Mira

Mira (/ˈmaɪrə/, also known as Omicron Ceti, ο Ceti, ο Cet) is a red giant star estimated 200–400 light years away in the constellation Cetus. Mira is a binary star, consisting of the red giant Mira A along with Mira B. Mira A is also an oscillating variable star and was the first non-supernova variable star discovered, with the possible exception of Algol. Mira is the brightest periodic variable in the sky that is not visible to the naked eye for part of its cycle. Its distance is uncertain; pre-Hipparcos estimates centered on 220 light-years; while Hipparcos data from the 2007 reduction suggest a distance of 299 light-years, with a margin of error of 11%.

Observation history

Evidence that the variability of Mira was known in ancient China, Babylon or Greece is at best only circumstantial. What is certain is that the variability of Mira was recorded by the astronomer David Fabricius beginning on August 3, 1596. Observing what he thought was the planet Mercury (later identified as Jupiter), he needed a reference star for comparing positions and picked a previously unremarked third-magnitude star nearby. By August 21, however, it had increased in brightness by one magnitude, then by October had faded from view. Fabricius assumed it was a nova, but then saw it again on February 16, 1609.

Mira (film)

Mira is a 1971 Dutch-Belgian drama film directed by Fons Rademakers. It was entered into the 1971 Cannes Film Festival. The film was selected as the Dutch entry for the Best Foreign Language Film at the 44th Academy Awards, but was not accepted as a nominee.

IBM Mira

Mira is a petascale Blue Gene/Q supercomputer. As of June 2013, it is listed on TOP500 as the fifth-fastest supercomputer in the world. It has a performance of 8.59 petaflops (LINPACK) and consumes 3.9 MW. The supercomputer was constructed by IBM for Argonne National Laboratory's Argonne Leadership Computing Facility with the support of the United States Department of Energy, and partially funded by the National Science Foundation. Mira will be used for scientific research, including studies in the fields of material science, climatology, seismology, and computational chemistry. The supercomputer is being utilized initially for sixteen projects, selected by the Department of Energy.

The Argonne Leadership Computing Facility, which commissioned the supercomputer, was established by the America COMPETES Act, signed by President Bush in 2007, and President Obama in 2011. The United States' emphasis on supercomputing has been seen as a response to China's progress in the field. China's Tianhe-1A, located at the Tianjin National Supercomputer Center, was ranked the most powerful supercomputer in the world from October 2010 to June 2011. Mira is, along with IBM Sequoia and Blue Waters, one of three American petascale supercomputers deployed in 2012.

Sony Alpha 100

Sony α100 (DSLR-A100) is the first digital single-lens reflex camera (DSLR) marketed by Sony. It is successor to previous Konica Minolta DSLR models (primarily the Maxxum/Dynax 5D and 7D) through Sony's purchase of the Konica Minolta camera division. The α100 retains similar body design and claimed improvements on Konica Minolta's Anti-Shake sensor shifting image stabilization feature, renamed Super SteadyShot. It uses a 10.2 megapixels APS-C size CCD sensor. Another notable feature inherited from Konica Minolta is Eyestart, which provides for automatic autofocus activation by detecting the presence of the photographer's eye on the viewfinder, thus quickening camera response.

Another notable feature is an automatically vibrating CCD to remove dust each time the camera is shut off. The α100 shipped from Sony and resellers by the end of July 2006 with MSRP prices of US$1000 with the 18–70 mm f/3.5–f/5.6 kit lens and US$900 body only. The camera retains the same autofocus lens mount that was introduced with the Minolta Maxxum 7000 in 1985, allowing the continued use of the millions of existing Minolta AF lenses.
