Tycho and others had observed the supernova of 1572. Ottavio Brenzoni's letter of 15 January 1605 to Galileo brought the 1572 supernova and the less bright nova of 1601 to Galileo's notice. Galileo observed and discussed Kepler's supernova in 1604. Since these new stars displayed no detectable diurnal parallax, Galileo concluded that they were distant stars, and, therefore, disproved the Aristotelian belief in the immutability of the heavens.
The Stravinsky family returned to Switzerland (as usual) in the fall of 1913. On 15 January 1914, a fourth child, Marie Milène (or Maria Milena), was born in Lausanne. After her delivery, Katya was discovered to have tuberculosis and was confined to the sanatorium at Leysin, high in the Alps. Igor and the family took up residence nearby.
Stravinsky's unconventional dominant seventh chord in his arrangement of the "Star-Spangled Banner" led to an incident with the Boston police on 15 January 1944, and he was warned that the authorities could impose a $100 fine upon any "re-arrangement of the national anthem in whole or in part". The police, as it turned out, were wrong. The law in question merely forbade using the national anthem "as dance music, as an exit march, or as a part of a medley of any kind", but the incident soon established itself as a myth, in which Stravinsky was supposedly arrested, held in custody for several nights, and photographed for police records.
For Slovenia, the war marked the decisive defense of its independence in regard to Yugoslavia. It was officially recognised by all European Community member states on 15 January 1992.
As the UNTAES replaced the UNCRO mission, Prevlaka peninsula, previously under UNCRO control, was put under control of United Nations Mission of Observers in Prevlaka (UNMOP). The UNMOP was established by United Nations Security Council Resolution 1038 of 15 January 1996, and terminated on 15 December 2002.
Sullenberger opened the cockpit door and gave the order to evacuate. The crew began evacuating the passengers through the four overwing window exits and into an inflatable slide/raft deployed from the front right passenger door (the front left slide failed to operate, so the manual inflation handle was pulled). A panicked passenger opened a rear door, which a flight attendant was unable to reseal. Water was also entering through a hole in the fuselage and through cargo doors that had come open, so as the water rose the attendant urged passengers to move forward by climbing over seats. One passenger was in a wheelchair. Finally, Sullenberger walked the cabin twice to confirm it was empty.
Sullenberger asked controllers for landing options in New Jersey, mentioning Teterboro Airport. Permission was given for Teterboro's Runway 1, Sullenberger initially responded "Yes", but then: "We can't do it ... We're gonna be in the Hudson". The aircraft passed less than 900 feet (270 m) above the George Washington Bridge. Sullenberger commanded over the cabin address system, "Brace for impact", and the flight attendants relayed the command to passengers. Meanwhile, air traffic controllers asked the Coast Guard to caution vessels in the Hudson and ask them to prepare to assist with the rescue.
On 15 January 2019, May's government was defeated in the House of Commons by a margin of 230 votes (202 in favour and 432 opposed) in a vote on her deal to leave the European Union. It was the largest majority against a United Kingdom government in history.
