As we already know, to study distant objects, astronomers have to use telescopes to collect data and observe. I am sure that astronomers would want to come close to their objects than seeing them through lenses. Given the current technology that we have, traveling close to distant objects is unrealistic. With that said, what if we could travel close to speed of light? Astronomers can achieve much more than they have today. However, would we want to travel at speed of light? What it feels like to travel at close to light’s speed. The above video was found on NASA Astronomy Picture of the Day website.
From NASA: First of
all, relativistic aberration would cause objects to appear to bunch up in front
you. Next, the Doppler shift would cause the colors of forward objects to shift
toward the blue, while things behind you would shift toward the red. Similarly,
the world in front of you would seem to move unusually fast, while the world
behind you would appear to slow down. Objects to the sides will appear rotated,
possibly enabling surfaces normally hidden from you to become visible. Of
course, since constant motion is relative, the same effects would occur were
you to remain stationary and the entire world advanced toward you.
