“Exploding Stars Captured by Hubble Telescope Solving Mystery of Universe Expansion”

Jakarta –

The Hubble Space Telescope captured five large exploding stars, or supernovae. Scientists think the explosion that appears this time can help solve the biggest mystery of astronomy, namely about how fast the universe is expanding.

Launch page Live Sciencea supernova has become one of the important benchmarks as a star explosion that produces abundant light.

This relates to the universe beginning as just a tiny speck in space some 13.8 billion years ago.

Shortly thereafter, there was the Big Bang explosion. For a century researchers have been trying to figure out how the universe evolved.

Using Two Methods

To find out, the researchers used two methods. The first method is a “standard candle” for calculating how fast stars and galaxies are moving away from Earth.

Another method, namely cosmic microwaves, is through the Big Bang radiation. But these two methods produce different answers.

An assistant professor of physics and astronomy at the University of Minnesota named Patrick Kelly, revealed that researchers have not fully identified the contents of the Earth. So scientists have not been able to figure out how the Earth could have developed in the first place.

“It’s still a puzzle,” Kelly said.

Previous Supernova Explosion

Kelly himself once found an explosion 4 times that appeared in 2014. This supernova appears in several locations because the extreme gravity bends the light of the supernova and creates a gravitational lens.

At that time they predicted there would be a similar explosion in 2015 and it happened.

After that, they continued their research and recorded it in a Journal of Science which was published last May 11. The researchers triangulated the measurements of the supernova’s location to calculate the new value of the Hubble constant.

They note that the value of the Hubble constant is much closer to the value from the cosmic microwave than the “standard candle” method.

They noted that the universe is expanding at a rate of about 41.4 miles per second, or 66.6 kilometers per second, every 3.2 million light years.

However, the findings do not end the debate; they are just one more method, among many, of studying the expanding universe.

“They didn’t rule out the supernova value [lilin standar],” Kelly said.
