Latest Cosmic distance ladder Stories
Observations from the NASA/ESA Hubble Space Telescope, collected over the span of five weeks, show the variable star RS Puppis growing alternately brighter and dimmer – a phenomenon known as a light echo.
A 12-year study of massive stars has reaffirmed that our Galaxy has four spiral arms, following years of debate sparked by images taken by NASA's Spitzer Space Telescope that only showed two arms.
The ALHAMBRA project has identified and classified more than half a million galaxies, after seven years of close observation of the universe
Using data from the recently conducted survey of the early universe performed by NASA’s Hubble Space Telescope, an international team led by American astronomers has identified the most distant and earliest galaxy ever detected.
A team of Texas and California scientists have discovered the most distant galaxy to date, after searching through a database of nearly 100,000 galaxies imaged by the Hubble Space Telescope as part of the CANDELS survey.
PGC 6240 is an elliptical galaxy that resembles a pale rose in the sky, with hazy shells of stars encircling a very bright center.
A team of NASA scientists have found an 'ultra-compact dwarf galaxy' that may be the densest galaxy ever discovered.
Researchers at the Max Planck Institute have now created the most detailed 3D model of the inner structure of the Milky Way ever.
Scientists have proposed a groundbreaking new theory to explain the discrepancies between different methods for measuring the expansion of the universe.
A supermassive black hole is believed to sit at the center of each large galaxy and a new technique designed to detect the dark abyss's spin could be the key to unraveling a galaxy's history.
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...
