How Life on Earth Began

One of the most important questions our species has tackled is the origin of life on Earth.  If we can figure out the conditions and catalyst for the beginning of life, we can look elsewhere in the universe for those same conditions, and zero in on the potential for finding extraterrestrial life.  We know the universe is old enough for the painstakingly slow evolutionary process, but what started it? In the famous 1952 Miller-Urey experiment, a flask containing the basic natural elements water (H20), methane (CH4), Ammonia (NH4), and Hydrogen (H2), all present on the early Earth, was subjected to...

Supernova is a Good Name

If you listen to an astronomer talk about a supernova, you’ll probably hear something along the lines of ‘A massive explosion of a massive star that is bright enough to outshine an entire galaxy.’  You can imagine how bright it might be, but it doesn’t really give you enough context to get the wow factor from it.  Carl Sagan always said ‘When you make the finding yourself – even if you’re the last person on Earth to see the light – you’ll never forget it.’  Now you, dear reader, have the chance to make the discovery yourself.  A series of images of galaxy...

Earth Suspended in a Sunbeam

As 2015 wraps up, I wanted to share one of my favorite quotes and perspectives, from none other than Carl Sagan, arguably the greatest science communicator in history. “Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love,...

Gravity Waves or Not? Big Discovery May Need a Tune-Up

Last year we received some incredible news about Cosmology and the Big Bang.  An experiment devised to find the signature of the inflationary model of the Universe told the world they had done it!  The world cheers, as did many scientists; but of course there are always reasons to be sceptical, especially with claims that have such an impact for humanity let alone the science world. And now it seems the scepticism was correct, as the conclusive result has now been deemed inconclusive.  This doesn’t mean its false, not by a long shot, but it does mean the research team...
