An impression of the encounter between the Milky Way galaxy and the smaller "Sausage" galaxy about 8 billion to 10 billion years ago. The record of this ancient encounter is still preserved in the velocities and chemistry of the stars. (V. Belokurov (Cambridge, UK); Based on image by ESO/Juan Carlos Muñoz)

Astronomers Discover Ancient Galactic Collision that Reshaped the Milky Way

July 6, 2018

A team of astronomers found evidence of a cataclysmic collision between the Milky Way and a dwarf galaxy some 8 to 10 billion years ago. The astronomers refer to this galactic crash as a ‘defining event’ in the early history of the Milky Way. They say the collision between our galaxy, and what is being […]

First Interstellar Visitor Probably Came From Binary Star System

March 21, 2018

Canadian astronomers think that the first confirmed interstellar object to enter our solar system, a rocky, cigar-shaped asteroid called ‘Oumuamua, probably came from a binary star system. To make their findings, the researchers at the University of Toronto’s Center for Planetary Science checked into just how effective twin star systems are at ejecting objects like […]

Black Hole Back Doors?; Io’s Atmosphere; No New Stars in Galaxy Center

August 5, 2016

Do Black Holes Have Back Doors? Most people describe a black hole as a cosmic object with gravity so strong that it sucks in any kind of material that comes close to it. What happens to stuff that is pulled into a black hole? Some scientists think that matter that enters a black hole gets […]

Astronomers Find a Bunch of ‘Monster Stars’ in Star Cluster

March 18, 2016

A group of astronomers probing a young star cluster within the ultraviolet section of the light spectrum just found a bunch of huge ‘monster stars.’ The R136 star cluster, located in the Tarantula Nebula, inside the Large Magellanic Cloud, is about 157,000 light years from Earth. They chose to explore in the ultraviolet range since there are […]
