Is There any Liquid on Mars?
Not many scientists have invested as much time in studying Mars as planetary geologist at the University of Arizona in Tucson, Alfred McEwen, who is the primary investigator for the high-resolution camera on the MRO (Mars Reconnaissance Orbiter), which entered the Mars orbit in 2006. In the past decade, with more than 55 000 observations, we have only managed to inspect about 2% of Mars.
The most crucial finding came in 2011, with the potential discovery of water on the surface of Mars. This means there is a high possibility of some form of life on the Red Planet.
In the Nature Geoscience, Alfred McEwen and his colleagues presented analyses of more than 151 of streaks on Mars, and the possibility of containing some kind of liquid.
Alfred McEwen recently said that the atmosphere of the Red Planet is very dry, but there might be some pockets of groundwater on the planet today. Also, McEwen said that the water is probably very salty which makes it challenging for any form of life to develop.
We are learning a lot about Mars from monitoring its orbit. However, to fully understand Mars we have to go there and examine it up close. Scientists are talking about this option more than ever, but there is no plan, and we should never forget that mission is harder than it looks in Hollywood movies. Visiting and understanding the Red Planet is still science fiction, but scientists like McEwen are trying to examine the origins of Mars and any possible potential of life and water on that beautiful red planet.
Never Let Houseflies sit on Your Food
If you didn’t know, houseflies are spreading diseases every time they decide to spend some time on your favorite snack.
According to a new study, houseflies carry hundreds of different kinds of bacteria and spread diseases among humans more than we could imagine. This might not come as a surprise when you think about how many times houseflies land on feces and then right onto your food.
Although we might think we are not going to give up our favorite cupcake just because a houseflies landed on it a few minutes ago, we might rethink that decision. Researchers warn us not to consume food that has been sitting out for too long especially in nature because you never know what landed on that food while you were not watching.
“It will really make you think twice about eating that potato salad that’s been sitting out at your next picnic,” said Donald Bryant, Ernest C Pollard Professor of Biotechnology at Penn State University.
Flies pick up bacteria from feces and rotting food which they use to nurture their young. Furthermore, a fly’s legs are perfect for transferring the most microbial and dangerous content from one surface to another. So, next time a fly lands on your food, the best thing to do is to throw it away rather than eat it pretending nothing happened.
NASA has given us a new view of our planet like we never saw it before. A living, breathing Earth is visibly shown on the illustrations created by NASA. NASA used several satellites to provide us with different views of Earth, the only home we have. Their animation illustrates changing seasons from the North to the South.
Gene Carl Feldman, an oceanographer at NASA’s Goddard Space Flight Center, said: “These are incredibly evocative visualizations of our living planet. That’s the Earth, that is it breathing every single day, changing with the seasons, responding to the Sun, to the changing winds, ocean currents, and temperatures.”
The illustration also provides us with more information on how warming Arctic and global warming can be seen easily. From the tundra in Quebec to western Alaska, our planet is turning green as ice is melting rapidly.
There are some things that we must do in this age when we are developed enough to see our Mother Earth from a different perspective. In the age when technology is developed, the development of our mindset should follow as well, and we should do anything we can as a nation and as individuals to protect and save the Earth for the generations to come.
