    These findings are limited, and further investigation before we can say for sure.

    Motivated by the possibility that a cooling delay caused by crystallization can be directly detected for this white dwarf we employ a variety of methods to constrain the age of the system; however, our empirical age anomaly of +3.1±1.9 Gyr is ultimately too imprecise to reach statistical significance, preventing us from making strong constraints to models of white dwarf crystallization.



  • In this simulated view of Mars with enhanced color and contrast, darker grey-toned areas of Mars represent grey-black basaltic sands of volcanic origin; lighter patches show clay and sulphate minerals; and the large scar across the planet’s face is Valles Marineris.

    These photos are heavily exaggerated, with their contrast boosted. It’s a great way to visualize the rock and mineral composition in different regions. To the naked eye, Mars would look pretty much as you’d expect. Still really cool though!

    You can actually find similar photos of the moon, too. Wallpaper material for sure.

    “We found that the more time people spent in space, the larger their ventricles became,” said Rachael Seidler, a professor of applied physiology and kinesiology at the University of Florida and an author of the study. “Many astronauts travel to space more than one time, and our study shows it takes about three years between flights for the ventricles to fully recover.”

    Space has proven challenging for the human body. I know that prolonged habitation affected bone density and increased the risk of kidney stones, but are there any other well-documented health concerns?

    [EDIT] I looked into it and found a few other concerns:

    • Vision problems
    • Muscle density loss
    • Radiation sickness ( ! )
    • Weakened immune system
