The spiral galaxy NGC 2008 sits center stage, its ghostly spiral arms spreading out toward us, in this image captured by the NASA/ESA Hubble Space Telescope.

New theory of evolution for spiral galaxy arms

(PhysOrg.com) -- A study of spiral patterns found in galaxies like our Milky Way could overturn the theory of how the spiral arm features form and evolve. The results are being presented by postgraduate student, Robert Grand, ...

Image: Hubble peers at peculiar pair of galaxies

This striking image from the NASA/ESA Hubble Space Telescope showcases Arp 298, a stunning pair of interacting galaxies. Arp 298—which comprises the two galaxies NGC 7469 and IC 5283—lies roughly 200 million light-years ...

Mapping our galaxy's magnetic field

Astronomers from CSIRO and Curtin University have used pulsars to probe the Milky Way's magnetic field. Working with colleagues in Europe, Canada, and South Africa, they have published the most precise catalogue of measurements ...

A spiral galaxy with a secret

(Phys.org)—The NASA/ESA Hubble Space Telescope – with a little help from an amateur astronomer – has produced one of the best views yet of nearby spiral galaxy Messier 106. Located a little over 20 million light-years ...

Believe it or not, this long, luminous streak, speckled with bright blisters and pockets of material, is a spiral galaxy like our Milky Way. But how could that be? 

Image: Hubble sees elegant spiral hiding a hungry monster

NGC 4639 is a beautiful example of a type of galaxy known as a barred spiral. It lies over 70 million light-years away in the constellation of Virgo and is one of about 1,500 galaxies that make up the Virgo Cluster.
