The north star is 4000 times brighter than our sun. The light we see when we look at the north star was generated in the year 1587, and it has been traveling through space for 434 years to reach us.โ€ฆ
Beer bottles are brown as it blocks out the sun's rays and helps preserve the taste. A shortage of brown glass after the Second World War meant higher quality beer makers chose green to distinguish themselves from the companies using clear glass.โ€ฆ
Mesopotamians figured out that the Earth orbited the sun about 1,700 years before Copernicus and Newton. They also figured out that the moon causes the tides and that the Earth rotates around its axis.โ€ฆ
There is a house in New Orleans, they call it the Rising Sun, but itโ€™s not a brothel as singer Eric Burdon once described it. It's a bed and breakfast run by a Louisianan couple who love the legend and have collected over 40 versions of the Animals' song. Their B&B features ample brothelabilia.โ€ฆ

The closest star to our sun, Proxima Centauri, is at 4.25 light years away. If the most distant spacecraft Voyager 1 travels to Proxima Centauri at its current speed of 17.3 km/s, it would take over 73,000 years to arrive.โ€ฆ
Polar bears have a black skin with a transparent fur to absorb the sun's heat. They appear white because the air spaces of each hair scatters the light in all directions. polarbearsinternational.oโ€ฆ

Babylonians were using a rudimentary form of calculus to calculate Jupiterโ€™s displacement each day along the ecliptic, the path that the sun appears to trace through the stars. Historians had thought such techniques did not emerge until more than 1400 years later, in 14th century Europe.โ€ฆ

Today I learned of Xeroderma pigmentosum (XP), a rare genetic condition that makes the sunโ€™s rays lethal. Up to one in 370 Indians suffers from a genetic condition which causes skin to burn and take on a blistering, scaly appearance. With exposure to the sun, XP damages the cornea leading to blindness.โ€ฆ
The Antikythera Shipwreck of the First Century BCE, discovered by Greek sponge divers, yielded artifacts including art, jewelry, a statue of Herakles, coins, but most importantly the Antikythera Mechanism, interlocking gears that computed the movements of the sun, the moon, and eclipse datesโ€ฆ
From 1979 to 1999, Pluto was the 8th โ€œplanetโ€ from the Sun. In 206 years, it will once again cross inside of Neptuneโ€™s orbit and become 8th. This behavior is part of the reason for Plutoโ€™s demotion as a planet.โ€ฆ
At age 24, George Ellery Hale revolutionized solar observations with his invention of the spectroheliograph, making it possible to photograph the sun's prominences in full daylight. A spectroheliograph can tune-in to gases such as hydrogen and calcium, and photograph specific solar details spaceweatherlivinghistoryโ€ฆ

Sagittarius A* - the supermassive black hole at the center of the Milky Way - has a mass 4 million times that of our Sun, but a diameter only 31 times the Sun's. It is so dense that it could fit in the space between the Earth and the Sun, but can attract things 50k light years away.โ€ฆ
GRB 080319B, a gamma-ray burst that set a new record for the farthest object that was observable with the naked eye. If viewed from 1 AU away, it would have had a peak apparent magnitude of โˆ’67.57 (21 quadrillion times brighter than the Sun seen from Earthโ€ฆ
After WW2, the Allies discovered meticulous plans for a Sun Gun by the Nazis. Planned by renowned Nazi Scientist Hermann Oberth, it was a .62 mile mirror attached to a space station to burn cities and evaporate oceans estimated to take 15 years to build. He later joined NASA.โ€ฆ
Today I learned of the Coronal Heating Problem. For some reason, the Corona - the open space surrounding the Sun and extending millions of kilometers into space - is much hotter than the surface of the Sun itself. And not by a little. The corona is MILLIONS of degrees Kelvin hotter, and we don't know why.โ€ฆ
