Forget the normative ten kilometer(s) of travel during various prisons. Now let’s look even bigger.

A ride in the farthest galaxy

A grand tour into the farthest galaxy, 13.4 billion light years away, anyone? The scientific podcast of Sixim Science, for its 54th episode science and the future and 20 minutes, takes you on a journey to the limits of the universe. on the microphone, Fabrice Nicot, journalist at science and the future, Astronomy and physics expert answers questions from Romain Golloumes 20 minutes.

A journey made possible thanks to Hubble

Welcome to the farthest galaxy ever discovered, which finally reveals its shape! A trip was apparently made possible thanks to the famous space telescope Hubble. So, what was just a blurry function in 2014 is actually called “GN-z11” and opens the door to the far reaches of the universe. Welcome to the giant clouds of gas, the clouds of the Milky Way never seen before.

But Hubble isn’t the only instrument available for this type of exploration. JWST (James Webb Space.)The telescope), which should be launched in the fall, is also an instrument that experts are eagerly awaiting. “We go from 2.4m mirror to 6.5m with Hubble”, gave this information to astronomer Fabrice Nicot Daniel Scheerer of the University of Geneva (Switzerland). i.e., a surface area seven times as large and a gain in scale making it possible to detect hundreds of types of galaxies GN-Z11’s”, the scientist predicts. Undoubtedly a guaranteed ticket to other space voyages to come.
