But in 1950, astronomer Arther Hoag discovered a galaxy unlike any other: Hoag's object, dominated by a vast, ring-like halo. 70 years later, we're still struggling to piece together this galactic ...

Hoag’s Object, a galaxy 600 million light-years away, has a familiar yellow core and a normal outer region of young blue stars, but the rest of it is missing.

Hoag’s Object: A Nearly Perfect Ring Galaxy Image Credit: NASA, ESA, Hubble; Processing: Benoit Blanco. NASA and the European Space Agency have shared this beautiful and striking image of a most ...

Today, Hoag’s Object is one of the finest, most perfect examples of a rare galaxy type: a ring galaxy. It’s over 600 million light-years away in the constellation Serpens and spans over ...

Then in 1987, a team led by Schweizer suggested that Hoag’s object formed when a lightweight galaxy passed by a heavier, elliptical one whose gravity tore the lighter traveller apart.

Ring galaxies, also known as Hoag-objects, are exceptionally rare in the universe—less than 0.1 percent of all observed galaxies are Hoag-type galaxies—and astronomers make a big fuss whenever ...

Hoag's Object is around 120,000 light years wide, which is slightly larger than our Milky Way Galaxy. It also sits around 600million light years away from the Serpens constellation.
