Elon Musk: "3 months ago, we started building a massive water-cooled, steel plate to go under the launch mount. Wasn’t ready in time & we wrongly thought, based on static fire data, that Fondag would make it through 1 launch. Looks like we can be ready to launch again in 1 to 2 months."

Milky Way Core from Florida's Forgotten Coast

According to Google the universe is estimated to be 13.7 billion years old, but 98 billion light-years wide, how do we know this if the furthest distance we could possibly see is 13.7 billion lightyears??

What am I missing here? The light from anything further than 13.7 billion light-years couldn't have reached us so how could we see it. And nothing travels faster than light so what else could we possibly be using to detect stuff further than that. I imagine you could do the math on how the gravity of some really far galaxy interact with eachother to predict some potential galaxys a little beyond 13.7 billion light-years but I don't get how you could see 98 billion light-years of universe. Am I missreading something or am I just not understanding?

Not what I expected at all

Hello everyone! I recently took a trip up to a Bortle class 1 sky in the Bruce Peninsula (Ontario, Canada). I went there with the prime purpose of enjoying the night sky in all its glory. The problem is that it was nothing like what was described by the Bortle scale or what you typically see in photos. Don’t get me wrong, I was sobbing at the beauty; but it i also found it a little disappointing that it was nothing like the photos after spending 3 hours in the dark, cold and dangerous night trying to dark adapt. I think it might have been because of a few factors: 1. The transparency and seeing conditions on the weather report (clear dark sky’s) read “average” 2. The Milky Way hadn’t risen (and it doesn’t seem like it will for a while) 3. I was in a parking lot so I didn’t have a full view of the horizon. Do you think these might be the reasons why I didn’t get that prime experience? Anyone have any suggestions on what I should do?

Is there a "correct" orientation for constellation depictions?

Sorry if this is really dumb but I'd love a constellation tattoo but am suddenly worried about which way to orient it. In my head, you can't go wrong whichever way it's depicted in imagery but is that true? Maybe it's a hemisphere difference?

Can i reach focus

Can i reach focus with eighter 224mc or 462mc with my starquest 130P (650mm focal lenght) and if not what can i do to reach without a barlow)

Hubble Spots Super Massive Black Hole Ejection

This Hubble Space Telescope archival photo captures a curious linear feature that is so unusual it was first dismissed as an imaging artifact from Hubble's cameras. But follow-up spectroscopic observations reveal it is a 200,000-light-year-long chain of young blue stars. A supermassive black hole lies at the tip of the bridge at lower left. The black hole was ejected from the galaxy at upper right. It compressed gas in its wake to leave a long trail of young blue stars. Nothing like this has ever been seen before in the universe. This unusual event happened when the universe was approximately half its current age. Credits: NASA, ESA, Pieter van Dokkum (Yale); Image Processing: Joseph DePasquale (STScI)
