The appearance of this object has interested amateur astronomers as much as its uncommon structure has fascinated professionals. Hoag’s Object is a ring galaxy in Serpens Caput. The above photo taken by the Hubble Space Telescope in July 2001 reveals unprecedented details of Hoag's Object and may yield a better understanding. - The gap separating the two stellar populations appears almost completely dark, but may contain some star clusters that are

Hoag's Object spans about 100,000 light years and lies about 600 million light years away toward the constellation of the Snake ( Serpens ). Between the …

Hoag's Object is a non-typical galaxy of the type known as a ring galaxy. A nearly perfect ring of young hot blue stars circles the older yellow nucleus of this ring galaxy. When it comes to singularities, black holes are only half the story. Is this one galaxy or two? Hα emission is detected along the entire ring, at least to the limit of the luminous stellar component. The presence of a blue detached ring, viewed face-on, around a red central core gives Hoag’s Object its unique appearance. Many galaxies far in the distance are visible toward the right, while coincidentally, visible in the gap at about seven o'clock, is another but more distant ring galaxy. He identified it as either a planetary nebula or an unusual galaxy. The object has about eight billion stars, and is ~600 million light-years away in the constellation Serpens.. Characteristics. Astronomer Art Hoag first asked this question when he chanced upon this unusual extragalactic object. The galaxy was discovered in 1950, by Art Hoag (Hoag (1950)).He described its appearance as … This galaxy, like Hoag's object, has an elliptical-like core with a nearly perfect outer ring, where the outer ring has a population of younger, bluer stars than the inner core. It was named after the American astronomer Arthur Allen Hoag, who discovered it in 1950. White holes — regions of space where nothing can enter — are returning to the experimental spotlight. Hoag's object is a ring galaxy.The galaxy is named after Arthur Allen Hoag who discovered it in 1950. On the outside is a ring dominated by bright blue stars, while near the center lies a ball of much redder stars that are likely much older. Hoag's object fun facts Size - So-called “classic” ring galaxies are generally formed by the collision of a small galaxy with a larger disk-shaped galaxy. The galaxy has an apparent magnitude of 16.0 and is approximately 600 million light years distant from the solar system. We present new H I observations of Hoag's Object (HO) obtained with the Westerbork Synthesis Radio Telescope. Hoag’s Object. Hoag’s Object, with a background ring galaxy. The data show that the luminous optical ring around the elliptical body has a bright H I counterpart that shares the kinematical properties of the optical ring.
