Fluorescent Oil Swirls Over An Experimental Aircraft

When NASA Langley Research Center engineers wanted to put one of their aircraft models through a wind tunnel test, they needed a way to visualize how wind flowed over the design. So they sprayed fluorescent oil onto the model, which is 5.8 percent of the final craft's size. You can see the results here. The tests took place at Langley Research Center's Subsonic Wind Tunnel, which is used for testing aircraft that can take off and land without long runways. The tunnel works well for testing stability, aerodynamics, acoustics and basic airflow, according a NASA description.

Detectan ‘nave espacial’ en la Luna a través de Google Moon

Los sitios web de ufología insinúan que se trataría de una nave espacial o una base extraterrestre

Un usuario del servicio de mapas lunares de Google detectó en la superficie del satélite natural un objeto triangular que parece tener filas de luces. Los sitios web de ufología insinúan que se trataría de una nave espacial o una base extraterrestre, informó el portal RT. El enigmático triángulo de doble cara, que parece tener unas filas de siete puntos de luz en sus costados, fue descubierto por un investigador de casos paranormales apodado ‘WowForReeel’, que lo publicó en un video de su canal deYouTube, indicó Dailymail. “¿Es simplemente un cráter de aspecto extraño o es algo más?”, pregunta el usuario. “Realmente está allí, no es un montaje y no tengo ni idea de lo que es”, concluyó. Sin embargo, ante la aparición de este enigmático objeto triangular, localizado gracias al servicio de exploración lunar virtual de Google, muchos aficionados a la ufología indican que podría tratarse de una base alienígena situada bajo el polvo de la Luna, aunque algunos incluso afirman que sería una construcción humana. Además, según un sitio web sobre ovnis el cuestionable descubrimiento no sería sino “una inmensa nave espacial triangular”, que atestigua la existencia de una tecnología secreta de construcción de aviones furtivos, pero “su tamaño es considerablemente más grande que el de cualquier nave construida en la Tierra”. Hasta la fecha ni los satélites ni los ‘rovers’ de exploración han descubierto en la Luna ni en ningún otro planeta observado ningún elemento parecido a este objeto, asevera el portal, cuyos autores también llegaron a suponer, debido a las impresionantes dimensiones del hallazgo, que se trata de “una especie de base lunar utilizada como instalación para el almacenamiento y el lanzamiento de naves espaciales extraterrestres”

Supersonic Travel: Would you like to get to Sydney, Australia in 4 hours?

While supersonic planes haven’t been available to commercial travelers since 2003, speed freaks can revel in the fact that several new supersonic planes are currently in development.Boeing, Gulfstream and NASA are collaborating on a plane nicknamed the “Son of Concorde,” which would be capable of flying around 2,500 miles per hour. That’s almost twice the speed of the original Concorde, and means a trip from London to Sydney, Australia, would only take four hours, about a fifth of the time it currently takes. The jet would use lighter materials, state of the art engines and a redesigned fuselage to attain the fast speeds.Separately, the Aerion Corporation is working on a new 12-passenger supersonic business jet that would fly at about Mach 1.6, or about 1,200 mph. That’s almost twice as fast as the top speed of a Boeing 747, which is around 650 mph. So a flight from New York to Paris would take about 4 hours and 15 minutes – three hours shorter than current subsonic travel times. The challenge with any new supersonic plane is reducing noise from sonic booms – the loud bangs made by a supersonic plane’s sound waves. Commercial supersonic planes are banned from flying over land in many places because the sonic booms are so distracting to the people below. Researchers at NASA are experimenting with various plane shapes to find the quietest option, which may include a longer, more pointed fuselage than the Concorde had. The need for continued research means supersonic planes won’t be carrying passengers until the start of the next decade, at the earliest. But if it means you can get from London to Sydney in four hours, it will be worth the wait.

A newly translated Hebrew text claims to reveal where treasures from King Solomon's temple

A newly translated Hebrew text claims to reveal where treasures from King Solomon's temple were hidden and discusses the fate of the Ark of the Covenant itself. But unlike the Indiana Jones movie "Raiders of the Lost Ark," the text leaves the exact location of the Ark unclear and states that it, and the other treasures, "shall not be revealed until the day of the coming of the Messiah son of David …" putting it out of reach of any would-be treasure seeker. King Solomon's Temple, also called the First Temple, was plundered and torched by the Babylonian King Nebuchadnezzar II in the sixth century B.C., according to the Hebrew Bible. The Ark of the Covenant is a chest that, when originally built, was said to have held tablets containing the 10 commandments. It was housed in Solomon's Temple, a place that contained many different treasures. The newly translated text, called "Treatise of the Vessels" (Massekhet Kelim in Hebrew), says the "treasures were concealed by a number of Levites and prophets," writes James Davila, a professor at the University of St. Andrews, in an article in the book "Old Testament Pseudepigrapha More Noncanonical Scriptures Volume 1" (William B. Eerdmans Publishing Co., 2013). "Some of these (treasures) were hidden in various locations in the Land of Israel and in Babylonia, while others were delivered into the hands of the angels Shamshiel, Michael, Gabriel and perhaps Sariel …" writes Davila in his article. The treatise is similar in some ways to the metallic "Copper Scroll," one of the Dead Sea Scrolls found near the site of Qumran in the West Bank. The Copper Scroll also discusses the location of hidden treasure, although not from Solomon's Temple. The treatise describes the treasures in an imaginative way. One part refers to "seventy-seven tables of gold, and their gold was from the walls of the Garden of Eden that was revealed to Solomon, and they radiated like the radiance of the sun and moon, which radiate at the height of the world." The oldest confirmed example of the treatise, which survives to present day, is from a book published in Amsterdam in 1648 called "Emek Halachah." In 1876, a scholar named Adolph Jellinek published another copy of the text, which was virtually identical to the 1648 version. Davila is the first to translate the text fully into English. A story of legends The writer of the text likely was not trying to convey factual locations of the hidden treasures of Solomon's Temple, but rather was writing a work of fiction, based on different legends, Davila told LiveScience. "The writer draws on traditional methods of scriptural exegesis [interpretation] to deduce where the treasures might have been hidden, but I think the writer was approaching the story as a piece of entertaining fiction, not any kind of real guide for finding the lost Temple treasures," he wrote in the email. The Treatise of the Vessels (Massekhet Kelim) is recorded in the 1648 Hebrew book Emek Halachah, pub … The structure of the story is confusing. In the prologue it states that Shimmur the Levite (he doesn't appear to be a biblical figure) and his companions hid the treasures, "but later on the text mentions the treasures being in the keeping of or hidden by Shamshiel and other angels," Davila said. "I suspect the author collected various legends without too much concern about making them consistent." Similarities to the Copper Scroll The Copper Scroll, which dates back around 1,900 years, and is made of copper, shows several "striking parallels" with the newly translated treatise, Davila said. The treatise says that the treasures from Solomon's Temple were recorded "on a tablet of bronze," a metal like the Copper Scroll. Additionally, among other similarities, the Treatise of the Vessels and Copper Scroll both refer to "vessels" or "implements," including examples made of gold and silver. These similarities could be a coincidence or part of a tradition of recording important information on metal. "My guess is that whoever wrote the Treatise of Vessels came up with the same idea [of writing a treasure list on metal] coincidentally on their own, although it is not unthinkable that the writer knew of some ancient tradition or custom about inscribing important information on metal," wrote Davila in the email, noting that metal is a more durable material than parchment or papyrus. An ongoing story The study of the treatise is ongoing, and discoveries continue to be made. For instance, in the mid-20th century a copy of it (with some variations) was discovered and recorded in Beirut, Lebanon, at the end of a series of inscribed plates that record the Book of Ezekiel. Those plates are now at the Yad Ben Zvi Institute in Israel, although the plates containing the treatise itself are now missing. Recent research has revealed, however, these plates were created in Syria at the turn of the 20th century, about 100 years ago, suggesting the treatise was being told in an elaborate way up until relatively modern times.
