"We found that some comets in the inner Oort cloud form a long-lasting spiral structure." Spirals are a repeating theme in astronomy, with arguably the most famous example of a swirling armed structure being our home galaxy,

Astronauts aboard the International Space Station (ISS) have a front-row seat to some of the most extraordinary sights in the cosmos, but few images manage to capture the vastness of space quite like the latest masterpiece from Don Pettit.

The shot of our planet and the great cosmos beyond offers an eerie sense of scale to our quotidian situations on Earth.

NASA astronaut Don Pettit captures a breathtaking image of the Milky Way from the International Space Station, offering a rare view of our galaxy from orbit, amidst ongoing scientific research and experimentation.

Using NASA's James Webb Space Telescope, Northwestern astrophysicists gained the longest, most detailed glimpse yet of the supermassive black hole at the center of the Milky Way.

New research may shine a light on part of outer space's great mysteries: the Oort Cloud. The Oort Cloud is the name given to a theorized group of potentially trillions of icy objects on the edge of our solar system.

Astronomers have spotted displays of flashing lights and “fireworks” near a supermassive black hole at the center of the Milky Way galaxy, a finding researchers said could reveal details about how black holes—among the most mysterious objects in space—behave and interact with their environment.

NASA’s SPHEREx mission will survey the entire sky in 102 different “colors” of light, offering scientists an unprecedented look at the earliest days of the universe and much more

The inner Oort cloud, between 1,000 and 10,000 AU from the sun, displays a spiral formation with arms that extend 15,000 AU.
