A latest picture by the Hubble Telescope shows 2 mingling galaxies in space that look stunning and rather scary at the very same time.
The two concerned galaxies with names SDSS J115331 and LEDA 2073461 looked like colliding snails but actually they were quite apart from each other.
But that doesn’t mean galaxies don’t collide at all. In fact, it’s a common occurrence in space when galaxies move towards a mutual galactic center.
When two galaxies collide their supermassive black holes at theirs respective centers also merge to make even bigger black holes.
Distance is a very important factor when it comes to gauging, interpreting, and concluding about celestial bodies in the universe.
Without a proper estimate of distance between two space objects, the calculation of their size, masses, and luminosity would be inaccurate, thus giving wrong conclusions.
