AI Thread Summary
A newly discovered galaxy, comparable in mass to the Milky Way, emits only 1% of its light, primarily due to its lack of star formation. The discussion highlights that this galaxy may have lost its gas before forming stars or had its gas dispersed due to rapid spinning. The term "dark twin" is debated, as the galaxies are not exact copies but rather complementary in nature. Participants express curiosity about future discoveries from studying this galaxy. The naming of the galaxy raises questions about its romanticized title, suggesting alternatives could be more engaging.

A galaxy as massive as the Milky Way emits only 1% as much light.

Interesting article, thanks. I expected a connection with dark matter, however it appears to me they are saying something along the lines of the stars never ignited unlike in typical formation areas. Am I getting it wrong?
 
The galaxy is mostly dark matter. But for some reason, it never made many stars--maybe because it lost its gas before it could, or maybe because it was spinning so fast its gas was too spread out to do so.

Cool, thanks. It will be interesting to see what discoveries come from studying the area.
 
Why dark twin? It isn't even an exact copy- they just compliment each other. Why not romanticize the discovery and call it the mysterious mate or dark lover or at least something else more exciting?
 

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.
