No, I’m not talking about Orson Welles invading homes with his War of the Worlds radio broadcast (something I imagine would spread on social media today). I’m talking about radio signals from space finally resolving the Fermi Paradox: Where are all the aliens? Radio signals abound in space from natural phenomena, so an alien signal …

1st Known Alien Comet Visits Solar System
We are currently experiencing the first know visit by an alien comet to our solar system. Last Saturday, 7 December, marked its closest approach to the sun. The only other object ever detect coming in from deep space was a rock. This doesn’t mean this never happened before, only that we’ve recently gotten good at …
Image of a Black Hole Event Horizon
First image from the Event Horizon Telescope, a global collaboration of radio telescopes from around the world, all synthesized into one big virtual telescope. The whole point was to find out what a black hole looks like, and now we have it. This is a bit blurry and low-resolution, but still amazing when you realize …
Where are all the aliens?
An article in Science presents research showing that the building blocks of life are more prevalent than previously thought. It says a lot of other things too, but this is what I get out of it. This makes me wonder more than ever about the Fermi Paradox, which states that reasonable assumptions lead to the …
Energy resolution in nuclear weapons detection.
This paper was developed to introduce a metric that quantifies the role of energy resolution in the identification of nuclear isotopes.
