For the 1st time, scientists confirm the moon has a solid iron 'heart' just like Earth

After more than 50 years, scientists finally confirmed that the moon has a solid inner core, just like Earth.

I don't buy it. I'm not saying the moon is hollow, but I think it's less dense the deeper you go. When they experimented back in the 70s they discovered that vibrations sped up as they got deeper, not slowed down.

Yes, I don’t believe that the moon has a dense core.

It took three separate waves of modern humans to colonise Europe between 54,000 and 42,000 years ago. That is the key conclusion of scientists who have been studying caves in the Rhone valley where they have discovered evidence that Homo sapiens had to make a trio of determined attempts to head westwards and northwards from western Asia before they could establish themselves in the continent.

“The first two of these waves failed but the third succeeded around 42,000 years ago,” said Ludovic Slimak of the University of Toulouse, who is leading the excavations in France. “After that, modern humans took over in Europe. The Neanderthals, who had evolved on the continent, died out.”

The group’s research, published in the journal Plos One, is controversial because it implies that our species settling in Europe took around 12,000 years to complete. Far from being a rapid takeover, modern humans’ transition into the continent was a lengthy affair involving travel along the Mediterranean before our ancestors headed northwards up the Rhone valley…….

Frogs in Puerto Rico are croaking at a higher pitch due to global heating, scientists have found.

The frogs appear to be decreasing in size at warmer temperatures, which causes their croaks to become high pitched. If the trends continue, the heat could become too much for the sensitive amphibians to survive successfully, researchers have said.

The call of the coquí frog is well known to most who have spent time in Puerto Rico. It is named for its two-note call “co-qui”, which rings out throughout the island every night……

What time is it on the moon? How a lunar clock debate led to an out-of-this-world timepiece

Unfortunately, the unique timepiece was looked upon more as a novelty as opposed to a useful scientific device.

www.space.com

Back in November, a gathering of members from space organizations around the world met in the Netherlands and agreed that there is going to be a need to implement a proper lunar time zone — an internationally accepted common lunar reference time that all future missions can use to communicate and navigate with ease. "A new era of lunar exploration is on the rise, with dozens of moon missions planned for the coming decade," said Jörg Hahn, an advisor from the European Space Agency (ESA) for the lunar timekeeping project.
