The Comet. It Sings!

Have you heard the comet singing? From the Rosetta Blog this press release: Rosetta’s Plasma Consortium (RPC) has uncovered a mysterious ‘song’ that Comet 67P/Churyumov-Gerasimenko is singing into space. RPC principal investigator Karl-Heinz Glaßmeier, head of Space Physics and Space Sensorics at the Technische Universität Braunschweig, Germany, tells us more.

Philae and Philae: Separated at birth?

Just so you know, Philae is a lander planning to land on a comet at this moment being landed on by an Earthling Spacecraft, and it is also an island in the Nile. Before the Rosetta space craft got close, we had no idea what the comet looked like. Now we do. And it looks…

Don’t forget to look up tonight!

Auroras are amazing sites because they are, of course, impossible. When Amanda and I got married a year or so ago in northern Minnesota, there was an amazing Aurora, surpassing what anyone at the wedding had ever seen in the state. Big colored curtains of light. Tonight, and over the weekend, the northern lights will…

Remember that asteroid that was supposed to pass harmlessly by the Earth on Sunday? Well, things didn’t go exactly as planned… Apparently, a meteor hit Nicaragua late Saturday night, forming a 12 meter wide crater. This would be a small chunk to make a crater that little. It has not been confirmed yet, but there…

Near Earth Object Will Be Near Earth

Phil Plait says “Don’t Panic!” and he should know because he is the Death from the Skies!: The Science Behind the End of the World which is about things hitting the earth. The object is called 2014 RC and it was discovered on September 2nd. It will arrive on Sunday. The object is about 20…

We know know what the famous announcement by the European Southern Observatory is. They found an asteroid with ring! Two of them! …the remote asteroid Chariklo is surrounded by two dense and narrow rings. Telescopes at seven locations in South America, including the 1.54-metre Danish and TRAPPIST telescopes at ESO’s La Silla Observatory in Chile…

UPDATED: THIS is the discovery. The European Southern Observatory will make an announcement tomorrow (or later today depending on where you read this, but Wednesday) about an amazing new discovery they made in outer space. I’m not going to tell you what they found because it is top top secret. But it is very interesting…

If you missed the first (or later any) episode of Cosmos 2014, you can get it on Amazon Prime streaming (for a fee). It’s worth it. Here are a few comments I jotted down (then lightly edited) while watching the first episode. Neil does have his own spaceship, like Carl did. That’s important because it…

Look at the rock on the right, and the lack of rock on the left. (Our left.) It is being reported that this jelly-donut size rock appeared out of nowhere on the Martian surface between photographs. There are several possible explanations for this. 1) It grew there. 2) It was ejected from a steam vent…

He who lives by gravity shall die by gravity. That’s what they say in the gravity biz, anyway. GROCE is the European “Gravity field and steady-state Ocean Circulation Explorer” Satellite which is a flying spacxe robot that has done some amazing research: GOCE has a gradiometer with three accelerometers to measure gravity very accurately, to…
