Others in the atlas are dwarf galaxies in flux ... and Scutum-Centaurus arms — and two less obvious arms, the Sagittarius and ...

In the planetarium, data from the GAIA spacecraft shows the little Sagittarius Dwarf Galaxy dropping stars like breadcrumbs ...

Abstract: We present two simple dynamical models for Sagittarius based on N-body simulations of the progressive disruption of a satellite galaxy orbiting for 12.5 Gyr within a realistic Galactic ...

Abstract: We present radial surface brightness profiles for all five globular clusters in the Fornax dwarf spheroidal galaxy, and for the four present members of the Sagittarius dwarf spheroidal ...

The majority of the globular clusters associated with the Sagittarius dwarf galaxy are faint. In this respect it differs significantly from the globular cluster systems surrounding typical giant ...

The Full or Flower Moon is on May 12. The Moon is Last Quarter, rising at midnight, on May 20. On the 22nd, the waning ...

Structures known as "zippers" and "twisters" in the early universe may explain why dwarf galaxies tend to line up with each ...

The Ursa Minor Dwarf is a small galaxy, a loose aggregation of stars, and a satellite of the Milky Way. Its gravitational ...

Hubble’s image of the Large Magellanic Cloud reveals a cotton candy-like cloudscape using light our eyes can’t see, like ultraviolet and infrared. The result is both beautiful and informative. NASA ...

The Integral Sign Galaxy (UGC 3697) glows dimly and shows a warped, twisted structure indicative of past interactions.
