The Samsung Galaxy S III Mini

Samsung has announced its latest handset at a press event in Frankfurt, Germany. The four-inch Galaxy S III Mini is an Android-powered smartphone designed to provide a premium alternative to the company's larger Galaxy S III device.  Read More

Astronomers have found evidence that the Milky Way is embedded in an enormous halo of hot ...

An international team of astronomers has combined data from NASA's Chandra X-ray observatory, ESA's XMM-Newton space observatory and Japan's Suzaku satellite to suggest that our galaxy may be surrounded by a halo of hot gas extending in all directions for hundreds of thousands of light-years. The finding also offers clues as to why more than half of the ordinary matter in early galaxies has seemingly disappeared without leaving a trace.  Read More

Zoomed-in image of barred spiral galaxy NGC 1365, around 60 million light years from Earth...

The Dark Energy Camera (DEC) has captured an initial batch of images as part of an ongoing quest to afford scientists with a better understanding of dark energy. The images were taken by the 570-megapixel behemoth from its location within the Chilean Andes on September 12 while undergoing a series of tests. Scientists hope it may soon help answer one of the biggest mysteries in physics: why the expansion of the universe is speeding up.  Read More

A new approach for simulating the birth and evolution of galaxies and cosmic filaments within the Universe has been developed by researchers at the Harvard-Smithsonian Center for Astrophysics together with their colleagues at the Heidelberg Institute for Theoretical Studies. It's called AREPO, and has been used to simulate the evolution of our Universe from only 380,000 years after the Big Bang to the present. The full variety of spiral, elliptical, peculiar, and dwarf galaxies appear in the simulated Universe.  Read More

When astronomers used the Hubble Space Telescope to scout a remote patch of the sky and investigate the early stages of galaxy formation, they stumbled upon something which they did not expect. They realized that the distant spiral galaxy BX422, appearing to us as it was only three billion years after the Big Bang, seems to be uncharacteristically well-formed for its young age. By studying its features, which are in direct contrast with our current knowledge of galaxy formation, scientists hope to shed more light on how spiral galaxies – including our own – are formed.  Read More

3.75 billion years from now - the nighttime sky showing the Andromeda galaxy (M31) early i...

When Galaxies Collide! It sounds like an early science fiction novel. However, analysis of Hubble measurements shows that our own Milky Way galaxy is moving toward a head-on collision with our nearest neighbor, the Andromeda galaxy (also known as M31). The collision will start in about four billion years, and over the following three billion years the two spiral galaxies will coalesce into a large elliptical galaxy. Based on this data, NASA has produced a video of the upcoming collision.  Read More

Over the course of a year, NASA's Interstellar Boundary Explorer (IBEX) scans the entire sky. During February, its instruments are aligned in the correct direction to intercept atoms that have crossed the boundary from interstellar space into our solar system, become caught by the Sun's gravity and slung around the star. This has now allowed IBEX to capture the most complete glimpse of the material that travels in the galactic wind in the space between star systems. The results indicate this material doesn't look like the same material that makes up our solar system.  Read More

Pushing the NASA/ESA Hubble Space Telescope to the very limit of its technical ability, an international collaboration of astronomers believe they have discovered the oldest and furthest ancient galaxy ever seen. Light from the new object is thought to have taken some 13.2 billion years to reach the telescope, with the age of the Universe itself said to be 13.7 billion years. It's also said to be older than the current record holder, which set the bar by forming 600 million years after the Big Bang.  Read More

The verse “Twinkle, twinkle little star, how I wonder what you are” could, in fact, refer to the frustration felt by astronomers trying to view celestial objects obscured by turbulence in the earth’s atmosphere. It’s that turbulence that causes stars and other heavenly bodies to twinkle, and it’s one of the reasons that space-based telescopes like the Hubble can see those objects more clearly than telescopes down here on the ground. Recently, however, a team of astronomers from the University of Arizona developed a technique that allows them to effectively turn off the twinkling over a large field of view, allowing them to get Hubble-quality images in a fraction of the usual time.  Read More

Move over Google Maps, NASA's Interstellar Boundary Explorer (IBEX) spacecraft has given scientists the tools to construct the first comprehensive sky map of our solar system and where it resides in the Milky Way galaxy. NASA says the new view will change the way researchers study the interaction between our galaxy and sun.  Read More
