Today's #APOD is a #picture of the #nebula called #Thor's helmet. No, this #image is NOT produced by the #MARVEL studios, but really is an #astronomy object. Someone should ask Chris #Hemsworth if NGC2359 (the catalog name of this object) is his favorite nebula π Thor's Helmet read more: https://apod.nasa.gov/apod/ap221220.html 5 comments
@tiamat271 thatβs a question many people are wondering. I will let @MartialRelier (who did a pretty similar photo for #YourBestAstroPic2022) complete if needed. Unfortunately no, if you observe that #nebula with a relatively large #telescope, you wouldnβt see colors at all. The #eye are working at high-cadence so thereβs no time to collect enough photons each frame. You might distinguish vaguely the shape of the nebula if your telescope is large enough. @tiamat271 @MartialRelier Now you travel there with a rocket, you would see different colors. This image was taken with narrow band filters, like for many #nebula, but the eyeβs spectral response is quite different. You would see the same structure, but the colors would be different. @AlexSanterne |

@MartialRelier @AlexSanterne Wow, this is beautiful! I hope this is not a silly or dumb question, but when people share pics of nebulas like this, is that what it really looks like to the naked eye (as in, if I flew a magic spaceship to these places, would I see these beautiful colors all around me)? Or are the colors a representation of otherwise-invisible light/elements? Sincerely asking, because I donβt know. Thank you for sharing. π
