Answers to Common Questions
How do I Become an Astronomer/What do Astronomers Do?
What telescope/accessories should I buy?
What should I look for in the sky?
What Was That Bright Moving Object I Saw?
Where Can I Learn About Astronomy?
Can I Get Help With Homework?
Now before I explain my question. I am in no way a scientist. All that is proposed here as a question is just something that came to mind seeing a Youtube Short.
Now the Question
Is a Black Hole 4 dimentional?
The lady in the Short said the following. ' When you get in a black hole, you no longer go to a point in space. But you go to a point in time'. At least something in those lines was said.
Now that for me brings up the question. Because we as 3 dimentional beings only being able to move through space, while being guided by time. Could the Black hole be the 4 dimentional sphere we just cant observe in its entirety because it leaks into our 3 dimentional world?
Maybe my questioning is not the best, and if you want to know more about it please ask me. For now, what do you think about this?
Hello everyone! Here's a shot I took of the Pleiades star cluster from the dark skies of the French Alps.
This shot was taken using:
Nikon D5600 DSLR (stock)
Skywatcher Evostar 72ED Telescope
Skywatcher HEQ5 equatorial mount
ZWO ASI120MC-S Guide camera on a TS Optics 60mm guidescope
ZWO ASIAIR Mini to run everything
Processing was done using DSS, GIMP and Siril

I have my rig out with a telescope cover, but spider webs have formed in the tube despite my fruitless attempts to seal it shut. How could I clean it out? One of those febreeze dusters perhaps? Distilled water maybe?
Hello, I live in rural West Central Texas and at around 9 PM CST I saw a strange, idle(staying completely still) anomaly or strobe in the night sky. About every 6 seconds the light would fade in, then fade out with a slightly red aura/glow around them. I noticed that the lights formed a diamond/rhombus shape. I know it was not an illusion because I sat there for several minutes watching it and it was very visible. It was not some kind of structure or tower with those lights because obviously i would have seen it out my back porch in daylight. It was not an aeroplane, it was completely still. Is this some kind of satellite, but if so why was it in a rhombus shape? I do not have a video because it's so dark and not even my good quality phone camera can capture it.
ill post update when ill finish assembly!
Hello everyone !
I'm currently working on a science fantasy project that includes some worldbuilding. I'm trying to make the planet weird, alien and fantastical, but still grounded in real physics (to a point).
With that in mind, I've been trying to find unique astronomical phenomenon people on the planet could observe and form superstitions or religions around.
The first thing I came upon are twin stars, which, if I'm correct, could have habitable earth-like planets orbiting them without too much troubles.
Are there other fun things I could populate the night sky with while maintaining some realism ? Maybe celestial bodies whose orbit approaches the planet on a regular basis, making them visible and quite big but only at certain times of the year/decade/century ? Maybe a subsatellite on the moon ? Would that impact life as we know it ?
I hope the question is clear and not too broad, thanks for any help !
I'm looking for a data set that focuses on a relatively simple cause and effect relationship in astronomy that middle school student could analyze and draw conclusions from.
I dont mind researching and organizing the data, but i dont know where to start. Does anyone have a suggestion for an interesting relationship that can be graphed/understood by students?
I live deep in the city with a ton of light pollution. I often find it difficult to spot things at night, but very few things like Sirius, Jupiter. Saturn, Pleiades and beehive cluster are easy to spot. The v-band of my area is a bit more than 17.80 on a bortle 9 scale.
I use Stellarium to help identify potential points to look at when trying to use my skywatcher eq mnt, and I set my maximum magnitude in Stellarium to 4.75. Should this remain at this level, since I live in a light saturated area?
I stopped taking shots of Orion neb because of a hot Summer and waited all year since its just around the corner for Winter in northern hemisphere (late october). Should I set the magnitude a bit higher, or would it be a waste of time trying to look for something in the city that I will struggle to see?
I am using a DSLR with 300mm lens (budget) skywatcher mount and I also have an 8" dobsonian reflector for sight seeing the moon, which is irrelevant in this request.
Saw a recent post on another sub saying our sun “only” has 22 rotations left before it runs out of fuel and got me wondering how many rotations it’s already taken. Extra points if you can confirm that the “22 rotations left” is even a valid estimate. Thanks!
I keep hearing 2 different things. 1 is no and the other is yes but it's so faint it looks like a star. In ancient times there wasn't light pollution and with an orbit of 84 years, some lifelong astronomers might have noticed a difference.
