The Distance to Mars: Measured in Pixels

I’m pretty sure that many people have trouble understanding stellar distances. Even Mars, one of the closest planets, is really far away by Earthly measurement standards. Check out this great and simple web animation on how far away Mars actually is from Earth.

Number of Microbes Living on Earth Drastically Lower Than Previously Thought

microbes-sea-bed

The floor of the ocean is home to 2.9×1029 single-celled organisms but this large number, 10 million trillion microbes for every human on planet Earth, is only 8% of the previous estimate of  35.5×1029. Jens Kallmeyer, a geomicrobiologist and his colleagues at the University of Potsdam in Germany have created the most accurate model of the geographical distribution of microbes in the marine sediment. They published their findings in the journal Proceedings of the National Academy of Sciences.

Earth’s Van Allen Radiation Belt’s Charged Electrons Heading for Space not Surface

van-allen-radiation-belts

The increase in solar activity has become quite obvious on Earth, thanks to the increase in auroras caused by geomagnetic storms, but while astronomers had previously believed that the Earth might be stripped temporarily of its radiation belts, causing the charged electrons to inundate the atmosphere, new data has shown that the deadly particles will actually be blown back into space.

Bus-Sized Asteroid Barely Misses Earth

asteroid-impact-earth

An asteroid about the size of a bus shaved by Earth in what’s been described as a near miss. However, experts weren’t concerned that it might have impacted. This isn’t uncommon and these types of asteroids are hard to see except when they come quite close to Earth.
