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.

Terminal World By Alastair Reynolds

Terminal World cover via Wikipedia

I finally managed to get my hands on Alastair Reynolds’ last book, Terminal World. One of the reasons why I had waited for a while is that the story was very steampunk-ish, and I don’t think that Alastair Reynolds should write steampunk. He should write hard science-fiction. Actually, I don’t really like reading about steampunk. I much prefer to read hard science-fiction, fiction, and fantasy.

Warning: Spoilers ahead.

Stargate Universe Earth S01E07 (Syfy)

SG°U title card, via Wikipedia

I’ve never been a Stargate fan. I’ve tried watching SG-1 and Stargate Atlantis, but never really found them compelling enough. I actually like the original movie with Kurt Russell, but the series never really interested me that much. One of my friends recently bought all of the seasons cheaply. I thought about watching them, but ran out of time. Scalzi is a creative consultant on this series and it looks pretty interesting, so I’ve decided to give it a go.

Now, before any bitching and hating starts― too late, it’s already started, I haven’t bothered to read, review, or watch any of the Stargate series, and I’m not going to. I’ve watched a couple of episodes and didn’t continue. I tried Stargate Atlantis, but didn’t like it. My friend told me that starting season 4, SG-1 was really good. I can’t really comment on that as I stopped watching the series after a few episodes.

Basically, I’m a new viewer of Stargate, but I’m not a science-fiction novice. It puts me in an interesting spot about reviewing this show. My point of view is from someone who hasn’t watched any of the SG shows, so this review and recap should be interesting to those of you who haven’t watched SG before. For the others, leave some comments and start a discussion.

Is the show good or bad? Read on to find out more.
