June 3, 2015 1:00 PM Here's How Our Night Sky Would Look If Celestial Bodies Were Closer To Earth

From breathtaking nebulae to spectacular galaxies, the cosmos is chock-full of stunning celestial objects. But think how stunning those objects might look if they were much closer to Earth -- close enough for us to see them in the night sky without having to use a telescope? "Beautiful video... Just perfect," YouTube user Alexander Ivanov commented 61

May 20, 2015 9:45 AM Happy Birthday Hubble: 25 years of super shots from outer space

25 years ago today, NASA's Hubble Space Telescope sent back its first photo of outer space. Since then, Hubble has provided us with some of the most detailed images ever of our solar system, our galaxy, and our universe, allowing a deep view into space and time. From bizarre nebulas and distant galaxies to supernovas and interstellar clouds, these photos 58

April 28, 2015 6:08 PM Astrophysicists build 3-D map of the universe

"It has peaks and valleys much like a mountain range," said lead researcher Mike Hudson. But researchers at the University of Waterloo have done just that, mapping the galaxy clusters, near and far, that make up the entirety of the cosmos. The spherical map features a comprehensive arrangement of galaxy superclusters, each galaxy and galactic cluster 79

April 27, 2015 6:43 AM Cosmic Tsunamis Have Capabilty to Resurrect Dead Galaxies

Recently astronomers have discovered that giant cosmic shockwaves emerged out of collision of galaxy clusters and that they are capable of starting an all new star generation. Galaxies often migle up ito groups that contain red and dead galaxies. Scientists say that these dead galaxies that have stopped forming new stars long ago can be brought back to life by giant 37

April 26, 2015 9:34 PM Cosmic Waves Breathe New Life to Dead Galaxies

Galaxies are regularly found in clusters, which contain what are called “red and dead” associates that quit making stars in the past. Presently new research has found that giant intergalactic waves can breathe new life into these dead galaxies. To clarify this occurrence, the global group of stargazers contrasts systems with that of urban communities 41

April 26, 2015 7:36 PM Galactic Collision Revives Dead Galaxies

When two galaxies have a galactic collision and travel into each other, a massive amount of energy is released. Scientists have discovered that this is can be so intense that it revives nearby dead and dormant galaxies. However, it was also discovered by the team of scientists at Leiden Observatory that this revival of the previously dead stars may only be temporary 49

April 26, 2015 6:35 PM Cosmic tsunamis can regenerate ‘dead’ galaxies

The shockwave formed by colliding galaxy clusters can initiate new star formation. Astronomers have recently discovered that giant cosmic shockwaves emanating from colliding galaxy clusters are capable of jumpstarting new star generation. According to a Nature World News report, galaxies are often clustered into groups containing “red and dead” galaxies 38

April 26, 2015 2:52 PM Cosmic Tsunamis Can Revive 'Dead Galaxies'; Revival Might Be Temporary: Researchers

Cosmic tsunamis or collisions between numerous galactic clusters releases immense amount of energy which can revive "dead galaxies." The revival may be temporary in some cases. Cosmic tsunamis or collisions between numerous galactic clusters releases immense amount of energy which can revive "dead galaxies." The revival may be temporary in some cases 42

April 26, 2015 12:35 PM Cosmic tsunami can revive ‘dead’ galaxies: researchers say

Intense energy released by collisions between galactic clusters can revive 'dead' or 'sleeping' galaxies, though only temporarily, an international team of researchers said. A galaxy is pronounced dead when it has expanded to its full capacity over a very lengthy period of time, and stopped creating new stars. Many starts of such a galaxy have also used their 39
