How pristine Ultima Thule is — New Horizons mission scientists have released the first peer-reviewed results from their study of 2014 MU69, demonstrating just how “pristine” this object is. Around 16kms across, it orbits the Sun at a distance of around 6.5 billion km (Pluto orbits at around 5.9 billion km). It seems to have remained relatively unaltered from the solar system’s earliest era, and it already presented some surprises when the New Horizon spacecraft transmitted its first images back — and now, those first results are published and vetted.
But things are just getting started for this team.
~ Never have ‘coalescing pebbles’ seemed so interesting.
Lopsided Moon — Our Moon features a nearside and far side with dramatically different geological features. This anomaly has puzzled scientists for years, but new computer simulations suggest the Moon’s asymmetric disposition can be traced back to an ancient collision with another object – possibly a dwarf planet.
~ The far side crust was about 10 kilometres thicker than the crust on the near side.
Student rocket reaches space — The USC team’s successful launch represents one of several groups of college students across the United States and Europe that have been racing to send a rocket above the Kármán line, the imaginary boundary that separates Earth’s atmosphere and space.
~ The collegial space race.
Room-temp superconductor — A team of physicists has published peer-reviewed results documenting near-room-temperature superconductivity in the hydrogen-rich compound lanthanum hydride.
~ That means power savings, and lower AC costs.
Near-room-temp superconductor — In the most recent paper, researchers placed a piece of lanthanum into an insulating ring, then placed it into a box full of pressurised hydrogen gas.
~ Damn, I was going to do that.
American Civil War medicinal plants — With conventional medicines in short supply during the Civil War, the Confederacy turned to plant-based alternatives in desperation. New research suggests some of these remedies were actually quite good at fighting off infections – a finding that could lead to effective new drugs.
~ This from an amazingly thorough compendium first published in 1863.
Trees are connected underground — Millions of species of fungi and bacteria swap nutrients between soil and the roots of trees, forming a vast, interconnected web of organisms throughout the woods. Scientists have now mapped this ‘wood wide web‘ on a global scale, using a database of more than 28,000 tree species in over 70 countries.
~ More complexities to discover.
