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,…

The astronomers’ achievement produced a pair of scientific surprises that promise to advance the understanding of quasars, supermassive black holes at the cores of galaxies. Astronomers using an orbiting radio telescope in conjunction with four ground-based radio telescopes have achieved the highest resolution, or ability to discern fine detail, of any astronomical observation ever made.…

When leaders of the Laser Interferometer Gravitational-wave Observatory, or LIGO, announced in February the first-ever direct detection of a gravitational wave, astrophysicists Scott Ransom from the National Radio Astronomy Observatory and Andrea Lommen at Franklin and Marshall University in Lancaster, Pennsylvania, had mixed feelings. On the one hand, it meant that the team they and…

Collin Miller describes the slate of speakers at the Society of Amateur Radio Astronomers Western Regional Conference in Arizona this weekend: “There’s doctor this, and doctor someone, PhDs, then you have Berthoud High School STEM students.” Miller and fellow high school senior, Xander Pickard, will present the research of a team of six Berthoud students,…

Cosmic dust is not simply something to sweep under the rug and forget about. Instead, National Science Foundation (NSF)-funded astronomers are studying and even mapping it to learn more about what it might be hiding from us, where it comes from, and what it’s turning into. Some researchers are delving deep down to see how…

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…

Researchers are studying the best way to use pulsars to detect signals from low-frequency gravitational waves, like those from colliding supermassive black holes. The recent detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) came from two black holes, each about 30 times the mass of our sun, merging into one. Gravitational waves…

T The Milky Way enjoys a light drizzle throughout its galactic year. These cosmic raindrops are speedy clouds of mostly hydrogen gas that rain down onto our galaxy’s spiral disk. They fly through space at hundreds of kilometers per second (millions of miles per hour) and don’t rotate with the Milky Way. They’re appropriately named…
