There are a lot of discoveries happening all around the world regularly. And now also NASA has come up with a new discovery. The astronomers have found out that there are possibilities of some ingredients to be missing in our cosmic recipe in the behaviour of dark matter.
They have come up with a clear picture of how the dark matter actually is in the cluster and how the theoretical model suggests that it should be. As we all know from previous discoveries that dark matters do not absorb, emit or reflect light. We know about its existence only because of its gravitational pull that is experienced by all the visible matters present in the space. Thus, we can say that in a way dark matter is elusive like Cheshire Cat from Alice in Wonderland.
The only evidence that it exists is its gravity, we cannot see it for real like we can’t see Cheshire cat in the movie. Astronomers use the method of gravitational lensing for measuring the distorted space by the dark matter’s gravity so that it can be detected.
Scientists have found out that concentration of dark matter in small scale clusters emit gravitational lensing effect. And these produced effects are much stronger than it was predicted by them. These reports are a result of several experiments and observations made by the astronomers and researchers of NASA’s Hubble Space Telescope. Along with this extraordinary telescope the observations were also made by European Southern Observatory’s Very Large Telescope (VLT) in Chile.
A number of experiments are being done by the scientists regularly and thus, a lot of discoveries are made. So, stay tuned for more such interesting facts.
