I need at least binoculars in my area ( I absolutely love my binoculars for viewing space ). Trying to find it with my telescope was tough.

I used the constellation right under it. I think it’s called andromeda, it looks like V. I used the set of 2 stars under the galaxy and follow up.

I live in an area of moderately dark skies, and can just make out the Andromeda Galaxy by eye - and only if I have it just off the center of my vision.

I use a couple of stars from the Andromeda constellation to find it, though Cassiopeia helps too.

Key word: apparent. Actual doubling of sound pressure levels is every 3dB. Every 10dB added is 10x the energy. (Sound energy and volume are two different things but they’re directly proportional)

Honestly surprised that it’s only 136 dB around the rocket. Also surprised that they didn’t also state the C-weight, as that would highlight more of the low end you get from the rocket itself. There’s a ton of low end that’s being tossed out (for good reason) when they A-weight.

actually... its a dance of life :-)

If you look at the above image you see a blue hue, and even some bright blue areas: that is all star formation of new hot blue (O& B) type stars... billions of them. And that all occurs because of the collision.

This one always fucks me up. I've heard and understood the explanation many times, but my human brain just doesn't like dealing with time dilation and numbers that big for some reason.
