The idea of life on Europa, one of Jupiter's moons, gained significant attention in the 1970s following the Voyager spacecraft missions. These missions revealed that Europa has a smooth, icy surface, which suggested the possibility of a subsurface ocean beneath the ice. The concept was further popularized in the late 1990s and early 2000s as more evidence emerged, including the detection of a magnetic field around Europa, indicating the presence of a salty ocean that could potentially harbor life.
The German geologist Alfred Wegener first put forward the idea in 1912, but it did not become widely accepted until the 1950s.
Nicolaus Copernicus put forward a heliocentric theory.
In many (but not all) countries the clocks are moved one hour forward in spring and put back an hour in the fall. This was introduced during the Second World War and done to match working hours better with the hours of sunlight.
Galileo was not kicked out of his country because of his beliefs. He was put on trial by the Catholic Church for promoting the idea that the Earth revolves around the Sun, which was contrary to Church teachings at the time. He was ultimately found guilty of heresy and placed under house arrest for the rest of his life.
Whether to keep a dying person on life support is a personal or family decision. If the person is suffering it might not be fair to keep them on life support.
The idea of life on Europa, one of Jupiter's moons, was first proposed in the late 1970s, particularly after the Voyager missions revealed its icy surface. Scientists speculated that beneath this ice, a subsurface ocean could exist, potentially harboring conditions suitable for life. This hypothesis gained further traction with subsequent observations and studies, particularly in the 1990s and 2000s, as more evidence suggested the presence of liquid water beneath the moon's surface.
