Astronomers have unveiled the nature of hundreds of gamma-ray emitting sources, discovering that most of them belong to the class of active galaxies known as blazars. Their recent study was published in The Astronomical Journal. One of the most intriguing

Astronomers have discovered unusual signals coming from the direction of the Milky Way’s center. The radio waves fit no currently understood pattern of variable radio source and could suggest a new class of stellar object. “The strangest property

“Mini supernova” explosion. Credit: NASA. Using the world’s most powerful radio antenna, scientists have discovered stars unexpectedly blasting out radio waves, possibly indicating the existence of hidden planets. The University of Queensland’s Dr Benjamin Pope and colleagues at the Dutch national observatory ASTRON have been searching for planets using the

Asteroid Bennu. Credit: NASA/Goddard/University of Arizona. Scientists thought asteroid Bennu’s surface would be like a sandy beach, abundant in fine sand and pebbles, which would have been perfect for collecting samples. Past telescope observations from Earth’s orbit had suggested the presence of ¬¬large swaths of fine-grain material called fine regolith
