This close-up view shows the galaxy MACS0647-JD, the farthest object yet known, as it appears through a gravitational lens imaged by the Hubble Space Telescope. The galaxy is 13.3 billion light-years from Earth and formed 420 million years after the Big Bang.
Another way of understanding the vastness of interstellar distances is by scaling: one of the closest stars to the Sun, Alpha Centauri A (a Sun-like star), can be pictured by scaling down the EarthâSun distance to one meter (~3.3 ft).
