In approximately 300,000 years, WR 104, a triple star, is expected to explode in a supernova. It has been suggested that it may produce a gamma ray burst that could pose a threat to life on Earth should its poles be aligned 12° or lower towards Earth. However spectroscopic observations now strongly suggest that it is tilted at an angle of 30 ...
The moon will appear to move in front of the sun beginning at 2:07 p.m. on April 8 in Rochester, New York. ... 2024 solar eclipse countdown clock shows how much time to eclipse. Show comments.
Earth will interact tidally with the Sun's outer atmosphere, which would decrease Earth's orbital radius. Drag from the chromosphere of the Sun would reduce Earth's orbit. These effects will counterbalance the impact of mass loss by the Sun, and the Sun will likely engulf Earth in about 7.59 billion years from now. [17]
Langsdorf chose a clock to reflect the urgency of the problem: like a countdown, the Clock suggests that destruction will naturally occur unless someone takes action to stop it. [ 12 ] In January 2007, designer Michael Bierut , who was on the Bulletin ' s Governing Board, redesigned the Doomsday Clock to give it a more modern feel.
These explosions — billions of times brighter than the sun — destroy the star, often leaving behind a black hole. Supernovas are also a useful tool for astronomers to measure distance.

A solar storm is a disturbance on the Sun, which can emanate outward across the heliosphere, affecting the entire Solar System, including Earth and its magnetosphere, and is the cause of space weather in the short-term with long-term patterns comprising space climate.
The Sun is 1.4 million kilometers (4.643 light-seconds) wide, about 109 times wider than Earth, or four times the Lunar distance, and contains 99.86% of all Solar System mass. The Sun is a G-type main-sequence star that makes up about 99.86% of the mass of the Solar System. [26]
