ʻImiloa Astronomy Center
ʻImiloa Astronomy Center is an astronomy and culture education center located in Hilo, Hawaii. Conceived by founding Director George Jacob in 2001, it features exhibits and shows dealing with Native Hawaiians, Hawaiian culture and history, astronomy (particularly at the Mauna Kea Observatories), and the overlap between the two. ʻImiloa includes a 120-seat planetarium, which features a fulldome video projection system. Planetarium presentations include ʻImiloa's exclusive signature show, "Maunakea: Between Earth and Sky." The bilingual exhibits (in Hawaiian and English) offer two views of Origins and Voyages, presenting the tools, visions and discoveries of the astronomers and the Polynesian voyagers (see Polynesian navigation), the first group of whom are thought to have voyaged to Hawaii from the Marquesas Islands. Visitors to ʻImiloa will leave with a new understanding of the early Polynesians, who used the stars to find these isolated islands in the middle of the vast P ...

Big Bang
The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. Various cosmological models based on the Big Bang concept explain a broad range of phenomena, including the abundance of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure. The uniformity of the universe, known as the horizon and flatness problems, is explained through cosmic inflation: a phase of accelerated expansion during the earliest stages. A wide range of empirical evidence strongly favors the Big Bang event, which is now essentially universally accepted.: "At the same time that observations tipped the balance definitely in favor of the relativistic big-bang theory, ..." Detailed measurements of the expansion rate of the universe place the Big Bang singularity at an estimated billion years ago, which is considered the age of the universe. Extrapolating this cosmic expansion backward in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
541132 Leleākūhonua
541132 Leleākūhonua () ( provisional designation ) is an extreme trans-Neptunian object and sednoid in the outermost part of the Solar System. It was first observed on 13 October 2015, by astronomers at the Mauna Kea Observatories, Hawaii. Based on its discovery date near Halloween and the letters in its provisional designation , the object was informally nicknamed "The Goblin" by its discoverers and later named Leleākūhonua, comparing its orbit to the flight of the Pacific golden plover. It was the third sednoid discovered, after and , and measures around in diameter. Discovery Leleākūhonua was first observed on 13 October 2015 at the Mauna Kea Observatory , by American astronomers David Tholen, Chad Trujillo and Scott Sheppard during their astronomical survey for objects located beyond the Kuiper Cliff. The unofficial discovery was publicly announced on 1 October 2018. The survey uses two principal telescopes: For the Northern hemisphere, the 8.2-meter Subaru T ...

514107 Kaʻepaokaʻawela
514107 Kaepaokaāwela (), provisional designation in astronomy, provisionally designated and nicknamed Bee-Zed, is a small asteroid, approximately in diameter, in a resonant, co-orbital motion with Jupiter. It is an unusual minor planet in that its orbit is Retrograde and prograde motion, retrograde, which is opposite to the direction of most other bodies in the Solar System. It was discovered on 26 November 2014, by astronomers of the Pan-STARRS survey at Haleakala Observatory on the island of Maui, United States. Kaepaokaāwela is the first example of an asteroid in a 1:–1 orbital resonance, resonance with any of the planets. This type of resonance had only been studied a few years before the object's discovery. One study suggests that it was an interstellar asteroid captured 4.5 billion years ago into an orbit around the Sun. Nomenclature The Hawaiian name ''Kaepaokaāwela'' is composed of ''ka'' 'the', ''epa'' 'tricky' or 'mischievous', referring to its contrary orb ...
