Is it possible to mount a telescope on a plane? Is it beneficial?
I was wondering if any planes had mounted telescopes with the intent to observe the stars. I understand that the atmosphere itself can warp and hinder incoming light and even completely obscure views ...

What caused this mysterious stellar occultation on July 10, 2017 from something ~100 km away from 486958 Arrokoth?
In 2017 a series of stellar occultations by asteroid 2014 MU69 "Ultima Thule" now officially named 486958 Arrokoth were timed in order to obtain better orbital information before the New ...

How do we know that objects that appear in duplicate or triplicate, etc. due to strong gravitational lensing aren't actually multiple objects?
If we are looking at faraway objects, there is no parallax view, correct?
So isn't there a chance that an object that appears multiple due to strong foreground gravitational lensing is actually ...

Could stellar occultations be used to survey Kuiper belt objects?
The first hint we had as to the shape of Ultima Thule was via an occultation study using an array of small telescopes. Has anyone investigated the feasibility and effectiveness of conducting a survey ...

Is 486958 Arrokoth (2014 MU69 aka Ultima Thule) the only solar-system object determined to be binary by occultation?
The asteroid 486958 Arrokoth was discovered to be binary by astronomers lugging a bunch of telescopes around (I think) camping with them. The timing offered additional astrometry for the orbit ...

What is the farthest reported distance from observer from which a solar system body has occulted a star?
I originally wrote "...farthest distance from Earth..." but changed to "observer" in case the occultation was observed from a space telescope. It may not matter much but I didn't want to over-...

Automated (and hopefully free) systems I can subscribe to sending email or SMS text message when the T Coronae Borealis Nova becomes visible?
My earlier question about predicted potentially observable events Has a gravitational microlensing event ever been predicted? If so, has it been observed? is limited to microlensing.
Now I have just ...

For detection of distant galaxies by gravitational lensing-induced magnification, roughly what are the distance ratios from the lensing systems?
Discussion in comments under the question Does seeing a gravitationally lensed/magnified galaxy imply that they could also see us as well? have got me wondering about the geometry behind detection of ...
