New Horizons and Ultima Thule – Two Perspectives

This post is a collaboration with my good friend Bob Wegner, a professional musician, amateur astronomer, and genuinely good person. With the New Horizons spacecraft passing Ultima Thule on New Year’s eve 2019, Bob and I noticed that Queen guitarist and astronomer Brian May was on hand for the live event, playing a newly-written song […]

One Planet Hunter to Another

It wasn’t long after the discovery of exo-solar planets that scientists sent up spacecraft to look for them.  The Kepler Space Telescope (KST) was NASA’s first planet finder, which has been exceeding expectations since 2009.  It likely won’t get to continue on that road, as it is nearing the end of it’s life.  At the […]

Kepler Discovers 8-Planet System

Moments ago, NASA announced that the Kepler space telescope, for the first time ever, has discovered a star that has a system of 8 planets, similar to our own solar system. The exceptional part of the discovery is that it was found in existing Kepler data, using google artificial intelligence software that was trained to […]

The Ancient Collision That Everyone Saw

The year is 1987, and on February 23rd, three separate neutrino observatories experienced a huge burst in detections. Although initially unsure of their origin, the next day a Supernova was discovered in the Large Magellanic Cloud, a small satellite galaxy of the Milky Way visible in the southern hemisphere.  Known as 1987A, it was the […]
