The Hubble Space Telescope (HST) was launched into orbit in 1990.
It has since become the most powerful space observatory ever built. Its main purpose is to study the universe.
Hubble is a joint project between NASA and the European Space Agency. It consists of two parts: the primary mirror and the instruments.
The primary mirror is composed of 18 segments, each weighing over 2 tons. The instrumentation part contains four scientific instruments.

Where Is The Hubble Space Telescope Right Now?
The Hubble Space Telescope is an orbiting telescope located in space. It was launched into orbit by NASA in 1990.
It orbits around the earth every 97 minutes. It is inclined 28.5 degrees to Earth’s equator.
The Hubble Space Telescope’s position all depends on where you are in the world and where it is in its orbit.
How Large Is The Hubble Space Telescope In Size?
The Hubble Space Telescope was designed to be as big as an elephant. It weighs more than two elephants.
A large mirror makes up most of the telescope. This mirror is made out of glass. Glass is very fragile.
The telescope needs to be protected from dust and other things that might scratch or damage the mirror.
The telescope also needs to be kept clean.
Fortunately, the repair of the Hubble Telescope was completed in December 1993 and a space shuttle had been used to fix it.
How Far Can the Hubble Telescope See?
The farthest galaxy ever observed by the HUBBLE telescope is the GN-Z11 galaxy, about 13,400,000,000 light-years away.
This galaxy is about 32,000,000,000 light-years away from earth.
What Discoveries Has The Hubble Telescope Made?
Throughout its mission over the last 30+ years, the Hubble Space Telescope has made over 1.4 million observations with 16,000 studies based on this data.
The telescope has helped us understand the causes of gamma-ray bursts, how planetary collisions affect the expansion of the universe, and how nearly every major galactic cluster is anchored by a black hole at its center.
The telescope has also improved our knowledge of the Universe’s age, the atmosphere of exoplanets, and how galaxies evolve.
Solar System Discoveries
A new discovery about Jupiter’s moon Ganymede reveals that there is an underground sea of water.
Scientists use Hubble to determine this by studying how Jupiter’s magnetic field interacts with Ganymede’s.
This helps them understand more about Jupiter’s atmosphere and magnetosphere.
From June to August 2015, NASA launched a spacecraft called Hubble into space. Hubble was used to searching for Kuiper belt objects.
A Kuiper belt object is an icy body orbiting far beyond Neptune.
When searching for them, Hubble was used to looking for Kuiper belt object targets.
These targets were chosen because they could be found by using ground telescopes but not by looking up at the sky.
In this case, the Kuiper belt extended mission team wanted to use Hubble to look for Kuiper belt objects.
After looking for these objects, Hubble discovered 5 new Kuiper belt objects, including the eventual Kuiper belt extended missions target, 486958 arrokoth.
Ozone is a gas that protects us from harmful UV rays. Astronomers use it to protect telescopes from damaging light.
In this case, the telescope detects ozone in our atmosphere.
Hubble’s elevated perspective allows it to peer farther away from Earth than any other telescope.
This gives us a view of how things looked millions of years ago. We see the Andromeda Galaxy as it was millions of years ago.
In 1995, astronomers used the Hubble Space Telescope to take pictures of a part of the universe that was previously thought to be empty.
This picture showed thousands of galaxies, some of them as young as 10 million years old.
Hubble helped astronomers measure how much time had passed after the big bang.
By measuring a special type of pulsating star called a Cepheid variable, scientists narrowed down the age of the Universe from its previous range of 10 to 20 billion years to a more precise thirteen point seven billion years.
The Hubble telescope has been used to discover many things about our Universe.
Dark Matter and Dark Energy are two mysteries that the Hubble telescope has solved. Black Holes are found everywhere in the Universe.
Hubble’s images show us the universe in many different ways.
We see how stars evolve over time, we learn about distant galaxies, and we discover new planets around other stars.
Hubble is used to observing objects in our Solar System.
Images taken of Jupiter, Saturn, and Pluto have provided insights into these objects that cannot be matched by other methods.
Four of Pluto’s moons were discovered using Hubble data, for example.
Scientists use images taken by the Hubble Space Telescope to study the atmospheres of planets and moons.
Images show the effects of comets crashing into Jupiter in 1994.
Water plumes erupting from the moon of Jupiter were first observed in 2014. A second plume was detected in 2016.
Hubble has been observing since 1990 and has made many amazing discoveries.
In 2001, Hubble detected a very faint object near the center of our Milky Way Galaxy.
This object was named Sagittarius A* (pronounced “Sagittarius A-star”).
Scientists believe this object is a supermassive black hole that is 4 million light-years away.
Likewise, 2013 was a year full of discoveries. Scientists observed the spectacular Comet ISON breaking apart before it reached the sun.
An explosion occurred on a distant star. A new moon of Neptune was discovered.
And astronomers found out more about the history of our galaxy by looking at 400 different galaxies.
Who Was The Hubble Space Telescope Named After?
The Hubble Space Telescope is a space telescope launched by NASA in 1990.
It was named after Edwin P. Hubble, an astronomer who discovered many more galaxies than any other person before him.
He is also credited as the man who proved the universe is expanding.
It is located in orbit around Earth. It is used to study distant objects in the universe. It is also used to help us understand how our galaxy formed.
Servicing Missions And New Instruments
Hubble was designed to be serviced regularly. This means that there are many parts that need to be replaced periodically.
There are also some instruments that need to be upgraded or repaired.
Servicing missions are required to service the telescope. These missions are scheduled every few years.
Showing Its Age
Hubble was launched in 1990 as the first space telescope ever built. It is still operating today.
In the summer of 2020, the telescope experienced problems with its main computer system. The team switched to back up systems.
A few months later, in the fall of 2020, a problem occurred with the telescope’s internal messaging system.
This caused all five scientific instruments to enter safe mode. The team got all the instruments back up and running again.
Hubble is still working fine after this glitch.
Hubble’s systems will last until 2025. After that, engineers predict that Hubble will continue to work as long as possible.
Engineers also predict that the James Webb Telescope will last until 2028. Webb will be launched in 2018.
Astronomers are excited about using Webb and Hubble together.
Webb will view the Universe in infrared light while Hubble is strongest in optical wavelengths, so studying the Universe with both observatories will give us a wealth of insight and knowledge.
The Hubble Space Telescope was launched into orbit on April 24, 1990. Since then, it has been used to capture amazing views of the cosmos.
In fact, there were times when the telescope had problems. But, after each problem, the team worked hard to fix it.
And now, the Hubble Space Telescope has surpassed a major milestone. The telescope has been working flawlessly since January 2018.
The HST is still going strong after 25 years. In fact, it’s now one of the best telescopes in the world.
But there was worry that its lifespan could end sooner than expected.
Prior to 2020, there were worries that the telescope’s use would come to an end in 2020.
However, thankfully, processes were put into place, and the HST is still in use.
Allowing earthlings to continue to see new star systems born into the galaxy for years to come.
