Back in 1990, NASA and the European Space Agency, or ESA, have launched a telescope especially created to search and analyze the deep places in our Universe. Above Earth‘s atmosphere, the spacecraft is able to peer around and see with no biases from air, light, and pollution.
When researchers launched it, they said it would last for a decade, but 30 years later, the Hubble Space Telescope continues to amaze the world with its findings. Its famous captures have helped astronomers understand some of the most challenging questions about the Universe, such as how old it is, or if black holes do indeed exist. They now believe that the Universe is about 13.8 billion years old, and yes, black holes do exist, with frightening savageness.
Expected to Work Alongside James Webb Space Telescope
In 1995, astronomer Bob William had a new idea, namely, to point the Hubble Space Telescope at an apparent dark area in the sky. That led to the spectacular discovery that even where the human eye is unable to see, thousands of galaxies exist.
“One of Hubble’s lasting achievements will be how it showed the public the wonders of the universe,” says Kenneth Sembach, director of the Space Telescope Science Institute, which manages Hubble’s science program.
The satellite is already 30 years old, but it was designed in a way that allows it to be repaired and upgraded when it is needed. Since its launch, there were five space shuttle missions that have transported astronauts to the telescope in order to repair it. The last upgrade mission took place in 2009, and it is expected to be the last.
Next year, NASA intends to launch the James Webb Space Telescope, which will work together with Hubble in order to collect even more information about the Universe and answer a lot of other long-standing questions.
