Sea Salt Covers Parts of Europa’s Surface
Scientists at NASA’s Jet Propulsion Laboratory found evidence that the dark material that covers parts of the surface of Jupiter’s moon Europa is probably sea salt produced by an ocean beneath its surface.
The researchers believe that the existence of sea salt on the moon’s icy surface implies that its sub-surface ocean is intermingling with its seafloor – something they say is a significant factor in determining if Europa can actually support life.
But this sea salt is discolored. Scientists said Jupiter’s strong magnetic field blasts Europa with a powerful force similar to what would be produced by a particle accelerator. It is believed that, as a result, the radiation discolored the salt, leaving it with a dark hue.
A study on the researcher’s investigation and findings has been accepted for publication in the journal Geophysical Research Letters and can be found online.
Naturally-Produced Sunblock Protects Some Animals From Sunburn
Did you ever wonder why certain animal species can spend their entire lives outdoors without getting a bad sun burn?
That’s because animals, including many species of fish, amphibians, reptiles, and birds naturally produce their own natural sunscreen.
Scientists from Oregon State University said the animals naturally produce a compound called gadusol, which provides a degree of protection from the sun’s harmful ultraviolet rays.
Unfortunately, mammals, including humans, don’t have the ability to produce this sun-blocking mixture.
Taking a Break between Secondary School and College? It’s Okay
Researchers at the Academy of Finland have some encouraging news for graduating secondary school students who want to take some time off before enrolling in college and parents concerned that a hiatus between high school and college could spell failure for their student
Taking a year off between secondary school graduation and beginning college does not weaken a young person’s enthusiasm to study, say the researchers, nor does it impact overall academic performance once the college term begins.
The researchers say those who do begin their college education immediately after secondary school graduation were more resilient in their studies and more committed to their study goals.
ISS Crewmembers Return to Earth Delayed
NASA said the schedule for space traffic to and from the International Space Station must be adjusted following initial investigative findings by the Russian Federal Space Agency – Roscosmos – on the recent loss of the Progress 59 re-supply spacecraft.
While exact dates of the modified schedule haven’t yet been determined, NASA plans to do so within the coming weeks.
The schedule change means that the return of ISS expedition 43 crewmembers Terry Virts, Samantha Cristoforetti and Anton Shkaplerov will be delayed until at least early June.
Roscosmos continues its investigation of the Progress mishap and is expected to provide an update on Friday, May 22.
I love to read your thoughts & really admire your views.
