4/1/16: He Drew the Sun for 40 Years, but now his Telescope is Dying
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…

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,…

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.…

03/25/2016: 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…

03/11/2016: 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…
