20 Educational Apps Approved By Parents While it can seem that they take to the proliferation of gadgets and apps more naturally than we do, it’s incumbent upon us to try as hard as we can to stay ahead of the game and ensure that their tech time is spent constructively. The best approach is to be proactive and provide kids with fun, enriching activities in the digital realm. Here are Best College Online’s recommended educational apps and other electronic products: Shake-a-Phrase From Artgig Studios, this $1.99 app for the iPhone and iPad makes language learning fun. DragonBox Available for iPhone, iPod Touch Mac, iPad, and Android, this virtual card game does something brilliant: it begins to teach kids algebra without their knowing it.
El día más largo de mi vida | Un año en el polo Sur a la caza de neutrinos 15 Octubre 2012. La pista de aterrizaje preparada y las señalizaciones colocadas para recibir los primeros aviones de la temporada pasada. Welcome to “The Longest Day in my Life”, a blog about the experience of spending a full year at the South Pole hunting for neutrinos. If you are interested in Antarctica, life at South Pole, the polar night, neutrinos or Astroparticle Physics in general, come have a look, feel at home… If you know spanish and find untranslated content, feel free to help with translation.

Stellarium Official Source of Cassini images of Saturn, its rings & moons Captain's Log November 12, 2013 Four months ago, our cameras on Cassini were commanded to execute a routine imaging sequence during an event that was anything but routine. On July 19, an array of overlapping images framing Saturn, its entire ring system and a host of its moons was acquired while Cassini was deep in the shadow created by the planet's eclipse of the Sun. This arrangement of Sun, Saturn, and machine made for a rare opportunity to image from the outer solar system the planets in close to our star. Images of this nature had been taken before. And contemplate, appreciate, marvel and rejoice they did! From Pennsylvania: 'What a great way to feel connected to the universe, the planet, and every single person on it. From England: 'What a privilege to be part of such an event with so many people world-wide.' From somewhere unknown: 'At the appropriate time, I turned my face to the sky & spent a few minutes watching & listening to what life on Earth was like, right there.
Mapping The Universe A new map of our complex universe is out. We’ll look at our “chunky” cosmos. We look up at the night sky and marvel at its depth and beauty. Its constellations and its stupendous scale. And then on a curious night we wonder, what is all that? It turns out this is a very good moment to ask. We know more than we have ever known. –Tom Ashbrook Guests Charles Lawrence, lead U.S. scientist for Planck mission at NASA’s Jet Propulsion Laboratory and co-chair of the Planck editorial board Sean Carroll, theoretical physicist at the California Institute of Technology, writer for Discover’s Cosmic Variance blog, and author of “The Particle at the End of the Universe: How the Higgs Boson Leads Us to the Edge of the World” (@seanmcarroll) Collected Show Highlights You can listen to all the clips here, or see them individually further below: Individual Show Highlights Carroll and Lawrence mused about big question of whether the universe is finite or infinite. I don’t distinguish between those. Playlist
W. M. Keck Observatory Terry Hancock Astrophotography - Home In-situ Probing of Radiation-induced Processing of Organics in Astrophysical Ice Analogs—Novel Laser Desorption Laser Ionization Time-of-flight Mass Spectroscopic Studies - Abstract - The Astrophysical Journal Letters Understanding the evolution of organic molecules in ice grains in the interstellar medium (ISM) under cosmic rays, stellar radiation, and local electrons and ions is critical to our understanding of the connection between ISM and solar systems. Our study is aimed at reaching this goal of looking directly into radiation-induced processing in these ice grains. We developed a two-color laser-desorption laser-ionization time-of-flight mass spectroscopic method (2C-MALDI-TOF), similar to matrix-assisted laser desorption and ionization time-of-flight (MALDI-TOF) mass spectroscopy. Results presented here with polycyclic aromatic hydrocarbon (PAH) probe molecules embedded in water-ice at 5 K show for the first time that hydrogenation and oxygenation are the primary chemical reactions that occur in astrophysical ice analogs when subjected to Lyα radiation. We found that hydrogenation can occur over several unsaturated bonds and the product distribution corresponds to their stabilities.

One-Minute Astronomer - Star Gazing and Basic Astronomy Bad Astronomy Well now, this is an interesting discovery: astronomers have found what looks like a "super-Earth" – a planet more massive than Earth but still smaller than a gas giant – orbiting a nearby star at the right distance to have liquid water on it! Given that, it might – might – be Earthlike. This is pretty cool news. We’ve found planets like this before, but not very many! And it gets niftier: the planet has at least five siblings, all of which orbit its star closer than it does. Now let me be clear: this is a planet candidate; it has not yet been confirmed. The star is called HD 40307, and it’s a bit over 40 light years away (pretty close in galactic standards, but I wouldn’t want to walk there). Massive planets tug on their star harder, so they’re easier to find this way. In this case, HD 40307 was originally observed a little while back by HARPS, and three planets were found. We don’t know how big the planet is, unfortunately. That’s exciting because of the prospect for life.
