There is a quote from the American astronomer Edwin Hubble that said that “equipped with his five senses, man explores the universe around him and calls that adventure science”, this is what the researcher said, but our senses are limited so we need instruments, with our eyes or rather someone with good eyesight and in a very dark and moonless sky, you can see about 3000 stars.
The most distant cosmic object visible to the naked eye is the Andromeda galaxy, if one day at a time, remember that the photons that have left the Andromeda stars have taken 2 and a half million years to reach your eyes, your eyes They see it because particles from those stars in that galaxy, those photons have reached you, can you imagine that one day we could analyze in detail each of those photons, which are particles that have come from that star or those that we can capture from a exoplanet, exoplanets do not emit light but the light that they bounce back from their star is altered by the gases and elements that are on that planet.
In 2016, a team of Polish researchers managed to create for the first time in history the hologram of an individual particle of light, a photon, and it is the image shown above, it is a milestone, it is a curious milestone, it is not the real image of the photon, it is its hologram, but it is very important to continue advancing on this path and develop technologies that need to understand what real shape the photon has, what it is like, because it is very important not only for astronomy, I suppose it could have incredible usefulness in astronomy but it also has an incredible utility in the field of telecommunications and the development of quantum computers.
