NGC 2359, also referred to as Thor's Helmet, is an emission nebula in the constellation Canis Major. At the heart of this nebula is a Wolf-Rayet star WR7, which is in this phase briefly before a supernova occurs.

The bubble appearance of this nebula is due to the strong stellar winds coming from WR7. These winds contribute to forming a complex structure, with a huge mass of ionized material. The high energy radiation coming from the star ionizes hydrogen to produce red light and doubly ionizes oxygen to produce blue light.

The gas absorbs and then reemits this light, leading to the name of "emission nebula".

NGC 1316 Taken By Hubble Space Telescope On January 26 2021

NGC 1316 taken by Hubble Space Telescope on January 26 2021

NGC 1316 is an elliptical galaxy formed by the collisions of multiple galaxies near the constellation Forax in the southern hemisphere. What makes this galaxy unique is the dark lanes of dust visible around the galaxy. These are indicative that they galaxies NGC 1316 was formed by were spiral galaxies.

What helped scientists determine that this galaxy was created due to a "recent" collision where different types of images taken of NGC 1316. Hubble's images helped to reveal huge collisional shells and a small number of globular clusters. Collisional shells are formed from debris of the parent galaxy, which under the effects of gravity and tidal forces. These tails last for a long time, before eventually being reabsorbed into the progenitor (object of origin). Globular clusters are a group of stars bound by gravity.

These two events were indicative of a merger that occurred within the past couple billion years.

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)

you ask a student in april how they're doing and they'll say "oh i'm fine" but in reality they are treating themselves in such a way that violates the geneva convention on treatment of prisoners

Pretty Winter Sunset But I’m Stuck Inside 🌅 Just Cleaned My Room Though So I Don’t Mind That Much.

Pretty winter sunset but I’m stuck inside 🌅 Just cleaned my room though so I don’t mind that much.

3rd picture is my desk— should I put something on the wall? I don’t want to drill anything in.

Today was pretty frustrating for a variety of reasons, so I didn’t think I would get much done today but then I hopped on to Tumblr and saw a bunch of people’s study posts so I guess I’m trying this again.

- Study for math test

- Work on research program applications

- Upload a new software onto my computer

Good luck 👍

.. > 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

Rosette Nebula Taken By Suzanne Beers On January 29 2024

Rosette Nebula taken by Suzanne Beers on January 29 2024

The Rosette Nebula is part of the Milky Way Galaxy and is located 5,000 light years away from Earth. The Rosette Nebula is an emission nebula (not to be confused with planetary nebula).

These kinds of nebula are formed around massive, hot stars, whose ultraviolet radiation ionizes the surrounding gas. The excited atoms in the nebula also emit radiation, causing the nebula's glow.

The Rosette Nebula is also home to star forming regions, as observed by the Chandra X-ray Observatory. These are especially concentrated in the bottom of the nebula, although it is difficult to see in this image. Note that this photo uses the Hubble color palette.

NGC 2403 Taken By John C. Yu On January 30 2024

NGC 2403 taken by John C. Yu on January 30 2024

NGC 2403 is a intermediate spiral galaxy. There are typically two types of spiral galaxies: barred and regular spirals. This galaxy falls between the two, denoted as SAB.

The bar in spiral galaxies forms due to gravitational instability. However, this bar can help with star formation as it funnels material to the center of the galaxy.

Interactions with neighboring galaxies or having greater instability can lead to a greater bar shape in the galaxy. However, dark matter halos also play a big role in having the opposite effect, often preventing the bar from forming. These combined factors lead to the median shape of this galaxy.

Intermediate spiral galaxies can eventually evolve into either regular spiral galaxies or barred spiral galaxies, but we won't be there to see the final form of NGC 2403.

55/100 days of productivity!

so, my chronic pain is back after a short break... which means I literally can't do the things I need to do... anyway let's get a good day in...

I accept myself exactly as I am in this moment. My worth is not determined by my productivity or my pain. I am enough, just as I am. Every small step I take today is a victory. Progress is progress, no matter how small. I am doing my best, and that is always enough.

to-do: 1.2.25

Morning yoga

mental health check _journal

Go to the mall

Writing session 1

Reading 2P _opt

Pain makes it hard to work effectively Falling behind creates anxiety Anxiety increases muscle tension Increased tension worsens pain Worse pain makes work even harder More falling behind... and the cycle continues And each loop of this cycle can make you feel more stuck and hopeless, which adds another layer of stress. It's not just in your head - this is a very real physiological and psychological pattern.
