    Center Galaxy
AI Thread Summary
The center of the galaxy is located along the ecliptic in Sagittarius, which raises questions about whether this alignment is coincidental. Some argue that it is merely a coincidence, as the position changes over time due to the sun's orbit around the galaxy, which takes approximately 250 million years. This alignment is temporary, with the center shifting about 90 degrees over a 100 million-year period. The current alignment is not perfectly aligned, being off by 5-6 degrees from the expected position. Overall, the discussion suggests that the center's location along the ecliptic is not a significant or permanent feature.

Is there a reason the center of the galaxy is along the elipitic (in Sagitarius)? Or is that just a coincidence.

To the best of my knowledge I would say that it is merely coincidence.
 
And it's only temporary, it happens twice in each orbit of the sun around the galaxy (250Myr?) so in a 100Myr it will be 90deg away.

It's also not a very good coincidence, it's 5-6deg off out of a possible 90.
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

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...
