UFOs
Explores some of the most popular UFO sightings of the past century, offers explanations, and discusses their impact on society.
The UFO Files
'What does all this stuff about flying saucers amount to? What can it mean? What is the truth?' Winston Churchill, prime minister's personal minute, 28th July 1952 The UFO Files tells the story of over 100 years of UFO sightings, drawing on formerly secret government documents at the National Archives in London. Alongside extraordinary reports by ordinary people, it reveals details of official interest and investigations stretching back more than 80 years. In this remarkable book, fully updated for this second edition, David Clarke reveals an array of startling stories from possible UFO reports hidden among Met Office investigations of aerial phenomena in the 1920s to the conclusions of Project Condign, the secret British Intelligence UFO study completed in 2000. As well as covering Roswell and Britain's own Rendlesham Forest mystery, Clarke raids the records for dramatic stories of abductions and close encounters, ghost aircraft and crop circles, and UFO reports by both civilian aircrew and military personnel. Dramatic witness statements and interviews combine with rarely seen photographs, drawings and newly available documents to offer a unique guide to one of our most intriguing mysteries.
The form development in the Kazan State Circus architecture
The Kazan State Circus was built in 1965-1967, its shape was very unusual for that time and resembled a disk. Many researchers considered that the creators of the Kazan Circus borrowed its forms directly from the works of foreign architects of the modernist era, such as P.L. Nervi or O. Niemeyer. However, with a detailed comparison, it can be concluded that such a statement only partially corresponds to reality. The main purpose of this work is to search for the initial forms that became the basis for the design of the Kazan Circus building. This article presents the idea of the influence of the cult of unidentified flying objects (UFOs), which arose from the late 40s of the 20th century in the USA, including with the filing of George Adamski, who allegedly saw UFOs in the form of a disk in the sky several times. The article also examines the influence of Eastern philosophical and religious trends of the Buddhism and Hinduism on the architectural forms of the Kazan circus. The shaping of the Kazan Circus was subsequently used by other architects in the construction of various objects, for example, the Krasnodar Circus (Russia) and Astana Circus (Kazakhstan).
Commissioning an All-Sky Infrared Camera Array for Detection of Airborne Objects
To date, there is little publicly available scientific data on unidentified aerial phenomena (UAP) whose properties and kinematics purportedly reside outside the performance envelope of known phenomena. To address this deficiency, the Galileo Project is designing, building, and commissioning a multi-modal, multi-spectral ground-based observatory to continuously monitor the sky and collect data for UAP studies via a rigorous long-term aerial census of all aerial phenomena, including natural and human-made. One of the key instruments is an all-sky infrared camera array using eight uncooled long-wave-infrared FLIR Boson 640 cameras. In addition to performing intrinsic and thermal calibrations, we implement a novel extrinsic calibration method using airplane positions from Automatic Dependent Surveillance–Broadcast (ADS-B) data that we collect synchronously on site. Using a You Only Look Once (YOLO) machine learning model for object detection and the Simple Online and Realtime Tracking (SORT) algorithm for trajectory reconstruction, we establish a first baseline for the performance of the system over five months of field operation. Using an automatically generated real-world dataset derived from ADS-B data, a dataset of synthetic 3D trajectories, and a hand-labeled real-world dataset, we find an acceptance rate (fraction of in-range airplanes passing through the effective field of view of at least one camera that are recorded) of 41% for ADS-B-equipped aircraft, and a mean frame-by-frame aircraft detection efficiency (fraction of recorded airplanes in individual frames which are successfully detected) of 36%. The detection efficiency is heavily dependent on weather conditions, range, and aircraft size. Approximately 500,000 trajectories of various aerial objects are reconstructed from this five-month commissioning period. These trajectories are analyzed with a toy outlier search focused on the large sinuosity of apparent 2D reconstructed object trajectories. About 16% of the trajectories are flagged as outliers and manually examined in the IR images. From these ∼80,000 outliers and 144 trajectories remain ambiguous, which are likely mundane objects but cannot be further elucidated at this stage of development without information about distance and kinematics or other sensor modalities. We demonstrate the application of a likelihood-based statistical test to evaluate the significance of this toy outlier analysis. Our observed count of ambiguous outliers combined with systematic uncertainties yields an upper limit of 18,271 outliers for the five-month interval at a 95% confidence level. This test is applicable to all of our future outlier searches.
The UFO files : the inside story of real-life sightings
Offers real-life accounts of UFO sightings recorded in files collected by Britain's Ministry of Defence investigation unit and currently held at the National Archives.
Alien Life Imagined
One day, astrobiologists could make the most fantastic discovery of all time: the detection of complex extraterrestrial life. As space agencies continue to search for life in our Universe, fundamental questions are raised: are we awake to the revolutionary effects on human science, society and culture that alien contact will bring? And how is it possible to imagine the unknown? In this book, Mark Brake tells the compelling story of how the portrayal of extraterrestrial life has developed over the last two and a half thousand years. Taking examples from the history of science, philosophy, film and fiction, he showcases how scholars, scientists, film-makers and writers have devoted their energies to imagining life beyond this Earth. From Newton to Kubrick, and Lucian to H. G. Wells, this is a fascinating account for anyone interested in the extraterrestrial life debate, from general readers to amateur astronomers and undergraduate students studying astrobiology.
Alien Life Is No Joke
Alien life, once dismissed as a joke, is now being taken seriously by the scientific community. The search for extraterrestrial life has gained momentum, with NASA investing in astrobiology and the development of the Habitable Worlds Explorer telescope. However, alongside this scientific pursuit, there is a growing interest in UFO and UAP sightings, which have historically been associated with fringe culture. These two movements, the scientific search for life and the fascination with UFOs, are intertwined but not necessarily in a positive way. The association with UFOs has hindered the credibility of the search for extraterrestrial intelligence in the past. As a researcher in technosignatures, the study of advanced alien technology, Frank faces the challenge of overcoming the giggle factor and establishing proper standards of evidence. Understanding the history of UFOs and the scientific search for life is crucial in navigating this complex field. As a scientist, he strives to comprehend how non-scientists approach the topic of UFOs and aliens, in order to communicate effectively and maintain high standards of evidence in astrobiology.
