Arp 4 is a galactic duo immortalized by the Hubble Space Telescope. In the image, a small bright spiral appears to be orbiting around a larger, darker companion. However, this apparent proximity ...

This new image from the NASA/ESA Hubble Space Telescope is one of the best ever views of Arp 4, a visual pair of galaxies in the constellation of Cetus. Arp 4 consists of the small, bright spiral ...

Peering through cloud cover can be quite a challenge, although spacecraft help, as shown by a stunning Hubble image, one from NASA's Mars Odyssey orbiter, and one from Magellan showing volcanoes on ...

Why it's so special: What if a galaxy had only one spiral arm? Our solar system resides on the outskirts of one of the Milky Way galaxy's estimated four spiral arms, according to Space.com, but not ...

The spiral galaxy NGC 3596 is on display in this NASA/ESA Hubble Space Telescope Picture of the Week, which incorporates six different wavelengths of light. ESA/Hubble & NASA, D. Thilker You might ...

ABSTRACT: A simple gravitational alternative to the Hubble-Lemaitre Law is presented. Measured redshifts are attributed to gravitation rather than recessional velocity. The measured redshift-distance ...

Halton Arp was an American astronomer. He was known for his 1966 Atlas of Peculiar Galaxies, which (it was later theorized) catalogues many examples of interacting and merging galaxies, though Arp ...

Also known as Arp 104 in Halton Arp’s Atlas of Peculiar Galaxies, this target is the pairing of an elliptical NGC 5216 and barred spiral galaxy NGC 5218. Both were discovered by William Herschel in ...

When astronomer Fritz Zwicky discovered ESO 350–40 (now called the Cartwheel Galaxy) in 1941, he considered it one of the most complicated known galaxy structures, based on its stellar dynamics.

It was a prime year for gazers of the greater Cosmos. NASA’s James Webb Space Telescope (JWST) saw its first full year of operation in 2023, and the venerable Hubble Space Telescope is still trucking, ...
