Feel free to mention any special/cosmic phenomenon that surpises you the most

JWST has recently found massive well developed galaxies at high redshift (z>13). According to the linked study, these massive galaxies could represent an unexpected foreground contamination of the CMB, which might bring our interpretation of the CMB as a sort of "afterglow" of the big bang into question. It appears to at least suggest that the CMB strength may have been overestimated.

To clarify, I am not an astronomer or astrophysicist although I have studied physics at a graduate level (different subfield entirely however). I found this article and was curious if anyone knowledgeable had commented on it. It seemed strange to me how little attention this appeared to have gotten as it has significant potential to cause a ruckus in cosmology as far as I understand it. I found little commentary aside from a poorly written Newsweek article, so I thought I would try and raise awareness and discussion about this here as I was curious and had some free time on my hands.

If I missed some such discussion or post, let me know because I would like to hear the thoughts of other experts on this study.

Here is a new interesting interview with Fraser Cain. Fraser discusses his upbringing into science, proudest career moments, fine tuning, black holes, as well as his case for no aliens. He also gets into his favorite scifi media outlets. Fraser is a class act and was awesome to hear his insight and experience. Very humble and bright guy.

If you don't know Fraser Cain, he is a Canadian science communicator, best known as the founder and publisher of Universe Today. This is a website dedicated to space and astronomy news. He has a passion for making complex scientific concepts accessible to the public, and his work has helped thousands of people develop a deeper understanding of the universe. He is also the host of the Universe Today Podcast, where he discusses a wide range of topics related to space exploration, astrophysics, and astronomy with experts in the field. I believe he has been in this field since the late 90s.

Link to petition here

I’m not affiliated with the Planetary Society, but like most of you reading this, I care deeply about space exploration and I’m extremely troubled by the proposed budget cuts. The planetary society is leading the way and advocating our government to not make these cuts, and they have a petition which I realized is still short more than 2000 signatures of their goal that ends today.

Please sign the petition and write to your congress member! It takes just a couple minutes!

I just wrote an article for IEEE Spectrum (https://spectrum.ieee.org/planetary-defense-killer-asteroids) about my work on some big questions: Is humanity in danger from potentially deadly asteroid impacts? How can we spot them? And how can we protect ourselves?

I work at the Johns Hopkins Applied Physics Laboratory designing spacecraft that can crash themselves into asteroids to prevent them from hitting Earth.

I’ve researched asteroids for years. I was an Instrument Scientist for the Mercury Dual Imaging System (MDIS) and the Chair of the Geology Discipline Group for NASA’s MESSENGER mission. I have been on five field teams with the Antarctic Search for Meteorites (ANSMET) program. And asteroid 6899, Nancychabot, is named after me.

Read my article here: https://spectrum.ieee.org/planetary-defense-killer-asteroids

I am joined by Andy Rivkin, an expert in asteroids and planetary defense, to make sure we can address all your questions.

We will be here for two hours, from 1-3pm ET on June 12.
