Although the next-gen James Webb Space Telescope (JWST) is up and running and even almost ready to reveal its first full-color images of the Universe, the much older Hubble telescope won’t exactly fall short. The telescope that’s been in the Earth’s orbit for over 30 years has revealed a beautiful image of the Terzan 2 globular cluster that’s located in the Scorpius constellation.
In the latest “Picture of the Week,” Hubble captures Terzan 2 in all its glory and majesty! We can’t remember a better image of the globular cluster, but you know what they say that you live and you learn!
Our latest Picture of the Week features a portrait of a globular cluster: Terzan 2 in the constellation Scorpio. Globular clusters are stable, tightly gravitationally bound clusters of tens of thousands to millions of stars.

Scorpius is located in the Southern hemisphere of the sky, and it’s also one of the constellations that the Greek astronomer Ptolemy discovered during the second century. Scorpius is also one of the constellations that are present in the zodiac.
Researchers said about Hubble:
Each of the four operational instruments on Hubble is a masterpiece of astronomical engineering in its own right, and contains an intricate array of mirrors and other optical elements to remove any aberrations or optical imperfections from observations, as well as filters which allow astronomers to observe specific wavelength ranges. The mirrors inside each instrument also correct for the slight imperfection of Hubble’s primary mirror. The end result is a crystal-clear observation, such as this glittering portrait of Terzan 2.
During its over three-decade-old history, Hubble uncovered many important aspects of the Cosmos. The telescope’s observations contributed to uncovering the true age of our Universe, for instance: 13.7 billion years old.
It may be a bit amusing that until only about 100 years ago, astronomers thought that the Universe always existed and, therefore, never had a beginning in the first place. But it was thanks to an American astronomer that light was shed, as his observations regarding the everlasting expansion of the Universe brought proof that our Cosmos began to exist along with the Big Bang, an event that took place 13.7 billion years ago. That American astronomer was none other than Edwin Hubble, and NASA’s future telescope was named after him.
