Quasars, the brightest objects in the cosmos, could act as cosmic signposts, directing astronomers to elusive pairs of supermassive black holes. New research suggests that quasars — the luminous ...

Plenty of groups have been theorizing about primordial black holes (PBHs) recently. That is in part because of their candidacy as a potential source of dark matter. But, if they existed, they also had ...

Two upcoming episodes of the History Channel’s popular series The Universe will feature Pittsford resident and Rochester Institute of Technology professor Don Figer. A crew from the History Channel ...

Quasars, the luminous beacons at the centers of distant galaxies, have puzzled astronomers for decades with their dramatic brightness variations. Recent observations suggest that these celestial ...

Space might seem calm when gazing up at the night sky, but invisible waves ripple continuously through the universe, bending space and time. These waves, known as gravitational waves, carry crucial ...

The new study suggests that miniture solar systems would not necessarily look like our own. This composite of planets in our solar system was taken by various NASA spacecraft. Included in the image ...

How are stars born and how do they die? -- How do we know that black holes exist? -- Who is the strangest in the cosmic zoo? -- How far is it to the stars and will we ever be able to travel to them? - ...

Astronomy is a never-ending wonder: planets and stars, comets, black holes, supernovas, quasars, pulsars and much more. And above all, the miracle of life. This exciting travel questions the place of ...

A little bit of “scruff” in scientific data 50 years ago led to the discovery of pulsars — rapidly spinning dense stellar corpses that appear to pulse at Earth. Astronomer Jocelyn Bell made the chance ...

Introduction: the natural history of the heavens and the natural history of discovery -- Part I. Entrée: 1. The Pluto affair -- Part II. Narratives of Discovery: 2. Moons, rings, and asteroids: ...

"Targeted searches will be up to seven times more likely to find gravitational waves from a supermassive black hole binary in a quasar than in a random massive galaxy." When you purchase through links ...
