It's more than just a weird shadow this time, planetary geologist Steven Ruff and geobiologist Jack Farmer have seen something on Mars that could indicate life was there.  NASA's Spirit Rover took the above image in 2008. They say that the 'cauliflower-like' deposits of minerals seen in this picture could have been formed by microbes. 

The area this photo was taken on Mars is thought to have been a center for hot springs and geyser activity.  The same kind of mineral shapes have been found in Atacama desert in Chile.  



The Atacama desert is often compared to the conditions on Mars and even used as a practice area by NASA for the real thing.

Mercury, Venus, Saturn, Mars and Jupiter will be visible to the naked eye to stargazers in the early mornings during February.  The last time this happened was in 2005 so it's a rare sight to see. According to the video, if you miss the event this February, you may be able to see the same thing in the evening sky this August. 

Uh... is no one else worried about this happening?:

An earlier theory used to be that the moon hit the Earth on the side (as in the video below) but this stunning image is a reconstruction by scientists who say that it was a head-on collision that caused the impact. 

Edward Young, lead scientist of this study told UCLA Newsroom that they drew this conclusion from the fact that the Earth and the Moon are overwhelmingly made of the same materials. 

“Theia was thoroughly mixed into both the Earth and the moon, and evenly dispersed between them,” Young said. “This explains why we don’t see a different signature of Theia in the moon versus the Earth.”

He even took time to explain the science behind a few examples of 'proof' of a flat Earth and why they are so, so wrong. 





UPDATE to the update, B.o.B. has just released a song aimed directly at Neil deGrasse Tyson and all about the flatness of Earth. NSFW Warning: This song contains a few words that are not appropriate for the scientific community.

Have you checked your pinky for deformities lately?  Go ahead, we'll wait....
If you noticed a dent or curve in your pinky finger and you own a smartphone you may have 'smartphone pinky' from holding your phone too much. 

Great, one more thing to worry about.

Except, don't worry about this. Your pinky finger is probably totally normal.

According to Popular Science, it's most likely a natural curve of the pinky that a lot of people have or a dent that will go away just like the lines on your face after sleeping face down on your pillow. At worst, it could be a repetitive strain injury from something other than just holding your phone but you would probably know the difference because your pinky would likely also be in pain. In which case you should see a doctor, but not because your smartphone is deforming you.

What are these glorious golden space swirls? According to NASA, who captured this video with the Solar Dynamics Observatory (SDO), this happened when a dark solar filament erupted and caused a chain reaction.They call these cascading magnetic arches because what you see here is a lot of particles spinning around the sun's magnetic field lines. 

Here's a video where you can see what a dark solar filament looks like. The darker area, almost in the shape of a circle is it. Filaments are plasma held above the sun's surface by magnetic forces.

This is one of the largest new dinosaurs ever discovered. It's so new, it hasn't even been formally named by paleontologists.  It probably weighed about 70 tons.  Now a cast of the bones is on display at the American Museum of Natural History. 

Here's a video of how they put it all together:
