Scientists see 1800 new supernovas in the distant universe in remarkable discoveries using the Subaru telescope
- New supernova & # 39; s were spotted with the 8.2-meter Subaru telescope in Hawaii
- Scientists have discovered up to 8 billion light years away, the team said
- The findings could lead to more accurate calculations of the expansion of the universe
Scientists have seen thousands of dying stars during their blast.
A team running the 8.2-meter-long Subaru telescope in Hawaii says they have found around 1,800 new supernovas, up to eight billion light years away.
The heap of new data, including several supernovas of a type known to be useful in calculating the distance of stars, could help unlock new clues about the expansion of the universe, researchers said.

A team of researchers from the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU), Tohoku University, Konan University, the National Astronomical Observatory of Japan, School of Science, Tokyo University and Kyoto University made the findings published week in the publications of the Astronomical Society of Japan.
Although supernova are rare events, astronomers were able to take ultra-sharp photos with Suparu's Hyper Suprihyper suprimeme-Cam, an 870 mega-pixel camera that can capture large angles at once.
In the final attempt, the team repeatedly portrayed the same part of the night sky over the course of six months, revealing that the supernova is hiding in the distant universe based on how stars changed into brightness.
The discoveries included five super-light supernova & about 400 Type Ia supernovae – of which 58 were more than 8 billion light-years away.

This was possible thanks to the advanced capabilities of the Subaru telescope; it took Hubble more than 10 years to discover a similar number of supernovae.
& # 39; The Subaru telescope and Hyper Suprime-Cam have already assisted researchers in making a 3D map with dark matter and observation of original black holes, but now this result proves that this instrument has a very high ability to supernova & # 39; s very far away from the Earth, & said Professor Naoki Yasuda.
The new cache of Type Ia supernovae will help scientists more accurately calculate the expansion of the universe.
The discoveries can also shed light on the nature of dark energy.
WHAT IS A SUPERNOVA AND HOW IS THE FORM?
A supernova is created when a star explodes and shoots debris and particles into space.
A supernova only burns for a short time, but it can tell scientists a lot about how the universe started.
A kind of supernova has shown scientists that we live in an expanding universe, one that is growing at an ever-increasing pace.
Scientists have also found that supernovae play a key role in spreading elements throughout the universe.

Two types of supernova are known.
The first type occurs in binary star systems when one of the two stars, a carbon-oxygen white dwarf, steals matter from its companion star.
Eventually the white dwarf collects too much matter, causing the star to explode, resulting in a supernova.
The second type of supernova occurs at the end of the life of a single star.
Because the star no longer has nuclear fuel, part of its mass flows to the core.
Ultimately, the core is so heavy that it cannot bear its own gravitational force and the core collapses, resulting in a new giant explosion.
Many elements found on Earth are made in the core of stars and these elements continue to form new stars, planets and everything else in the universe.
