Launched in 2013, the Gaia satellite has been scanning the sky to measure the positions, distances and motions of more than one billion stars in…
The formation of the Sun, the Solar System and the subsequent emergence of life on Earth may be a consequence of a collision between our…
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found quasi-periodic flickers in millimeter-waves from the center of the Milky Way, Sagittarius (Sgr) A*. The team…
Just like we orbit the sun and the moon orbits us, the Milky Way has satellite galaxies with their own satellites. Drawing from data on…
Astronomers have pondered for years why our galaxy, the Milky Way, is warped. Data from ESA’s star-mapping satellite Gaia suggest the distortion might be caused…
An abundance of mysterious gamma radiation exists in the center of the Milky Way, called the Galactic Center GeV Excess. Previous research determined that this…
Is there dark matter at the center of the Milky Way? A new analysis puts dark matter back in the game as a possible source…
Star-quake vibrations lead to new estimate for Milky Way age. Data gathered by NASA’s now defunct Kepler telescope provides a solution to an astronomical mystery….
A radio telescope in the Western Australian outback has captured a spectacular new view of the center of the galaxy in which we live, the…
International team detected radio bubbles with South Africa’s MeerKAT telescope. A gigantic, balloon-like structure has been hiding in plain sight, right in the center of…
Our Milky Way is a thrifty galaxy. Supernovae and powerful stellar winds eject gas from the galactic disk; nonetheless, this gas returns to the galaxy…
Researchers find evidence of a cataclysmic flare that punched so far out of the galaxy its impact was felt 200,000 light years away. A titanic,…
This infrared image from NASA’s Spitzer Space Telescope shows a cloud of gas and dust full of bubbles, which are inflated by wind and radiation…
An international team of astronomers has discovered one of the largest features ever observed in the center of the Milky Way – a pair of…
New research led by astrophysicists at Durham University, UK, predicts that the Large Magellanic Cloud (LMC) could hit the Milky Way in two billion years’…
ESA’s Gaia mission has made a major breakthrough in unraveling the formation history of the Milky Way. Instead of forming alone, our Galaxy merged with…
