Welcome to the first episode of our 19th season! This week we
look at objects coming from other solar systems that come passing
on by our Sun. During the summer hiatus the 3rd interstellar
object was discovered: Comet 3I/ATLAS! So now we have 3 different
interstellar interlopers to compare & contrast. What are we
starting to learn about other star systems from this small sample
size and how will our detection get even better?

[Editor’s note: HiRISE’s telescope is 1/2 meter.]
