When you’re talking to spacecraft billions of miles away, you need a powerful voice. And when you’re listening for their faint replies from those same staggering distances, you need an even bigger set of ears. Fortunately, NASA’s Deep Space Network has both — and last week I had the chance to see some of them up close…

Voyager 1: It’s Officially Out
“We made it! 35 years and 13 billion miles.” Those were the words of project scientist Ed Stone today during a NASA news conference about the Voyager 1 spacecraft, which, after traveling the far reaches of our Solar System for decades on end, has finally passed the physical boundaries of the heliosphere and entered interstellar…
“Like L.A. Smog on Steroids” – Cassini Scientists Pick Apart Titan’s Haze
Scientists working with data from NASA’s Cassini mission have confirmed the presence of a population of complex hydrocarbons in the upper atmosphere of Saturn’s largest moon, Titan, that later evolve into the components that give the moon a distinctive orange-brown haze. The presence of these complex, ringed hydrocarbons, known as polycyclic aromatic hydrocarbons (PAHs), explains…
Win a DVD of NOVA’s Excellent “Earth From Space”
Earth… our home planet, a brilliant “blue marble” tirelessly turning through space on an endless journey around the Sun and across the galaxy. Basically a ball of molten rock and metal, its relatively thin crust is mostly covered by a sea of liquid water as well as wrapped in a sea of air… and it’s…
Space Book Alert: Your Ticket to the Universe

How Big Is The Solar System?
“You may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.” – Douglas Adams Standard classroom models and textbook illustrations of the Solar System, regardless of how pretty they are, all share one thing in common: they’re wrong. Ok, maybe not wrong, but definitely inaccurate… especially in regards…
