How Hot Can It Get?
We all know that absolute zero is the theoretical lowest possible temperature, but what about an absolute hot?
Claims of water being present on Mars have existed since 1870 with the first quantities of water actually being detected in 2003 by the Mars Odyssey spacecraft.
Now, according to an article published yesterday in the journal Geology, there is evidence that Mars is home to vast reservoirs of water in its interior as well. The utility of this evidence comes in the prospects of extraterrestrial life (no, not full fledged aliens) and future human colonisation.
The research itself did not require any samples from Mars; rather, by analysing the water content of two meteorites ejected roughly 2.5 million years ago, they were able to determine that Mars has somewhere between 70 to 300 parts per million of water in the mantle - a figure that is not too far from that of Earth’s 50 to 300 parts per million.
If all of this can be deduced from two meteorites that crashed on Earth over a century back, only time will tell what future missions to Mars could yield.

On This Day: 9/27/1905 Albert Einstein Describes Space & Time
Happy Birthday E=mc^2! Now turning 106 years old
Albert Einstein (1879-1955) is considered by many the greatest astrophysicist. He is pictured here in the Swiss Patent Office where he did much of his great work. Einstein’s many visionary scientific contributions include the equivalence of mass and energy (E=mc^2), how the maximum speed limit of light affects measurements of time and space (special relativity), and a more accurate theory of gravity based on simple geometric concepts (general relativity). One reason Einstein was awarded the 1921 Nobel Prize in Physics was to make the prize more prestigious.
September 27, 1905 is generally considered the birthday of the equation because that is the day that Einstein’s paper outlining the significance of the equation arrived in the offices of the German journal Annalen der Physik.
And here I was imagining that it was only Google’s self-given birthday… Happy birthday to the mass-energy equivalence! (that is arguably as weird as it sounds)
And now, a new planet that could potentially support life has been discovered! This however, is all dependent upon cloud coverage across the planet and whether it is sufficient to support the existence of water. However, the fact that it is around 36 light years away could serve as a slight problem if plans are ever made, in case of emergency or otherwise, to travel there. Maybe in the future…
