Amazing
I have a hard time following all the technical information so I took off a star, but that’s unfair to Fraser Cain. Just saying, this is a challenge to an intelligent but novice student of astronomy.

Talking Points

Recent interactions between the hosts and their guests.

[Interview+] Phobos Might Already Be Destroyed and Reformed. Possibly Multiple Times

Q: What was the key takeaway from the DART momentum transfer experiment?

The experiment showed that the momentum imparted to the target was greater than the direct momentum of the impactor because ejecta escaping in the opposite direction provided an additional thrust, effectively increasing the net deflection capability.

[Q&A+] Eliminating Night Darkness, Voyagers' Lifetime, JWST's Planets

Q: MLBrilliance, when do you think we will be able to see the Great Attractor unobstructed, and what do you suppose we'll hope to find?

We have already seen the Great Attractor fairly unobstructed with current infrared observations, and the ongoing work aims to map galaxies beyond the Milky Way's dust to better understand the mass distribution and the large-scale structure, with expectations grounded in improving data and methodologies rather than a singular breakthrough.

[Q&A+] Eliminating Night Darkness, Voyagers' Lifetime, JWST's Planets

Q: Giga Sigma, thoughts on putting a reflector in orbit to eliminate darkness at night.

The idea is theoretically possible but would require a gigantic, expensive reflector and would have limited, incremental benefits; there are also downsides like ecological disruption and an increase in Earth's net energy budget, so without a compelling reason, most scientists and policymakers would likely reject it.

[Interview+] What Would It Take to Catch Up With a Meteorite?

Q: What's next for your research?

They're exploring improvements to the LSST linking algorithm, including streak-based matching to reduce false positives and to enable faster, more reliable trajectory assessments.

[Interview+] What Would It Take to Catch Up With a Meteorite?

Q: Can you give a sense of what kind of volume is going through this?

About 800,000 alerts per night are being generated, most of which are not imminent impactors, but the system is designed to surface useful candidates for follow-up.
