Latest Cosmic distance ladder Stories
A pair of French scientists has been able to recreate how the Milky Way’s spiral arms looked millions of years ago.
White dwarf supernovae that occurred millions of years ago have popped up in the Virgo Cluster galaxy and part of the sky labelled as "anonymous."
A Rutgers University astronomer has created computer models and simulations that help to explain how galaxies formed and evolved.
Astronomers have reportedly discovered the largest known structure in the universe – a formation so massive it would take a vehicle that was moving at light speed roughly four billion light years to cross it.
A massive star that astronomers have been watching mimic a supernova since 2009 has finally exploded for real.
Have you ever wished for a time machine to be able to travel to the distant past? What about a "Wayback Television Set" that would allow you to watch an entire month of ancient prehistory in real time?
Astronomers have discovered seven primitive galaxies that formed more than 13 billion years ago, during the Universe's infancy.
Astronomers have taken a census of hundreds of previously unseen starburst galaxies, revealing high star-formation rates across the Universe.
Astronomers use the distribution of clusters of galaxies to understand dark matter, and a research team has just used this tool to help understand the expansion history of our universe.
Two different groups of astronomers – one studying unusually dim supernovae, the other unusually bright ones – say both types can teach us a lot about the universe.
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...
