True.
Iron actually takes more energy to fuse than it releases, so the inward pressure needed to keep the star from collapsing isn’t enough when it’s mainly fusing iron, and then it collapses.

When Stars Die…….
Wow, that’s gorgeous :o
That’s gotta be one of the most beautiful nebulae I’ve laid eyes on! And, it looks like a heart too!

IC 1805: The Heart Nebula : What energizes the Heart Nebula? First, the large emission nebula dubbed IC 1805 looks, in whole, like a human heart. The nebula glows brightly in red light emitted by its most prominent element: hydrogen. The red glow and the larger shape are all powered by a small group of stars near the nebula’s center. In the center of the Heart Nebula are young stars from the open star cluster Melotte 15 that are eroding away several picturesque dust pillars with their energetic light and winds. The open cluster of stars contains a few bright stars nearly 50 times the mass of our Sun, many dim stars only a fraction of the mass of our Sun, and an absent microquasar that was expelled millions of years ago. The Heart Nebula is located about 7,500 light years away toward the constellation of Cassiopeia. Coincidentally, a small meteor was captured in the foreground during imaging and is visible above the dust pillars. At the top right is the companion Fishhead Nebula. via NASA
Okay I love the Big Bang Theory (as in the actual scientific theory about the start of our universe) but also the TV show.
(Sheldon was my favorite)
Anyway I didn’t know there was a full version of the theme song and I really like it :)

Max Planck, you absolute boss
Btw there’s always something left in physics to discover. Going from nothing left to discover to quantum theory is a huge leap though, because quantum has PLENTY to figure out.

Neptune!
Mercury will always be my favorite planet (closest to the Sun, underappreciated, proved Einstein’s general relativity, among other things) but I think Neptune’s the most beautiful. Look at that hue!

neptune.
I mean, the song really isn’t accurate.
Also that’s a bit unfair. I’m pretty super that’s a Red Super Giant. Not all stars are that huge xD (even though I’d wouldn’t describe any star as “little”)

Little star : am I a joke to you?
When can I move???
That’s so gorgeous though. I hate artificial lighting. These pictures seem so extraordinary and gorgeous but most people don’t know that the sky EVERYWHERE is gorgeous but our lighting just ruins it.
I remember one time when I went out in the middle of Arizona and I could just barely see the Milky Way. It’s quite a sight. I wish we were able to see it every night.

This is a nice little website which I used to outline my Life of a Star series.
It’s got some good info if you want a little brief course on stars (though my series is definitely way more detailed).

Lookin’ Good!
I’ve been wanting to be an Astronaut for Halloween but sadly I live in Florida and the heat might suffocate me in a full suit! Perhaps a nice NASA shirt and hat and maybe a fake ID badge and I can go as a scientist :D
