Hubble discovers 250 new galaxies

On April 24, 1990, NASA released its space telescope, Hubble, with the hopes of discovering large extents of outer space. Twenty-five years later, Hubble is still out and functioning .

The Hubble telescope just recently took sharp images of 250 ancient dwarf galaxies, which are spattered tiny galaxies containing billions of stars. It is an astounding new discovery that has left scientists at NASA in a state of awe at the mysteries of our universe.

What really sparked the attention of researchers was the fact that the 250 galaxies were formed in the early stages of the universe’s expansion, about 600 to 900 million years after the Big Bang.

Relative to the lifespan of our universe, 900 million years is not a lot! This means that these newly-found galaxies are as old as time. This is why, according to astronomer John Richard, these were the faintest galaxies to be detected by Hubble and are “fainter than any other yet uncovered in the deepest Hubble observations”.

On another note, the team at NASA noticed that the light emitted by these ancient galaxies might have played a central role in an early mysterious period of the Universe’s history known as reionization, which basically refers to the clearing of the Universe from the fog which cloaked it with hydrogen gas.

Thus, thanks to the Hubble telescope, an unforgettable scientific breakthrough was made, and now the task of learning about the universe has become smoother and simpler.

One may ask what makes the Hubble telescope any different than the average telescope. Well, for starters, the Hubble hovers and orbits above the Earth’s atmosphere, providing a clearer view of the universe along with its infinite space.

Hubble received its name from the American astronomer, Edwin Hubble, who has contributed greatly to show that the universe is expanding and that our Milky Way is only one of many galaxies that exist in an ever-growing universe.

It is worthy to note that the Hubble telescope has been flawlessly providing the world with clear, high-quality images of our universe for decades.

Around 150 gigabytes of data is sent weekly to Earth, which is equivalent to about 45 HD-quality movies.

Hubble’s great discoveries continue to leave us flabbergasted and pondering the origins of the universe, but then again, do we really want to spoil such a huge mystery?
