Neptune is a fascinating planet. For example, its most memorable characteristic is its glorious blue hue.
Trees are some of the oldest organisms on the planet. While our lives pass by in the blink of an eye, many trees stand as silent witnesses—watching century after century roll on.

The Whirlpool galaxy (also known as Messier 51) is one of the most instantly recognizable galaxies known to man, and for good reason too.

Question: With the current human population, and its rate of expansion, together with the rate of consumption of natural resources, how long until the human race reaches a point of no return, and we simply have nothing left?

Image Credit: Kent Biggs These two stunning interacting galaxies might look very similar to the Whirlpool galaxy, but they are not.
Image Credit: SDO The past couple of days have been weird, the Sun has gone quiet. We are currently in the middle of solar maximum, which is the time during the sun’s 11 year cycle that our home star is suppose to be extremely active.
Image: Sam Van Aken This tree is a little peculiar to look at. It’s because this isn’t an ordinary tree, one might argue that it’s actually closer to 40 trees all wrapped up into one.

Let’s be honest, we all spend a bit too much time with technology. It’s currently 85º F (29º C) where I live, and am I outside enjoying the weather?
