UNAWE - Explosions Help Us Measure Distances in the Universe

https://spacescoop.org/en/scoops/2217/explosions-help-us-measure-distances-in-the-universe/ How do astronomers measure extremely large distances in the far away corners of the Universe? So this would be the top step on the cosmic distance ladder.   An international team led by Dr. Maria Dainotti, an Assistant Professor at the NAOJ, the National Astronomical Observatory of Japan, has just found a new way to do it. This is because it is quite hard to find standard candles bright enough to be seen more than 11 billion light-years away from us.    You see, the farther out in space we look, the further back in time we see and the closer we get to seeing the Big Bang, the harder it is to find these objects. At 11 billion light-years away from us, these objects get rarer and rarer.    We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
