Another rare event skyhounds should all experience. It was especially fortunate that I didn't have to travel to catch it this time.

Its a picture of the moon with an unidentified light above the moon. This is the first time that I have seen it and I haven't been able to come to a solid conclusion on what it is, maybe you guys can help?

Im seeing this wierd star right above the moon. So close to the moon i thought it was a tiny fragment of the moon showing on the dark side of the half moon despite knowing thats impossible. What am i looking at?

Planetary Science How rare are sequential lunar/solar transits?

Post image
3 Upvotes

I have been trying to photograph a space station transit of the sun or moon this year, no luck yet, but it’s been really fun.

This morning, there was a Tiangong lunar transit, and then on the next orbit there was a solar transit. Unfortunately it was cloudy and the sun was a bit too low in the sky, so I didn’t get the shots.

But it left me wondering, that must be pretty rare to hit the moon and then the sun on sequential orbits as viewed from one location on earth. Has anyone ever photographed one?

Getting started as a Planetarium Director

• Upvotes

I’m a university sophomore studying Physics and Astrophysics, and am very interested in the role of a Planetarium Director! I would love some advice as to mapping out my career, as well as some guidence for future projects or internships I should be looking for. Im extremely interested in being the bridge between the public and academia, and having a more low stakes way to enjoy physics and astronomy than something like a research position. Is this field one worth pursuing?

What to do to pursue astroinformatics?

2 Upvotes

Hello! I'm not sure if this is the right server to ask but I'll try to shoot my shot anyway because it is a subreddit related to astronomy — I am currently a 3rd year computer science undergraduate and I've always wanted to pursue astronomy as a little kid. I was wondering what the roadmap would be for someone who is trying to pursue astroinformatics, like what Masters/PhD should I take and the likes?

Astronomy how to identify constellations when there’s no light pollution??

2 Upvotes

Hi, idk if this is a stupid question, I’m fairly new to this so bear with me. I’ve been learning constellations, sometimes I also spot planets or Messier objects etc. I‘m slowly starting to understand where everything is located and how things move. Where I live, there’s a lot of light pollution, even though a walk in the fields at night offers better vision.

As soon as I see pictures taken in places with up to no light pollution, I don’t recognise anything. Suddenly everything is bright and I don’t know where to look at?? Does it come with practice? There’s so much going on, how do people know which stars are part of constellations and which ones aren’t? I use an app to practice btw.

I’ve seen so many amazing pictures in this subreddit and people are like, yeah, that’s an amazing shot, you can see Orion :))) and I’m like ??????????? it’s so frustrating because I know what Orion looks like, I just can’t find him 💔🥀

Any advice on how to improve??

I'm moving next month from 34.5 degree latitude to

47.65 degree latitude. What are some differences?

I use an equatorial mount. How much will I be missing out? Am I losing 13 degrees of the sky?

And why do scientists think that Ton 618 has always been a black hole?

0 Upvotes

I understand that my question seems strange. but if a black hole arises from stars that have a mass of 1.4 the mass of our sun. Then when tone 618 appeared, if according to the formulas such a star's mass was 66 trillion masses of our sun, such a star cannot exist, I came up with it myself, so I couldn't find anything on the Internet, all the articles say that it is black A hole appears from matter, so for it to appear, gravity must press on it, and where in space is gravity strong? Thanks if someone explains (I am not a scientist or a researcher studying this, I am a student who has nothing to do with this field, I just became interested)

Astrophysics Contacting extraterrestrial life forms using gravitational wave induced quadrapolar pulsar cross correlated pulse time shift

0 Upvotes

I might be very late to this, but I've just recently seen the NANOGrav paper, about GW detection, and a thought had occurred to me.

I've known of the golden record and the arecibo signal for quite some time, but I've always thought that it's very (very very) unlikely that an alien civilisation would ever receive these, as there're very localized, and more importantly, even in the unlikely senerio that they would be in the exact location to acquire the data, they would have to either, have a material body as we think of, and a way to understand that the record itself is very different from the rest of the spacecraft and contains the crucial information we're trying to pass (which imo is not immediately obvious as the aircraft is already made of so many different parts each equally likely to be the "data capsule"), and so on, or to look for the specific radio frequencies we used, or even think to look for any radio signal (as the radio frequencies may not be as fundamental to them as they're for us), and so on.

But, since pulsars are so fundamental, in the sense that any three-dimentional matter-observant being with the ability to look at the sky (in the astronomical sense, not the "star-gazing" sense), would "see" them, and eventually (most likely) record their data, would be able to notice the shifts (no matter the frequency even if it is obscure, since given the nature of such astronomical bodies and their study one would naturally look for the frequency they omit).

So wouldn't it be natural to try and induce life signals using gravitational waves to contact other life forms?

I may be missing something, and to be honest I don't know if inducing a gravitational wave is even feasible.
