  • Mars-sized 'Light-bridge' on Surface of Sun Appears to Signal Break-up of Vast Sunspot

    Newsweek ^ | 8/10/20 | Aristos Georgiou
    Amateur astronomer and Florida resident Howard Eskildsen snapped an image of the "light bridge"—which has a length that's roughly equal to the diameter of Mars—in a recently formed sunspot dubbed AR2770, spaceweather.com reported. These phenomena are caused by strong magnetic field concentrations, which inhibit convection—the transfer of heat from one place to another within gases and liquids. This process heats the solar surface. Hot "bubbles" of plasma—charged particles that are one of the four fundamental states of matter—are transported from deeper, hotter layers to the surface, whereas cooler plasma is transported back to the interior... According to Felipe, light bridges...

    The dwarf planet Ceres – long believed to be a barren space rock – is an ocean world with reservoirs of sea water beneath its surface, the results of a major exploration mission showed on Monday. Ceres is the largest object in the asteroid belt between Mars and Jupiter and has its own gravity, enabling the Nasa Dawn spacecraft to capture high-resolution images of its surface. Now a team of scientists from the United States and Europe have analysed images relayed from the orbiter, captured about 35km (22 miles) from the asteroid. They focused on the 20-million-year-old Occator crater and...

    A massive sunspot on the Sun is turning towards our planet and this could result in strong solar flares. The sunspot AR2770 was detected earlier this week and is expected to grow in size in the upcoming days. A report by SpaceWeather.com - a space weather forecasting website - said that multiple minor flares have been emitted by the sunspot already as it faced towards the earth. These flares have caused "minor waves of ionization to ripple through Earth's upper atmosphere" but nothing major yet. A clear picture of the AR2770 has also surfaced that gives a better idea into...
  • Researchers Discover Unexpected Magma Systems Lurking Beneath 'Boring' Volcanoes

    Analysing microscopic crystals in the basalt and ejected material of two volcanoes in the Galápagos, the researchers discovered hidden systems of magma that are not so simple or predictable after all. Even though the Wolf and Fernandina volcanoes in the Galápagos have seemingly spewed the same basaltic lava for their entire existence, the new findings suggest they are sitting on a chemically diverse system of molten rocks, some of which have the potential to set into motion explosive activity. Just because these volcanoes appear boring on the surface doesn't mean the monotony will continue forever, the researchers say. While the...
  • Asteroid Passed 'Extremely Close' To Earth Without Smacking Any Satellites [Hello And Goodbye, Asteroid 2020 OY4]

    YouTube ^ | recently | AstroBytes
    An asteroid named 2020 OY4, made its closest approach to our planet on July 28, when it was discovered just 26,000 miles away from Earth. It flew by earth at the range that rivals the orbits of some high-flying satellites. This is extremely close in astronomical terms, and just 11 percent of the average distance between the Earth and the moon. In fact, the data from NASA that tracks near-Earth objects suggests that the close approach of this asteroid was the closest that any asteroid will come to our planet for the next year. However, if you measure by the...

    Nearly a millennium and a half ago, red light streaked across the night sky over Japan. Witnesses compared it to the tail of a pheasant -- it appeared as a fan of beautiful red feathers stretched across the sky. Since the event, scientists have studied the witness accounts written in the year 620 A.D. and speculated about what the cosmic phenomenon could have actually been. Now, researchers from The Graduate University for Advanced Studies may have found the answer... "It is the oldest Japanese astronomical record of a 'red sign,'" said Ryuho Kataoka, a researcher with the Department of Polar...

    By comparing data collected by all-sky cameras, magnetometers, and seismometers during three aurora events in 2019, University of Alaska Fairbanks seismologist Carl Tape and colleagues show that it's possible to match the striking display of lights with seismic signals, to observe the same phenomenon in different ways. Researchers have known for a while that seismometers are sensitive to magnetic fluctuations—and have worked hard to find ways to shield their instruments against magnetic influence or to remove these unwanted signals from their seismic data. But the aurora study offers an example of how seismometers could be paired with other instruments to...

    The researchers found a Philistine cemetery in Israel – home to 145 human remains dating back to between the 11th and the 8th centuries BC. The discovery, made in 2013 and finally revealed in 2016, may yield answers to an enduring mystery surrounding the origins of the Philistines. It came at the end of a 30-year excavation by the Leon Levy Expedition. The Philistines were an ancient people who lived from the 12th century BC until 604 BC. They are known for their biblical conflict with the Israelites.

    Between 1997 and 2016, researchers at an excavation near Ashkelon in Israel examined the remains of more than one hundred humans, remains that dated from the 12th to 6th centuries before Christ. The researchers hoped to find human DNA in order to answer an old question: Who were the Philistines? Where did they come from? As it turns out, the Philistines were exactly who the Bible says they were, and they came from where the Bible says they did. Amos 9 speaks of God bringing up the Philistines from Caphtor, just as he brought Israel out of Egypt. Deuteronomy 2...

    Unique flagstones of Rabat Tepe Raise QuestionsThe discovery of 3000-year-old flagstones in Rabat Tepe has surprised archaeologists. Tehran, 20 October 2005 (CHN) -- The first season of archaeological excavations in Rabat Tepe led to the discovery of 3000-year-old 180x180 cm flagstone, which have never been seen before in any Urartu historical sites. Similar flagstones have been found in Ancient Rome and Ancient Iran historical sites. Rabat Tepe is located near the town of Sardasht in West Azarbaijan province of Iran. It is believed that hill used to be the capital of Musasir government about 3000 years ago. Before setting on...

    Findings also suggest exoplanets lying within habitable zones may be susceptible to ice ages. ============================================================================= At least twice in Earth’s history, nearly the entire planet was encased in a sheet of snow and ice. These dramatic “Snowball Earth” events occurred in quick succession, somewhere around 700 million years ago, and evidence suggests that the consecutive global ice ages set the stage for the subsequent explosion of complex, multicellular life on Earth. Scientists have considered multiple scenarios for what may have tipped the planet into each ice age. While no single driving process has been identified, it’s assumed that whatever triggered...

    A mysterious origin and Arthur C. Clarke-level science-fiction speculation about the 17-mile-wide, deeply-grooved moon as an alien artifact captured in the ancient past by Mars gravitational field, may explain Russia’s almost mystical obsession with Phobos. First the Soviet Union, then more recently, Russia, made three attempts to reach the enigmatic object, but software errors and launch disasters have aborted each attempt. In 2016 the BBC reported that a mysterious monolith object was spotted several years ago by a NASA probe, and to this day nobody is quite sure what it is or how it got there. Japan is on deck,...
  • Likely active volcanoes found on Venus, defying theory of dormant planet

    The Guardian ^ | Monday, July 20, 2020 | Agence France-Presse
    Scientists have identified 37 volcanic structures on Venus that appear to have been recently active - and probably still are today - painting the picture of a geologically dynamic planet and not a dormant world as long thought. The research focused on ring-like structures called coronae, caused by an upwelling of hot rock from deep within the planet's interior, and provided compelling evidence of widespread recent tectonic and magma activity on Venus's surface, researchers have said. Many scientists had long thought that Venus, lacking the plate tectonics that gradually reshape Earth's surface, was essentially dormant geologically, having been so for...

    The first ever photo of two planets orbiting a Sun-like star 309-light years from the Earth has been captured by astronomers using a ground-based telescope. The European Southern Observatory’s Very Large Telescope in Chile was used to capture the image of the two giant exoplanets orbiting the very young star. Astronomers say this image is a snapshot of an environment similar to our Solar System - but at an earlier stage in its evolution.

    NASA has said that asteroid 2011 ES4 will shuttle past the Earth in September at a much closer distance than the moon. 2011 ES4, listed on the Center for Near-Earth Object Studies (CNEOS)'s 'Close Approaches' database, will fly past the Earth on September 1 at 10:49 A.M. EDT. The asteroid will fly 0.00048 astronomical units away or about 44,618 miles at a speed of 18,253 miles per hour. Measuring 22 meters to 49 meters in diameter, NASA considered the asteroid as 'Potentially Hazardous', although there is no threat associated from it due to its amall diameter. NASA says, "Potentially Hazardous...
