    In the early 20th century, sailors near Alaska reported seeing black bubbles seeming to boil out from the sea, each one the size of the dome of the capitol building in Washington, D.C. They weren't the only sailors who reported the bizarre phenomenon, and they weren't mistaken, except for one thing … the bubbles were much larger. When the mostly underwater Bogoslof volcano in the Aleutian Islands erupts, it produces giant bubbles that can reach up to 1,444 feet (440 meters) across, according to a new study. These bubbles are filled with volcanic gas, so when they burst they create...

    ...The 2,700-metre-long avenue of sphinxes was built during the reign of Pharaoh Nectanebo I of the [30]th-Dynasty. It replaced one built formerly in the 18th Dynasty, as Queen Hatshepsut (1502-1482 BC) recorded on the walls of her red chapel in Karnak Temple. According to this, she built six chapels dedicated to the god Amun-Re on the route of the avenue during her reign... The excavation team unearthed a large number of fragmented sphinxes that are now undergoing restoration in an effort led by SCA consultant Mahmoud Mabrouk. Once restored, they will be placed on display along the avenue... Archaeologists have...

    Along with locations in North and South America, Greenland, Western Europe, and the Middle East, we can now add southern Africa to the list of places where scientists have uncovered evidence of a calamitous event that happened 12,800 years ago. This evidence of a 12,800-year-old platinum spike in Africa is the first to be found on the continent, and it’s yet further evidence in support of the Younger Dryas Impact Hypothesis. According to this theory, either a comet or asteroid struck Earth during the Pleistocene, triggering an impact winter that saw temperatures plummet around the globe. The associated loss of...

    Scientists aren't particularly surprised to find volcanism in the region, which is home to active volcanoes like Mount Vesuvius and Mount Etna. But the new complex is unusual because it was created by a rare kind of fault... The western Mediterranean is seismically restless because of the collision of three tectonic plates: the African, the Eurasian and the Anatolian. Making matters more complex is a small chunk of crust called the Adriatic-Ionian microplate, which broke off of the African Plate more than 65 million years ago and is now being pushed under the larger Eurasian Plate in a process called...

    Billions of years ago, something slammed into the dark side of the moon and carved out a very, very large hole. Stretching 1,550 miles (2,500 kilometers) wide and 8 miles (13 km) deep, the South Pole-Aitken basin... For decades, researchers have suspected that the gargantuan basin was created by a head-on collision with a very large, very fast meteor. Such an impact would have ripped the moon's crust apart and scattered chunks of lunar mantle across the crater's surface, providing a rare glimpse at what the moon is really made of. ... Now, however... After analyzing the minerals in six...

    he biblical kingdom of Edom has always been a significant puzzle for biblical archaeology. Although evidence is supplied in the Bible, the archaeological record has always had trouble interpreting the text, which said that it existed as a kingdom long before the kings of Israel. But research has uncovered the untold story of a thriving and wealthy society in the Arava Desert – in parts of Israel and Jordan – that existed during the 12th-11th centuries BCE.  Collecting slag and charcoal samples from “Slaves’ Hill”, Timna Valley, Israel.

    At midnight on Mars, the red planet’s magnetic field sometimes starts to pulsate in ways that have never before been observed. The cause is currently unknown. That’s just one of the stunning preliminary findings from NASA’s very first robotic geophysicist there, the InSight lander. Since touching down in November 2018, this spacecraft has been gathering intel to help scientists better understand our neighboring planet’s innards and evolution, such as taking the temperature of its upper crust, recording the sounds of alien quakes, and measuring the strength and direction of the planet’s magnetic field. As revealed during a handful of presentations...

    The asteroid, called "2019 OK," passed about 40,400 miles above Earth's surface — roughly 5 times closer to Earth than the moon — at 55,000 miles per hour and could have "created localized devastation to an area roughly 50 miles across" if it struck land, according to a NASA news release. "An asteroid of this size coming this close to Earth is a pretty rare event — on the order of about twice a century," according to Paul Chodas, manager of NASA’s Center for Near-Earth Object Studies at JPL.

    The team used the Osiris instrument at the 10.4m Gran Telescopio Canarias in La Palma, Spain, to obtain visible spectra - measurements of sunlight reflected by Borisov. By studying these spectra, scientists can draw conclusions about its chemical composition, including how it might differ from comets that were "born" around the Sun. "The spectrum is the red side of the comet's total spectrum, so the only thing we can see in the spectrum is the slope," said Miquel Serra Ricart, from the Instituto de Astrofísica de Canarias (IAC) in Tenerife. In coming days, the team will obtain measurements of the...

    The Minoans and their capital Knossos weren’t incinerated by volcanic blast from Thera or flattened by quake as thought, but tellingly: their writing system changed. The mystery of what happened to the Minoan civilization has tormented archaeologists for over a century, and the tale has now taken a new twist. Nothing happened to them, say archaeologists who have been excavating the island of Crete for over thirty years. This extraordinary people, who produced palatial architecture unparalleled in the Aegean region at the time, were not immolated by the volcanic eruption of Thera as once thought, crushed by earthquake, or squashed...

    A comet first spotted by a Ukrainian amateur astronomer looks to be just the second known object to visit our cosmic neighborhood from beyond the solar system. What could be an even bigger deal is that this one was discovered as it's still approaching us. The comet was found by Gennady Borisov of Crimea on Aug. 30, and went by the temporary name GB00234 until very recently. After being watched by several other observatories over the past few weeks, it was given the official name of C/2019 Q4 (Borisov) by the Minor Planet Center on Wednesday. It appeared to follow...

    AN ASTEROID which came crashing into Earth and NASA had no idea it was coming reiterates the need to keep a closer eye on the sky in case a massive space rock comes hurtling towards our planet. A small asteroid shot towards Earth at 14.9 kilometres per second, and NASA admitted it did not know it was coming. The space rock known as 2019 MO was just three metres wide and exploded when it hit the planet’s atmosphere on 22 July above the Caribbean, but the way it approached unexpectedly reaffirms the need for more eyes on the sky.

    Some people heard it as a boom, some as a bang, some as a series of explosions. Imagine the noise of a dump truck being dropped from 100 feet in the air onto pavement. It shook buildings. Many people said it sounded like it was coming from inside their building on their block. But it wasn’t just local; people heard it around the same time across a huge swath of northern New York. In response to an Enterprise Facebook post, people wrote that they had heard it as far west as Cranberry Lake, as far north as Malone, as far...

    Steamboat has erupted 34 times as of Tuesday, according to the US Geological Survey. That breaks last year's record of 32 eruptions -- the largest number ever recorded in a year. The record before that was 29 eruptions in 1964. June's outbursts smashed the record for the shortest interval between eruptions -- just over three days. Scientists aren't sure what's behind the recent increase in activity, but the short answer is that this is just how geysers work. It's a popular misconception that geyser eruptions are related to earthquake activity, but Poland said visitors to the national park have nothing...

    Earth was born as a result of repeated asteroid collisions, the moon was created by a single giant impact event. Then, Earth's size attracted huge meteorites, which slammed into it, causing super-high-temperature rock vapour to cover the entire surface and evaporate all ocean water. The earliest life-forms survived such infernal events by escaping deep into the ground, miraculously emerging again and again. The Earth has gone through innumerable catastrophic events, and life has survived by acquiring new abilities to live through each crisis. Humans are part of the grand history of life's evolution, which has been closely intertwined with repeated...

Now, the same asteroid has been caught switching colours, from red to blue in near-infrared spectrum by astronomers at the Massachusetts Institute of Technology (MIT), United States. This is the first time in the history of extraterrestrial materials that that astronomers have seen any shift in colours in an asteroid. Gault now glows in a blue tinge as a result of a less irradiated layer of the asteroid coming to light. According to the study’s...

    A metal asteroid worth $10,000 quadrillion, hurtling through space, makes construction of a massive orbital space station substantially cheaper. At least one company is already pitching a plan for a Von Braun Gateway Station housing some 1,500 people in orbit. The resources on the single asteroid, 16 Psyche, is not only enough to build the station, but to wipe out the U.S. national debt thousands of times over.
