   We are going to see a Supernova Predicted Supernovae of Star Betelguese         When you look at the Orion constellation, you notice some significantly bright two stars. Namely, they are - Rigel - the brightest blue one, and Betelgeuse - the bright red one. Recently scientists have found strange behavior from Betelgeuse.  In late 2019, astronomers detected strange dimming of Beteletguese. It loses almost 60% of its brightness, leaving a mysterious doubt behind. Astronomers think that it happened because of an internal thing that happened inside of this star, and obviously, they suggest that Betelgeuse is going to end its life soon, very soon. That "soon" is from the star's point of view. Because scientists think that it is going to go supernova in 10 to 100,00 years. Yeah, that's quite large, for a star, it's a bit small. Because an Average star lives at least 5 billion Earth years. Again it's large - because stars are LARGE! How it wil...

  Janith's Equation Janith's equation is a very complex equation found by Mr.Janith in 2023. Scientists show that this will change the whole world. Our Professor Mr.Sithumina says he had never seen an equation like this before. He also confirmed that this is accurate and acceptable.  After seeing this equation our Educational Minister - Mr. Sasen agreed to enter this equation into the Advanced Level Syllabus. He says that, to understand this equation students need much knowledge and experience, and he needs help understanding that.

Previously unknown bacteria discovered on the space station could help grow plants

  Previously unknown bacteria discovered on the space station could help grow plants Three previously unknown strains of bacteria were found growing in the International Space Station, according to a recent genetic analysis. The discovery could help scientists develop better ways to grow food on Mars. The analysis, published in the journal  Frontiers in Microbiology , describes how astronauts collected four strains of bacteria within the space station in 2011, 2015 and 2016. It was part of an ongoing surveillance program that tasks astronauts with monitoring eight sites of the space station for bacterial growth. Astronauts have already sent hundreds of samples back to Earth for analysis, and thousands more are scheduled to be sent back on return missions. The newly discovered strains belong to a family of bacteria called  Methylobacteriaceae , which is commonly found in soil and freshwater. These bacteria help plants grow, fix nitrogen and stop pathogens. Credits-Nasa Int...
