Search up the zoom of a Nikon p1000 and you will see what stars really look like and why they twinkle like that

Very nicely explained ... but wait! So, the stars twinkle, but then why don't planet's twinkle? Long, long ago, so long ago, I don't remember how long ago ... I was taught ... that stars twinkle and planets have a steady glow. Why is that?

Another question: are there any planets beyond the solar system that are visible from earth to an average human being with a hobby telescope?

Could stars move across the night sky in front of your eyes?? Like real time?? I was out at night and saw 25+ stars moving in front of my eyes in a matter of minutes.

bravo :) good mama :D i dont like some fake video, this is very nice explain

QUESTION: What is one scientific proof (validated through the scientific method) that the earth 🌍 is a spinning globe?
Thanks 🙏

If it's the atmosphere they why does one star flash and another right next to it doesn't?

[langstonmorris]

I thought the reason stars twinkle was because of sound and water and that's the stars are attached to the firmament which is the sky

If the Earth is spinning and stars are fixed, why am I seeing Orion going one way but the big Dipper moving another? Orion is moving towards my right while the big Dipper move from behind me towards the location of where Orion once was, then hours later moving towards my right. If they are exactly as you say they shouldn't do that. Yes I've seen stars move left, right up and down too and then move. I think their doing what you think their doing without disruptions as your describing. Then I see stars free from clusters which are bright moving in many directions sometimes at a fast past not in sync with any of the stars. I've also seen the moon do all it's phases night or day despite of the sun's location. This shows the moon is not reflecting light at all, rocks don't reflect light and glow, and the moon shouldn't be able to go through all phases despite having the same location yet not having the same result at it's phase. Your either been lied to or your not telling the truth about things you can notice in just 2 weeks worth of true actually study of this subject. I also know from long amount of years of study that the Earth is not spinning, the stars are moving around us. If you test the model as they presented it fails and the math of certain constants and physics fail.

what if the Earth is flat and we are on a fixed plane and the stars are rotating around us? those crazy Flat Earth people have been posting some pretty interesting information...

[leighsimpkins]

Hang on!!.... the stars are not fixed they move because if earth is the centre of gravity it is impossible for the earth to spin. It's earth that doesn't move not the stars, stars move, sun moves, moon moves around earth but don't spin

Could the twinkle of a star be so great that it looks like it is moving?
