What if you could keep your eye on the telescope and actually see what our galaxy would look like in the distant future?
ESA scientists went there. Using Kia Early Data Release 3 (Gaya EDR3), they created an animation showing the evolution of the Milky Way over the next 1.6 million years, although the final framework is for the less confusing picture of the galaxies showing our galaxy 400,000 years from now. It allows you to see the future orbits of 40,000 stars at a distance of about 326 light years from the Sun. Although it does not account for all the stars within those boundaries, it does give an accurate view of how they travel (relative to the Sun) as they fall, fall, and move closer or further to our star.
“From the knowledge of the position of a star in the sky today, and from the distance and motion measured by Kia, we can predict where the stars will appear in the sky in the future,” ESA astronomer Anthony Brown, who led the effort using an index, told SYFY WIRE.
Cosmic spider webs actually appear when stars migrate above ions. Also the motions of distant stars appear to be short lines that do not move as fast as long ones – but they are designed in this way due to optical illusion. Do you know how something really moves farther slowly and moves farther over shorter distances, but as you get closer it seems that speed and distance increase? It’s like that. If you look closely, you may also notice that some of the star tracks that start moving faster move more slowly, or end in reverse. These stars are expected to approach the sun, but then crawl further away.
Simulation also assumes that they accelerate straight into space. In fact, stars, including our Sun, constantly change direction as they orbit the Milky Way. Rotating objects are always changing.
Looking up to 1.6 million years into the future is a fascinating type — but the measurements here should also predict the Sun’s acceleration caused by the gravitational pull of the Milky Way. This does not mean that it is only a prediction of where the sun will go. The acceleration animation of the pericenter or center of mass of the universe is really what shows how things appear in the solar system in our galaxy, not just the acceleration of the Milky Way. This is the acceleration of the pericenter (mass center) of the solar system, which is represented by the animation.
“As the solar system orbits the Milky Way, the bisector changes very slowly over time and feels the effect of various mass concentrations (such as spiral weapons, large molecular clouds, or very large dwarf galaxies orbiting the Milky Way),” said Brown. Not noticed. ”
This animation made it possible to upgrade from Kia TR2 to Kia ETR3. The ETR3 data gave Brown’s team the advantage of being able to measure the motions of the stars more accurately, because at this time, the space telescope has processed many more observations, with much time elapsed between the first and last observation. The animation above is basically like pressing the fast forward button on the galaxy. If the stars were shown to be moving at their true rate, not only would it be painful to watch, you would sit there and skeleton for 1.6 million years.
The simulation feels like watching thousands of shooting stars flying in the Milky Way, but they turn to the right side of the screen and leave a void on the left. Things look like that with respect to the movement of the sun, and it would seem that the stars are all moving in opposite directions. This is another optical illusion If you are the Sun, as you travel through the galaxy, you will notice the stars in front of you farther away as you approach them, while those behind you appear to cluster closer together. Travel.
As Kia sends more data to Earth, it not only continues to be added to this simulation, but also allows Brown and other ESA scientists to create more simulations on this nerve.
“The more data we collect, the more accurate the distances and motions will be. We will be able to create such simulations on larger volumes, different stars and different time scales,” he said. “We look forward to seeing what the solar system will look like in the long run.”
