Circumplanetary Disk
Young planet designated PDS 70 c has a circumplanetary disk, a feature that is strongly theorized to be the birthplace of moons, credit to ALMA (ESO/NAOJ/NRAO) A. Isella; ESO.
This is a composite image of the young star system PDS 70. Comparing new ALMA data to earlier VLT observations, astronomers determined that the young planet designated PDS 70 c has a circumplanetary disk, a feature that is strongly theorized to be the birthplace of moons, credit to ALMA (ESO/NAOJ/NRAO) A. Isella; ESO.

 

Solar System Formation, Planets & Moons

'Moon-Forming' Circumplanetary Disk Discovered in Distant Star System,
National Radio Astronomy Observatory, July 11. 2019.

MAIN POINTS

Distant Moon Formation
"...made the first-ever observations of a circumplanetary disk, the planet-girding belt of dust and gas that astronomers strongly theorize controls the formation of planets and gives rise to an entire system of moons, like those found around Jupiter."

ASTRONOMY, PHYSICS 


Really Big and Really Small Scale Sciences

The Fundamental Nature of Reality Big to Small... 

We follow Astro-physics and Science News for fun, because the Nature of Life itself is pretty darn entertaining on its own merits. Understanding the Nature and construction of our reality is a pragmatic move for all its "operators," but especially for backpacker's finding context in, and navigating the terrain to both ascertain & clarify our place in the Universe.

This is the amazing universe we are walking through.

Interestingly enough, we have to understand the fundamental nature of the motions & relationships within the Universe around us to find our precise position on this Earth, to understand our context within its Nature, and how we can or cannot fit perfectly into the greater Universe around us.

We follow science to better understand ourselves, what we are hiking through, and our choices along our journey.

CNRS, July 30, 2018.

MAIN POINTS

What
"Sagittarius A* (Sgr A* Black Hole) sits at the centre of our galaxy, 26,000 light-years from Earth. This black hole, which has a mass 4 million times that of the sun, is surrounded by a star cluster - the S stars - which reach mind-boggling speeds when they approach the hole."

"...to follow one particular star in the Sgr A* system - S2 - before and after it passed close to the black hole on 19 May 2018. GRAVITY achieved a resolution of 50 microarcseconds: the angle at which a tennis ball placed on the moon would be visible from Earth."

11 Year Sun Cycle Explained by Orbital Cycle of Alignments

The Sun Follows the Rhythm of the Planets,
Helmholtz-Zentrum Dresden-Rossendorf, May 27, 2019.

MAIN POINTS

11 Year Solar Cycle
"...the tidal forces of Venus, Earth and Jupiter influence the solar magnetic field, thus governing the solar cycle."

Elusive Cycle
"...past models have been unable to adequately explain the very regular cycle of the sun."

How Cause was Found
"...systematically compared historical observations of solar activity from the last thousand years with planetary constellations, statistically proving that the two phenomena are linked."

"There is an astonishingly high level of concordance: what we see is complete parallelism with the planets over the course of 90 cycles."

Supernova Cosmic Radiation sets Forest Fires that Evolved Footloose Humans?

Researchers wonder if Ancient Supernovae prompted Human Ancestors to Walk Upright,
University of Kansas, May 28, 2019.

MAIN POINTS

Hella Light Show
"Supernovae bombarded Earth with cosmic energy starting as many as 8 million years ago, with a peak some 2.6 million years ago, initiating an avalanche of electrons in the lower atmosphere and setting off a chain of events that feasibly ended with bipedal hominins such as homo habilis, dubbed "handy man."

Building Blocks of Life on Titan

Researchers find ice feature on Saturn's giant moon,
University of Arizona, April 29, 2019.

MAIN POINTS

Methane
"Rain, seas and a surface of eroding organic material can be found both on Earth and on Saturn's largest moon, Titan. However, on Titan it is methane, not water, that fills the lakes with slushy raindrops."

"There is no obvious source of methane..."

"...also indicates a diversity of organic material in certain regions. These surface deposits are of interest because laboratory simulations of Titan's atmosphere produce biologically interesting compounds such as amino acids."

ASTROPHYSICS

Artistic Impression of V404 Cygni Black Hole Sloppily Eating a Giant Star, ICRAR.
"The binary star system consists of a normal (reddish giant) star in orbit with a black hole. Material from the star falls towards the black hole and spirals inwards in an accretion disk, with powerful jets being launched from the inner regions close to the black hole. The key deal here is the rotation of the jet." By the International Centre for Radio Astronomy Research, ICRAR.

Messy Explanation of the Messy Formation of the Moon

Magma is the Key to the Moon's Makeup,
Yale University, April 29, 2019.

Main Points

The Key
Who's Key?
"....is that the early, proto-Earth -- about 50 million years after the formation of the Sun -- was covered by a sea of hot magma, while the impacting object was likely made of solid material."

Modeling
"...set out to test a new model, based on the collision of a proto-Earth covered with an ocean of magma and a solid impacting object."
