If they solve this question, they could figure out how many galaxies there are in the universe.
How dark is the space? It is a question that scientists of the POT. And that they also try to solve with the data that the mission can provide them New horizons. The US agency’s space probe must be located somewhere near Pluto, studying the kuiper belt.
But many will wonder: why does NASA want to know how dark space is? They detail that, if they know the answer to this question, they could estimate the number of galaxies in the universe. There are some that are very far away and difficult to detect, but you can still detect a flash of energy.
So, knowing the amount of dark matter, they could approach the number of galaxies there are. To achieve it not only New Horizons will participate. They will also need the collaboration of the space telescope Hubble.
Calculations, measurements, Hubble and New Horizons
NASA scientists post an explanation on their website so that we can all appreciate what they are trying to say. First of all, they detail that, when we move away from the lights of the city and look towards the sky, we see that the sky is darker among the stars. So this is what they tried to do with Hubble.
Submerged in space, the look of the telescope gave a data that was believed to be correct. But that, to make it more precise, it was necessary to get out of the inner solar system. The latter with the intention of avoiding the light that our massive star radiates. That is, the Sun.
Therefore, the information that New Horizons can provide comes into consideration. Away from any type of light pollution, it is capable of registering the level of dark matter with more precision. In this way, you can have an approximate number of galaxies that exist in the universe.
