Comet 67P On 5 September 2014 - OSIRIS (15156592796)
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several milli ...

67P/Churyumov–Gerasimenko
67P/Churyumov–Gerasimenko (abbreviated as 67P or 67P/C–G) is a Jupiter-family comet, originally from the Kuiper belt, with a current orbital period of 6.45 years, a rotation period of approximately 12.4 hours and a maximum velocity of . Churyumov–Gerasimenko is approximately at its longest and widest dimensions. It was first observed on photographic plates in 1969 by Soviet astronomers Klim Ivanovych Churyumov and Svetlana Ivanovna Gerasimenko, after whom it is named. It most recently came to perihelion (closest approach to the Sun) on 2 November 2021, and will next come to perihelion on 9 April 2028. Churyumov–Gerasimenko was the destination of the European Space Agency's ''Rosetta'' mission, launched on 2 March 2004. ''Rosetta'' rendezvoused with Churyumov–Gerasimenko on 6 August 2014 and entered orbit on 10 September 2014. ''Rosetta'' lander, ''Philae'', landed on the comet's surface on 12 November 2014, becoming the first spacecraft to land on a comet nucleu ...

Max Planck Institute For Solar System Research
The Max Planck Institute for Solar System Research (abbreviation: MPS; german: Max-Planck-Institut für Sonnensystemforschung) is a research institute in astronomy and astrophysics located in Göttingen, Germany, where it relocated in February 2014 from the nearby village of Lindau. The exploration of the Solar System is the central theme for research done at this institute. MPS is a part of the Max Planck Society, which operates 80 research facilities in Germany. Research MPS is organised in three departments: Sun and Heliosphere, Planets and Comets, and Solar and Stellar Interiors. In addition, since 2002 there is also an International Max Planck Research School. Subjects of research at the institute are the various objects within the solar system. A major area of study concerns the Sun, its atmosphere, the interplanetary medium as influenced by the solar wind, as well as the impact of solar particles and radiation on the planets. The second area of research involves the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Livestream
Livestreaming is streaming media simultaneously recorded and broadcast in real-time over the internet. It is often referred to simply as streaming. Non-live media such as video-on-demand, vlogs, and YouTube videos are technically streamed, but not live-streamed. Livestream services encompass a wide variety of topics, from social media to video games to professional sports. Platforms such as Facebook Live, Periscope, Kuaishou, Douyu, bilibili and 17 include the streaming of scheduled promotions and celebrity events as well as streaming between users, as in videotelephony. Sites such as Twitch have become popular outlets for watching people play video games, such as in esports, Let's Play-style gaming, or speedrunning. Live coverage of sporting events is a common application. User interaction via chat rooms forms a major component of livestreaming. Platforms often include the ability to talk to the broadcaster or participate in conversations in chat. Many chat rooms also consist ...

Field Of View
The field of view (FoV) is the extent of the observable world that is seen at any given moment. In the case of optical instruments or sensors it is a solid angle through which a detector is sensitive to electromagnetic radiation. Humans and animals In the context of human and primate vision, the term "field of view" is typically only used in the sense of a restriction to what is visible by external apparatus, like when wearing spectacles or virtual reality goggles. Note that eye movements are allowed in the definition but do not change the field of view when understood this way. If the analogy of the eye's retina working as a sensor is drawn upon, the corresponding concept in human (and much of animal vision) is the visual field. It is defined as "the number of degrees of visual angle during stable fixation of the eyes".Strasburger, Hans; Pöppel, Ernst (2002). Visual Field. In G. Adelman & B.H.

Charge-coupled Device
A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging. In a CCD image sensor, pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors. These MOS capacitors, the basic building blocks of a CCD, are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges. Although CCDs are not the only technology to allow for light detection, CCD image sensors are widely used in professional, medical, and scientific applications where high-quality image data are required. In applications with less exacting quality demands, such as consumer and professional digital cameras, act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VIRTUOSO
A virtuoso (from Italian ''virtuoso'' or , "virtuous", Late Latin ''virtuosus'', Latin ''virtus'', "virtue", "excellence" or "skill") is an individual who possesses outstanding talent and technical ability in a particular art or field such as fine arts, music, singing, playing a musical instrument, or composition. Meaning This word also refers to a person who has cultivated appreciation of artistic excellence, either as a connoisseur or collector. The plural form of ''virtuoso'' is either ''virtuosi'' or the Anglicisation ''virtuosos'', and the feminine forms are ''virtuosa'' and ''virtuose''. According to ''Music in the Western civilization'' by Piero Weiss and Richard Taruskin: ...a virtuoso was, originally, a highly accomplished musician, but by the nineteenth century the term had become restricted to performers, both vocal and instrumental, whose technical accomplishments were so pronounced as to dazzle the public. The defining element of virtuosity is the performance ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OSIRIS-REx
OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) is a NASA asteroid-study and sample-return mission. The mission's primary goal is to obtain a sample of at least from 101955 Bennu, a carbonaceous near-Earth asteroid, and return the sample to Earth for a detailed analysis. The material returned is expected to enable scientists to learn more about the formation and evolution of the Solar System, its initial stages of planet formation, and the source of organic compounds that led to the formation of life on Earth. OSIRIS-REx was launched on 8 September 2016, flew past Earth on 22 September 2017, and rendezvoused with Bennu on 3 December 2018. It spent the next several months analyzing the surface to find a suitable site from which to extract a sample. On 20 October 2020, OSIRIS-REx touched down on Bennu and successfully collected a sample. Though some of the sample escaped when the flap that should have clo ...
