Not All Supernovae Are Created Equal: Rethinking the Universe’s Measuring Tools

Not All Supernovae Are Created Equal: Rethinking the Universe’s Measuring Tools

6/3/2025

Rethinking the Reliability of Type 1a Supernovae   How do astronomers measure the universe? It all starts with distance. From gauging the size of a galaxy to calculating how fast the universe is expanding, measuring cosmic distances is essential to understanding everything in the sky. For nearby stars, astronomers use... Read More >

Check out Brad Plumer's excellent article showing how we're changing our planet!

I'm going to talk about someone else's work based on yet another body of work for a minute here, but bear with me because it's worth it. I just ran across an excellent article written by Brad Plumer for Vox based on NASA's Images of Change series. Images of Change is a set of before and after remotely sensed images from various places on the Earth. What I like about Plumer's article is that he includes a wide range of types of change, mostly focused on changes caused directly by human activity. He then describes each of them succinctly and clearly for the lay person. I also appreciate that he includes examples of both destructive (e.g., deforestation) and productive (e.g., reductions in air pollution) changes.  

It's well worth a read. Check it out!
