Why the Moon is Still Unexplored | Unveiled
In this video, Unveiled asks; why is there STILL so much mystery surrounding the moon?? Are you constantly curious? Then subscribe for more from Unveiled ► https://wmojo.com/unveiled-subscribe It has been almost 50 years since a human being stepped foot on the moon. After the rush at the end of the 1960s, NASA's Apollo program was quickly cancelled... But WHY?? Yes, we've taken photos from far off satellites, but we haven't explored the lunar surface in detail. That's all about to change... This is Unveiled, giving you incredible answers to extraordinary questions! Find more amazing videos for your curiosity here:

Dwarf Planets | The Ice Worlds
The Solar System is home to eight main planets, but this is far from the full picture. Hidden beyond the orbit of Neptune are dozens of small, icy worlds, known as Dwarf Planets, or Minor Planets! The best example is Pluto, but there are dozens more orbiting within the same band of material at the outer Solar System. Today, we will visit these frozen, far out worlds first hand.

What Would an Alien Megastructure Look Like? Ringworlds with Larry Niven and Gregory Benford
From both Gregory Benford and Larry Niven comes a thrilling, hard science fiction series, Bowl of Heaven, that follows a human expedition to another star system that’s suddenly interrupted by a gigantic artifact floating in interstellar space. The bowl-shaped structure engulfs an entire star, and has a habitable area equivalent to many millions of Earths. Gregory Benford is a physicist, educator, and award winning author. Larry Niven is an award winning author, best known for his book Ringworld. Link:

Alien Biosphere Evolution #8: The Arthropod Recipe
Arthropods are about as alien to us as another highly evolved bilateral animal can be. That’s undoubtedly the reason why their looks and features are often adopted into science fiction for creating odd-looking extraterrestrial beings. Despite their humble body sizes, arthropods have been extremely successful in populating our biosphere. So given the enormous success of this particular body plan, it's likely that alternate "arthropoids" or "arthropodoids" could enjoy the same success in alien biospheres. It would be a very interesting exercise in speculative zoology to design and tweak such “alternate arthropods” to evolve in different ways. But before we do that, we need to know how our won arthropods, like insects, crustaceans, chelicerates (spiders and scorpions), myriapods and others evolved. It all goes back to the Cambrian Explosion where weird life forms like Anomalocaris and Hallucigenia, but also Priapulids, hold the key to understanding the genesis of this major phylum. So how could these life forms evolve elsewhere? Let’s find out! Website: https://www.phrenotopia.com/

Can We Put a Radio Telescope on the Far Side of the Moon? With Saptarshi Bandyopadhyay
An ultra-long-wavelength radio telescope on the far-side of the Moon has tremendous advantages compared to Earth-based and Earth-orbiting telescopes, particularly a Lunar Crater telescope can observe the universe at wavelengths greater than 10m (i.e., frequencies below 30MHz), which are reflected by the Earth’s ionosphere and are hitherto largely unexplored by humans. John Michael Godier speaks with Saptarshi Bandyopadhyay about his 2020 NIAC finalist project for putting a radio telescope inside a crater on the far side of the moon. Link:

Interstellar Trade & Cyclers
Get a free month of Curiosity Stream: https://curiositystream.com/isaacarthur
Establishing Interstellar Trade and Commerce in the future will require an entirely new approach to moving cargo, as years if not centuries might pass for shipments to arrive by even the fastest spaceships, but may be aided by the use of vast interstellar Cycler Castles traveling on century long trade routes.

The Way of the Wormhole | Juan Maldacena
Einstein's theory of general relativity predicted the warping of spacetime due to gravitational forces. When this bending becomes so strong that a region of space folds like a piece of paper, the hypothetical tunnels known as wormholes can be formed. The extreme gravitational conditions necessary for this to happen may occur around supermassive black holes. But do wormholes really exist? And if so, how can we find them? When taken to the extreme, gravity can create some intriguing visual effects known as gravitational lensing, that can be observed through telescopes. From the outside, wormholes can appear similar to black holes, but while moving in front of a distant star, a wormhole big enough to fit a spaceship would create a very specific type of this weird laughing mirror effect. Therefore, when it comes to hunting wormholes, looking for the distant signatures of smaller gravity lenses known as micro lenses could be the way to go. Just as optical telescopes collect visible light, so do radio telescopes collect the radio waves emitted by stars, galaxies, black holes and perhaps wormholes. Investigating ways to distinguish a wormhole from a black hole, researchers have focused on supermassive black holes with masses millions to billions of times that of the sun, which are thought to dwell at the hearts of most, if not all, galaxies. For example, at the center of our Milky Way galaxy lies Sagittarius A, a monster black hole that is about 4.5 million solar masses in size. What if such an “active galactic nucleus” (AGN) were a wormhole mouth rather than a supermassive black hole? Any matter falling into the mouth of a supermassive wormhole would likely travel at extraordinarily high speeds due to its powerful gravitational fields. The collision in the wormhole's throat of matter flowing through both mouths would result in spheres of plasma expanding from the wormhole at nearly the speed of light. Those spheres can reach temperatures of about 10 trillion degrees Celsius and would produce gamma rays with extremely high energies. In contrast, accretion disks of AGNs are too cold to emit gamma radiation. Moreover, although jets from AGNs can emit gamma rays, they would mostly travel in the same direction as the jets — any traveling out in a sphere might suggest they came from a wormhole. All in all, there are several ways in which the gamma radiation emitted by wormholes has a distinctive spectrum much different from those of supermassive black holes. An observation of such radiation would serve as convincing evidence of their existence. Researchers have also considered the possibility that wormholes can act as natural particle accelerators. The high-energy cosmic rays produced by such a scheme could be detected by sensitive radio telescopes as well. It is thought that this phenomenon may occur when a wormhole generates and maintains a magnetic field, which might also explain the observation of such fields in cosmic voids. In addition to telescopes, gravitational wave detectors could be used to detect wormholes in deep space. The United States–based Advanced LIGO, or Laser Interferometer Gravitational-Wave Observatory, as well as the Advanced Virgo detector near Pisa, Italy, have already detected ripples in spacetime caused by the merging of two black holes or dense stellar corpses called neutron stars. But scientists have also considered a black hole with a mass five times the sun’s, orbiting a wormhole billions of light years from Earth. As the black hole swings around the wormhole, the researchers calculated, it would begin to spiral inward as if it were orbiting another black hole. Initially, the resulting gravitational waves would look like a standard signature for two black holes, a pattern of waves that increase in frequency over time called a chirp.

How to Communicate with Europa featuring Dr. Robert Romanofsky of NASA
Magneto-Inductive Communications for Ocean Worlds, is a new concept from Dr. Robert Romanofsky of NASA. A mission to the under-ice ocean of Europa is one of the highest priority missions for NASA. Dr. Romanofsky's concept is for a probe to melt through the 5 to 10 km thickness of briny ice to reach the buried ocean below. The challenge of communicating back to the surface of Europa is also directly addressed. Link:
