Milky Way Will Appear After 400000 Years

Scientists Show How The Milky Way Will Appear After 400000 Years From Now By A Time-Lapse Image


Many experts have said that the night sky will look completely unusual after half a million years from now. However, scientists from the European Space Agency (ESA) have found how it might look like. Experts from ESA’s Gaia Space Observatory have made a 60-second time-lapse simulation of the solar system floating slowly through the Milky Way. The new simulation shows around 40000 stars, situated within 325 light-years of Earth’s sun, rush through space, leaving long tracks of light behind them. As per the experts, each tip of light reflects one real object in the Milky Way. At the same time, each trail of light shows the targeted movement of the object through the galaxy over the next 400000 years. Experts said that brighter and faster strips of light are quite closer to the solar system and dim and slow streaks are located quite far away.

Experts from ESA have said that the simulation follows a not so surprising pattern. The simulation shows that at the end of the animation, the majority of the stars have been clamped together to the right side of the screen, leaving the left side relatively empty. They have said that these stars are not being towed to the right side by any newly discovered black hole or an alien tractor beam, rather it might be due to the Sun. The Sun is moving continuously as well, which leads stars to appear clustered in the opposite direction. Scientists have said that the effect occurs due to the movement of the Sun with respect to the stars.

The third official data release (EDR3) of the Gaia satellite has been used to make this mosaic of cosmic fireflies possible. This data (EDR3) has been published on December 3. This data dump has vast details about nearly 1.8 billion outer space objects, which includes their precise position, velocity, and orbital trajectories of around 330000 stars within 325 light-years of the earth. The 40000 stars which have been shown in the simulation have been chosen randomly by experts. The Gaia satellite has been launched in 2013. Scientists aim to measure the arrangement, distances, and movements of the stars with the help of the satellite. The second data release of this satellite has been published in 2018, which has helped scientists to come up with the most accurate and detailed map of the universe for the first time. Experts from the European Space Agency have said that the third data release has found nearly 100 million new objects.
