Over the next decade, the Green Bank Observatory in Pocahontas County will see a $20 million investment as part of a search for extraterrestrial intelligence.
The 10-year, $100 million project called Project Breakthrough Listen was announced last year, the Gazette-Mail’s Rick Steelhammer reported. Scientists have been using the Green Bank Telescope since January to search the 200 stars nearest Earth for radio signals bearing clues to the possible presence of other civilizations.
The project is funded by Russian billionaire Yuri Milner, and famed cosmologist Stephen Hawking is also involved.
Researchers will use other telescopes and instruments across the globe. According to Steelhammer’s article: “Project Breakthrough Listen will make use of about 20 percent of the Green Bank Telescope’s observation time during the next 10 years, bringing a total of $20 million to the Green Bank Observatory. In addition to the 100-meter Green Bank Telescope — the world’s largest fully steerable telescope, Breakthrough Listen also makes use of the Parkes Radio Telescope, in Australia, and the Automated Planet Finder, at the Lick Observatory near San Jose.”

Most mornings, Steve Padilla rides in an open-air elevator to the top of the 150-Foot Solar Tower at Mount Wilson Observatory, in the mountains just east of Los Angeles. When he opens the dome, sunlight beams in. Padilla aligns two mirrors in the century-old telescope, sending a reflection of the Sun toward a lens. Downstairs, a 17-inch image of the star appears on a piece of paper
Padilla catches a ride back down in the elevator and stands before the paper. It’s time to draw.
All day, Padilla will sketch sunspots, adding his drawings to an archive that stretches back to 1917—the longest consistent record of solar activity. This has been his routine for 40 years. “In a way,” he says, “you could say these drawings are a little daily work of art.”
And so, on top of this mountain, he sits like wise man of old, a knower of stars, a person apart. And also a volunteer. In recent years, Mount Wilson Observatory’s funding—and particularly the money for the 150-Foot Solar Tower—has waned. Padilla stayed after the money left, in April 2014, because this telescope, and this mountain, are his life. “I had so many years here, I didn’t know what to do if this is all over now,” he says.

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 circled by a pair of stars. Standing on the surface of the KELT-4Ab, the two orbiting stars would appear as bright as the full moon does in our sky.In addition to describing an exotic solar system, the study also provides new details on the evolution of a “hot Jupiter,” or a gas giant that orbits close to its host star.
KELT-4Ab, which is approximately the same size as Jupiter, orbits KELT-A once every three days. The nearby stars KELT-B and KELT-C orbit each other once every three decades, and jointly they travel around KELT-A and its planet about every 4,000 years.

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, gotten a look at fine structure in the radio-emitting regions of quasar 3C273, which was the first quasar known and is still one of the brightest quasars known. The result has been startling, violating a theoretical upper temperature limit. Yuri Kovalev of the Lebedev Physical Institute in Moscow, Russia, commented:
We measure the effective temperature of the quasar core to be hotter than 10 trillion degrees!
This result is very challenging to explain with our current understanding of how relativistic jets of quasars radiate.

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. Their achievement produced a pair of scientific surprises that promise to advance the understanding of quasars, supermassive black holes at the cores of galaxies.
The scientists combined the Russian RadioAstron satellite with the ground-based telescopes to produce a virtual radio telescope more than 100,000 miles across. They pointed this system at a quasar called 3C 273, more than 2 billion light-years from Earth. Quasars like 3C 273 propel huge jets of material outward at speeds nearly that of light. These powerful jets emit radio waves.
