NASA Scientists Find Sun’s History Buried in Moon’s Crust

NASA Scientists Find Sun’s History Buried in Moon’s Crust

The Sun is why we’re here. It’s also why Martians or Venusians are not. The Sun’s rotation rate in its first billion years is unknown. Yet, this spin rate affected solar eruptions, influencing the evolution of life. A team of NASA scientists think they’ve figured it out by using the Moon as critical evidence.

How we discovered 840 minor planets beyond Neptune – and what they can tell us

How we discovered 840 minor planets beyond Neptune – and what they can tell us

Our solar system is a tiny but wonderfully familiar corner of the vast, dark universe – we have even been able to land spacecraft on our celestial neighbours. Yet its outer reaches are still remarkably unmapped. Now we have discovered 840 small worlds in the distant and hard-to-explore region beyond Neptune. This is the largest set of discoveries ever made, increasing the number of distant objects with well known paths around the sun by 50%.

How comet dust has allowed us to trace the history of the Solar System

How comet dust has allowed us to trace the history of the Solar System

We are not used to considering dust as a valuable material – unless it comes from space. And more precisely, from the comet 67P/Churyumov-Gerasimenko. An analysis of its dust has provided valuable information about this celestial object, and, more generally, on the history of the Solar System.
