Discovering Anomalies: Extra-Galactic Meteor Observed by Russian Scientists"

AI Thread Summary
Russian scientists observed a faint meteor on July 28, 2006, using a 6 meter telescope, leading to the discovery of several anomalies in its spectrum. The meteor's high velocity raised questions about its potential extra-galactic origin, although this remains unconfirmed. Some participants in the discussion express skepticism, noting that the conclusion relies heavily on velocity and spectral analysis, which could also indicate common meteorite composition. The possibility of extragalactic meteors is acknowledged, given the abundance of space debris. Overall, the findings prompt further investigation into the nature and origins of such meteors.

Somehow, I find news items such as this one much more interesting to read than those about maps of dark-matter halos and things of that nature. (Not that I'm uninterested in the latter.)

On July 28, 2006, Victor Afanasiev from the Russian Academy of Sciences was making observations using a 6 meter telescope equipped with a multi-slit spectrometer. By chance, he observed the spectrum of a faint meteor as it burned up in the Earth’s atmosphere, and in looking at the data, found several anomalies.

Is it something you want to discuss / ask ?
 
Just posting a news item (I thought this was a bit serious for GD. :biggrin:), although a discussion would be good. It's not confirmed to be an extra-galactic meteor, and hence the '?'.
 
Might have just been moving 80kps with respect to the center of the galaxy.

I don't see why it isn't possible for an extragalactic meteor to hit us, with tons of debris floating around up there. Pretty cool stuff imo.
 
I am skeptical. The article largely bases the extra-galactic conclusion on the high velocity, but then they go on to analyze 246 meteors in 36 hours and claim 12 may have been extra-galactic based on velocity alone. That seems very improbable.

Then they bolster the extra-galactic conclusion on the spectra showing the composition of iron, magnesium, and oxygen; but that is what is found in meteorites routinely.
 

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 '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.
