Falklands War Begins - April 2 @ 01:00
On this day in 1982, the Falklands War began, pitting Great Britain against Argentina for control of the Islands. Argentina surrendered 74 days later.

Battle of Vimy Ridge - April 9 @ 01:00

Trans-Canada Air Lines Formed - April 10 @ 01:00
On this day, back in 1937 (now 88 years ago), Trans-Canada Air Lines was formed. It eventually went on to be renamed "Air Canada" in 1965, and to swallow Canadian Airlines International (formerly Canada Pacific Airlines, or CP Air), which itself had absorbed WardAir a few years before (1989) in 2001.
Yuri Gagarin in Orbit - April 12 @ 01:00
On this day in 1961, Soviet Cosmonaut Yuri Gagarin became the first human to orbit the earth, aboard Vostok 1. Following the flight, he was made a Hero of the Soviet Union. From that point on a national treasure, he was forbidden further space flights. He later died, in 1968, in a plane crash. Since the year 2000, an annual event, Yuri's Night, celebrates milestones in space exploration. This date was declared the International Day of Human Space Flight by the UN.
First Space Shuttle Launch - April 12 @ 01:00
On this day in 1981, Space Shuttle Columbia was launched from Cape Canaveral, Florida, on an orbital flight commanded by John Young, a Project Apollo veteran, and Bob Crippen. Columbia went on to make many more flights before breaking up during re-entry in 2003.
Full Moon - April 12 @ 11:22
The Moon is most-opposite the Sun in the sky, rising as the sun sets.
1906 San Francisco Earthquake - April 18 @ 01:00
Northern California experienced a massive (magnitude 7.9) earthquake, on this day in 1906, which ruptured gas lines, causing widespread fires.
Last Quarter - April 20 @ 12:35
A waning half-Moon is near the meridian (halfway across the sky) as the Sun rises.
Second Battle of Ypres - April 22 @ 01:00
In this World War I battle, begun on this day in 1915, Canadians were in the forefront. Over the course of the battle, which lasted until May 25, Canadians were subject to violent bombardment and poison-gas attacks, but held the line and eventually emerged victorious.
Earth Day - April 22 @ 01:00
The first Earth Day was celebrated back in 1970.
HST Launched - April 24 @ 01:00
On this day 35 years ago (1990), the Hubble Space Telescope was launched. The first large space telescope, the Hubble initially had severe focusing problems; but a later servicing mission repaired Hubble's focus with a special package of corrective lenses. The Hubble went on to make over 30 years of discoveries as the premiere optical space telescope, before being supplanted by the James Webb Space Telescope, but remains in service, with investigations into extending its lifespan by up to 20 years.
Chernobyl Disaster - April 26 @ 01:00
On this day in 1986, the No. 4 reactor of the Chernobyle Nuclear Power Plant exploded, releasing radiation in into the environment. A years-long effort to stabilize the reactor followed, and today it is enclosed in a giant metal 'sarcophagus'. It has repeatedly come into danger during the Russo-Ukraine war.
New Moon - April 27 @ 06:31
The Moon is nearest the Sun in the sky and cannot be seen from the ground.
