Stunning remains of an old star explosion 11,000 years ago broken by Nasa

NASA has released an amazing image showing the remains of an ancient and massive supernova.

The light of the original star explosion took about 11,000 years to reach Earth – in the late 17th century.

Experts believe that astronomers may have spotted it at the time.

But it is only now that NASA has been able to capture a detailed snapshot showing the remnants of the stellar space event.

From time to time, large stars collapse under the effect of vast cosmic clouds, igniting and creating heavy elements in their nuclei.

After a few million years, this material is expelled into interstellar space, reviving the formation of stars.

The expanding debris cloud named Cassiopeia A is an excellent example of this, which took place almost 12,000 years ago.

NASA managed to capture an image of explosive remnants with the help of the Chandra X-ray observatory and the Hubble Space Telescope.

It shows hot filaments and knots in the so-called "rest".

"Still expanding, the external shockwave is visible in blue tones," Nasa said.

"The bright spot near the center is a neutron star, the crumbling and incredibly dense remains of the massive star core."

It's the youngest known supernova remnant in our Milky Way galaxy.

It is also the most powerful extrasolar radio source in the sky – at least to our knowledge.

Astronomers believe that the supernova had to explode around 1667.

But NASA says that "strangely, astronomers of that time did not notice it."

John Flamsteed may have observed it on August 16, 1689.

He cataloged a star close to its position as "Cassipeiae 3", but did not recognize it as a supernova – but instead recorded it as a normal star.

Here's what you need to know …

The Hubble Space Telescope is a telescope that captures images in space.
It was launched in low Earth orbit in 1990 and is still fully operational.
The advantage of Hubble is that it takes pictures out of the Earth's atmosphere.
This means that the distortion of the atmosphere is suppressed, allowing a more accurate image capture
NASA's Hubble has captured some of the most detailed images of space ever recorded
The Hubble telescope was also able to accurately determine the rate of expansion of the universe
Hubble is also the only telescope designed to be served by astronauts in space.
Five different missions have been launched to repair, upgrade or replace parts of the Hubble telescope
It is believed that the Hubble Telescope could continue to operate until 2040
But his successor, the James Webb Space Telescope, is expected to be launched in March 2021.

This star was not noticed anywhere else, so NASA suspects that it was not particularly bright from the Earth.

The rest of the supernova was detected for the first time in 1947 by radio astronomers in Cambridge, England.

And astronomers finally calculated that the star's expansion was to have started in 1667.
