We all love trees, right? They keep our planet alive. Our forests breathe carbon dioxide and release oxygen into the atmosphere, making the air safe to breathe for humans and animals. And even if we don’t realize the impact of trees on the habitability of the biosphere, most of us enjoy trees as yard decorations. And a great many of us abandon the odd practice of stunting the growth of the branches and growing trees as hedges, and instead let the trees spread their leaves to their full, majestic height and girth. No matter how we think of trees, they are a huge part of our lives.

But just how many trees are there on the surface of the Earth? Continue reading

NASA was established by a president of the United States—Dwight D. Eisenhower in 1958. NASA has long been pushed along by both George W. Bush and the current president of the United States, Barrack Obama. And John F. Kennedy was one of the most famous presidential advocates for the space race, back in 1961. Because NASA is a publicly funded program that thrives on both public and government support, it has to continually adjust its goals to match public opinion and presidential aims.

Imagine that for your entire life, you have been chained to the wall of a dark cavern. Behind you lies a flame, and between you and the flame parade objects that cast shadows onto a wall in your field of view. This is all you can see of your world: the two-dimensional shadows of objects you only dream of seeing. It is your only reality. Your shackles prevent you from seeing the true world, a realm with one additional dimension to the world you know, a dimension complex and very capable of explaining all that you see.

Guest Post – Can We Mine a Black Hole?

How about a dose of theoretical astrophysics to brighten our day? Or, should I say, darken? For what I’m about to tell you revolves entirely around the physics of black holes, and they aren’t called “black holes” for nothing. Nothing, not even light, can escape their immense gravitational pull. More frightening is the discovery that a monstrous black hole lies at the center of every large galaxy, including ours, the Milky Way.

But what if a light-devouring monster such as a black hole could be used to benefit humankind? After all, the reason black holes are undetectable is that no form of radiation can escape their event horizon. That means that no form of radiation we can see by reaches our eyes and telescopic instruments. But it also means that the radiation gets trapped in the black hole. And radiation means not only light, but also heat.

Though many Pluto fans would beg to differ, Pluto is no longer a planet. It has been classified as a dwarf planet in the farthest reaches of our solar system. It is one of a group of similarly icy worlds called Kuiper Belt objects, from where comets are thought to originate. Neptune, Uranus, Saturn, and Jupiter are also thought to have captured their rings and moons from this belt of objects. The Kuiper Belt is analogous to an asteroid belt, but it’s not full of asteroids. Its objects are more like dirty snowballs, like a snowball compacted together from such a thin layer of ground snow that some dirt gets mixed in as well. On Earth, you might end up with twigs and leaves in your snowball. In the Kuiper Belt, you’re more likely to find stone and iron. You better not get caught in a snowball fight out there!

The Hubble Space Telescope is the sort of telescope that is never forgotten. Astronomers and astrophysicists move onto other projects. New Mars rovers are built, new space probes are launched, different light is analyzed, new ideas are formulated. But when you ask a non-astronomer what they know of astronomy, immediately they reply, “Like those images from—what’s it’s name—Hubble, right?”
