Observations from NASA’s Juno spacecraft reveal that Jupiter’s strong magnetic field and the unique properties of its plasma ...

The Hubble Space Telescope captured an image of NGC 4694, a galaxy that possesses unusual properties that complicate its classification.

Cosmic Guitar Elliptical galaxy NGC 3561B (upper left) and spiral galaxy NGC 3561A (lower right) form a shimmering guitar shape in the ongoing merger known collectively as Arp 105.

About 72 percent of the galaxies we’ve studied are spiral, like ours, but there are two other types of galaxies out there that we’ve observed. Elliptical galaxies are, well, elliptical in shape.

Seen from Earth, the giant elliptical galaxy M87 is just a two-dimensional blob, though one that appears perfectly symmetrical and thus a favored target of amateur astronomers.

The image has been released as part of celebrations to commemorate Hubble's 35th anniversary this year.

Astronomers have detected fast-repeating radio bursts from a distant "dead" galaxy that should not contain the energy to produce these types of signals.

Hot Jupiters are some of the most extreme planets in the galaxy. These scorching worlds are as massive as Jupiter, and they swing wildly close to their star, whirling around in a few days compared ...

The majority of the thousands of galaxies we’ve discovered out in the universe fit into relatively well-defined categories: spiral galaxies like our Milky Way, elliptical galaxies which are long ...

What happens when you build the largest digital camera on Earth, capable of capturing 3.2 gigapixel images, and aim it at the depths of space from a remote Chilean mountaintop? You get results like ...

The telescope also picks up Jupiter’s faint rings, which are only one-millionth the brightness of Jupiter itself, against a backdrop of even fainter and farther galaxies.
