3/29/16: Earth-space telescope system produces hot surprise
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.…

03/26/2016: Reflections: Looking for peace and quiet? Go to West Virginia
I was sitting at my favorite corner table, enjoying a cup of coffee and a plate of bacon and eggs. While scanning the front page of the Record-Eagle, I noticed a man sitting alone at a table facing me. He was looking my way and talking but I couldn’t make out what he was saying.…

03/25/2016: For Some, Einstein’s Space-Time Ripples Have Yet To Break Their Silence
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…

03/23/2016: AT&T uses low-power antennas to prevent cellular interference with telescope
AT&T engineered an unusual low-power antenna system inside a radio quiet zone at a snow resort in rural West Virginia, giving thousands of daily smartphone users network access for the first time. Work on the multimillion-dollar solution started in 2013 and took months of testing with engineers at the National Radio Astronomy Observatory (NRAO) and…

03/11/2016: Berthoud students discover space anomaly
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,…

03/09/2016: All We Are is Dust in the Interstellar Wind
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…

02/25/2016: Mysterious radio burst pinpointed in distant galaxy
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…

02/24/2016: Pulsar web could detect gravitational waves
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…
