Killarney Provincial Park Observatory
The Killarney Provincial Park Observatory is an astronomical observatory located at the George Lake Campground of Killarney Provincial Park (a 420 km drive north of Toronto or a 100 km drive southwest of Sudbury). The Observatory is operated by Ontario Parks and houses two observatory buildings. The original facility contains a 10" telescope with solar filter, ideal for nighttime as well as daytime viewing of the Sun. The newer facility (built in 2018) contains a 16" fully automated telescope with a 5" refractor and is ideal for research, astrophotography and public use. The telescopes are available for Discovery programs (formally known as Natural Heritage Education (NHE) programs) as well as private sign-out (self-use) by interested visitors. Astronomy in Killarney Provincial Park Astronomy education began in the Park in 1985 as part of outreach programs provided by Bruce Waters on behalf of the McLaughlin Planetarium. Interest in the astronomy programs quickly grew w ...

Killarney, Ontario
Killarney is a municipality located on the northern shore of Georgian Bay in the Sudbury District of Ontario, Canada. Killarney is commonly associated with Killarney Provincial Park, which is a large wilderness park located to the east of the townsite which occupies much of the municipality's expanded boundary. In addition to the community of Killarney itself, the communities of Hartley Bay and Bigwood, and the ghost towns of French River, Collins Inlet and Key Harbour, are also located within the municipal boundaries. The eastern end of the La Cloche Mountain Range is also located within the municipality of Killarney. History Killarney's established community was founded in 1820 by Etienne De La Morandiere (although indigenous peoples were living there prior), a French Canadian originally from Varennes, Quebec and a fur trader in Sault St Marie, Michigan, along with his wife Josette Sai Sai Go No Kwe, an indigenous woman from Michigan and a close relative of Chief Kitchi, mean ...

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during ...

Dark-sky Preserve
A dark-sky preserve (DSP) is an area, usually surrounding a park or observatory, that restricts artificial light pollution. The purpose of the dark-sky movement is generally to promote astronomy. However, astronomy is certainly not the only objective of conserving a dark sky. A dark night sky is associated with many facets of history, philosophy, religion, societal development, poetry, song, mathematics, and science. Different terms have been used to describe the areas as national organizations have worked independently to create their programs. The International Dark-Sky Association (IDA) uses International Dark Sky Reserve (IDSR) and International Dark Sky Park (IDSP). A third designation, International Dark Sky Sanctuary, was introduced in 2015. History An International Dark-Sky Association (IDA) was founded in 1988 to reserve public or private land for an exquisite outlook of nocturnal territories and starry night skies. These reserves are specifically conserved for its sci ...

Presolar Grains
Presolar grains are interstellar solid matter in the form of tiny solid grains that originated at a time before the Sun was formed. Presolar stardust grains formed within outflowing and cooling gases from earlier presolar stars. The stellar nucleosynthesis that took place within each presolar star gives to each granule an isotopic composition unique to that parent star, which differs from the isotopic composition of our solar system's matter as well as from the galactic average. These isotopic signatures often fingerprint very specific astrophysical nuclear processes that took place within the parent star and prove their presolar origin. Terminology Meteoriticists often use the term to represent ''stardust'', grains that originated within a single star and which they extract from meteorites for study. Because most interstellar grains are not stardust from a single star, however, being instead interstellar cloud matter accreted by smaller presolar grains, most presolar grains a ...

Allende Meteorite
The Allende meteorite is the largest carbonaceous chondrite ever found on Earth. The fireball was witnessed at 01:05 on February 8, 1969, falling over the Mexican state of Chihuahua. After it broke up in the atmosphere, an extensive search for pieces was conducted and over 2 tonnes (2.2 tons) were recovered. The availability of large quantities of samples of the scientifically-important chondrite class has enabled numerous investigations by many scientists; it is often described as "the best-studied meteorite in history." The Allende meteorite has abundant, large calcium–aluminium-rich inclusions (CAI), which are among the oldest objects formed in the Solar System. Carbonaceous chondrites compose about 4 percent of all meteorites observed to fall from space. Prior to 1969, the carbonaceous chondrite class was known from a small number of uncommon meteorites such as Orgueil, which fell in France in 1864. Meteorites similar to Allende were known, but many were small and poorl ...

Iron Meteorite
Iron meteorites, also known as siderites, or ferrous meteorites, are a type of meteorite that consist overwhelmingly of an iron–nickel alloy known as meteoric iron that usually consists of two mineral phases: kamacite and taenite. Most iron meteorites originate from cores of planetesimals, with the exception of the IIE iron meteorite group The iron found in iron meteorites was one of the earliest sources of usable iron available to humans, due to the malleability and ductility of the meteoric iron, before the development of smelting that signaled the beginning of the Iron Age. Occurrence Although they are fairly rare compared to the stony meteorites, comprising only about 5.7% of witnessed falls, iron meteorites have historically been heavily over-represented in meteorite collections. This is due to several factors: * They are easily recognized as unusual even by laymen, as opposed to stony meteorites. Modern-day searches for meteorites in deserts and Antarctica yield a muc ...

Dark Sky Preserves
Darkness, the direct opposite of lightness, is defined as a lack of illumination, an absence of visible light, or a surface that absorbs light, such as black or brown. Human vision is unable to distinguish colors in conditions of very low luminance. This is because the hue sensitive photoreceptor cells on the retina are inactive when light levels are insufficient, in the range of visual perception referred to as scotopic vision. The emotional response to darkness has generated metaphorical usages of the term in many cultures, often used to describe an unhappy or foreboding feeling. Referring to a time of day, complete darkness occurs when the Sun is more than 18° below the horizon, without the effects of twilight on the night sky. Scientific Perception The perception of darkness differs from the mere absence of light due to the effects of after images on perception. In perceiving, the eye is active, and the part of the retina that is unstimulated produces a complementary ...
