Many U.S. presidents during their terms were seriously interested in UFOs and extraterrestrial intelligence issues, and some of them even had a chance to make contact with aliens. We turn to the recently declassified archives of ufology. Let’s start with 1948, when President Harry S. Truman summoned his Assistant Robert Landry to the Oval Office.

Truman gave him the order to make reports every three months on the flying saucers observed over the country. Once, Truman asked to investigate the case of the appearance of mysterious object over Washington that he observed through his window. (more…)

NASA’s Galileo Reveals Magma ‘Ocean’ Beneath Surface of Jupiter’s Moon

A new analysis of data from NASA’s Galileo spacecraft has revealed that beneath the surface of Jupiter’s volcanic moon Io is an “ocean” of molten or partially molten magma.

The finding, from a study published May 13 in the journal Science, is the first direct confirmation of such a magma layer on Io and explains why the moon is the most volcanic object known in the solar system. The research was conducted by scientists from UCLA, UC Santa Cruz and the University of Michigan–Ann Arbor. (more…)

NASA Shows Topography of Tsunami-Damaged Japan City

The topography surrounding Sendai, Japan is clearly visible in this combined radar image and topographic view generated with data from NASA’s Shuttle Radar Topography Mission (SRTM) acquired in 2000. On March 11, 2011, a magnitude 8.9 earthquake struck offshore about 130 kilometers (80 miles) east of Sendai, the capital city of Japan’s Miyagi Prefecture, generating a tsunami that devastated the low-lying coastal city of about 1 million residents.

The city is centered in the image and lies along the coastal plain between the Ohu Mountains and the Pacific Ocean. The eastern part of the city is a low-lying plains area, while the city center is hilly (the city’s official elevation is about 43 meters, or 141 feet). Sendai’s western areas are mountainous, with its highest point being Mt. Funagata at an elevation of about 1,500 meters (4,921 feet) above sea level. (more…)

The epic ocean-spanning journeys of the gigantic leatherback turtle in the South Atlantic have been revealed for the first time thanks to groundbreaking research using satellite tracking.

Experts at the Centre for Ecology and Conservation (Cornwall) at the University of Exeter led a five-year study to find out more about these increasingly rare creatures and inform conservation efforts. (more…)

‘Undersea Methane Could be Contributor to Increased Ocean Acidity’

A North Carolina State University researcher is part of a team which has found that methane from “cold seeps” – undersea areas where fluids bubble up through sediments at the bottom of the ocean – could be contributing to the oceans’ increasing acidity and stressing already delicate undersea ecosystems.

Oceanic microorganisms and bacteria survive by consuming dissolved organic carbon, or DOC. A byproduct of this consumption is CO2 – carbon dioxide – which, in large enough concentrations, makes seawater more acidic. (more…)

Mysteries of Unpredictable Tsunami Waves

One of the most terrible consequences of offshore quakes is giant tsunami waves, sweeping everything on their way. Until now, scientists cannot answer a simple question: why in some cases they happen, and in others they do not? If it was established, then a tragedy like the one that has recently occurred in Indonesia could have been avoided.

An earthquake measuring 7.5 points, which occurred late on Monday, October 25 in Indonesia, caused a tsunami, which affected Mentawai islands in the western part of the country. Interestingly, the epicenter of the aftershocks of this earthquake was located 78 km west of the South Island Pagai of the Mentawai archipelago, at a depth of 20 km below the bottom of the Pacific Ocean. Apparently, this is why the first few minutes after the earthquake the Indonesian government reported the tsunami threat, but later canceled the alert. (more…)
