Giant elliptical galaxies are not as likely as previously thought to be cradles of technological civilizations such as our own.
Astronomers have detected molecular oxygen in another galaxy over half a billion light-years away for the first time outside the Milky Way.
Researchers have simulated the formation of galaxies in a universe without dark matter for the first time.
Astronomers obtained the most detailed anatomy chart of a monster galaxy located 12.4 billion light-years away. Using the Atacama Large Millimeter/submillimeter Array (ALMA), the team revealed that the molecular clouds in the galaxy are highly unstable, which leads to runaway star formation. Monster galaxies are thought to be the ancestors of the huge elliptical galaxies […]
TEHRAN – While looking for an unusual star in the nearby Andromeda galaxy, astronomers instead found a pair of supermassive black holes. The binary system is the most closely orbiting pair of black holes of their kind we have ever seen. In a statement Thursday, NASA ascribed the finding to the black holes photobombing images […]
Dark matter and dark energy may not actually exist, according to a study which suggests that accelerating expansion of the universe and the movement of the stars in the galaxies can be explained without these concepts. For close to a century, researchers have hypothesized that the universe contains more matter than can be directly observed, […]
