What Has Telescope Hubble Revealed About the Universe?

Some people know Telescope Hubble by the stunning pictures of space that it sends back to Earth. Others rely on this Telescope to deliver the essential information that is impossible to find in any other way. Finally, a few may have never heard about Telescope Hubble. However, the latter is soon to be changed. The Hubble Space Telescope, although rather old, is still one of the greatest inventions given to astronomy. Let’s learn more about the discoveries and findings that Telescope Hubble sent back to us to study.

What is the Hubble Space Telescope?

It took about twenty years to plan and fulfill the idea of such a telescope into a reality. NASA finally launched the Telescope on the Space Shuttle Discovery back in the 1990s. Yey, it remains some of the best inventions we have for space exploration even to this day. Even though the world now relies on modern technologies to build large and more powerful telescopes, these versions often fail in comparison. The Hubble Space Telescope often gives us better and more significant results than its younger successors. Of course, its advantageous position 340 miles above Earth’s surface plays a crucial role in its success.

Overall, due to this technology, humanity could finally learn the secrets hidden deep in space. It has become our passage into understanding the universe a little bit better. Ever since the telescope started to work, it has completed over 1.3 million observations. The only upsetting fact about Hubble is that it never keeps up with ever so growing demand for its work.

Eagle Nebula

A few years after the launch, Telescope Hubble has given the world one of the greatest images of space known to man, later named ‘pillars of creation.’ The image portrays the Eagle Nebula – the three pillars of cold gas. Those three nebulas (interstellar clouds) helped hide the newborn stars. It was the first image of such a kind. As a result, astronomers could learn a great thing about the active star-forming region. No picture from any ground-based telescope could achieve such high quality and detail.

Now, the whole world is watching them.

The Age of the Universe

The age of the universe was something astronomers had been arguing about for centuries. However, we needed good technology to bring some real facts into the discussion. Fortunately, Hubble was able to help. By looking at the most long-distance marker in the universe, we could calculate how far we are from it. Thus, scientists discovered that our universe is about 13.8 billion years old.

The Universe Expansion Rate

For many years, we believed that the universe’s expansion rate was slowing down. Well, the data analyzed from Hubble showed quite the opposite thing. The universe expansion rate was rapidly increasing over the years. The Telescope showed that the light from the distant galaxies is much fainter than was expected. Thus, it proved that they were moving further away from us at a faster speed than we had expected. The astronomers also discovered that some “dark energy” in the universe causes a faster expansion rate.

The latter discovery proved that the expansion was indeed happening at the predicted speed around the first eight billion years. However, after a while, the expansion caused the universe to ‘thin out’ and, thus, dark energy gained its dominant power.

The Density of the Universe

Ever since the Hubble was launched in 1995, it was used for making deep field pictures of space. The astronomers wanted to discover the density of the university and the evolution of new stars and galaxies. They also wanted to discover places without any stars. Well, it turned out to be an impossible mission. In the end, astronomers learned that there is no empty region anywhere in deep space. It’s all stars and galleries. It’s truly hard to wrap your head around such information at first.

Overall, Telescope Hubble revealed that the universe is more like a sand beach than, let’s say, a forest. You can try to count the trees. But you definitely can’t ever know how many sand grains are on the beach. The same is our universe. It’s just impossible to learn every region there. At least not with the technologies that we have for now. So far, we have barely scratched the surface by learning about the galaxies closest to us.

The Bottom Line

Hubble was able to answer some of the most important, long-time questions. With the launch of this telescope, humanity opened up the curtain to the universe. It’s barely enough to satisfy a small fraction of our curiosity and need to know. Yet, it’s already something. Telescope Hubble put a start to numerous research and universe exploration. However, its job is far from over. Even thirty years later, we expect great things from Hubble. After all, what are thirty years for the universe? It’s a fraction of a second.
