Black Sun and Inverted Starfield
Does this strange dark ball look somehow familiar? If so, that might be because it is our Sun. In the featured image from 2012, a detailed solar view was captured originally in a very specific color of red light, then rendered in black and white, and then color inverted. Once complete, the resulting image was added to a starfield, then also color inverted. Visible in the image of the Sun are long light filaments, dark active regions, prominences peeking around the edge, and a moving carpet of hot gas. The surface of our Sun can be a busy place, in particular during Solar Maximum, the time when its surface magnetic field is wound up the most. Besides an active Sun being so picturesque, the plasma expelled can also become picturesque when it impacts the Earth's magnetosphere and creates auroras.

Zürich has a singularly violent way to welcome summer: They roast a snowman until its head explodes. At the spring holiday Sechseläuten, traditionally celebrated on the third Monday in April, residents build an effigy of winter in the shape of a giant snowman known as the Böögg, pack it with explosives, and set it afire.
The shortest time on record is 5 minutes 7 seconds, in 1974. The longest, just last year, is 43 minutes 34 seconds.

February 19th 1942: Japanese internment begins
On this day in 1942, US President Franklin D. Roosevelt signed executive order 9066 which allowed the military to relocate Japanese-Americans to internment camps. A climate of paranoia descended on the US following the attack on the naval base at Pearl Harbor by the Empire of Japan, which prompted the US to join the Second World War. Americans of Japanese ancestry became targets for persecution, as there were fears that they would collude with Japan and pose a national security threat. This came to a head with FDR’s executive order, which led to 120,000 Japanese-Americans being rounded up and held in camps. The constitutionality of the controversial measure was upheld by the Supreme Court in Korematsu v. United States (1944). Interned Americans suffered great material and personal hardship, with most people losing their property and some losing their lives to illness or the violence of camp sentries. The victims of internment and their families eventually received an official government apology in 1988 and reparations began in the 1990s. This dark episode of American history is often forgotten in the narrative of US involvement in the Second World War, but Japanese internment poses a stark reminder of the dangers of paranoia and scapegoating.

February 18th 1564: Michelangelo dies
On this day in 1564, the Italian Renaissance artist Michelangelo died in Rome aged eighty-eight. He was born Michelangelo di Lodovico Buonarroti Simoni in 1475, and at a young age was apprenticed to a notable painter in Florence. He ingratiated himself with the prominent Florentine Medici family, known for their support of the arts, eventually living in the household of patriarch Lorenzo de’ Medici. Michelangelo then traveled throughout Italy, living in Bologna and Rome, all the while perfecting his sculpture work. His ‘Pietà’ in 1497 made him a well-known artist, and when back in Florence in the first years of the sixteenth century he produced his masterpiece - ‘David’. Between 1508 and 1512 Michelangelo worked on painting the ceiling of the Sistine Chapel in the Vatican, which catapulted him to fame as one of Italy’s most renowned artists. In his later years he focused more on architecture, designing buildings and facades in Florence and Rome. After an illustrious career spanning decades, Michelangelo died in 1564, with his status as one of history’s most famous artists exemplified in his sculptures and paintings.

February 17th 1600: Giordano Bruno executed
On this day in 1600, the Italian friar, astronomer and philosopher Giordano Bruno was burned at the stake for heresy. Bruno’s ideas were controversial for his day, but are now hailed as precursory to modern scientific understanding. Bruno proposed the concept of an infinite universe populated by other intelligent life and rejected traditional geocentric astronomy. He agreed with Copernicus that the planets revolve around the Sun, but expanded on this by suggesting that the Sun is just another star. For these unorthodox views, which challenged traditional Christian ideas about the universe, Bruno was found guilty of heresy by the Roman Inquisition and burned at the stake. For his refusal to renounce his beliefs, Giordano Bruno is often remembered as a martyr for free thought.
