NASA's James Webb Space Telescope has spotted a distant supernova that appears three times in the same photo.
Jam packed issues filled with the latest cutting-edge research, technology and theories delivered in an entertaining and visually stunning way, aiming to educate and inspire readers of all agesThe distant supernova"H0pe" can be seen three times in the orange arc of light surrounding a galaxy cluster on the left side of this James Webb Space Telescope image. Other gravitationally-lensed objects are also labeled in this image.
The Hubble tension is based on a discrepancy between the two main ways of estimating the rate of the universe's expansion, known as thethat was first detected in 1964 — comes out with one value for the Hubble constant. But the second method, which involves measuring how far specific objects, such as galaxies and supernovas, are moving away from us, consistently comes out with a slightly higher value.
SN H0pe could help solve the Hubble tension because it is a type 1a supernova, which astronomers refer to as a"standard candle" — an incredibly reliable reference point from which we can measure the universe's expansion, Siegel wrote.
