Collision or merger of two galaxies, mostly one large galaxy and several small ones is common in the Universe. Astronomers have also observed some major mergers among the pair of galaxy similar in size. But, US team of astronomers observed one of...

The satellite data as observed by XMM-Newton and NASA’s Chandra X-ray had led Renato Dupke and his colleagues from the University of Michigan witness the merger of two galaxies at speed of more than 2,000 miles per second. This collective...

Universe as I always say is a cloud of mysteries and not many of these have yet been answered by astronomers. To answer these questions one has to go back in time. No, I am not talking about a time machine, as the best way to go back in time is to...

Researchers involved with AEGIS have carefully selected 544 distant galaxies to learn how galaxies take their mature forms. Galaxies are born small and eventually grow when they start taking a mature form. The galaxies that are examined weigh...

NASA’s Hubble Space Telescope has shot an image of a diverse cluster of galaxies called the Abell S0740. The cluster shows images that are around 450 million light-years from earth and in constellation Centaurus. At the center of the...

Astronomers at the SRON Netherlands Institute for Space Research have made observations with the ESA’s XMM-Newton X-Ray observatory and have concluded that our Universe is 1.5 times richer in than previously expected. Our body elements that...

We all know that the visible part of the universe that is the stars, gases, planets and galaxies account for only one-sixth of the universe. The rest part of the universe is unseen. The rest of the universe is all dark matter that does not emit or...

No doubt, Hubble still dominates with its presence in the outer space but Mars rovers and ISS have also thrilled us with images out of this world. With all these space shuttles and satellites orbiting the extremes of our solar system staring at the...

One of the most commonly asked questions our scientists receive is about the existence of life elsewhere in our universe. But answering a straight forward YES or NO, scientist community prefer to say if there is water or atmosphere or in other...

One of the great scientific instruments of all time, which has given the clearest pictures of galaxies forming in the very early universe, is looking straight into the eyes of the scientists for help. Its fate will be decided after the announcement...

One of the great scientific instruments of all time, which has given the clearest pictures of galaxies forming in the very early universe, is at the mercy of the scientists for its survival. After 16 years and thousands of hours observing the universe,...

The new Hubble images are no doubt telling us a great deal, about how the Galaxies might have behaved in their initial stages. The new image is the best demonstration of how large massive galaxies are built by merging the smaller ones. However, what...

There is a huge intergalactic shock wave, or "sonic boom" in the middle of Stephan's Quintet, a group of galaxies which is now the scene of a gigantic cosmic cataclysm. This is revealed by recent infrared observations made with NASA's Spitzer Space...

How are the massive galaxies in our universe formed? A study by an academic at The University of Nottingham gives us the first observational evidence for this. The implications of this study are vast. And to explain seemingly unrelated processes such as...

To be successful in an oblivion venture all that is needed is not only painstaking calculations and a really big telescope – but, bolstered optimism. Then how can one measure something he can't see or feel!? That is what a researcher at Cambridge...
