Less than 0.1% of all observed galaxies are Hoag-type galaxies, and the researchers are stumped by how the rings of the galaxy were formed.
The world's largest digital survey of the visible Universe, mapping billions of stars and galaxies, has been publicly released.
A recently discovered galaxy is undergoing an extraordinary boom of stellar construction, revealed by a group of astronomers led by University of Florida graduate student Jingzhe Ma using NASA's Chandra X-Ray Observatory.
This delicate blue group of stars — actually an irregular galaxy named IC 3583 — sits some 30 million light-years away in the constellation of Virgo (The Virgin).
This elliptical galaxy is a beautiful cosmic oddity, with a bright core wrapped in system of dark, swirling, thread-like filaments.
Astronomers have found an extremely faint dwarf satellite galaxy of the Milky Way.
Space energy anomalies more than 50 million light years from our galaxy are creating conditions that should be destroying stars, but instead are regenerating them.
The results have clear implications for galaxy formation, and also helps shed light on an ancient astronomical paradox - why is the sky dark at night?
