AI Thread Summary
Bar-centered galaxies, including types SBa, SBb, and SBc, exhibit unique structural features that raise questions about their origins. The forces influencing these galaxies remain a mystery, prompting inquiries into their velocity, density, and spectral distributions. Detailed stellar spectra from these galaxies could provide insights into their formation and mass calculations. The discussion highlights the evolving nature of galactic evolution as a field of study. Understanding these forces is crucial for advancing knowledge in astrophysics.

Some of galalxies have bar style center.
Very mysterious.
The origin?
The galaxies are SBa, SBb and SBc style.
Spiral galaxies are familiar to us. it seems like hurricane.
What kinds of force act on bar centered galaxies?
 
Astronomy news on Phys.org
Are there any data about the velocity distribution from the center to the edgy, or the density distribution in the Universe, or the spectrum distribution about those galaxies?
The detail stars spectrum of one of that kind of galaxies would be very useful to know the origin, I think. And calculated galaxy mass.
 

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...
