The Galaxy’s Sugary Center Could Change How Life Began

This episode covers three very different astronomy stories and then
moves into a lively Q&A with listener questions. Andrew Dunkley
and Professor Fred Watson discuss a possible sugary molecule in the
center of the Milky Way, the risk lunar landers may contaminate ice
that could preserve clues to life’s origins, and a new way to track
lost dogs using satellite connectivity. The second half of the
episode answers questions about moons with atmospheres, secret
astronomy, hot Jupiters, and black hole mergers.
Key topics
In this episode, Fred Watson explains an update from Peter Verweyen
on MOND, now referred to as Aether Scalar Tensor Theory, and how it
relates to dark matter and dark energy debates.
We discuss the detection of erythrulose, a sugar molecule found in
interstellar gas clouds near the center of the Milky Way, and why
this matters for prebiotic chemistry.
Fred describes how molecules like sugar can form in cold molecular
clouds before stars and planets exist, making some ingredients for
life surprisingly common.
We discuss a new study warning that rocket exhaust from future
lunar landings could contaminate ice in permanently shadowed
craters at the Moon’s south pole.
The Moon’s polar ice may contain ancient prebiotic molecules
delivered by comets, asteroids, and dust, making it a possible time
capsule for the chemistry that led to life.
We discuss the practical and ethical problem that landers have to
use rocket engines, and those exhaust plumes may spread methane and
other organics across the lunar surface very quickly.
Fred shares how satellite-based direct-to-cell or direct-to-mobile
systems could help locate lost dogs in remote places without cell
coverage.
We discuss how this kind of tracking builds on existing GPS pet
trackers, and how it could be useful in wilderness areas, while
also noting the limits and concerns in national parks.
