The cryptoterrestrial hypothesis: A case for scientific openness to a concealed earthly explanation for Unidentified Anomalous Phenomena

Posted by in category: space

Recent years have seen increasing public attention and indeed concern regarding Unidentified Anomalous Phenomena (UAP). Hypotheses for such phenomena tend to fall into two classes: a conventional terrestrial explanation (e.g., human-made technology), or an extraterrestrial explanation (i.e., advanced civilizations from elsewhere in the cosmos). However, there is also a third minority class of hypothesis: an unconventional terrestrial explanation, outside the prevailing consensus view of the universe. This is the ultraterrestrial hypothesis, which includes as a subset the “cryptoterrestrial” hypothesis, namely the notion that UAP may reflect activities of intelligent beings concealed in stealth here on Earth (e.g., underground), and/or its near environs (e.g., the moon), and/or even “walking among us” (e.g., passing as humans). Although this idea is likely to be regarded sceptically by most scientists, such is the nature of some UAP that we argue this possibility should not be summarily dismissed, and instead deserves genuine consideration in a spirit of epistemic humility and openness.

China’s ‘artificial sun’ achieves breakthrough in nuclear fusion

Posted by in categories: nuclear energy, space

Chinese scientists have made a groundbreaking milestone in nuclear fusion. They have announced a major achievement in discovering an advanced magnetic field structure “for the first time in the world” using the Huanliu-3 (HL-3) tokamak, also known as China’s “artificial sun.”

The discovery is the result of the first round of international joint experiments conducted on the HL-3 tokamak, a project that opened to global collaboration at the end of 2023.

Voyager 1 Returning Science Data From All Four Instruments

Posted by in categories: engineering, health, particle physics, science, space

Most distant spacecraft, #Voyager1, is now returning data from all four science instruments for the first time following a technical issue last November.

NASA’s Voyager 1 spacecraft is conducting normal science operations for the first time following a technical issue that arose in November 2023.

The team partially resolved the issue in April when they prompted the spacecraft to begin returning engineering data, which includes information about the health and status of the spacecraft. On May 19, the mission team executed the second step of that repair process and beamed a command to the spacecraft to begin returning science data. Two of the four science instruments returned to their normal operating modes immediately. Two other instruments required some additional work, but now, all four are returning usable science data.

The Habitable Worlds Observatory could See Lunar and Solar ‘Exo-Eclipses’

Posted by in categories: physics, space

A future space observatory could use exo-eclipses to tease out exomoon populations.

If you’re like us, you’re still coming down from the celestial euphoria that was last month’s total solar eclipse. The spectacle of the moon blocking out the sun has also provided astronomers with unique scientific opportunities in the past, from the discovery of helium to proof for general relativity. Now, eclipses in remote exoplanetary systems could aid in the hunt for elusive exomoons.

A recent study out of the University of Michigan in partnership with Johns Hopkins APL and the Department of Physics and the Kavli Institute for Astrophysics and Space Research at the Massachusetts Institute of Technology entitled “Exomoons & Exorings with the Habitable Worlds Observatory I: On the Detection of Earth-Moon Analog Shadows & Eclipses,” posted to the arXiv preprint server, looks to use a future mission to hunt for eclipses, transits and occultations in distant systems.

NASA selects RTX’s Blue Canyon Technologies to provide CubeSat buses for PolSIR mission

Posted by in categories: climatology, space

LAFAYETTE, Colo. - The U.S. National Aeronautics and Space Administration (NASA) has selected RTX’s small satellite manufacturer and mission services provider Blue Canyon Technologies in Lafayette, Colo., to build two 12U CubeSat buses for NASA’s PolSIR mission.

The PolSIR mission will study ice clouds that form at high altitudes throughout tropical and sub-tropical regions. In addition to designing and manufacturing the bus platforms, Blue Canyon will also provide mission operations services.

The PolSIR instrument –Polarized Submillimeter Ice-cloud Radiometer– will observe the full diurnal cycle of high-altitude ice clouds to improve climate forecasts and provide climate models with important insights into how Earth’s atmosphere will change in the future.
