
SPRING IS HERE! 🌷💐🌸☀️
mental health, mood, weather, literally everything: 📈
my grades tho: 📉
my cat has arrived to wish you luck on exams! you can do it :)
The Soul Nebula taken by Kurt Wallberg on Februrary 1 2024
This image depicts The Soul Nebula (IC 1848) on the left and Westhout 5 (IC 1848) on the right. Westhout 5 is part of the bigger Soul Nebula. It’s an emission nebula— consisting of the star forming regions with ionized hydrogen gas and dark nebula. Dark nebulas are when the stellar medium is so dense that the light from objects behind it cannot pass through.
As you can see in the image, there are cavities in the gas. These were carved out by stars due to radiation and stellar winds. There is a theory of triggered star formation, which describes that these cavities compress the gas around it to trigger star formation. Images such as these have been used to help prove this theory, showing that the closer the star is to the cavity, the younger it is.
finally finished my online class!
and now i go back to regular school tomorrow…
