Top 6 most intriguing predictions concerning the future of the universe

Even though predictions about the universe's future cannot be completely accurate, knowledge from a plethora of currently existing fields (ranging from astrophysics to evolutionary biology) can be used and applied to make predictions about the far future relating to the universe, however broad or vague they may be.

Years from now	Event
10,000	The star Antares (which has a diameter roughly 700 times that of our Sun’s) will likely explode in a supernova which will probably be easily seen with the naked eye
36,000	Ross 248, a red dwarf, will pass within roughly 3 light years of Earth, becoming the closest star to the Sun for a period of time. In comparison, the closest star currently is about 4.26 light years away, known as Proxima Centauri.
50,000	The current 'warm period' (more formally known as interglacial period, that is, the time between ice ages) ends, sending the Earth into a global ice age.
100,000	Many of the constellations we see today will be rendered unrecognisable due to the proper motion of stars.
500,000	Our home planet is likely to have been struck by an asteroid roughly 1 km in diameter assuming it cannot be averted.
1,000,000	The star Betelgeuse which is easily visible in the night sky today with an apparent magnitude of  0.42, is thought to have exploded in a supernova which will easily be visible during the day.
