What happens when galaxies collide: Hubble showcases six mergers

To celebrate a new year, the NASA/ESA Space Telescope has published a montage of six beautiful galaxy mergers. Each of these merging systems was studied as part of the recent HiPEEC survey to investigate the rate of new star formation within such systems. These interactions are a key aspect of galaxy evolution and are among the most spectacular events in the lifetime of a galaxy.

It is during rare merging events that galaxies undergo dramatic changes in their appearance and in their stellar content. These systems are excellent laboratories to trace the formation of star clusters under extreme physical conditions. The Milky Way typically forms star clusters with masses that are 10 thousand times the mass of our Sun. This doesn’t compare to the masses ...

Indian-Origin Scientist Solves 10-year-old Mystery Over Fast Radio Busts From Universe

An Indian-origin scientist and his team from Cornell University found the origin of mysterious busts of radio waves from the cosmological source to more than 3 billion light-years away. The “fast radio bursts”, which puzzled space scientists for over ten years, were previously thought to have had emanated from within the Milky Way galaxy, but the astronomers now confirm that ...

Oxygen Found in Distant Galaxy

University of California (UCLA) astronomers have made the first accurate measurement of the abundance of oxygen in a distant galaxy called COSMOS-1908. “This is by far the most distant galaxy for which the oxygen abundance has actually been measured,” said Alice Shapley, a UCLA professor and co-author of the study. “We’re looking back in time at this galaxy as it ...

Japan Researchers Find Signs of 2nd Largest Black Hole 200 Light Years Away

Japanese researchers have found a mysterious second largest black hole in the Milky Way, which could be possible missing link in black hole evolution. Tomoharu Oka and his team of astronomers from Keio University in Japan found the enigmatic gas cloud, called CO-0.40-0.22, about 200 light years away from the center of the Milky Way. The CO-0.40-0.22 is unusual with a ...

Scientists Use ISS Pictures to Map Light Pollution

Researchers belonging to the Cities at Night project have obtained nighttime images of cities from the International Space Station (ISS) in order to gauge the light pollution globally. The new study that was released on Tuesday at IAU XXIX General Assembly in Hawaii, established that the diffuse glow that is witnessed from space is nothing, but dispersed light from streetlights ...

NASA’s Spitzer Telescope Finds Distant Planet, Using Microlensing Technique

NASA’s spitzer telescope has found a gas planet as far away as 13,000 light years away, the distant celestial body known in the category, called ‘Ogle-2014-BLG-0124Lb’. The gas giant planet is thought to be half the mass of Jupiter. Underlining the spitzer telescope discovery, scientists said Spitzer can be used further to see how planets are distributed throughout the spiral-shaped Milky ...

Nitrogen, Water Traces on Mars Show Life Was Possible in Ancient Red Planet

The nitrogen sample analysis of Curiosity findings could have made it possible for life organism to survive on Mars. Since the nitrogen found on Mars doesn’t show any evidence of life as the surface of Mars is inhospitable for living organism, the researchers believe that the nitrates found on Mars are ancient, and could have come from non-biological processes like meteorite impacts ...

Dark matter at the heart of our galaxy?

New study confirms the presence of dark matter in the inner part of the Milky Way. Scientists have obtained for the first time a direct observational proof of the presence of dark matter in the innermost part the Milky Way, including at the Earth’s location and in our own ‘cosmic neighborhood’. In a first step they created the most complete ...

The Role of Thread-Like Filaments in Evolution of Galaxy

An international team of researchers discovered that thread-like "filaments" in the cosmic web play an important role in the evolution of galaxies like our Milky Way. The cosmic web is a large-scale web-like structure comprising galaxies and the filaments are like bridges connecting the denser regions in the cosmic web. "We think the cosmic web, dominated by dark matter, formed ...
