The Soviet MiG-29s are, for the first time, traveling to the Abbotsford International Airshow in Abbotsford, BC, Canada, to participate in the August 1989 airshow. The USAF F-15 Eagle interceptors actively guarding North American and United States of America's airspace are with the 21st Tactical Fighter Wing, headquartered at Elmendorf Air Force Base (AFB), Alaska, USA.

What's up in the sky this winter? The featured graphic gives a few highlights for Earth's northern hemisphere. Viewed as a clock face centered at the bottom, early winter sky events fan out toward the left, while late winter events are projected toward the right. Objects relatively close to Earth are illustrated, in general, as nearer to the cartoon figure with the telescope at the bottom center -- although almost everything pictured can be seen without a telescope. Highlights of this winter's sky include the Geminids meteor shower peaking this week, the constellation of Orion becoming notable in the evening sky, and many planets being visible before sunrise in February. As true in every season, the International Space Station (ISS) can be sometimes be found drifting across your sky if you know just when and where to look. via NASA

Wikipedia picture of the day on December 11, 2017: Night view of Berlin Hauptbahnhof (English: Berlin Central Station), main railway station in Berlin, Germany. The station came into full operation in May 2006 and is located on the site of the historic Lehrter Bahnhof, which was opened in 1871 as the terminus of the railway linking Berlin with Lehrte (location near Hanover), which later became Germany's most important east-west main line. In 1987, it was extensively renovated to commemorate Berlin's 750th anniversary, and again in 2006 to its current appearance. Wikipedia"

This composition in stardust covers over 8 degrees on the northern sky. The mosaicked field of view is west of the familiar Pleiades star cluster, toward the zodiacal constellation Aries and the plane of our Milky Way Galaxy. At right in the deep skyscape is bluish Epsilon Arietis, a star visible to the naked-eye and about 330 light-years away. Reflecting starlight in the region, dusty nebulae LBN762, LBN753, and LBN743 sprawl left to right across the field, but are likely some 1,000 light-years away. At that estimated distance, the cosmic canvas is over 140 light-years across. Near the edge of a large molecular cloud, their dark interiors can hide newly formed stars and young stellar objects or protostars from prying optical telescopes. Collapsing due to self-gravity, the protostars form around dense cores embedded in the molecular cloud. via NASA
