The Inspirational Impact of Space on The Global Civilization

Malak Trabelsi Loeb

The present generation has witnessed a rare phenomenon during one’s life: the rise of a new civilization. Fueled by the global-minded elite who influenced and controlled the comprehensive economic policies and strategies, a new wave of globalization has emerged. Targowski (2014) defined “global civilization” as the following:

“Global Civilization is a large Global Society living in integrated horizontally whole or partial spaces of contemporary, autonomous civilizations as a fuzzy reification (invisible-visible) which is not a part of the larger one and exists over an extended period of time.”

For Targowski, this new global civilization is characterized by an advanced global culture, a “wealth and power-driven global business religion,” and global societal values based on shared knowledge systems.

Hubble Eyes a Colorful Pocket of Stars – Orbiting Closely, Like Bees Swarming Around a Hive

Many colorful stars are packed close together in this image of the globular cluster NGC 1805, taken by the NASA /ESA Hubble Space Telescope. This tight grouping of thousands of stars is located near the edge of the Large Magellanic Cloud, a satellite galaxy of our own Milky Way. The stars orbit closely to one another, like bees swarming around a hive. In the dense center of one of these clusters, stars are 100 to 1000 times closer together than the nearest stars are to our Sun, making planetary systems around them unlikely.

The striking difference in star colors is illustrated beautifully in this image, which combines two different types of light: blue stars, shining brightest in near-ultraviolet light, and red stars, illuminated in red and near-infrared. Space telescopes like Hubble can observe in the ultraviolet because they are positioned above Earth’s atmosphere, which absorbs most of this wavelength, making it inaccessible to ground-based facilities.

This young globular cluster can be seen from the southern hemisphere, in the Dorado constellation, which is Portugese for dolphinfish. Usually, globular clusters contain stars which are born at the same time; however, NGC 1805 is unusual as it appears to host two different populations of stars with ages millions of years apart. Observing such clusters of stars can help astronomers understand how stars evolve, and what factors determine whether they end their lives as white dwarfs, or explode as supernovae.

Earth Should Be Dry – An Unexpected Meteorite Discovery Reveals the Origin of Earth’s Vast Oceans

Meteorite material presumed to be devoid of water because it formed in the dry inner Solar System appears to have contained sufficient hydrogen to have delivered to Earth at least three times the mass of water in its oceans, a new study shows.

While the idea that enstatite chondrite (EC) meteorites contained enough hydrogen to provide water to the growing proto-Earth has been proposed, efforts to rigorously test this scenario have been hampered by difficulties in measuring hydrogen concentrations in ECs — an obstacle this study overcame.

According to models of Solar System formation, Earth should be dry. However, our blue planet’s vast oceans, humid atmosphere and well-hydrated geology boldly defy such predictions, making it unique among the other rocky planets of the inner Solar System.

Unexpected Electrical Current Discovered That Could Stabilize Fusion Reactions – Bringing the Fusion Energy That Drives the Sun to Earth

Electric current is everywhere, from powering homes to controlling the plasma that fuels fusion reactions to possibly giving rise to vast cosmic magnetic fields. Now, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have found that electrical currents can form in ways not known before. The novel findings could give researchers greater ability to bring the fusion energy that drives the sun and stars to Earth.

“It’s very important to understand which processes produce electrical currents in plasma and which phenomena could interfere with them,” said Ian Ochs, graduate student in Princeton Universitys Program in Plasma Physics and lead author of a paper selected as a featured article in Physics of Plasmas. “They are the primary tool we use to control plasma in magnetic fusion research.”

Episode 14 — Does the Dwarf Planet Ceres Harbor Life?

Please have a listen to Episode 14 of Cosmic Controversy with guest Julie Castillo, NASA’s Dawn mission project scientist. We spend much of the episode discussing the beguiling dwarf planet Ceres and the need for a sample return mission.

This week’s guest is NASA Dawn project scientist Julie Castillo-Rogez who led the hugely successful robotic mission on the first in-depth look at the asteroid Vesta and the dwarf planet Ceres. Castillo talks about why there’s a growing consensus that Ceres may have long had habitable subsurface conditions and why we need a sample return mission to launch in 2033. We also discuss Mars’ moons of Deimos and Phobos and the first interstellar asteroid, Oumuamua.

The moon is rusty, and it’s likely Earth’s fault

The moon is turning ever so slightly red, and it’s likely Earth’s fault. Our planet’s atmosphere may be causing the moon to rust, new research finds.

Rust, also known as an iron oxide, is a reddish compound that forms when iron is exposed to water and oxygen. Rust is the result of a common chemical reaction for nails, gates, the Grand Canyon’s red rocks — and even Mars. The Red Planet is nicknamed after its reddish hue that comes from the rust it acquired long ago when iron on its surface combined with oxygen and water, according to a statement from NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.
