WTF? After they demoted Pluto to a planetoid, are they about to tell us that there are two other planets in our solar system? Remember when they told us we had 9 planets in our solar system and that was settled? Let me tell you something: science is never settled. What will they call these 2 big planets out so far from the sun that they probably make Pluto look like the tropics? Maybe … Read more

The Universe got a little more amazing today. Thirty years ago, the theory of cosmic inflation was proposed. The idea is that, for about one billion billion billion billionth of a second, the universe expanded faster than the speed of light.
The inflationary theory explained a lot of things, such as the remarkable smoothness of the universe. And it had some interesting implications, such as the potential existence of other universes, perhaps with different laws … Read more
We don’t say this enough in science: holy shit!
A meteor that exploded over Russia this morning was the largest recorded object to strike the Earth in more than a century, scientists say. Infrasound data collected by a network designed to watch for nuclear weapons testing suggests that today’s blast released hundreds of kilotonnes of energy. That would make it far more powerful than the nuclear weapon tested by North Korea just days ago
A little mental health break from the Super Tuesday madness. Listen to this and you’ll know why Neil DeGrasse Tyson usually has a flock of trailing admirers at conferences (and yes, cheesy music does actually follow him around):
Our universe just got a little more interesting:
NASA’s Kepler mission has confirmed its first planet in the “habitable zone,” the region where liquid water could exist on a planet’s surface. Kepler also has discovered more than 1,000 new planet candidates, nearly doubling its previously known count. Ten of these candidates are near-Earth-size and orbit in the habitable zone of their host star. Candidates require follow-up observations to verify they are actual planets.
Or at least a few billion years:
Astronomers have spotted an exotic planet that seems to be made of diamond racing around a tiny star in our galactic backyard.
The new planet is far denser than any other known so far and consists largely of carbon. Because it is so dense, scientists calculate the carbon must be crystalline, so a large part of this strange world will effectively be diamond.
The evolutionary history and amazing
I’ve been scratching my head for a long time, trying to figure out why NASA hasn’t been taking the idea of preventing asteroid impacts more seriously.
So I’m pretty chuffed that the European Space Agency is looking into saving our collective skins. They’ve being studying the feasibility of a mission to test methods of asteroid impact mitigation, including a very very cool space mission they’ve dubbed Don Quijote (first proposed in 2002,
