More Evidence Our Solar System Is Uniquely Suited for Life

With over 2,000 extrasolar planets found around nearly as many stars, there's still no place like home.

Weekend Grab Bag

Here are links to recent science findings and claims sure to stimulate thinking and further research.

Supernova Dating and Classification Is Not Simple

Bang! goes a star. Watch how fast its contents move, and you know the date, right? Watch its light curve, and you know the type, right?

Planets and Moons Beneath the Surface

Can science peel back the surfaces of objects to see what's underneath? Can they go under the observations to find the explanations?

Earliest Galaxy Points Out Flaws in Secular Cosmology

More evidence points to a fully-formed universe very soon after the beginning.
