Red dwarf stars make up 80% of the stars in the universe.

Red dwarf stars are far more common than astronomers have believed — in fact, they may make up 80 percent of the star population, scientists said in a study on Wednesday that triples the number of stars in the universe.

Enigma of Missing Stars in Local Group of Galaxies

‘Missing’ stars in the Andromeda Nebula and our Milky Way?

In the local group of galaxies that also includes the Andromeda Nebula and our Milky Way, there are about 100 billion stars. According to astronomers’ calculations, there should be many more. Now, physicists from the University of Bonn and the University of St. Andrews in Scotland may have found an explanation for this discrepancy.

Cosmic Curiosity Reveals Ghostly Glow of Dead Quasar

A “Ghostly” image for those undead terrestrials

While sorting through hundreds of galaxy images as part of the Galaxy Zoo citizen science project two years ago, Dutch schoolteacher and volunteer astronomer Hanny van Arkel stumbled upon a strange-looking object that baffled professional astronomers. Two years later, a team led by Yale University researchers has discovered that the unique object represents a snapshot in time that reveals surprising clues about the life cycle of black holes.

The image spans about 50° of the sky. It is a three-colour combination constructed from Planck’s two highest frequency channels.

Giant filaments of cold dust stretching through our Galaxy are revealed in a new image from ESA’s Planck satellite. Analysing these structures could help to determine the forces that shape our Galaxy and trigger star formation.

Super Supernova: White Dwarf Star System Exceeds Mass Limit

Cosmologists use Type Ia supernovae, like the one visible in the lower left corner of this galaxy, to explore the past and future expansion of the universe and the nature of dark energy.

An international team led by Yale University has, for the first time, measured the mass of a type of supernova thought to belong to a unique subclass and confirmed that it surpasses what was believed to be an upper mass limit. Their findings, which appear online and will be published in an upcoming issue of the Astrophysical Journal, could affect the way cosmologists measure the expansion of the universe.
