Asteroid Discovery Between 1980 and 2012.

Here is a video showing known positions of asteroids and other objects in the inner solar system. Knowing what we know now today in 2014, it almost makes you wish we didn’t know this much. The more the technology advances that is used to track these objects, the many more objects that are found. And apparently, this is only 1% of the total number of objects

A New Hubble Ultra Deep Field Image

Hubble Ultra Deep Field 2014

NASA has released an update to the Hubble ultra deep field image, something they do around once every couple of years or so. The images are spectacular views into the deepest realms of space. While I find these images absolutely amazing, what will really knock our socks off is the ultra deep field images that will be taken by the James Webb Space Telescope, currently set for launch in October of 2018. Webb’s images will probably make Hubble’s images look puny in comparison.

Beyond Neptune

There may be 8 planets and a series of dwarf planets in our solar system, but there a ton more objects being discovered all the time that dwarf the number of planets by a whole lot. Of course, most of these discoveries are in the Kuiper Belt. With all these items floating around and with most comets originating from the Kuiper Belt, is it any wonder that Earth hasn’t been pelted recently?

54 Years Of Space Exploration In One Beautiful Chart


So far, the only countries to send probes to other planets and moons in our solar system has been the United States and Russia (Soviet Union) and more recently India. During that time, hundreds of probes have visited the far reaches of our solar system and on July 14, 2015, the New Horizons spacecraft will reach Pluto and move on to the Kuiper Belt beyond Pluto’s orbit. To chart the history of planetary science, this fantastic visualization of all the space probe missions sent to planets and moons in our solar system was created by National Geographic. We have sent 72 probes to the moon, 38 to Mars, and probes to 8 of the “original” 9 planets, with New Horizons making that 9 next year.

Carl Sagan’s The Pale Blue Dot

The Pale Blue Dot, in addition to being an excellent book, is a monumental picture taken in 1990 by the Voyager 1 space probe and was taken at the behest of Carl Sagan. The space probe snapped this picture 3.7 billion miles away from the Earth and beyond the orbits of Neptune and Pluto. While the picture may not look like much, with Earth taking up just a few pixels in this image, Sagan describes it as such:

Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there–on a mote of dust suspended in a sunbeam.

There are many videos that have been created with Sagan narrating the text above, but the video above is one of the more new and slicker versions created.
