We explain what dark matter is in only 60 seconds.

In this PodcAstroholic we answer the question “How can spiral galaxies keep their shape?”

In this episode of the Astroholic LIVE, Dr Duncan Astle joined us to talk about the latest research into learning in children. We also talk about satellite galaxies made exclusively of dark matter, the three-body problem, the right-hand rule, tardigrades, and much more.
