    A star mystery solved? These newfound stars could help solve the so-called "photon underproduction crisis," which suggests that an extraordinary amount of ultraviolet light appears to be missing from the universe. The intergalactic stars could also help address what is known as the "missing baryon problem." Baryons are a class of subatomic particles that includes the protons and neutrons that make up the hearts of atoms inside normal matter. Theories of the formation and evolution of the universe predict there should be far more baryons than scientists currently see. The baryons that astronomers have accounted for in the local cosmic...

    Geologists from GUtech, in cooperation with archeologists from the Ministry of Heritage and Culture, have dug up evidence of a tsunami or severe storm that hit Ras Al Hadd about 4,500 years ago...The fact that there were two settlement phases, the first of which was marked by buildings made of sand brick, and the second by mud brick, suggests the village was destroyed at one point and rebuilt. The remains date back to between 3,100 and 2,700 BC, and the evidence suggests they were built one after the other, meaning the people didn't leave the area despite having their homes...

    Abigail and Dr. James Van Allen and his wife, Abigail, met “by accident” when she backed into his car at a stoplight in Baltimore. He scowled, but said nothing. When she ran into him again a few minutes later at the applied physics lab at Johns Hopkins University where they worked, she said, “Who do you think you are, throwing those dirty looks?” He called her the following Sunday to go bicycling. The Van Allens married on Oct. 13, 1945, in Southampton, Long Island. They lived right outside Washington, D.C., until 1951 when Van Allen accepted the position of head...
  • Astronomy: Planets in chaos. Standard ideas of Planet formation are being demolished

    NATURE ^ | 07/02/2014 | Ann Finkbeiner
    The discovery of thousands of star systems wildly different from our own has demolished ideas about how planets form. Astronomers are searching for a whole new theory. Not so long ago — as recently as the mid-1990s, in fact — there was a theory so beautiful that astronomers thought it simply had to be true. They gave it a rather pedestrian name: the core-accretion theory. But its beauty lay in how it used just a few basic principles of physics and chemistry to account for every major feature of our Solar System. It explained why all the planets orbit the...

    It might seem strange to say it, but I am a global warming skeptic because of Carl Sagan. This might seem strange because Sagan was an early promoter of the theory that man-made emissions of carbon dioxide are going to fry the globe. But it’s not so strange when you consider the larger message that made Sagan famous.

    Explanation: If you could look across Venus with radar eyes, what might you see? This computer reconstruction of the surface of Venus was created from data from the Magellan spacecraft. Magellan orbited Venus and used radar to map our neighboring planet's surface between 1990 and 1994. Magellan found many interesting surface features, including the large circular domes, typically 25-kilometers across, that are depicted above. Volcanism is thought to have created the domes, although the precise mechanism remains unknown. Venus' surface is so hot and hostile that no surface probe has lasted more than a few minutes.

    High-altitude winds on neighboring Venus have long been known to be quite speedy, whipping sulfuric-acid-laden clouds around the superheated planet at speeds well over 300 km/h (180 mph). And after over six years collecting data from orbit, ESA’s Venus Express has found that the winds there are steadily getting faster… and scientists really don’t know why. By tracking the movements of distinct features in Venus’ cloud tops at an altitude of 70 km (43 miles) over a period of six years — which is 10 of Venus’ years — scientists have been able to monitor patterns in long-term global wind...

I now believe the flood, at the minimum, filled the land of Turkey up with water. As 1st Samuel 30:16 shows sometimes "the whole earth" or "all the earth" can refer to a country or land area.

    [Research] "findings support historians' belief that ancient myths ... may be based, at least in part, on real communities and people." Researchers from Coventry University analysed the texts of three ancient stories and compared the complex web of characters' relationships with the type of "social networks" that occur in real life. The results showed that the societies depicted in the stories strongly mirrored real social networks that had been mapped out by others. But modern fiction differed from the ancient myths, as well as from real social networks, in telltale ways.

    Scientists have discovered that Venus has an ozone layer. The thin layer, which is hundred of times less dense than the Earth's, was discovered by the European Space Agency's Venus Express craft, researchers report in the journal Icarus. Until now, ozone layers have only been detected in the atmospheres of Earth and Mars. The find could help astronomers refine their hunt for life on other planets. The European spacecraft spied the ozone layer when focusing on stars through Venus' atmosphere. The distant stars appeared fainter than expected, because the ozone layer absorbed some of their ultraviolet light.

    Comet Hartley 2 contains water more like that found on Earth than prior comets seem to have, researchers say. A study using the Herschel space telescope aimed to measure the quantity of deuterium, a rare type of hydrogen, present in the comet's water. The comet had just half the amount of deuterium seen in comets. The result, published in Nature, hints at the idea that much of the Earth's water could have initially came from cometary impacts. Just a few million years after its formation, the early Earth was rocky and dry; something must have brought the water that covers...

They hope future observations will reveal whether volcanic activity, turbulence in the planet's atmosphere, or charged particles from the sun are to blame. Amateur astronomer Frank Melillo of Holtsville, New York, first spotted the new feature, which is brighter than its surroundings at ultraviolet wavelengths, on the planet's southern hemisphere on 19 July. That same day, an amateur observer in Australia found a dark spot on Jupiter that had been caused by a meteoroid impact.

The lack of distinct information may be, in part, due to the fact that the Sea Peoples were active mostly away from the Aegean, and in lands where Greek colonization did not occur centuries later, and hence were cut off from the Aegean world.

    BOSTON—The number of Earth-like extrasolar planets suitable for harboring advanced life could be 10 times higher than has been assumed until now, according to a new modeling study. The finding contradicts the prevailing notion that a terrestrial planet needs a large moon to stabilize the orientation of its axis and, hence, its climate. In 1993, French mathematicians Jacques Laskar and Philippe Robutel showed that Earth’s large moon has a stabilizing effect on our planet’s climate. Without the moon, gravitational perturbations from other planets, notably nearby Venus and massive Jupiter, would greatly disturb Earth’s axial tilt, with vast consequences for the...

The study supports a 20-year-old theory that Mars remained small because it avoided collisions with planetary building material. The new finding is published in the journal Nature. In our early Solar System, well before planets had formed, a frisbee-shaped cloud of gas and dust encircled the Sun. Scientists believe that the planets grew from material pulled together by electrostatic charges - the...

    Astronomers have discovered a whole new class of alien planet: a vast population of Jupiter-mass worlds that float through space without any discernible host star, a new study finds. While some of these exoplanets could potentially be orbiting a star from very far away, the majority of them most likely have no parent star at all, scientists say. And these strange worlds aren't mere statistical anomalies. They likely outnumber "normal" alien planets with obvious parent stars by at least 50 percent, and they're nearly twice as common in our galaxy as main-sequence stars, according to the new study. Astronomers have...

    An international team of astronomers claim to have found free-floating "planets" which do not seem to orbit a star.Writing in Nature, they say they have found 10 Jupiter-sized objects which they could not connect to any solar system. They also believe such objects could be as common as stars are throughout the Milky Way. The objects revealed themselves by bending the light of more distant stars, an effect called "gravitational microlensing".Objects of large enough mass can bend light, as Albert Einstein predicted. If a large object passes in front of a more distant background star, it may act as a...

    Scattered about the Milky Way are floating, Jupiter-mass objects, which are likely to be planets wandering around the Galaxy's core instead of orbiting host stars. But these planets aren't rare occurrences in the interstellar sea: the drifters might be nearly twice as numerous as the most common stars. "This is an amazing result, and if it's right, the implications for planet formation are profound," says astronomer Debra Fischer at Yale University in New Haven, Connecticut. To find the wanderers, scientists turned their telescopes towards the Galactic Bulge surrounding the centre of the Milky Way. Using a technique called gravitational microlensing,...
  • Comet-like tail discovered trailing planet Mercury

    This is an image of Mercury's tail obtained from combining a full day of data from a camera aboard the STEREO-A spacecraft. The reflected sunlight off the planet's surface results in a type of over-exposure that causes Mercury to appear much larger than its actual size. The tail-like structure extending anti-sunward from the planet is visible over several days and spans an angular size exceeding that of a full Moon in the night sky.

    First, the bad news: the inner solar system is unstable. Given enough time, Jupiter's gravity could yank Mercury out of its present orbit. Two new computer simulations of long-term planetary motion — one by Jacques Laskar (Paris Observatory), the other by Konstantin Batygin and Gregory Laughlin (University of California, Santa Cruz) — have both reached the same disturbing conclusion. Says Laughlin, "The solar system isn't as stable as we'd thought." Both teams have found that Jupiter's gravity can increase Mercury's orbital eccentricity over time. Mercury's path around the Sun is already nearly as elliptical as Pluto's. But Jupiter can make...

    Hardly had the minimalist argument been developed than it was profoundly undermined by an archaeological discovery. In 1993 and 1994, several fragments of an Aramaic stela were found at the long-running excavation of Tel Dan led by Avraham Biran of Hebrew Union College in Jerusalem. The historical references in the inscription and the paleography of the writing make it clear that it dates to the ninth century B.C.E. Moreover, the text specifically mentions a king of Israel and a king of the "House of David" (Hebrew, bytdwd ), that is, a king of the dynasty of David. This discovery led...

    Human Remains in Ancient Jar a Mystery Jennifer Viegas, Discovery News Jan. 23, 2007 — For over 100 years, four blue-glazed jars bearing the nametag of Rameses II (1302-1213 B.C.) were believed to contain the Egyptian pharaoh's bodily organs. But analysis of organic residues scraped from the jars has determined one actually contained an aromatic salve, while a second jar held the organs of an entirely different person who lived around 760 years later. Now the question is, who was this individual? "We do believe that the unknown person was of importance for at least two reasons," said Jacques Connan,...
  • Moon has liquid core just like Earth...reveal sensors left on surface by astronauts 40 YEARS ago

    It's an unlikely marriage between state-of-the-art and 40-year-old technology that has yielded extraordinary results. Signals from seismic sensors left on the lunar surface by Apollo astronauts in 1971 have revealed that the Moon has a liquid core similar to Earth's. Scientists at Nasa applied contemporary seismological techniques to the data being emitted from sensors placed by their colleagues during the U.S. space program's heyday....

    A mysterious high-altitude layer of sulphur dioxide discovered by ESA’s Venus Express has been explained. As well as telling us more about Venus, it could be a warning against injecting our atmosphere with sulphur droplets to mitigate climate change. Venus is blanketed in sulphuric acid clouds that block our view of the surface. The clouds form at altitudes of 50–70 km when sulphur dioxide from volcanoes combines with water vapour to make sulphuric acid droplets. Any remaining sulphur dioxide should be destroyed rapidly by the intense solar radiation above 70 km. So the detection of a sulphur dioxide layer at...

    Astronomers have confirmed the first discovery of an alien planet in our Milky Way that came from another galaxy, they announced today (Nov. 18). The Jupiter-like planet orbits a star that was born in another galaxy and later captured by our own Milky Way sometime between 6 billion and 9 billion years ago, researchers said. A side effect of the galactic cannibalism brought a faraway planet within astronomers' reach for the first time ever. [Illustration of the extragalactic planet] "This is very exciting," said study co-author Rainer Klement of the Max-Planck-Institut fur Astronomie (MPIA) in Heidelberg, Germany. "We have no...
