From January & February 2024.


Today's 2 topics:


- My Catalina Sky Survey teammate Greg Leonard was asteroid
hunting in the constellation of Aquarius with our Schmidt
telescope on Mt. Bigelow, Arizona when he discovered his 19th
comet. Turns out Greg's new comet is a member of a family of
comets orbiting the Sun like a string of cosmic pearls across the
vast distances in our solar system.


- In the past two decades astronomers have discovered that
galaxies are not randomly distributed in space but rather occur
along filaments of mass with huge empty voids between them. How
objects and structures in the early Universe became nearby
clusters of galaxies and third generation stars like our Sun is
an evolving picture we are beginning to understand.
