Someday, billions of years from now, long after everyone on this Earth is gone, our Milky Way (MW) galaxy will undergo the most impactful event of its celestial existence. It will collide with ...
According to evidence found in 2015, it is the largest ever recorded. [70] A third, possible impact was also identified in 2015 to the north, on the upper Diamantina River , also believed to have been caused by an asteroid 10 km across about 300 million years ago, but further studies are needed to establish that this crustal anomaly was indeed ...
Simulated collision of two neutron stars. A stellar collision is the coming together of two stars [1] caused by stellar dynamics within a star cluster, or by the orbital decay of a binary star due to stellar mass loss or gravitational radiation, or by other mechanisms not yet well understood.
A chain of craters on Ganymede, probably caused by a similar impact event.The picture covers an area approximately 190 km (120 mi) across. Jupiter is a gas giant planet with no solid surface; the lowest atmospheric layer, the troposphere, gradually changes into the planet's inner layers. [10]
The parade of planets will be visible throughout the northern hemisphere and will peak on June 3. While there are six planets in play, we’ll only be able to view two easily with the naked eye ...
The Sun will likely expand sufficiently to overwhelm most of the inner planets (Mercury, Venus, and possibly Earth) but not the giant planets, including Jupiter and Saturn. Afterwards, the Sun will be reduced to the size of a white dwarf , and the outer planets and their moons will continue to orbit this diminutive solar remnant.

Excluding planetary engineering, by the time the two galaxies collide, the surface of the Earth will have already become far too hot for liquid water to exist, ending all terrestrial life; that is currently estimated to occur in about 0.5 to 1.5 billion years due to gradually increasing luminosity of the Sun; by the time of the collision, the ...
