The Perseid meteor shower, which is caused by meteoroids crashing and burning high in Earth's upper atmosphere, will produce the greatest activity after 2 a.m. Tuesday. The show will continue into the early morning hours with the rate of meteors eventually reaching one to two meteors every minute.
Central Michigan University astronomer Christopher Tycner is available to comment on the origin of this annual meteor shower and how it can best be observed.
* "The Perseid meteors are the debris of a comet that is now far away from the sun where it spends most of its life in the coldness of space. However, during the Perseid shower, the Earth passes through the trail of dust debris that the comet left behind many years ago."
* "When one of these dust particles is intercepted by our planet as it orbits the sun, it causes the dust particle to completely burn up, leaving an eye-catching streak of light."
* "Perseid meteors appear to originate from the direction of the constellation Perseus, which rises in the northeast. The best view is in this direction and far away from city lights. Onlookers should find a safe dark site, such as a city or state park, where oncoming vehicle headlights won't interfere."
Tycner came to CMU from the U.S. Naval Observatory, Flagstaff Station in 2007. He specializes in observational stellar astrophysics and studies circumstellar disks of hot stars using a variety of ground-based instruments including long-baseline optical interferometry and spectroscopy.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
