Christian Mayer (1719-1783), Czech astronomer and teacher. (There is no known portrait of Mayer.) By invitation, Mayer observed the 1769 transit of Venus in St Petersburg. He was Court Astronomer at Mannheim (Germany) until the Jesuit order, of which he was one, was dissolved by the Pope. He was still able to continue his astronomical studies. His is known today for his study of double stars, of which he proposed some were true binaries orbiting each other.
Joint medal for Pierre Janssen and Norman Lockyer issued by the French Académie des Sciences. It was in recognition of their independent innovation of a method of studying the Sun when it was not eclipsed.

John Couch Adams (1819-18920 (Portrait: Hubert von Herkomer, c. 1888) Adams was an English astronomer and mathematician. Inspired by Mary Somerville, he calculated an orbit for an unknown planet disturbing the orbit of Uranus. Astronomers didn't find it, despite Adams's good calculations. But Johann Galle found it using LeVerrier's calculations.

Gene Shoemaker (1928-1997) donning a Bell rocket belt while training astronauts. Shoemaker was a geologist with a particular interest in asteroids and meteors and their craters, and one of the pioneers of planetary science. A possible candidate for an Apollo mission, he was ruled out on health grounds. Along with astronomer wife Carolyn and their friend David Levy, he was co-discoverer of a comet that crashed into Jupiter. After his death Lunar Prospector took some of his ashes to the Moon.

Rocket belt allowed a soldier to travel safely over a small distance. Created in the 1960s it seemed promising. During October 1961, it was demonstrated personally to President JF. Kennedy in the course of exponential maneuvers on military base Fort Bragg. By mid 60s, the military was no longer interested in the rocket belt. Because of its short range, the military axed it. Maximum duration of flight was 21secs, with a range of 120 m. Military lost interest bcuz aircraft tech was advancing.
Jan Hendrik Oort (1900-1992) was a Dutch astronomer who made significant contributions to the understanding of the Milky Way and who was a pioneer in the field of radio astronomy. The Oort Cloud is named for him, as he theorized the existence of this distant reservoir of long period comets.

Mary Somerville (1780-1872) was the foremost woman of science of her age, by both contemporary and modern standards. An astronomer, mathematician, and geographer, she was at the forefront of the transmission of new scientific and mathematical ideas and practices to the literate public of nineteenth century Great Britain through her books and scientific writings.

Vesto Melvin Slipher (1875 – 1969). Slipher, of the Lowell Observatory in Arizona, was the first to measure the radial velocities of what we now know are galaxies. He saw that M31 was blueshifted, and stated that it meant it was moving towards us. However he found that most of them were redshifted. This was the first evidence of what was later understood as the expansion of the Universe.

Carl McNair tells the story of his brother Ronald, an African American kid in the 1950s who set his sights on the stars. Ronald McNair, PhD in physics from MIT and accomplished musician, also became a NASA astronaut. He died when the shuttle Challenger broke up soon after launch on January 28, 1986.

Colin Pillinger (1943 - 2014) with the Beagle 2 landing craft in 2002. The space scientist was the driving power behind the Beagle 2 mission. The craft landed on Mars on Christmas Day 2003. It was never heard from again. Sadly, Pillinger never learned of Beagle's fate. It wasn't finally located until January 2015, using images from the HiRise camera on NASA's Mars Reconnaisance Orbiter.

Dr Subrahmanyan Chandrasekhar (1910 - 1995) Indian physicist, Nobel Prize winner in physics, the Chandra space telescope is named after him.
NASA's premier X-ray observatory was named the Chandra X-ray Observatory in honor of the late Indian-American Nobel laureate, Subrahmanyan Chandrasekhar, known to the world as Chandra. In 1983, Chandra was awarded the Nobel prize for his theoretical studies of the physical processes important to the structure and evolution of stars.- via NASA's Chandra X-ray Observatory's photo on Google+
Dr Subrahmanyan Chandrasekhar (1910 - 1995) Indian physicist, Nobel Prize winner in physics. One of the first scientists to couple the study of physics with the study of astronomy. Chandra proved that there was an upper limit to the mass of a white dwarf. Known as the Chandra limit, showed that stars more massive than the Sun would explode or form black holes as they died. Also developed theories on star atmospheres, black holes, the illumination of the sunlit sky, star structures, star mass.
Johannes Kepler was born on 27 December 1571 in Weil der Stadt, near Stuttgart in Germany. He was a mathematician, astronomer & astrologer. He's best known for his laws of planetary motion, which also provided one of the foundations for Isaac Newton's theory of universal gravitation (he is also known as an assistant to astronomer Tycho Brahe).

La principal inspiración de Johannes Kepler (1571 -1630) tiene un contenido claramente pitagórico Cuando ya estaba convencido del heliocentrismo copernicano, comenzó a preguntarse porque solamente existían seis planetas y no veinte o cien. Entonces llegó a lo que consideró su gran descubrimiento: las órbitas de los planetas eran esferas circunscriptas por los cinco poliedros del Timeo de Platón. Del mismo modo anunció que las órbitas resultan elípticas y no redondas como deberían ser.
Johannes Kepler: a German mathematician, astronomer and astrologer. A key figure in the 17th century scientific revolution, he is best known for his eponymous laws of planetary motion, codified by later astronomers, based on his works Astronomia nova, Harmonices Mundi, and Epitome of Copernican Astronomy. These works also provided one of the foundations for Isaac Newton's theory of universal gravitation.
William Lassell (1799-1880). Prominent English astronomer who discovered Neptune's moon Triton, a moon of Saturn and two moons of Uranus. He served as president of the Royal Astronomical Society and was awarded its Gold Medal. He was also elected a Fellow of the Royal Society in and won their Royal Medal in 1858.

Friedrich Wilhelm Bessel (1784-1846), was a German astronomer and mathematician, He is known for developing the unified calculation of the positions of the stars, which is still used today. Bessel was the first to determine the success of the parallax, and therefore the distance of a fixed star, 61 Cygni, providing further evidence for the heliocentric nature of the solar system. It also specifies, for the Earth, diameter, weight and value of the flattening at the poles.
Heinrich Wilhelm Matthias Olbers (1758-1840). German physician and astronomer. Best known for his discovery of the two asteroids Pallas and Vesta.

Heinrich Wilhelm Matthias Olbers (1758-1840), was a German physician and astronomer. He devised the first satisfactory method of calculating cometary orbits. He proposed that the asteroid belt, where these objects lay, was the remnants of a planet that had been destroyed. Olbers' paradox, described by him in 1823 (and then reformulated in 1826), states that the darkness of the night sky conflicts with the supposition of an infinite and eternal static universe.
Urbain Le Verrier (1811-1877) French mathematician who specialized in celestial mechanics. His calculations on the disturbance to the orbit of Uranus led to the discovery of Neptune. (Portrait by Felix Henri Giacomotti) Mona Evans, "Uranus and Neptune - Twin Planets" www.bellaonline.c...
“A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet. One of the great revelations of the age of space exploration is the image of the earth finite and lonely, somehow vulnerable, bearing the entire human species through the oceans of space and time.” — Carl Sagan
