Comet PanSTARRS (C/2017 S3) has erupted again! Now bright enough to see in binoculars, it might become a naked-eye object if it survives until perihelion.

Comet C/2017 S3 PanSTARRS Brightens
Michael: "The second outburst brightened the comet by 2m5 within three days. On the morning of July 17, it was already 8m0. A deep image showed a nearly 10 arc minute coma and a faint ion tail of more than half a degree. After the first outburst, the comet was weak from July 6 to 14."
"Everything is possible now."

Comet C/2017 S3 PanSTARRS: New Outburst
"C/2017 S3 PanSTARRS had a second outburst. After the first in early July, it could not maintain the brightness and became weaker again. But on July 15 the comet was 9 mag again and also showed an ion tail."

Comet C/2017 S3 (PanSTARRS) imaged by Michael Jaeger from Austria last night. The second outburst brightened the comet by 2m5 within three days. A deep image showed a nearly 10 arc minute coma.

This Day in Aviation History
July 27th, 1949
First flight of the De Havilland Comet.
The de Havilland DH 106 Comet was the first production commercial jetliner. Developed and manufactured by de Havilland at its Hatfield Aerodrome, Hertfordshire, United Kingdom headquarters, the Comet 1 prototype first flew on 27 July 1949. It featured an aerodynamically clean design with four de Havilland Ghost turbojet engines buried in the wings, a pressurised fuselage, and large square windows. For the era, it offered a relatively quiet, comfortable passenger cabin and showed signs of being a commercial success at its 1952 debut.
A year after entering commercial service the Comets began suffering problems, with three of them breaking up during mid-flight in well-publicised accidents. This was later found to be due to catastrophic metal fatigue in the airframes, not well understood at the time. The Comet was withdrawn from service and extensively tested to discover the cause; the first incident had been incorrectly blamed on adverse weather. Design flaws, including dangerous stresses at the corners of the square windows and installation methodology, were ultimately identified. As a result, the Comet was extensively redesigned with oval windows, structural reinforcement and other changes. Rival manufacturers meanwhile heeded the lessons learned from the Comet while developing their own aircraft.
Although sales never fully recovered, the improved Comet 2 and the prototype Comet 3 culminated in the redesigned Comet 4 series which debuted in 1958 and had a productive career of over 30 years. The Comet was adapted for a variety of military roles such as VIP, medical and passenger transport, as well as surveillance. The most extensive modification resulted in a specialised maritime patrol aircraft variant, the Hawker Siddeley Nimrod. Nimrod remained in service with the Royal Air Force (RAF) until June 2011, over 60 years after the Comet's first flight....

Dust and Cosmic Rays on Comet 67P
Previously unreleased imagery from the European Space Agency's Rosetta spacecraft reveal ice and dust on the surface of Comet 67P/Churyumov-Gerasimenko. The images were captured on June 1, 2016, over the course of 25 minutes at an altitude of roughly 13 km above the surface of the comet. Comet 67P is a Jupiter-family comet originally from the Kuiper belt and has an orbital period of 6.45 years.
The majority of the "snow" is actually caused by cosmic rays hitting the camera sensor and saturating pixels. These high energy particles pervade the Universe and originate from extrasolar phenomena such as supernovae, galactic nuclei, quasars, and gamma-ray bursts. The Earth's atmosphere protects us from the deleterious effects of cosmic rays.
