Sublime New Hubble Image Reveals a Thrilling Exchange Between Two Galaxies

Posted by in categories: materials, space

The ongoing interaction between two galaxies 320 million light-years away has been captured in a gorgeous Hubble image.

They’re collectively known as Arp 282 in Halton Arp’s Atlas of Peculiar Galaxies, and they consist of a large barred spiral galaxy named NGC 169, about 140,000 light-years across, and a much smaller polar-ring galaxy named IC 1,559, which is about 40,000 light-years across.

These two galaxies have drawn close enough together that they’re exchanging material. That’s not unusual: Although space is vast and mostly empty, galaxies are gravitationally drawn together, perhaps channeled along strands of the invisible cosmic web that stretches across and plays a vital role in shaping the Universe.
