“The dwarf galaxy NGC1052-DF2”

Paul Pudaite points to this post by Stacy McGaugh entitled, “The dwarf galaxy NGC1052-DF2.” Pudaite writes that it’s an interesting comment on consequences of excluding one outlier.

I can’t really follow what’s going on here but I thought I’d share it for the benefit of all the astronomers out there.

P.S. Apparently it is common for giant galaxies to have some dwarf satellite galaxies. Who knew?

    Not just giant galaxies – the Milky Way has 50-odd:

    Most of them are extremely faint though

    I find remarkable the use of a subscript emoji to indicate solar mass.
