Pluto Has Tail, X-Rays

Did you ever notice that Pluto doesn’t have much of a tail? No, not that Pluto! This Pluto: This has been known for a while. NASA noted this last year: New Horizons has discovered a region of cold, dense ionized gas tens of thousands of miles beyond Pluto — the planet’s atmosphere being stripped away…

The star that is nearest our own has a planet that could be habitable by Earthlings. This is very important news. The news comes to us from this research paper in Nature: A terrestrial planet candidate in a temperate orbit around Proxima Centauri by Guillem Anglada-Escudé, Pedro J. Amado, John Barnes, Zaira M. Berdiñas, R.…

Ethan Siegel on The Universe

Check out our detailed interview with the famous and amazing Ethan Siegel. We talk about the history of understanding the universe, why you should believe in Dark Matter even though it is obviously fake, why exploring uranus can lead to the discovery of amazing things, and more.

Happy Anniversary Exoplanets

This month is the twentieth anniversary of the discovery of exoplanets, which are really just planets that are not in our solar system. (Frankly, I dislike the term exoplanet. It is so solarcentric.) When you think about it, the discovery of planets outside our solar system (we need a word for that) is a special…

That Orion Thing Is Great!

Watch the Orion test flight: Splashdown: Why is it great? Well, speaking as a Gemini (not my horoscope sign, but the space program going when I first gained sentience) … First, it is big, fast, cool looking. It actually looks like a rocket that might have been designed a decade before they ever actually made…

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…

Neil DeGrasse Tyson on CNN: And while we are on the topic, Carl Sagan, of the original Cosmos, on climate change: See also this from Chris Mooney at Mother Jones. And just for the heck of it, here’s my interview with Neil deGrasse Tyson from 2011.

There are bacteria that use Iron (and other elements) to make tiny magnets that they carry around so they don’t get lost. (I anthropomorphize slightly.) There are isotopes of Iron that are not of the Earth, but are found only elsewhere in the universe. Suppose an event happened elsewhere and spewed some of that cosmic…

I love it when scientists say that! And, so said scientist Daniel Baker, speaking of a newly observed feature of the famous and well known, or at least, we thought well known, Van Allen Belts. First discovered in 1958, the Van Allen belts have been thought to comprise two reservoirs of high-speed, electrically charged particles,…

In February, Asteroid 2012 DA 14 will come so close to earth that it will be nearer to our planet than many satellites are. This asteroid, which really should get a new name, is about half the size of a football field. Its orbit is similar to that of the Earth itself, in size and…
