A space mission by → NASA whose main goal is to study the → dwarf planet Pluto and it satellites.

It flew 12,500 km above the surface of Pluto, making it the first spacecraft to explore the dwarf planet. Its science payload includes seven instruments: Ralph (visible and infrared imager/spectrometer), Alice (ultraviolet imaging spectrometer), REX (Radio Science EXperiment), LORRI (Long Range Reconnaissance Imager), SWAP (Solar Wind Around Pluto), PEPSSI: (Pluto Energetic Particle Spectrometer Science Investigation), and SDC: (Student Dust Counter). As part of an extended mission, New Horizons has maneuvered for a flyby of → Kuiper belt object 2014 MU69, expected to take place on January 1, 2019, when it is 43.4 → astronomical units (AU) from the Sun.

new; → horizon.

new moon
  نومانگ، مانگ ِ نو   
nowmâng (#), mâng-e now (#)

Fr.: nouvelle lune   

The Moon's phase when it is at the same celestial longitude as the Sun and thus totally un-illuminated as seen from Earth.

new; → moon.

newton
  نیوتن   
newton (#)

Fr.: newton   

The unit of force in the SI system of units. 1 newton (N) is defined as the force required to give a mass of 1 kilogram an acceleration of 1 m s-2. 1 N = 105  → dynes.

Named after Sir Isaac Newton (1642-1727), the English highly prominent physicist and mathematician.

Newton constant
  پایای ِ نیوتن   
pâyâ-ye Newton

Fr.: constante de Newton   

Same as the → gravitational constant.

Newton; → constant.

Newton's color wheel
  چرخ ِ رنگ ِ نیوتن   
carx-e rang-e Newton

Fr.: disque de Newton   

The arrangement of the seven colors of the rainbow on a disk. When the disk rotates very fast, the eye cannot distinguish between individual colors and the disk is perceived as white. This apparatus demonstrates the discovery made by Newton (Opticks, 1704) that light is composed of seven colors.

Newton; → color; → wheel.

Newton's constant
  پایای ِ نیوتون   
pâyâ-ye Newton

Fr.: constante de Newton   

Same as the → gravitational constant.

Newton; → constant.

Newton's cradle
  گهواره‌ی ِ نیوتون   
gahvâre-ye Newton

Fr.: pendule de Newton   

A device consisting of a series of equal → pendulums in a row used to demonstrate the laws of → conservation of momentum and → conservation of energy.

Newton; → cradle.
