The contacts of all relays in a signal box are cleaned by hand once a year. During the night, when there are large time windows between switching operations With a rag, that goes very quickly. When you look closely, there are small black dots that then disappear. This happens regardless of whether the respective contacts are actually used in a circuit or not. There are contacts that toggle several times for each train journey, those that toggle only a few times a month, and those that only toggle on rare occasions. About every 10 years, the relay sets are revised and replaced by overhauled ones. By far, the most often toggled the feedback relays from the railway barrier flashing lights. As long as the alternating blinker flashes at a barrier, these relays wobble, as can be seen in the video. Switzerland, January 18, 2022. (12/13),

Meteors streak by and the Milky Way shifts its position in the night sky, as seen in this time-lapse video from Crook Point on the southern Oregon Coast, Aug. 13, 2020. Peter Pearsall, USFWS video The Perseids, as they are known, are visible every summer from the Northern Hemisphere and are considered the best meteor shower of the year, according to NASA. At its peak, the shower can contain up to 100 meteors per hour. Although the meteor showers are active starting in mid-July, the best time to view them is in mid-August, and usually in the early morning hours. Just south of Gold Beach and only 30 minutes from the California border, Crook Point was acquired by the U.S. Fish and Wildlife Service in 2000 to protect rare plants, seabird colonies and a 1-mile-long stretch of beach from encroaching development. The 134-acre Crook Point parcel is part of the Oregon Islands National Wildlife Refuge and right next to the Mack Reef archipelago, which is home to the second largest concentration of nesting seabirds in the state. In addition to rare plants, seabird habitat, and unique geologic formations, the headland at Crook Point also protects a small stream with native cutthroat trout. The scenic and extensive Oregon Islands Refuge includes more than 1,800 rocks, reefs, and islands, stretching from Tillamook Head all the way south to the California border. All of the rocks, including the famous ones named Haystack, are designated as wilderness areas, too. The headland at Crook Point is closed to public use.

A magnetic filament of solar material erupted on the sun in late September, breaking the quiet conditions in a spectacular fashion. The 200,000 mile long filament ripped through the sun's atmosphere, the corona, leaving behind what looks like a canyon of fire. The glowing canyon traces the channel where magnetic fields held the filament aloft before the explosion. Visualizers at NASA's Goddard Space Flight Center in Greenbelt, Md. combined two days of satellite data to create a short movie of this gigantic event on the sun. In reality, the sun is not made of fire, but of something called plasma: particles so hot that their electrons have boiled off, creating a charged gas that is interwoven with magnetic fields. These images were captured on Sept. 29-30, 2013, by NASA's Solar Dynamics Observatory, or SDO, which constantly observes the sun at a variety of wavelengths.

The International Astronomical Union's book and movie celebrating the 400th anniversary of the telescope The Eyes on the Skies movie explores the many facets of the telescope: the historical development, the scientific importance, the technological breakthroughs, and also the people behind this ground-breaking invention, their triumphs and failures. The Eyes on the Skies movie is presented by Dr. J, aka Dr. Joe Liske, from ESO, host of the Hubblecast video podcast. It runs for 60 minutes.
