05/23/2016: Science: Nurturing Success From Failure
On a calm November evening in 1988, the 300 foot radio telescope at Green Bank Observatory collapsed. While the collapse was a huge blow to radio astronomy, it is somewhat surprising that it lasted as long as it did. The radio telescope was proposed in 1960 as a way to fill the observational gap between…

05/10/2016: Virtual Earth-space telescope sheds new light on Milky Way
Astronomers have created a virtual Earth-space radio telescope more than 100,000 miles across – a super-high resolution that reveals new details of a quasar and our Milky Way. The researchers were surprised when their Earth-space system revealed a temperature hotter then 10 trillion degrees. “Only this space-Earth system could reveal this temperature, and now we…

04/21/2016: Hunt Continues for Gravitational Waves from Black Hole Megamergers
The sound of merging supermassive black holes does not saturate the universe. For the past decade, scientists with the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) collaboration have been listening for a constant “hum” of low-frequency gravitational waves. Theoretical work suggests that this hum — generated by collisions involving supermassive black holes, which contain…

04/20/2016: The Town without Wifi
You can’t make a call or send a text on your cell phone in Green Bank, West Virginia. Wireless Internet is outlawed, as is Bluetooth. As you approach the tiny town on a two-lane road that snakes through the Allegheny Mountains, the bars on your cell phone fall like dominoes, and the scan function on…

04/14/2016: The monstrous temperature of a black hole
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…

03/31/2016: Researchers discover incredibly rare triple star system
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…

03/30/2016: The extremely hot heart of quasar 3C273
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,…
