New Space Telescope Releases Its First Images
<p>One of Euclid’s main mission objectives is to create a 3D map of the Universe, with time being the third dimension. When we look at distant objects in space, we are not just looking far away, but back in time. This is because despite seeming to appear instantaneously, even light has a limit to how fast it can travel.</p>
<p>Shortly after the Big Bang, matter began rapidly expanding outwards, forming the stars, galaxies, and planets we know today. The Universe is still expanding, meaning that most objects in space continue to travel away from us. The further away an object is, the further its light has to travel. Thus we are always seeing the starlight of the past, with the most distant objects also being the oldest.</p>
