Mysteries of Universe and Cosmos

2

Though our universe is nearly 13.7 billion years old, it still holds many a secret that astronomers and astrophysicists have not been able to unravel to this day. Astrophysicists yet don’t know what causes Fermi bubbles or pulsars to pulsate or what exactly is dark matter composed of. Mentioned below are some mysteries or oddities of the universe that have kept astronomers on tenterhooks.

  1. Where is the missing part of the Universe?

Dark energy makes up 70% of the cosmos and dark matter comprises another 25% and the balance 5% is made up of routine or normal matter. Surprisingly enough 50% of this normal matter remain untraceable that has continued to baffle astrophysicists and space researchers.

The regular matter has been termed as baryonic matter and is comprised of electrons and protons. Some astronomers allege that the missing part lies in between galaxies but unfortunately have not been able to backup their proposition with concrete evidence.

  1. Dark Energy Remains Elusive

Nearly 70% of the universe is constituted of dark energy which is making the cosmos accelerate and expand at huge speeds. Irritatingly enough, this dark energy still remains nebulous as space researchers have failed to detect the same.

  1. Incredible Hotness of Sun’s Corona

The corona of the sun comprising the outer periphery of the star is staggeringly hot at 6 million degrees centigrade. Physicists have carried out studies that indicate a faint correlation between the magnetic field of the sun and the energy underneath its visible surface leading to the heating up of corona.

  1. How Are Supernovas Formed?

Exploding stars or supernovas blast off so scintillatingly that the glow from neighboring galaxies simply pale in comparison. However, astronomers haven’t been able to figure out the mechanism that causes stars to explode.

  1. What Causes Pulsars to Pulsate?   

The first pulsar (a kind of neutrino star emitting electromagnetic beams and spinning rapidly on its axis) which was traced in 1967 continues to flummox space scientists. They are completely clueless about what makes pulsars pulsate or even stop pulsating-a phenomenon that was observed in 2008.
