The search for extraterrestrial life continues! The latest insights come from our rover friend Curiosity which landed on Mars in 2012. While there may not be fresh liquid water, recent chemical experiments suggest the presence of some salt liquid water just below the Martian surface.

Ever since we took our first steps on the moon in 1969, scientists have been analyzing moon rocks and comparing their compositions with rocks on Earth to determine whether our Moon is a chunk of Earth that broke off or some other foreign space rock. In the past, most scientists thought the Moon was largely the latter... but recent chemical analysis tells a different story...??
from SciShow posted by Suzie Chhouk Just under 50 years ago, man took its first steps on the moon. Now we have probes and robots all over our galaxy! Though it'll still be decades until our first manned visits to the outer gas planets, our robots have been able to obtain some interesting chemical data from Jupiter and Saturn. from SciShow Space posted by Suzie Chhouk That's right - there is alcohol in our very own Milky Way! There isn't some sort of bar out there, however, all that dirty space dust can catalyze reactions to form complex molecules. Scientists suspect this may be the mechanism for the synthesis of amino acids - the basic building block for proteins... and maybe even life! from SciShow Space posted by Suzie Chhouk The last time you swam at the beach - did you notice it tasting a bit... sour? Hopefully, it wasn't sour to a degree that you could notice, but it is true that it is getting more sour. How? The ocean is becoming more acidic. How? Watch the video below. from Untamed Science posted by Suzie Chhouk I know this section is devoted to chemistry related to the Earth, but I would also like to use this space to introduce the chemistry we understand of the universe as well. Plasma is the fourth state of matter - and the most common state of matter in the universe! Yet, we don't hear so much about it in our most basic chemistry classes... but that's probably because we didn't even know about until the late 19th century. Have no fear, Michael from SciShow explains! from SciShow posted by Suzie Chhouk I know what you must be thinking - "What do you mean there's no such thing as cold?! We just started February, the coldest month of the year!" But bear with me for a second and allow me to explain -- scratch that, allow Joe from It's Okay To Be Smart to explain! But if you have any follow up questions or something you're still unsure about, feel free to ask me!

It's named in honor of Percy Bridgman, a scientist who won the 1946 Nobel Prize in Physics. Bridgman pioneered techniques that allowed scientists to synthesize and analyze minerals at pressures similar to those experienced deep within our planet.

If you're like me, you're still super scared off slipping on the ice and falling flat on your butt. Turns out scientists aren't completely sure why ice is so slippery - and your chemistry and physics textbooks might be wrong. from BrainStuff, of HowStuffWorks |
