Quasars are singular regions of the universe, very compact and very light surrounding a supermassive black hole. And this is precisely the black hole of 3C273 that attracted the attention of scientists, who have tried to determine its temperature. To do this, they have combined efforts of ground and space measuring instruments and thus requested […]

According to a newly-published study, a rare triple-star system containing a planet in a stable orbit was recently discovered by researchers at the Harvard-Smithsonian Center for Astrophysics. Published in the Astronomical Journal, the study detailed the discovery of distant world, known as KELT-4Ab. While the planet orbits one star in the system, that star is […]

Scientists combined telescopes on Earth and in space to learn that this famous quasar has a core temperature hotter than 10 trillion degrees! That’s much hotter than formerly thought possible. By combining signals recorded from radio antennas on Earth and in space – effectively creating a telescope of almost 8-Earth-diameters in size – scientists have, […]

For the first time, astronomers have traced an enigmatic blast of radio waves to its source. Since 2007, astronomers have detected curious bright blasts of radio waves from the cosmos, each lasting no more than a few milliseconds. Now scientists have been able to pinpoint the source of one of these pulses: a galaxy 1.9 […]
