If he were alive today, legendary photographer Henri Cartier-Bresson would marvel at all the choices a modern shooter must make before arriving at "the decisive moment." The roadblocks to creativity we place before ourselves are more prevalent than ever. Camera makers update their lenses, sensors, and formats with over whelming frequency. We can read hundreds of expert (and not-so-expert) opinions on every new piece of gear before we even begin to think about where to point the thing and when to press the shutter. While we all search for the one camera system that will somehow allow us to elevate our technique, a humble and ingenious solution has been here the whole time, ready for us to embrace or rediscover its beautiful simplicity: the 50-mm lens.
The electromagnetic spectrum is the highway over which wireless operates, with multiple lanes capable of carrying traffic at different speeds. Higher frequencies – and thus shorter wavelengths – are able to move more information per unit of time. Millimeter or extremely high frequency (EHF) waves, occupy the relatively unused portion of the electromagnetic spectrum between 30 GHz and 300 GHz, which offers greater throughput and thus higher overall capacity than the increasingly crowded WiFi bands under 6 GHz. Historically, millimeter-wave technology has been expensive and difficult to deploy, which has limited it to niche applications like radio astronomy, microwave remote sensing and terrestrial fixed communications. More recently, however, interest has increased significantly as those two obstacles have been largely overcome.
At the top, on a wooden tripod, is a 70 millimeter high-speed motorized Hulcher camera used at sporting events. The three cameras on the bottom, from left, are a 1940s-era Fairchild K-10 aerial camera that used 5x7-inch roll film; a 1980s-era Nikon F3 35 millimeter camera; and a 1950s-era Rolleiflex 120 millimeter film camera. This photo by staff photographer Randy McBride appeared in the 1987 Los Angeles Times book "Images of Our Times: Sixty Years of Photography from the Los Angeles Times." In the upper left of the photo is an early 300 millimeter lens but the brand was not identified.
There's a planet just over 4 light-years away orbiting a star at just the right distance--not too close, not too far--that it could support liquid water on its surface. We don't know much about its atmosphere, if it even has one, and we're trying to figure out more about its interior. There's a lot more to uncover, but it sure sounds like it could be a promising place to find some alien neighbors, right?
At the edge of our solar system, there is a lonely dwarf world wandering through space. Named DeeDee by astronomers, the distant dwarf takes 1,100 years to complete just one orbit of the sun and has a surface temperature of a chilly -243 C (-406 F). The small planet-like object was recently spotted by scientists using the Atacama Large Millimeter/submillimeter Array (Alma) telescope, and could even help shed light on how our solar system began. DeeDee is wandering around 86 billion miles (137 billion kilometres) from Earth, new observations have found. The object is two-thirds the size of Ceres, the biggest dwarf planet in our asteroid belt, and is thought to be spherical.
