With a perfectly symmetrical ring circling a red sphere of stars, Hoag's object is one of the prettiest mysteries in the universe.

Hoag's Object Is a Galaxy Within a Galaxy Within a Galaxy (and Nobody Knows Why)

By Brandon Specktor

Hoag's object, which is a galaxy within a galaxy within a galaxy, has befuddled stargazers since astronomer Arthur Hoag discovered it in 1950.

This illustration shows our solar system suspended in the "bubble" of protective solar wind known as the heliosphere. Where the sphere ends, harsh cosmic rays butt up against our solar system.

Top Space Stories of the Week!

These are the top space stories this week from Space.com.

Looming some 135 million light-years from Earth in the constellation of Centaurus is the bright emission line galaxy NGC 3749, seen here in an image from the Hubble Space Telescope. Astronomers can learn a lot about a galaxy by studying its spectrum of light, particularly the wavelengths of light that are emitted or absorbed by elements it contains. NGC 3749 displays strong emission lines, which means that it is "bursting with star formation and energetic stellar newborns," the European Space Agency said in a statement.

Two galaxies are caught in a crazy cosmic dance, pulling at each other in a fresh image from the Hubble Space Telescope.

In this new image from the Hubble Space Telescope, what looks like a top-down view of a jellyfish glowing in deep space is actually the planetary nebula NGC 2022. The cosmic orb of ionized gas was expelled from a dying red giant star located at its center. As the star sheds material into space, its core shrinks and grows hotter while emitting ultraviolet radiation that illuminates its gassy shell.

This new Hubble Space Telescope view of Jupiter, taken on June 27, 2019, reveals the giant planet's trademark Great Red Spot, and a more intense color palette in the clouds swirling in Jupiter's turbulent atmosphere than seen in previous years. Hubble's Wide Field Camera 3 observed Jupiter when the planet was 400 million miles (640 million kilometers) from Earth, when Jupiter was near "opposition," or almost directly opposite the sun in the sky.
