What can a telescope see? It's more "explosive" than you think

From the first time human ancestors looked up at the starry sky, to people learning to use stars to determine direction, to observing solar eclipses through pinhole imaging, to grinding lenses to view the stars, finally, thousands of people worked together with the help of science to not only build so many large-scale and spectacular telescopes on the ground, but also sent powerful telescopes into space far away from the earth.

Human beings have never left the starry sky, and they have never stopped to "see further". As the scale of observation becomes larger and larger, we have discovered new celestial bodies and observed unprecedented physical phenomena. These have allowed humans to get closer to the mystery of the origin of the universe and to constantly think about their own existence. Today, let us "pick up the telescope" and look into the depths of the universe.
