Benjamin Franklin Drawing Electricity from the Sky is a c. 1805 painting by Benjamin West in the Philadelphia Museum of Art. [1] It depicts American Founding Father Benjamin Franklin conducting his kite experiment in 1752 to ascertain the electrical nature of lighting. West composed his 13.25 in × 10 in (33.7 cm × 25.4 cm) work using oil on a ...
On 21 March 2013, the European-led research team behind the Planck cosmology probe released the mission's all-sky map of the cosmic microwave background. [ 26 ] [ 27 ] This map suggests the Universe is slightly older than thought: according to the map, subtle fluctuations in temperature were imprinted on the deep sky when the Universe was about ...
The new name refers to the pupil of an eye, and to a legend of a painting of four dragons.

Ranger 5 was a Block II Ranger spacecraft similar to Ranger 3 and Ranger 4.The basic vehicle was 3.1 m high and consisted of a lunar capsule covered with a balsawood impact-limiter, 65 cm in diameter, a mono-propellant mid-course motor, a retrorocket with a thrust of 5,080 lbf (22.6 kN), and a gold and chrome plated hexagonal base 1.5 m in diameter.
Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of approximately 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System.
Like a great painting or an abiding institution, it has acquired an existence of its own, a destiny beyond the grasp of its handlers. — Stephen J.

The Cosmic Background Explorer (COBE / ˈ k oʊ b i / KOH-bee), also referred to as Explorer 66, was a NASA satellite dedicated to cosmology, which operated from 1989 to 1993.Its goals were to investigate the cosmic microwave background radiation (CMB or CMBR) of the universe and provide measurements that would help shape the understanding of the cosmos.
The mission was planned to create infrared images of 99% of the sky, with at least eight images made of each position on the sky in order to increase accuracy. The spacecraft was placed in a 525 km (326 mi), circular, polar, Sun-synchronous orbit for its ten-month mission, during which it has taken 1.5 million images, one every 11 seconds. [ 19 ]
