https://www.youtube.com/watch?v=5KGPtDOiD-Q Science deniers have been with us for a very long time. Though Galileo’s quest to prove that Earth orbits the sun was correct, he eventually recanted his belief as punishment for heresy.

Understanding the nature of light in the Universe is the subject of one of the greatest failed experiments in history: The 1887 Michelson-Morley Experiment at Case Western Reserve in Cleveland, Ohio, United States. Their failure paved the road to Albert Einstein's important contributions about light, speed, relativity and ultimately the nature of t…
 
Hosted by Charles Fulco. Today we interview Dr. Mike Brown. He led a team of astronomers who discovered UB313, now called dwarf planet Eris, in 2005. This discovery led the IAU to, for the first time ever, define what the word "planet" meant. The other dwarf planets are Ceres, Makemake, Haumea and Pluto. Dr. Brown is a professor at the California I…

https://www.youtube.com/watch?v=vyy-awQmpm4 When we look outward into space, we’re looking backwards in time. That’s because light moves, at the speed of light. It takes time for the light to reach us. But it gets even stranger than that. Light can be absorbed, reflected, and re-emitted by gas and dust, giving us a second look. They’re called light…
 
https://www.unawe.org/kids/unawe2030/ New observations from the National Science Foundation’s NOIRLab and other telescopes have found a planet that doesn’t quite match how astronomers expected planets to form.
