Hubble Space Telescope Completes 25 Years In Space; 5 Breathtaking Images That It Took In The Course

Hubble Space Telescope was launched aboard the Discovery space shuttle twenty-five years ago to provide us with an "unobstructed view of the universe."

Over the years, subsequent missions have improved Hubble's photography skills even more. As of last year, the telescope had snapped more than 570,000 images of 30,000 celestial objects. Reportedly, it now generates 3-4GB of data each day.

Here are five breathtaking images that it took in the course of 25 years

Westerlund 2

According to NASA, this is a "brilliant tapestry of young stars flaring to life." It's a huge cluster of about 3,000 stars named for Swedish astronomer Bengt Westerlund, who discovered them in the 60s.

Horsehead Nebula

This image was capture two-years ago in infrared light. Horsehead Nebula is in the constellation Orion. According to estimates, the Horsehead formation has about five million years left before it too disintegrates."

NGC 5584

The NGC 5584 galaxy was one of eight galaxies astronomers studied to measure the universe's expansion rate, according to NASA.

Orion Nebula

More than 3,000 stars are forming in the cloud of gas and dust known as the Orion nebula, some of which have never been seen in visible light.

Whirlpool

The large Whirlpool Galaxy (left) is known for its sharply defined spiral arms. Their prominence could be the result of the Whirlpool's gravitational tug-of-war with its smaller companion galaxy (right), NASA said.
