Supernova spectacle: Gravitational lensing reveals star explosion 4 billion light-years away!

An unusual image of a supernova, the tremendous explosion of a star, has been taken by astronomers. The galaxy’s gravity has bent the star’s light, causing it to appear as multiple images in the sky.

This gravitational lensing phenomenon occurs when the gravity of a denser object bends and magnifies the rays of an object behind it.

The rare Type Ia supernova known as “SN Zwicky” was revealed to be quadruply-lensed, meaning that four images of the same supernova can be seen from Earth. The discovery was made by an investigation led by Ariel Gober from the Oscar Klein Center at Stockholm University.

Christopher Fremling, a staff astronomer at the Caltech Optical Observatory and project leader of the Bright Transient Survey that discovered the ZTF supernova, says: “I was watching that night and I was completely shocked when I saw the lensed image of SN Zwicky.”

The authors claim that SN Zwicky was magnified “about 25 times” by the foreground galaxy acting as a lens.

Gravitational lensing not only magnifies SN Zwicky, but also adds it to a class of supernovae known as “standard candles,” according to the research. This category relates to instances where astronomers can calculate distances in space using their well-known brightnesses.

The Zwicky Transient Facility (ZTF) was used to find the unusual brightness of the supernova. Additional observations were made using the Hubble Space Telescope, the Very Large Telescope and the WM Keck Observatory.

The team was able to gather a wealth of information through careful observation including spectroscopic data and precise imaging of SN Zwicky.

The supernova was captured in four images from different vantage points in the sky. The images showed that the supernova’s extraordinary brightness was caused by gravitational lensing.

The study has the potential to deepen our knowledge of dark matter, the expansion of the universe and the hidden cores of galaxies. The team stresses the possibility of using lensed supernovae such as SN Zwicky to search for mysterious dark energy.

According to Albert Einstein’s prediction made a hundred years ago, when light from a cosmic object encounters a dense mass while traveling towards Earth, it may undergo gravitational lensing.

Gravitational bending of light has been observed by astronomers since 1919, only a few years after Einstein proposed the theory, but the fleeting nature of supernovae makes events such as SN Zwicky difficult to detect.
