ASTRONOMERS IN A SPIN­DLE

Sky at Night Magazine - - BULLETIN -

A sur­vey has shown that ul­tra-rare spin­dle gal­ax­ies might ac­tu­ally be rel­a­tively com­mon. While ex­am­in­ing the struc­ture of 600 gal­ax­ies, the team from the Max Planck In­sti­tute for As­tron­omy found eight new spin­dles – prop­erly known as ‘pro­late ro­ta­tors’ be­cause these cigar-shaped gal­ax­ies ro­tate along their long axes. The strange gal­ax­ies are thought to form when two large disc gal­ax­ies col­lide and merge at right an­gles to cre­ate long, thin gal­ax­ies.
