Hi all, Sorry if this has been asked before but every time i do research in to this i get different answers from different sauces. Not sure if im looking at out dated information or not so im hoping if i ask my questions here i can get the most up to date answer. So my questions are; 1. How many Stars are their in our Galaxy? 2. How many Galaxies are their in our Local Group? 3. How many Galaxy Clusters are their in our Local Supercluster? 4. How many Superclusters have we found so far? 5. How many starts in total are their in all of the Superclusters?
Okay so I chose to take a year to decide which career to study, I've always been interested in physics and astronomy but I think I will go on and pick Chemistry. Any tips or ideas on what to do after?
Hi my name is Jay, new to all and any forums, lol. Not sure where to start so here I go. I have a few questions about Sirius the double star while observing through my Nexstar 4se telescope using a 2x Barlow and my neximage burst color. While I was able to capture quite stunning results of the star Sirius, this morning before sunrise, I was curious though as to if I might have incorrectly focused my scope on the star or if this image is a clear image of the star? I will attach a brief 7-8 second video I took this morning. It was the first time I had gotten to focus my scope on the star as it kept drifting before but I solved the drifting issue as a result of improper anti-backlash. But now back to the video, was wondering if any of you could help determine if I properly focused on the star because from what I see the star appears to be in the shape of an out-of-control atom in the video and at the center it is black, is this the observing of a quasar? Thanks for all the help in advance if anyone stops by thanks for the time and efforts here's the video. star.avi
