Hubble Optics 5-Star Artificial Star for Testing and Collimating Telescopes After all the trouble, due to turbulence, the real star may not even reveal the true quality of your telescopes or give you perfect collimation. An artificial star will provide you with an excellent alternative means to do the star test anytime and anywhere you want, without all the drawbacks of real stars.

Art silk Artificial silk or (as the term is used in the textile industry) art silk is any synthetic fiber which resembles silk, but typically costs less to produce. Frequently, artificial silk is just a synonym for rayon.When made out of bamboo viscose it is also sometimes called bamboo silk.lthough not sold under the name art silk initially, nylon, the first synthetic fiber, was developed in the United States in the late 1930s and used as a replacement for Japanese silk during World War II.

Satellite A full-size model of the Earth observation satellite ERS 2. In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as Earth's Moon.

What is Artificial Grass? The artificial turf system includes preparation of the ground the synthetic turf will be installed on, the drainage through the synthetic grass backing, the infill material used to keep the artificial grass blades erect and provide ballast, and the yarn that create the “fake-grass lawn” blades.

Artificial Satellites Artificial satellites are used to study the Earth, other planets, to help us communicate, and even to observe the distant Universe. Satellites can even have people in them, like the International Space Station and the Space Shuttle. The first artificial satellite was the Soviet Sputnik 1 mission, launched in 1957. Since then, dozens of countries have launched satellites, with more than 3,000 currently operating spacecraft going around the Earth.

Artificial island The Flevopolder in the Netherlands is 970 km² and is the largest island formed by reclaimed land in the world. An artificial island or man-made island is an island that has been constructed by people rather than formed by natural means. Artificial islands may vary in size from small islets reclaimed solely to support a single pillar of a building or structure, to those that support entire communities and cities.

Star Due to their great distance from the Earth, all stars except the Sun appear to the unaided eye as shining points in the night sky that twinkle because of the effect of the Earth's atmosphere. The Sun is also a star, but it is close enough to the Earth to appear as a disk instead, and to provide daylight.

- He described in detail the possible use of space stations for mass communication, how to launch satellites, what orbits they could use, and the benefits of having a network of world-circling satellites. The world's first artificial satellite, the Sputnik 1, was launched by the Soviet Union on October 4, 1957.

What is an Artificial Organ? This includes devices such as prostheses and cochlear implants, but the ultimate goal of artificial organ research and development is fully functional created organs that can be integrated into the body which fully replaces the natural organ and remains functional for a lifetime.

Equinox A star is a luminous sphere of plasma held together by its own gravity. The nearest star to Earth is the Sun. Other stars are visible from Earth during the night, appearing as a multitude of fixed luminous points in the sky due to their immense distance from Earth.he color of a star, as determined by the most intense frequency of the visible light, depends on the temperature of the star's outer layers, including its photosphere. Besides visible light, stars also emit forms of electromagnetic radiation that are invisible to the human eye.

What is Artificial Intelligence? Artificial Intelligence (AI) is usually defined as the science of making computers do things that require intelligence when done by humans. AI has had some success in limited, or simplified, domains. However, the five decades since the inception of AI have brought only very slow progress, and early optimism concerning the attainment of human-level intelligence has given way to an appreciation of the profound difficulty of the problem.

Satellite (artificial) Satellites are objects orbiting a planet. The moon is a natural satellite. Artificial satellites are those put into orbit by man. The first artificial satellite was Sputnik I launched by the Soviet Union in 1957. Now almost fifty years later there are thousands of satellites orbiting the Earth at various heights.
