An artistic illustration of what it would look like from Earth during the Milky way-Andromeda galaxy collision event. The Andromeda Galaxy is approximately 2.5 million light years away from our galaxy, the Milky Way galaxy, and they are moving towards each other at approximately 300 kilometers (186 miles) per second.
The Milky Way as seen from Sajama National Park in Bolivia, an area with little light pollution. As viewed from Earth, the visible region of the Milky Way's galactic plane occupies an area of the sky that includes 30 constellations. [e] The Galactic Center lies in the direction of Sagittarius, where the Milky Way is brightest.
The first close passage of the Andromeda Galaxy and the Milky Way. [95] 2 billion High estimate until the Earth's oceans evaporate if the atmospheric pressure were to decrease via the nitrogen cycle. [96] 2.55 billion The Sun will have reached a maximum surface temperature of 5,820 K (5,550 °C; 10,020 °F).
The supermassive black hole at the center of our Milky Way galaxy is associated with wanton destruction, but a recent discovery throws that assumption into question. A team of international ...
While Earth is located about 26,000 light-years from what's known as the galactic center, the outer portions of the Milky Way are even further, at about 58,000 light-years from our galaxy's ...
Previously, astronomers have spotted the supermassive black hole at the center of the Milky Way giving a swift kick to a star, which will leave the galaxy for good in about 100 million years. A ...
There is no known way to create the space-distorting wave this concept needs to work, but the metrics of the equations comply with relativity and the limit of light speed. [ 9 ] A wormhole is a hypothetical tunnel through space-time that would allow instantaneous intergalactic travel to the most distant galaxies even billions of light years away.
The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the cooling rate of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity.
