General Dynamics F-16 Fighting Falcon family of multi-role fighter aircraft

The General Dynamics F-16 Fighting Falcon is a single-engine multirole fighter aircraft originally developed by General Dynamics for the United States Air Force (USAF). Designed as an air superiority day fighter, it evolved into a successful all-weather multirole aircraft. Over 4,600 aircraft have been built since production was approved in 1976. Although no longer being purchased by the U.S. Air Force, improved versions are being built for export customers. In 1993, General Dynamics sold its aircraft manufacturing business to the Lockheed Corporation, which in turn became part of Lockheed Martin after a 1995 merger with Martin Marietta.

Meiklejohn Glacier is a glacier, 12 nautical miles (22 km) long and 4 nautical miles (7 km) wide, flowing southwest from the Dyer Plateau of Palmer Land, Antarctica, to George VI Sound, immediately south of Moore Point. In its lower reaches the south side of this glacier merges with Millett Glacier. It was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Rymill, and was named by the UK Antarctic Place-Names Committee in 1954 for Ian F. Meiklejohn, a radio operator of the BGLE.

McCleary Glacier is a broad glacier about 10 nautical miles (20 km) long, draining southward into Darwin Glacier, Antarctica, just west of Tentacle Ridge. It was mapped by the United States Geological Survey from tellurometer surveys and Navy air photos, 1959–63, and was named by the Advisory Committee on Antarctic Names for George McCleary, a public information officer on the staff of the U.S. Antarctic Projects Officer (USAPO) (1959–61), whose labors helped to start the Bulletin of the USAPO.

Theta Coronae Borealis, Latinized from θ Coronae Borealis, is a binary star system in the constellation Corona Borealis. It shines with a combined apparent visual magnitude of 4.13. There are two components: Theta Coronae Borealis A is of apparent magnitude 4.16, while Theta Coronae Borealis B lies around 1 arcsecond distant and has an apparent magnitude of 6.29. The system is located around 375 light-years from Earth, as estimated from its parallax of 8.69 milliarcseconds. It is estimated to be 85 million years old, with the primary star expected to remain on the main sequence burning its core hydrogen for another 75 million years and the secondary around 500 million years. Both stars will cool and expand once their core hydrogen is exhausted, becoming red giants.

Nu Eridani is a star in the constellation Eridanus. It is visible to the naked eye with an apparent visual magnitude of 3.93. The distance to this star is roughly 520 light years, based upon an annual parallax shift of 0.00625 arcseconds. If the star were 33 ly (10 pc) from the Sun, it would be the brightest star in the night sky with an apparent magnitude of −2.84.
