Ancient rhinos in Nebraska lived in large local herds and died slowly from volcanic ashfall, not sudden disaster. Credit: John Haxby/The University of Nebraska State Museum ************************************************************************* Volcanic eruption from 12 million years ago preserves a snapshot of extinct animal life. Rhinos that once roamed much of North America 12 million years ago likely lived in large herds, according to a new study by the University of Cincinnati. Researchers examined isotopes in the teeth of rhinos found in what is now northeast Nebraska. At this site, more than 100 rhinos died at a single water hole and were buried in...

Archaeologists have uncovered the ruins of an ancient Egyptian town dating back 3,400 years near the city of Alexandria, according to a recent study published in Antiquity. The researchers from the French National Centre for Scientific Research have theorized that the mud-brick settlement was likely founded during Egypt‘s 18th Dynasty (ca. 1550 BCE–1292 BCE), due to the presence of items bearing an amphora stamp with the name Merytaton. Merytaton was the daughter of the pharaoh Akhenaten and his wife Nefertiti and the sibling of Tutankhamun, better known as King Tut.

A dramatic twist in cosmic storytelling: A Jupiter-sized planet didn’t get swallowed by an expanding red giant, as astronomers once believed. Instead, NASA’s James Webb Space Telescope uncovered that the planet spiraled inward over time, ultimately plunging into its star in a fiery cosmic demise. Credit: NASA, ESA, CSA, Ralf Crawford (STScI) ********************************************************************** Lingering Brightness Provides Evidence for How the Planet Met Its Demise Each year, scientists from around the world compete for a chance to use NASA’s James Webb Space Telescope. Proposals go through a rigorous review process, and approved projects are added to Webb’s observation schedule, which is...

Astronomers have just revealed that a day on Uranus is longer than was previously thought, at 17 hours, 14 minutes and 52 seconds. This is 28 seconds longer than the previous estimate, which was made by NASA's Voyager 2 probe during its flyby of the ice giant planet back in 1986. The new figure—which is 1,000 times more accurate—was calculated based on a decade's worth of observations of Uranus's aurorae made by NASA/ESA's Hubble Space Telescope. The long-term data on the planet's auroral emissions enabled the researchers to track the positions of the planet's magnetic poles and, by extension, its...

In a rare announcement that has captured the attention of scientists and the public alike, NASA has issued a warning about an asteroid with a 4% chance of striking the Moon in 2032. The news, which has stirred both intrigue and concern, highlights the ongoing efforts to monitor near-Earth objects (NEOs) and assess potential threats to our planet and its natural satellite. Astronomers tentatively designated the asteroid 2025-XF47. NASA’s Near-Earth Object Observations Program first detected it earlier this year. According to a statement from the agency, widely reported by outlets like CNN and BBC News, the object measures approximately 150...

Some of the objects captured by ASKAP. (Author provided) ******************************************************************************* Radio astronomers see what the naked eye can’t. As we study the sky with telescopes that record radio signals rather than light, we end up seeing a lot of circles. The newest generation of radio telescopes – including the Australian Square Kilometre Array Pathfinder (ASKAP) and MeerKAT, a telescope in South Africa – is revealing incredibly faint cosmic objects, never before seen. In astronomy, surface brightness is a measure that tells us how easily visible an object is. The extraordinary sensitivity of MeerKAT and ASKAP is now revealing a new...

Ground-based telescopes from the International Asteroid Warning Network have been tracking the asteroid, but it will be too faint to observe until June 2028...That’s why Webb was called in for the job, measuring the asteroid’s brightness across a range of infrared wavelengths to better determine its size. In late January, a team of scientists proposed using the mid-infrared instrument on Webb to observe the asteroid and better understand its damage potential. The team recently released the preliminary results of Webb’s observations of asteroid 2024 YR4, suggesting that, while the asteroid is larger and rockier than previous observations, it has nearly...

If you look at a map of Earth's gravity, you will see a huge blue spot south of India, indicating a region where gravity is weaker than average. This spot is called the Indian Ocean Geoid Low (IOGL), and it is the largest gravity anomaly on our planet.A gravity anomaly is a difference between the actual gravity measured at a location and the theoretical gravity expected for a perfectly smooth and spherical Earth. But Earth's gravity isn't perfectly uniform and variations in mass distribution beneath the surface cause fluctuations in gravitational pull.Gravity anomalies can be caused by variations in the...

Egypt's Supreme Council of Antiquities (SCA) announced the discovery of a tomb belonging to a high-ranking military commander who served during the reign of Ramesses III (reigned ca. 1184–1153 b.c.), Ahram Online reports. The burial was uncovered during excavations at the site of Tell Roud Iskander in Ismailia. The mudbrick structure contained a burial chamber and three adjoining rooms with walls covered in white plaster. Among the artifacts found within the tomb were bronze arrowheads, painted alabaster jars, a collection of beads, a small ivory box, and a gold ring engraved with a cartouche of Ramesses III. The soldier was...

All four of the sun’s giant planets emit more energy than they receive from the sun. Like the sun’s other giant worlds, Uranus (seen in this 1986 photo from the Voyager 2 spacecraft) radiates more energy than the sun gives it, though not nearly as strongly as its massive peers do. JPL/NASA ===================================================================== Uranus emits more energy than it gets from the sun, two new studies report — a discovery that contradicts findings from the venerable Voyager spacecraft. When Voyager 2 sped past Uranus on January 24, 1986, the spacecraft detected no significant excess heat from the planet, making it...

Samples drilled from deep beneath the sea have revealed just how much global sea levels changed following the last ice age. Melting ice caps in North America, Antarctica and Europe caused sea levels to rise quickly as temperatures warmed after the last ice age. But researchers have lacked robust geological data from this period, so how much sea levels climbed was unknown. Now, new geological data show that sea levels rose about 125 feet (38 meters) between 11,000 and 3,000 years ago, according to a study published March 19 in the journal Nature. The findings could help scientists and policymakers...

Who was the king of Assyria during the ministry of Jonah? This isn’t a question I’ve really heard discussed before. Now, having looked into it, it seems we have a strong candidate. And that in part because of an ancient solar eclipse. The biblical text of Jonah never names the king who presided over Nineveh during its great repentance, simply calling him “the king of Nineveh” (Jonah 3:6). But the Bible does tell us which king was on the throne of Israel during Jonah’s ministry – Jeroboam II. This king of Samaria ruled from 782 – 753 B.C., during a...

Montet's discovery on the eve of the Second World War was that of a tomb of a relatively obscure pharaoh of the 21st Dynasty of ancient Egypt by the name of Psusennes I. Psusennes was the third ruler of his dynasty, which ascended to power at the onset of the Third Intermediate Period, a time of political turmoil in Egypt.During this era, the country's kingship was fragmented, and the country was divided between Upper and Lower Egypt. While the pharaohs of the 21st Dynasty governed from Tanis, their influence was primarily confined to the Lower Egypt delta region. Meanwhile, Thebes...

The race between Jupiter and Saturn for the most moons in the Solar System may have just finally come screeching to a halt. A team of scientists has found a whopping 128 previously unknown moons hanging around Saturn, in a discovery officially recognized by the International Astronomical Union. This brings the planet's total number of known moons to 274, leaving Jupiter, with its mere 95 moons, in the dust. The first hint that there were more moons awaiting discovery came between 2019 and 2021, when 62 such objects were identified. Other small objects were also spotted at the time that...
