Hubble snaps jaw-dropping image to celebrate its 30th birthday”

NASA and ESA celebrated Hubble Space Telescope's 30th birthday with brilliant star photography. Over three decades, the complex and correct spacial system supplies the scientists with the new data.

Since it commenced operations thirty years ago, Hubble has furnished us with a non-stop movement of stunning pix together with these, that have revolutionized our know-how of the universe.

The telescope, named for American astronomer Edwin Hubble, was created because astronomers at the USA space agency NASA wanted an observatory free of the Earth's atmosphere and human-generated light.

This new Hubble Space Telescope image captures just another day in the life of two young nebulas (one red, one blue) in theLarge Magellanic Cloud, a satellite galaxy of the Milky Way located about 163,000light-years away.

The image - showing giant nebula NGC 2014 and its neighbour NGC 2020 - has been nicknamed the "Cosmic Reef" because it looks like an undersea world.

In total, Hubble has made more than 1.4 million observations, with astronomers using these data to write greater than 17,000 peer-reviewed medical papers.

Narrowing the age of the universe down to about 13.8 billion years is one of Hubble's many achievements, as well as finding that the universe is not just expanding, but accelerating, a discovery which won the 2011 Nobel Prize in Physics. As a satellite of the Milky Way, the Large Magellanic Cloud (LMC) is close enough to be caught in the thrall of our galaxy's gravity, and it inches a little bit closer to our galaxy every year. According to the agency, the cosmic structure was created by a star that's 45 times more massive than the Sun.

These massive stars also unleash fierce winds that are eroding the gas cloud above and to the right of them.

While the Brain Coral is shaped by the influence of multiple stars, the smaller, blue NGC 2020 Nebula located on the left of the image is being sculpted by a single enormous stellar body roughly 15 times the mass of our Sun, and 200,000 times as bright. It is an example of a rare class of stars called Wolf-Rayet stars. It was clearly visible in several years of Hubble observations, which revealed it was a moving dot. It has ejected its outer layers of gas, sweeping them around into a cone-like shape, and exposing its searing hot core. The brightest and most dense areas of the image show super star clusters representing some of the newest material in space.

"The Hubble Space Telescope has shaped the imagination of truly a whole generation, inspiring not only scientists, but nearly everybody", said Professor Gunther Hasinger, ESA director of science. A total of five shuttle missions were launched to service, fix and upgrade the telescope at massive cost, but it has most definitely been worth it.

NASA's Hubble Telescope is probably the agency's most successful telescope. Yet they play a crucial role in shaping our Universe, through stellar winds, supernova explosions, and the production of heavy elements.
