Lights in the Dark 2 Jul 2020, 18:23 UTC Our beautiful Moon, serenely circling our world as it illuminates our evenings and tugs at our tides, is thought to have been born from a violent and catastrophic collision between a freshly-formed Earth and a Mars-sized wayward protoplanet almost four and a half billion years ago. This “giant impact hypothesis” is generally accepted because it provides causation for many aspects of why the Moon is how we see it today. But there have always been some discrepancies with the theory—one of which being the difference in distribution and amount of some heavy metals in the Moon’s composition based on when the impact event occurred during Earth’s formative years.
First Exposed Planetary Core Discovered – An Extremely Unusual Planet in the So-Called “Neptune Desert”2 Jul 2020, 08:38 UTC The newly discovered Neptune-sized exoplanet TOI 849 b orbits its star in just 18 hours and offers a unique opportunity to peer inside a planet to investigate how planets form. Was it like Jupiter before its atmosphere was stripped or did it fail to form one in the first place?
Universe Today 1 Jul 2020, 04:08 UTC When NASA’s new Perseverance Martian rover launches in a little over a month it will have a small robotic stow-away on board. Ingenuity is a small helicopter, with a fuselage about the size of a softball and two extending rotors that measure about 4 feet across. It was attached to the bottom of the rover’s chassis in April, and NASA recently released details about it’s technically challenging release process.
