The Many Faces of the Hubble
The Hubble Space Telescope, launched in 1990, has been an essential tool in helping scientists understand the universe beyond Earth. Download
The telescope has helped us discover many wonders of the cosmos, including details about stars and planets outside our
solar system. Here’s a brief look at some of the most intriguing Hubble discoveries to date Download
The Hubble Space Telescope has been one of the most important tools in helping us understand our place in the universe. It was
launched in 1990 and has been responsible for some of the most iconic images and
discoveries in astronomy. Here are just a few examples of how the Hubble telescope has helped us explore the universe.
The Hubble Deep Field, taken over 10 days, revealed about 10,000 galaxies with only about 200 being previously known. At its
completion in 2004, this had provided the most detailed information ever obtained on deep space objects from an orbiting observatory. Download
Another significant achievement was the capture of spiral to something new which showed how two colliding galaxies created a new form of galaxy called NGC 4302 also
known as Pandora’s Galaxy because it is displaying dramatic changes as a result of intense star formation and activity near its center.
Hubble has captured remarkable details of individual stars like never before seen through a spectrograph that splits light into its rainbow colors.
20 Years of Discovery
On April 24, 1990, the Hubble Space Telescope was launched into low Earth orbit. Since then, it has captured some of the most incredible images of our universe.
Not only has it helped us better understand our place in the cosmos, but it has also inspired a new generation of astronomers and space enthusiasts.
Here are just a few of its many contributions to science over the past 20 years. * In 1996, the Hubble photographed six newly discovered Kuiper Belt Objects.
* In 1997, they revealed that Neptune had rings (more than 150 years after their discovery by William Lassell).
* In 1998, they found that Pluto is far smaller than once thought.
* In 2000, they took what was likely the best photo ever taken of Saturn.
* In 2004, they revealed an unexpectedly bright comet that is thought to be so old that it originated at time when there were no humans on Earth yet!
Changes Over Time
The Hubble telescope has been in operation for over two decades now, and in that time it has changed the way we view the universe. For one,
it has allowed us to see distant galaxies in unprecedented detail, giving us a better understanding of how they work.
Additionally, the telescope has helped us to study dark matter and dark energy, two of the most mysterious components of our universe. In recent years,
the telescope has also been used to study exoplanets, or planets outside our solar system.
By observing these planets, we can learn more about how our own solar system came to be.
The Hubble telescope truly is a remarkable tool that has helped us to unlock some of the universe’s most secrets.
But as with any great invention, there are tradeoffs. Namely, the lifespan of Hubble is limited by its hardware;
after all, no instrument lasts forever. As such, NASA is looking into options for replacing the venerable space telescope.
These options include constructing a giant space-based observatory made up of multiple telescopes as well as using new technology such as nanosatellites
(a small spacecraft that carries light-detecting instruments) to measure changes in celestial objects from Earth-based observatories.
Regardless of what route NASA takes in the future, it seems clear that the legacy of Hubble will live on for generations to come.
Endeavor to Continue
In 1990, the Hubble telescope was launched into space with great fanfare. Its mission was to observe distant objects in our universe and help us better understand
their makeup and behavior. In the years since, it has more than lived up to its promise.
The images and data it has sent back to Earth have helped us unlock many mysteries about our place in the cosmos. Among other things,
they’ve revealed new details about what’s known as dark energy and how it drives the expansion of the universe.
They’ve helped identify planets outside our solar system for study by NASA’s Kepler spacecraft.
And they’ve also given scientists a way to measure changes in Pluto’s atmosphere as Pluto travels on its long journey from inside Neptune’s orbit at 30 AU
(astronomical units) out toward aphelion at 49 AU over a period of six billion years—one third of time from when Pluto first formed. As we explore farther and farther beyond
our home planet, the most powerful tool we have is the Hubble Space Telescope, which continues to be an invaluable asset for all
those who want to know more about our cosmic origins.
Despite being one of the greatest scientific accomplishments of all time, no one ever said that building such a tremendous instrument would be easy.
Although it only took five months to construct after workers assembled parts brought together across Earth,
much work went into creating these components before they were sent up there.
The primary mirror for example was originally created at Perkin-Elmer Corporation’s Danbury Optical Systems facility in Danbury Connecticut –
but due to its size could not fit through any door or hallway leading from component construction areas to assembly areas and had to be disassembled by hand!
This process required specialized tools and techniques,
such as construction scaffolding around each individual mirror segment so that engineers could safely handle them without dropping them onto equipment or facilities below.
