Variable Star Seen Pulsating By Hubble - Time-Lapse Video

Variable star RS Puppis was observed by the Space Telescope over a period of 5 weeks. These types of stars are unstable because they have consumed most of the hydrogen fuel. The pulsations seen are not moving gas, but light echoes.

How many millions of years is it going to do that oscillating back and forth as a variable star until finally decides it's going to become a red giant and blow up because it seems like something's preventing it from going to that stage like something got infused to it or something like that there's more fuel to get burned or something. As far as I know the instant the star supernovas that mathematically means it fused protons and neutrons to become lead. Then. In an instant he star collapses. It's outer layers and atmosphere bounce off the core of the star, the new white dwarf star, with the what, how much matter of the star, I don't know. It's simple though, you just subtract the amount of matter that forms a white dwarf from the total mass of the star. Where did all that matter go? It all turns into a nebula moving away from a center point because of expansion of the Universe. We haven't even slowed down. The universe is still accelerating because the big bang theory.

I would spend a lot more time on the actual time-lapse and less on all the CGI and artist renditions. From the comments, most people can't even find the most important part of the video which is just a couple seconds hidden deep in several minutes.. To me, the time-lapse did not look remotely like gas expanding. It looked like a spherical light intensity front that was propagating outward illuminating the dust.

QUESTION: considering the gas around the star, should there be planets around it that have not been engulfed by the expansion of it's outer layers, could they be visible as a dark spot, in short, could planets pertaining to that system be visible to Hubble??

What's the first thing she says? I couldn't understand it.

[codyoftheinternet]

Beautiful. Although it’s name “puppis” makes me feel dirty. Like how many women tell me they feel about the word “moist”.

Looks like v338 mon aint it? Or... Nibiru? Haha

[Camilo]

Should have watched the entire thing before commenting -_-

[abyvs]

Im just trying to make a slideshow for my astronomy class whats with all the conspiracy theorists

[seachangeau]

Oh this is such rubbish! Our sun varies its brightness over a 22 year cycle for pitys sake.

[kpn]

Are you folks serious?? Now we are to believe that light "echoes"? Hahaha, what is this CGI, "artist's depiction" garbage?! Where are the real images of stars from the hubble telescope?
