Latest Cosmic distance ladder Stories
The European Space Agency’s (ESA) billion-star surveyor mission is slowly beginning to see more clearly. The Gaia spacecraft took a test image of a dense star of clusters in the Large Magellanic Cloud to help fine tune its instruments.
OAKLAND, Calif., Jan. 30, 2014 /PRNewswire-USNewswire/ -- Chabot Astronomers are tracking the latest supernova about 12 million light years away.
Several NASA spacecraft and Earth-based observatories, including the Hubble Space Telescope and the Chandra X-ray Observatory, are studying an incredibly close supernova that took place on January 21, officials from the US space agency announced on Friday.
According to Hubble’s law, the frequency of light from distant galaxies is shifted toward the red in a way proportional to their distance D, z = HD, where H is Hubble's constant. Dr. J.
Two of the brightest and most distant supernovae ever recorded have been discovered by astronomers affiliated with the Supernova Legacy Survey (SNLS).
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.
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...
