aFor thousands of years, people have used stars as a means of navigating. They have also fostered some of our most common myths. Astronomers have created 88 groupings of stars and galaxies into what are called constellations. Learning the constellations is very interesting especially for anyone ...

Directional symmetry:Some symmetry is across time, where we naturally expect something that rises to fall, at least in the short term. A musical sequence that escalates must come back and resolve itself toward some center (called the root). Market trends like recessions and bubbles are also sy...
starlight can easily pass through the clear air and be absorbed only by the specific gases in that part of the atmosphere,” Brande said. “However, if the cloud is positioned very high, clouds are generally opaque across the electromagnetic spectrum. While hazes have spectral...
Ancient Greeks are among the first to have recorded constellations — one of our earliest attempts at making sense of the cosmos. But our obsession with the stars began earlier than that, some 7,000 years ago when a group of nomadic hunter-gatherers in Africa built stone circles which tracked...

Expert RAW gave Shainblum the flexibility he needed to customise his settings and really make the stars shine. Using the app’s Astrophoto feature⁷, he was able to see a detailed map of the night sky featuring the names of the stars, constellations and planets in his shot. “The Astro...
However, intentional, nefarious threats from other nations are not the only concern for the U.S. Space Force and other countries' growing military space efforts. Constellations of satellites from private companies here on Earth can also pose serious issues. The "proliferation in low Earth orbit of...
