AI Thread Summary
Stars can indeed have highly eccentric orbits around the center of their galaxy, similar to the orbits of comets in the solar system. There are numerous examples of such stars, including those with orbits that are not aligned with the galactic plane. These eccentric orbits can result from gravitational interactions, such as with black holes. The discussion highlights the existence of black hole candidates that exhibit these unique orbital characteristics. Overall, the phenomenon of stars with eccentric orbits is well-documented and supported by various astronomical studies.

An interesting question has arised from one of the discussions around here: are there any stars that have a highly eccentric elliptical (or even parabolic/hyperbolic) orbit around the center of their gallaxy, somewhat like comets have in our solar system? And for that matter, are there any stars whose orbits are not aligned with the gallactic plane?

Yes, plenty. Some examples (click on the links in each website below to get more info):

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
