Hubble Space Telescope
The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft. Hubble features a mirror, and its five main instruments observe in the ultraviolet, visible, and near-infrared regions of the electromagnetic spectrum. Hubble's orbit outside the distortion of Earth's atmosphere allows it to capture extremely high-resolution images with substantially lower background light than ground-based telescopes. It has recorded some of the most detaile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arrernte People
The Arrernte () people, sometimes referred to as the Aranda, Arunta or Arrarnta, are a group of Aboriginal Australian peoples who live in the Arrernte lands, at ''Mparntwe'' (Alice Springs) and surrounding areas of the Central Australia region of the Northern Territory. Many still speak one of the various Arrernte dialects. Some Arrernte live in other areas far from their homeland, including the major Australian cities and overseas. Arrernte mythology and spirituality focuses on the landscape and The Dreaming. Altjira is the creator being of the Inapertwa that became all living creatures. Tjurunga are objects of religious significance. The Arrernte Council is the representative and administrative body for the Arrernte Lands and is part of the Central Land Council. Tourism is important to the economy of Alice Springs and surrounding communities. Arrernte languages "Aranda" is a simplified, Australian English approximation of the traditional pronunciation of the name of ...

Dreamtime
The Dreaming, also referred to as Dreamtime, is a term devised by early anthropologists to refer to a religio-cultural worldview attributed to Australian Aboriginal mythology, Australian Aboriginal beliefs. It was originally used by Francis James Gillen, Francis Gillen, quickly adopted by his colleague Walter Baldwin Spencer, Baldwin Spencer and thereafter popularised by A. P. Elkin, who, however, later revised his views. The Dreaming is used to represent Aboriginal concepts of ''Everywhen'', during which the land was inhabited by ancestral figures, often of heroic proportions or with supernatural abilities. These figures were often distinct from gods, as they did not control the material world and were not worshipped but only reverence (emotion), revered. The concept of the Dreamtime has subsequently become widely adopted beyond its original Australian context and is now part of global popular culture. The term is based on a rendition of the Arandic languages, Arandic word '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Homogeneous
Homogeneity and heterogeneity are concepts often used in the sciences and statistics relating to the uniformity of a substance or organism. A material or image that is homogeneous is uniform in composition or character (i.e. color, shape, size, weight, height, distribution, texture, language, income, disease, temperature, radioactivity, architectural design, etc.); one that is heterogeneous is distinctly nonuniform in at least one of these qualities. Heterogeneous Mixtures, in chemistry, is where certain elements are unwillingly combined and, when given the option, will separate. Etymology and spelling The words ''homogeneous'' and ''heterogeneous'' come from Medieval Latin ''homogeneus'' and ''heterogeneus'', from Ancient Greek ὁμογενής (''homogenēs'') and ἑτερογενής (''heterogenēs''), from ὁμός (''homos'', “same”) and ἕτερος (''heteros'', “other, another, different”) respectively, followed by γένος (''genos'', “kind”); - ...

Deep Ecliptic Survey
The Deep Ecliptic Survey (DES) is a project to find Kuiper belt objects (KBOs), using the facilities of the National Optical Astronomy Observatory (NOAO). The principal investigator is Robert L. Millis. Since 1998 through the end of 2003, the survey covered 550 square degrees with Apparent magnitude, sensitivity of 22.5, which means an estimated 50% of objects of this magnitude have been found. The survey has also established the mean Kuiper Belt plane and introduced new cubewano#Toward a formal definition, formal definitions of the dynamical classes of Kuiper belt objects. The remarkable first observations and/or discoveries include: * 28978 Ixion, large plutino * 19521 Chaos (cubewano) * , the first Binary asteroid, binary trans-Neptunian object (TNO) * , the first object with perihelion too far to be affected (scattered) by Neptune and a large semi-major axis * , remarkable for its semi-major axis of more than 500 astronomical unit, AU and extreme orbital eccentricity, eccentr ...

Classical Kuiper Belt Object
A classical Kuiper belt object, also called a cubewano ( "QB1-o"), is a low-eccentricity Kuiper belt object (KBO) that orbits beyond Neptune and is not controlled by an orbital resonance with Neptune. Cubewanos have orbits with semi-major axes in the 40–50 AU range and, unlike Pluto, do not cross Neptune's orbit. That is, they have low-eccentricity and sometimes low-inclination orbits like the classical planets. The name "cubewano" derives from the first trans-Neptunian object (TNO) found after Pluto and Charon: 15760 Albion, which until January 2018 had only the provisional designation (15760) 1992 QB1. Similar objects found later were often called "QB1-o's", or "cubewanos", after this object, though the term "classical" is much more frequently used in the scientific literature. Objects identified as cubewanos include: * 15760 Albion (aka 1992 QB1 and gave rise to term 'Cubewano') * 136472 Makemake, the largest known cubewano and a dwarf planet * 50000 Quaoar an ...

Degree (angle)
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane (mathematics), plane angle in which one Turn (geometry), full rotation is 360 degrees. It is not an SI unit—the SI unit of angular measure is the radian—but it is mentioned in the SI Brochure, SI brochure as an Non-SI units mentioned in the SI, accepted unit. Because a full rotation equals 2 radians, one degree is equivalent to radians. History The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year. Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day. Some ancient calendars, such as the Iranian calendar, Persian calendar and the Babylonian calendar, used 360 days for a year. ...
