Explore the warped spiral galaxy NGC 3718 and its neighbor NGC 3729 — a dynamic duo of deep-sky oddities in the constellation Ursa Major.

Argentinian astronomers have employed the upgraded Giant Metrewave Radio Telescope (uGMRT) to perform high-resolution radio ...

Messier 77, captured by Hubble, also known as the Squid Galaxy, is a swirling spiral 45 million light-years away in Cetus, the constellation named for a whale. It was discovered in 1780 by Pierre ...

A massive 673-foot observation tower has been proposed for a site in Denver’s Central Business District.

DENVER — A newly proposed 673-foot observation tower could become one of the tallest structures in Denver — if it ever gets built.

A spiraling 673-foot observation tower could soon twist its way into Denver's skyline — if the city gives it the green light. Why it matters: The structure would be unlike anything else in Denver or ...

If built, the proposed tower would soar to a height that would make it the fourth-tallest structure in the city and state.

Scientists have long assumed the Oort Cloud, one of the most mysterious structures in our solar system, to be spherical.

A team of scientists accidentally visualized a hidden spiral in the Oort Cloud, and it might change everything we know about the solar system.

An accidental discovery in an astronomy show offers researchers a new clue about the mysterious Oort Cloud, a large expanse of icy bodies revolving around the sun.

The spiral structure, visible here behind the sun in a scene from the show, surprised scientists and animators when they saw it projected on the planetarium's dome during preproduction.

Astronomers have observed a galaxy dating to an earlier epoch in the universe's history that surprisingly is shaped much like our Milky Way - a spiral structure with a straight bar of stars and ...
