The universe is under no obligation to make sense to you.

The New Horizons spacecraft just woke up from a nine year nap. It’s three billion miles away from home, and it’s about to fly within a few thousand miles of Pluto, giving humans their first up close view of the dwarf planet.

Finally! A black hole that you can visit and survive!

Want a trip through a black hole without having to experience that pesky death? You’re in luck. There’s a special kind of black hole that’s not just survivable, but might get you to another time, or another universe.

Black holes are, traditionally, the scariest things in the universe. Huge, mysterious, inescapable, they wander through the universe and eat everything that gets too close. “Too close” is defined by their event horizon. This is the point at which they go dark, because it requires so much energy to escape them that not even light can get away. Since not even a photon can cross the barrier, no event that happens inside the horizon can ever have an effect on people outside.

Unless, something very odd was going on in the center of the black hole. Most black holes spin - this is something that was discovered way back in the 1960s by physicist Roy Kerr. It wasn’t exactly a shock, because most of the material that collapses into a black hole was already spinning. Sometimes, however, the spin on Kerr black holes goes a little above and beyond. Ever spun a glass of water, or soda bottle, so that the liquid inside swirls? Sometimes, if you spin it enough, the liquid actually parts, leaving a clear center and a spinning ring of water around it. The same kind of thing can happen in Kerr black holes. Instead of a singularity at the center, there’s a ring. And you can go through the open portion of that ring without touching the gravitational crush.

What’s on the other side? A lot of people have wondered. Some people think that these kind of black holes might be our key to time travel. They might be wormholes that let us hop between different points of the universe. Or they might be portals to different universes entirely. First we’ll have to find a few, and then we’ll need a few volunteers to go through. Preferably ones that haven’t seen Event Horizon.

Io is the first Galilean moon of Jupiter, it is slightly larger than Earth’s moon.  Io experiences intense tidal heating due to its elliptical orbit and orbital resonance with Europa and Ganymede.  This makes Io the most geologically active moon in our solar system.  Io’s interior is composed of molten iron sulphide, and the surface is a crust of sulfur and silicon.  Io has more than 400 active volcanoes, which can eject lava plumes more than 500 kilometers above the surface.  Some of the material from Io’s volcanic eruptions leaves the moon and orbits Jupiter, producing a plasma torus.  Io also has lakes of lava called paterae, which can also create eruptions.  The most dramatic paterae are Loki, Tvashtar, and Tupan.  The constant volcanic activity creates a thin atmosphere of sulfur dioxide and sodium chloride.  Io is an interesting model for exoplanets with intense geological activity, such as COROT-7b.

Rónán (anglicized Ronan) is an Irish language male given namemeaning “little seal” (Rón meaning “seal”, and -án being a diminutive suffix). It may refer to: Legend tells of a seal who is warned never to stray too close to the land.

What are white holes? Many people are familiar with black holes as a 3-D hole that alters time and space where not even light can escape. However, what is our knowledge on white holes? Well, as your might suspect, white holes are the exact opposite of black holes. They expel matter into space at intense speeds with immense energy. Some cosmologists believe that on the other side of a black hole is a white hole. An interesting point that can either excite or disappoint you is that white holes cannot be entered from the outside. This means that there may never be physical proof of a white hole and will only stay in theories and mathematics.

Nevertheless, there is a paper written in 2012 that argued that the Big Bang was a white hole itself. Unlike black holes, white holes cannot be observed continuously and can only be observed at the time of the event. It also connects a new class called y-ray bursts to white holes. If you would like to read this interesting paper check out http://arxiv.org/pdf/1105.2776v2.pdf. Hopefully one day we can learn more about white holes and the mysteries they hold. The universe is fascinating and has secrets that are waiting to be unlocked the question is how much money are we willing to spend on the universe?
