nasa-official!!!!!! why is it that the Rosette nebula only appears red in some photos? Is that how it appears optically, or is that just how it appears in one of the spectra that we read it in?

Well whenever you see red in nebulae, thats typically due to hydrogen being excited. The Rosette Nebula is actually classified as an H II region. H II (singly ionized hydrogen) regions are caused by some source of energy, kicking the electron out of the hydrogen atom and keeping it out.

So Rosette is definitely red. To strengthen this effect, pictures are often taken using a Hydrogen-Alpha filter which (you guessed it) only lets the light in from this transition!!! But, sometimes people want to look at what’s going on in the nebula in different wavelengths too

Hey! I have to do a quick presentation (like 2 minutes, tops) about literally any topic for a nuclear science class. I was thinking something along the lines of radiation in space but I'm clueless. Any suggestions?

You could talk about nuclear fusion in the core of stars, and how stars don’t create elements heavier than iron because instead of creating energy through fusion it requires energy.

All elements heavier than iron are formed during supernovae. After a star dies, the energy can be transferred into creating heavier elements! Thank a dead star for your existence

10 Interesting Psychology Facts

1. Cognitive Dissonance - the idea that when we hold two conflicting thoughts or beliefs, we unconsciously adjust to make one fit with the other. My social psychology professor gave an example of a student who values studying all the time, but slacks off when it comes to their favorite television show. So the student tells herself that watching the television helps her study later when it really doesn’t. However, telling herself that helped her eased the anxiety.

2. Hallucinations are common - one third of people report experiencing hallucination at some point in time. Similarly, normal people often have paranoid thoughts. So when was the last time you hallucinated?

3. The Placebo effect - this is when you think that something like a drug has an effect on you when really it doesn’t. It’s your thoughts that actually resulted in you getting better.
