Black holes

13 Upvotes

I guess this isn’t really a question, but I was just thinking, by no means am I an astronomy nerd, I know absolutely nothing about space. But I was just thinking about how cool black holes are, they, along with a lot of things in space, go against everything I’ve ever learned about how physics work, and I’m just in awe about all of space, I can’t even, it’s an inexplicable feeling, just knowing how. time, light bends and distorts in the presence of a black hole just is awesome, I know this isn’t. A coherent thought but I just needed to say it

Astronomy Astrophotographers, how do you store and back up your photos?

Do you save them on local hard drives, external drives, a NAS, or a cloud storage service? Which storage method or cloud service do you use, and what would you recommend for keeping large RAW files safe?

Planetary Science if a TNO larger than Mercury were to be found would the IAU consider updating their definition of a planet?

0 Upvotes

Let's say a planetary body similar to Ganymede were found orbiting the Sun between 50 and 250 AU. Would this be enough to sway the IAU into holding another vote?

What about if it were slightly more massive than Mercury? This would make it a little larger than Mars assuming a similar density to Eris.

EDIT: To be clear I am not asking if it would meet the current definition of a planet. I am asking if the discovery of a planetary body larger than Mercury or Mars in the Scattered Disc would motivate the IAU to reconsider the current definition.

Maybe this video is a better example. What are these?

I'm posting this to show these are the same thing as my other video but nobody seems to be going into the comment section to watch it. They are absolutely not stars, they move completely different than the planets the and stars. They are definitely not a planet and I thought I just got the best shot of Neptune and Triton or Proteus but definitely not, I wish but no. This is a little before the time when the orbs were all over new Jersey and I believe it may have been whatever those things were just on their way here. This video shows a couple but what a shade of blue.

Astronomy How do we see the Big Bang's Light?

0 Upvotes

From what I understand of The Big Bang, we know the rough age of the universe and how it was explained to me is that when the big bang happened everything exploded outwards. My question is how are we still seeing that light if everything exploded outwards from the big bang however nothing moves faster than light? How would we be in position to see the traveling light if we weren't here first?

Bright flash in sky tonight

0 Upvotes

Curious to know if anyone else saw this or maybe knows the cause-

Approx 2:05am MST, just to the left of the star that is the tail end of Cassiopeia, I saw a bright white flash of light. It happened just once and it was MUCH larger than any of the surrounding stars. Large enough that I thought for a split second it was an airplane light. It was literally as if someone turned a light on and off. There are no visible stars in that area to the naked eye but my Sky Map app does show 2 very tiny stars in that area.

Just curious if anyone else saw it and if it could have been a starburst?? It was just so bright and then... Gone
