Footage of Nuclear-Weapons Tests Declassified

After decades spent slowly disintegrating in high-security vaults, thousands of historic films of U.S. nuclear weapons tests have been salvaged, including some that have been newly declassified. The incredible footage shows enormous mushroom clouds ballooning over the horizon in what could be a doomsday flick.

A mushroom cloud forms after a nuclear weapons test dubbed Operation Hardtack-1 – Nutmeg in May 1958 on Bikini Atoll in the Pacific Ocean.

The week’s hottest temperature was 111.0 degrees Fahrenheit (44.0 degrees Celsius) in Port Hedland, Western Australia.

The week’s coldest temperature was minus 89.0 degrees Fahrenheit (minus 67.2 degrees Celsius) at Vostok, Antarctica.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

Drought in Somalia

At least 110 people, most of them women and children, have died from starvation and drought-related illness in Somalia in the past 48 hours, Prime Minister Hassan Ali Khaire said Saturday.

The death toll covers those who died in the rural areas of Somalia’s southwestern Bay region where the drought is more severe than other parts of the country. It was not immediately clear how many others have died in the rest of the country.

Researchers working in the South Pacific have captured stunning footage of a deep-sea jellyfish that looks like a flying saucer with tentacles. Marine biologists working on the National Oceanic and Atmospheric Administration’s Okeanos Explorer spotted this beautiful jelly at Utu Seamount in the National Marine Sanctuary of American Samoa.

‘Ring of Fire’ Eclipse Will Be Visible from Southern Hemisphere Sunday

This Sunday (Feb. 26) brings the first solar eclipse of 2017. Unlike the total solar eclipse that will cross the continental United States in August, Sunday’s spectacle is an annular eclipse, which means a sliver of the sun’s surface will still be visible around the moon.

The moon will appear to block varying amounts of the sun depending on where you are located within the eclipse visibility zone. For those who are properly positioned along a narrow path some 8,500 miles (13,700 kilometres) long and averaging roughly 45 miles (72 km) wide, the dark disk of the moon will briefly be surrounded by a dazzling “ring of fire” as the lunar disk passes squarely in front of the sun.

Skywatchers positioned outside this path can still enjoy a partial solar eclipse. This spectacle will be visible to more than half a billion people living across the lower two-thirds of South America as well as the western and southern portions of Africa, as well as the sparse population in about half of Antarctica.

Astronomers Find 7 Earth-Size Planets Where Life Is Possible

Astronomers have found a nearby solar system with seven Earth-sized planets, three of which circle their parent star at the right distance for liquid surface water, bolstering the prospect of discovering extra-terrestrial life, research published on Wednesday showed.

The star, known as TRAPPIST-1, is a small, dim celestial body in the constellation Aquarius. It is located about 40 light years away from Earth, close by astronomical standards, but about 44 million years away at the average cruising speed of a commercial passenger jet.

Researchers said the proximity of the system, combined with the proportionally large size of its planets compared to the small star, make it a good target for follow-up studies. They hope to scan the planets’ atmospheres for possible chemical fingerprints of life.

“The discovery gives us a hint that finding a second Earth is not just a matter of if, but when,” Nasa chief scientist Thomas Zurbuchen said at a news conference on Wednesday.

This is the first time that so many Earth-sized planets are found around the same star,” lead researcher Michael Gillon, with the University of Liege in Belgium, told reporters.

Residents in Singapore were treated to a truly unusual phenomenon, as a so-called fire rainbow lit up the sky in the city-state. NASA says that fire rainbows are actually called circumhorizon arcs, which are created by a unique set of circumstances. A spokesman said: “The sun must be at least 58 degrees high in a sky where cirrus clouds are present. Furthermore, the numerous, flat, hexagonal ice-crystals that compose the cirrus cloud must be aligned horizontally to properly refract sunlight like a single gigantic prism. Therefore, circumhorizon arcs are quite unusual to see.”
