Latest Cosmic distance ladder Stories
Astronomers discovered light echoing off of material surrounding a recent supernova explosion, supporting the theory that exploding white dwarfs become unstable from matter donated by large non-degenerate stars.
Astronomers using NASA's Hubble Space Telescope have mapped out a 3D structure of material ejected from an exploding star.
New research using the ultra-sharp radio vision of the National Science Foundation's Very Long Baseline Array (VLBA) has determined that we live in a more upscale neighborhood in our galaxy than previously thought.
Scientists have finally resolved the mystery over the distance and measured brightness of a nearby star system known as SS Cygni.
Astronomers say they have discovered a star factory in a galaxy so distant that they see it when the Universe was only six percent of its current age of about 13.7 billion years old.
The NASA/ESA Hubble Space Telescope has broken the record in the quest to find the furthest supernova of the type used to measure cosmic distances.
Astronomers discovered a new type of supernova of a star about 10 to 100 times more massive than our sun.
The ink is drying on a brand new birth certificate for a star that's been around for a very long time. New calculations using NASA'S Hubble Space Telescope have enabled a group of astronomers to take an important step closer to reconciling the age of this star, and the age of the Universe.
Astronomers have now accurately measured the distance to our neighboring galaxy, the Large Magellanic Cloud after using observations of eclipsing binaries.
The Coma Cluster (Abell 1656), along with the Leo Cluster, is one of two major clusters compromising the Coma Supercluster. It contains over 1000 identified galaxies. Most of the galaxies in the center of the Coma Cluster are elliptical galaxies including both dwarf and giant. However the center is dominated by NGC 4874 and NGC 4889, two giant elliptical galaxies. The brightest galaxies are visible, a few degrees north of the galactic pole, with an amateur telescope larger than 20 cm. The...
