The Ursa Minor Dwarf is a small galaxy, a loose aggregation of stars, and a satellite of the Milky Way. Its gravitational center lies 200,000 light-years away, and it seems to have undergone a ...

We present a Bayesian method to identify multiple (chemodynamic) stellar populations in dwarf spheroidal galaxies (dSphs) using velocity, metallicity, and positional stellar data without the ...

The galaxy LEDA 1313424 has been nicknamed the Bullseye Galaxy, thanks to the nine rings that circle its bright center. ... Deep-Sky Dreams: The Ursa Minor Dwarf Galaxy. Cosmology, Galaxies.

The Milky Way may merge with the Large Magellanic Cloud in 2 billion years, not Andromeda, contrary to previous findings.

Every major galaxy like the Milky Way has a retinue of smaller dwarf galaxies orbiting it. The Milky Way has several dozen, including the famous Large and Small Magellanic clouds. Beginning in the ...

Webb takes a closer look at Abell S1063, a distant galaxy cluster that acts like a cosmic lens, peering into the universe’s past. ... The Ursa Minor Dwarf Galaxy. Cosmology, Galaxies.

Like magnificent large spiral galaxies, small galaxies also form stars. In the image, the dwarf irregular galaxy "Ugc 2858" shows bright blue young star clusters and pink areas where stars are ...

The current North Star can be found easily by locating the Big Dipper asterism in Ursa Minor, which is high overhead this time of year. Draw an imaginary line from the magnitude 2.3 star Merak, ...

Certainly, every galaxy is capable of producing an enormous number — roughly a handful every century — of small black holes with masses of up to 100 or so times that of the sun.

Their study, published in Nature, poses new challenges to the prevailing galaxy formation models within the Λ-Cold Dark Matter (ΛCDM) framework. advertisement Phys.org ...

A collision between the Milky Way and neighboring galaxy Andromeda is far from a sure thing; in fact, it could hinge on the flip of a cosmic coin.
