Remember the big picture of Andromeda that showed 100 Million stars? That image resulted in a ton of new galaxy discoveries. Most of these new galaxies were once hidden beyond the Andromeda galaxy, but with the super high resolution image, astronomers and the public were able to look straight through and see far more distant objects. Most images of galaxies have what we call ‘field stars’ in them. These are some of the 400 Billion stars of the Milky Way that are far closer than the galaxy we are imaging. For this reason, galaxy images tend to look very cluttered...
Stars are far apart, especially compared to the everyday distances in human experience. The fastest a human being has ever travelled is just shy of 40 Km/s, and even at that incredible speed it would take 30,000 years to reach the closest star. That is an incredible distance no matter how you slice it. Taking it a step further, most stars in the sky are 20-200 times further away, and that’s just the population of stars we can see. So if we go beyond and talk about galaxies and the distances between them, we are literally talking astronomical quantities. Yet even with...
You have to see this incredible feature on Mars, showing some of the best High-Res photos and milestones from the mission. http://www.nytimes.com/interactive/2014/12/09/science/space/curiosity-rover-28-months-on-mars.html As you look through the images, remember that you are looking at another world. It feels foreign, yet oddly familiar. You almost want to reach out and just grab a handful of sand. It makes you realize that we are not the center of the Universe. There are likely Billions of worlds similar to Mars, with Dunes and Soil and Skies and Mountains, except those world may not be so barren. They may be lush and alive, dominated...
