William Wilson Morgan (3 Jan 1906 - 21 Jun 1994)

He was an American astronomer who provided the first evidence that the Milky Way Galaxy has spiral arms. His research was devoted to the morphology, the classification of objects by their form and structure. He also invented the UBV System of magnitudes and colors.

Charles Augustus Young (15 Dec 1834 - 3 Jan 1908)

He was an American astronomer who made the first observations of the flash spectrum of the Sun, discovered the reversing layer of the solar atmosphere, and proved the gaseous nature of the Sun’s Corona. During the eclipse in Spain in 1870, he saw the lines of the solar spectrum all become bright for perhaps a second and a half and then he announced the “reversing layer”.

First Artificial Nuclear-Transmutation of Elements

On this day, Ernest Rutherford bombarded nitrogen atoms with alpha particles emitted by radioactive materials and successfully transmuted nitrogen atoms into oxygen. He succeeded in splitting the atom.

Oklahoma Meteorite


In 1970, this Meteorite was visible over a large area of the US Midwest. It was the first Meteorite to be detected that fell, after 1964. The first retrieval enabled examination of radioactivity produced by the meteorite when exposed to the Cosmic Rays.

Edward Walter Maunder (12 Apr 1851 - 21 Mar 1928)

He was an English astronomer who first started the British Civil Services Commission examination for the post of photographic and spectroscopic assistant at the Royal Observatory, Greenwich. He worked at the observatory for the next forty years measuring the sunspots and checking historic records. He found a lack of reports on sunspots from 1645 to 1715. Instead of questioning this, he started researching and found that there are indeed decades-long times when the sun has very few sunspots. Now we call these periods as Maunder minima.

Ferdinand von Lindemann (12 Apr 1852 - 6 Mar 1939)

He was a German mathematician who proved that π is not a solution to any algebraic equation with a rational coefficient. This explained the insoluble natural or classical Greek mathematical problem of constructing a square with the same area as a given circle using a ruler and compasses alone. He discussed Hermite’s methods that he used to prove that ‘e’ is transcendental. He extended Hermite’s results in 1882 to show that π was also transcendental.

Charles Messier (26 Jun 1730 - 12 Apr 1817)

He was a French astronomer who first compiled a systematic catalog of “M objects” and discovered 15 comets. His catalog contained nebulae, 103-star clusters, and galaxies. He concluded the alphanumeric names for objects like M1, M2, etc.

Geoffrey F. Chew (5 Jun 1924 - 12 Apr 2019)

He was an American physicist who led the group of S-matrix theorists researching the strong interaction and the bootstrap principle. He was a graduate student of Enrico Fermi. His group calculated the interactions of bound-states without assuming that there is a point-particle field theory underneath.

Igor Tamm (8 Jul 1895 - 12 Apr 1971)

He was a Soviet physicist who shared the Noble Prize with Pavel A  Cherenkov, and Ilya M. Frank for physics for his works in explaining Cherenkov radiation. He developed the theoretical interpretation of the Cherenkov effect which states that the radiation of electrons moves faster than the speed of light through matter. He also developed a method for studying the interaction of nuclear particles and contributed towards the methods for the control of thermonuclear reactions.

First Man To Orbit The Earth

On this day, Yuri Gagarin became the first man to orbit the Earth in 1961. The control of the spacecraft was locked to prevent him from taking control of the ship. It had a radio, television, and life-supporting equipment. He ejected and made a planned descent landing with his parachute but the Soviet Union denied this to save its reputation. After 7 years, he died in a plane crash.

The First Yo-Yo Toy In Space

The first yo-yo toy was taken into space in the Space Shuttle Discovery mission 51-D in 1985. With this yellow plastic Duncan Imperial yo-yo, other toys were exhibited during a time in orbit. Astronauts did the tricks with toys but the yo-yo sleeper trick couldn’t work without normal gravity. While spinning, the gyroscope showed exceptional stability. The flywheel slowed without normal gravity.

Space Shuttle Columbia Was Launched

Columbia, the American Space Shuttle was launched into space in 1981. John W. Young was the mission commander.
