Jay Stratton : first look inside my book

Approximately 13.8 billion years ago, the Big Bang is hypothesized to have occurred, kickstarting our universe and eventually life on our small, blue world. While the Big Bang has yet to be directly observed, scientists have worked tirelessly to piece together the events that happened immediately after the Big Bang, specifically the first billion years or less, with the goal of gaining insight into the how the first stars, and potentially planets, formed and evolved.

Students in Cornell’s Space Systems Design Studio have published results from two lightsail experiments (Alpha CubeSat and Sailing to the Stars) built by engineering students at Cornell University.

Galaxies are like snowflakes, no two exactly alike, even the spirals. The Hubble Space Telescope did a visual dive into the distant spiral NGC 4693 and found some intriguing hints to its past. For one thing, this member of the Virgo Cluster seems to have a central region that's rotating out of sync with the spiral arms and bulge. Those arms don't seem to connect to the central region, and the bulge itself seems to extend out above the plane of the galaxy.

Teaching my 3 month old son some UFO history 😂

SpaceX sent its Starship super-rocket on its first orbital flight — a shorter-than-planned test mission that put operational Starlink satellites into orbit for the first time.

The Canadian Hydrogen Intensity Mapping Experiment (CHIME) has shown for the first time that it can detect the faint glow of hydrogen gas from deep in the universe's past using only its own data.

Researchers have discovered a novel way of making chaotic light, sound, and other kinds of waves follow stable pathways.

Something deep inside Mars has scientists looking for clues to its internal evolution. A team at the University of Arizona led by Alexander Byrne, used a technique called "tidal tomography" to probe a heat anomaly in the southern hemisphere mantle. It turns out this subsurface region measures about 200 to 400 degrees Celsius warmer than the rest of the mantle. That warm spot may contain information about how Mars has changed over its lifetime.

Researchers at The University of Texas at Austin have rewritten a small part of Oklahoma's geologic history with global implications for ancient life. Below the surface of the small town of Ames, Oklahoma, a meteor impact site spans miles. The crater is buried by sedimentary strata in the subsurface, but it remains an important marker of Oklahoma's ancient past and present-day economy; the Ames impact structure is a major oil and gas producer.

A recent discovery at Turkey’s famous Göbekli Tepe is offering new clues about the enigmatic ancient site’s purpose.

Both stellar-mass black holes and supermassive black holes can produce ionized jets streaming from their poles. Stellar-mass black holes consume the material of companion stars, while supermassive black holes rip stars apart in tidal disruption events. Despite these different eating habits, the formation of jets requires similar conditions.

Way back in the earliest epochs of the Universe, the Big Bang was followed by a period called the Cosmic Dark Ages. It was a time when the cosmic soup of primordial particles was so thick that light couldn't propagate. Hence the term "dark"; also, because, even with our best telescopes, we can't see "into" that epoch. Although we don't have a definite "century by century" timeline of activity, that doesn't mean that period of history didn't lead to something interesting.

Christian-faith scientists and Turkish archaeologists have completed core drilling excavations at the controversial 'Noah's Ark' site.

Astronomers have cataloged billions of stars and hundreds of billions of galaxies. We have found thousands of planets orbiting stars. We can also map where galaxies sit and trace how the universe changes over time.

Background Before the modern era, cryptography was concerned solely with message confidentiality (i.e., encryption)—conversion of messages from a comprehensible form into an incomprehensible one and back again at the other end, rendering it unreadable by interceptors or eavesdroppers without secret knowledge (namely the key needed for decryption of that message). Encryption attempted to ensure secrecy [...] The post FBI Files on Cryptography – FBI File #80-HQ-612 first appeared on The Black Vault.
