Astronomers Discover a Rare Galaxy located at 9.3 Billion Light Years Away

A team of international astronomers led by scientists at IUCAA (Inter University for Astronomy and Astrophysics) discovered a galaxy which is located 9.8 billion years located away from earth.

The Astronomers were from Switzerland, India, Japan, Netherlands and Us used Astrosat satellite which India’s first dedicated multi-wavelength telescope and it was launched on PSLV-XL on 28th September, and it was used to detect light emanating from the galaxy which is a part of AUDFs01- galaxies.

The discovery was led by Professor Dr.Kanak Saha and associate professor at IUCAA and the paper has been published on Monday by Nature Astronomy.

While the galaxy was discovered back in 2016 and it the observation lasted 28 hours but it took almost 2 years to diligently analyze and study the complete data of the Galaxy they had detected.

In a statement issued by IUCAA explained that after the Big Bang, the Universe was a hot soup of particles (i.e., protons, neutrons, and electrons). As the universe began to cool, the protons and neutrons began combining into ionized atoms of hydrogen (and eventually some helium). These ionized atoms of hydrogen and helium attracted electrons, turning them into neutral atoms — which allowed light to travel freely for the primary time, since this light was no longer scattering off free electrons. The universe was no longer opaque. But there were no stars, and no galaxies, and therefore the Universe was dark.

A while after this, maybe a few hundred million years after the Big Bang, the dark ages ended when the first stars and galaxies formed and the energy pouring out from them ionized the hydrogen and helium, splitting the atoms back again in protons and electrons, — this is the epoch of reionization.

This Is How Do Ocean Waves Form And Why They Are Continuous?

Normal ocean waves result from the frictional drag of wind on the surface of the water. The waves you observe at a given beach may originate thousands of kilometres away,whereas tsunami waves are caused by displacement of the crust caused by an earthquake. Waves have a crest and a trough, the distance between crests being known as the wavelength. Waves travel in groups called a wave train. Waves are not all moving at the same speed. When one wave catches up to another you can end up with an even higher wave. This is called constructive interference. Ocean waves can travel hundreds of kilometres before they reach the land. The distance of water over which the wind has blown is called the fetch. A long fetch will result in big waves and big waves carry with them a tremendous amount of energy. Storms create destructive waves thus a lot of erosion takes place during storms,Even on calm days it is possible to get big waves as these ones have been generated in a storm somewhere else som...

Dr. Br Ambedkar

The day 6th December marks the death anniversary of Dr. Ambedkar known as the Chief Architect of Indian Constitution, Jurist, and a Buddhist revivalist, and every year this day is being celebrated as Mahaparinirvana diwas. The word Mahaparinivana diwas refers to ultimate Nirvana (meaning eternal happiness and peace) after death, regarded as one of the major principles of Buddhism. As he owned the status of a Buddhist leader we cite his death anniversary as Mahaparinirvana Diwas. He was born in 1891 in an Untouchable cast known as Mahar, and though from that time throughout his life, since childhood, he fought against the untouchability. In the year 1912, Ambedkar received his first degree in political science and economics from Bombay University after which he got a job in Baroda and then he decided to move to the US. Afterward, in 1916 he received a doctorate from Columbia University and according to him, it was the first place where he experienced social equality. He ...
