Photographer Alex Cherney has dedicated his life’s work to capturing the night sky.

A star-gazer with just an ordinary digital camera has come a little bit closer to the final frontier.   – Alex Cherney spent 18 months photographing the night sky and turned thousands of snaps into incredible time-lapse video of the cosmos. (Pics)

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.

This is an artist’s impression of the source HLX-1

A group of international astronomers in the UK, France and the USA, led by the University of Leicester, have found proof to confirm the distance and brightness of the most extreme ultra-luminous X-ray source, which may herald a new type of Black Hole.

This artist’s conception illustrates one of the most primitive supermassive black holes known (central black dot) at the core of a young, star-rich galaxy.

Astronomers have come across what appear to be two of the earliest and most primitive supermassive black holes known. The discovery, based largely on observations from NASA’s Spitzer Space Telescope, will provide a better understanding of the roots of our universe, and how the very first black holes, galaxies and stars all came to be.

WISE Captures a Cosmic Rosebud Blossoming With New Stars

100316183430-large

A new infrared image from NASA’s Wide-field Infrared Survey Explorer, or WISE, shows a cosmic rosebud blossoming with new stars.

A new infrared image from NASA’s Wide-field Infrared Survey Explorer, or WISE, shows a cosmic rosebud blossoming with new stars. The stars, called the Berkeley 59 cluster, are the blue dots to the right of the image center. They are ripening out of the dust cloud from which they formed, and at just a few million years old, are young on stellar time scales.

Cosmic Tapestry: Giant Filaments of Cold Dust Stretch Through Milky Way

100317101340-large

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.
