Centauri Dreams 16 Oct 2018, 17:08 UTC It was back in 2012 that Eric Mamajek (University of Rochester) and team discovered a possible ring system around the star J1407 in lightcurves originally taken in 2007, spawning subsequent work with Leiden Observatory’s Matthew Kenworthy. And what a ring system it would be if confirmed. The diameter, based on the lightcurve, would be nearly 120 million kilometers. This would be a ring system nearly 200 times larger than the rings of Saturn, one containing an Earth’s mass of dust particles, and in early studies, one housing over thirty separate rings.
The Planetary Society Blog 16 Oct 2018, 11:00 UTC When I was scrolling through the downlinked images of Hayabusa2’s approach of asteroid Ryugu, a familiar sight caught my attention (and the attention of those who share in my niche appreciation for scattering and optical effects). It wasn’t the spacecraft’s shadow resembling a Canadian flag (though I think we appreciated that as well), but rather, a brilliant heiligenschein.
All About Space 16 Oct 2018, 09:15 UTC Researchers have identified a young star with four Jupiter and Saturn-sized planets in orbit around it, the first time that so many massive planets have been detected in such a young system.
Planetaria 15 Oct 2018, 22:24 UTC On October 4, 2018, the initial construction of one of the latest additions to the exoplanet-hunting family was announced – the European Space Agency’s Plato mission. The announcement was made at the 69th International Astronautical Congress in Bremen, Germany, where the new contract was signed.
Discover 14 Oct 2018, 04:41 UTC I’ll admit, I was skeptical about the director of La La Land telling the story of Neil Armstrong’s historic landing on the Moon. (Would there be songs? A scowling J.K. Simmons?) It turns out to be a synergistic pairing of artist and material. First Man brushes aside the expected saga of space cowboys saddling up their steel horses, delivering instead a moving narrative of NASA’s glory days as seen through Armstrong’s eyes.
SpaceFlight Insider 14 Oct 2018, 01:10 UTC Roscosmos has announced the initial results of its investigation into the Soyuz MS-10 launch failure. According to the agency, the emergency abort was caused by a collision of elements during the separation of Soyuz-FG rocket’s first stage.
SpaceFlight Insider 12 Oct 2018, 19:30 UTC NASA’s Chandra X-ray Observatory entered into safe mode, according to a statement from the U.S. space agency. This comes about a week after another telescope—Hubble—entered into safe mode because of a gyroscope issue.
