GRAIL Generates High Resolution Gravity Field Map of the Moon

porosity of the lunar surface

New data from NASA’s Ebb and Flow probes was used to generate a high resolution gravity field map of the moon, showing that the moon’s gravity field is unlike that of any terrestrial planet in our solar system and revealing an abundance of features never before seen in detail. Pasadena, California — Twin NASA probes […]

Astronomers Identify a New Kind of Galaxy, “Green Bean Galaxies”

J2240

Located in the constellation of Aquarius, roughly 3.7 billion years from Earth, galaxy J2240 has been identified as part of a new class of galaxies nicknamed “green bean galaxies.” A new galaxy class has been identified using observations from ESO’s Very Large Telescope (VLT), the Gemini South telescope, and the Canada-France-Hawaii Telescope (CFHT). Nicknamed “green […]

Eurasian Jays Aware When Others Are Listening

eavesdropping-eurasian-jay

A new study indicates that Eurasian jays (Garrulus glandarius) are aware that others may be watching them while they hide away nuts and seeds for the winter, but they might also be aware when others are surreptitiously listening. The scientists published their findings in the journal Proceedings of the Royal Society B. In response, the birds […]

Nyasasaurus, Oldest Dinosaur Believed to Be 243 Million Years Old

Nyasasaurus

Paleontologists think that they may have identified the earliest known dinosaur, which was no bigger than a Labrador retriever and lived 243 million years ago, during the Triassic Period. This is 10 million years earlier than the previously oldest known dinosaurs, and could change researchers’ views of how they evolved. The scientists published their findings […]

Underground nuclear tests can be detected in the skies and as a result, global satellite networks could become a powerful tool in order to detect clandestine underground nuclear explosions (UNE). The scientists presented their findings at the American Geophysical Union conference. The International Monitoring System (IMS) was established by the Comprehensive Nuclear-Test-Ban Treaty and has […]

Yale Engineers Develop Micro Fuel Cells Made of Bulk Metallic Glasses

micro fuel cell made of glass

Made up of mostly bulk metallic glasses, a new type of micro fuel cell could serve as a low-cost, long-lasting, and eco-friendly power source for portable electronic devices. Engineers at Yale University have developed a new breed of micro fuel cell that could serve as a long-lasting, low-cost, and eco-friendly power source for portable electronic […]

One of the strangest moons in the Solar System is Saturn’s Iapetus, which features an enormous equatorial mountain ridge and spiky belt that rises 12 miles above the moon’s surface may have all been the result of a single impact. The findings were presented at the American Geophysical Union conference on December 4. Scientists suggest […]

Cocoons form to protect eggs and larvae, but they can also help preserve fossils for hundreds of millions of years. This 25-micrometer-long protozoan was trapped in the wall of an egg case produced by a leech between 200 million and 215 million years ago, during the Triassic Period. The scientists published their findings in the […]

Herschel and Keck Reveal Previously Unseen Starburst Galaxies

previously unseen starburst galaxies revealed

Using ESA’s infrared Herschel space observatory and spectrometers on the twin 10-metre W.M. Keck telescopes on Mauna Kea, Hawaii, astronomers characterized 767 previously unseen starburst galaxies, revealing extraordinary high star-formation rates across the history of the Universe. Starburst galaxies give birth to hundreds of solar masses’ worth of stars each year in short-lived but intense […]

A 5-mile wide and 3,000 foot deep asteroid impact crater has been hidden near Bow City, Alberta, for millions of years. Bow City has been deserted for decades. The findings were presented at the American Geophysical Union conference on December 3rd. People have suspected something odd in the region since the 1930s, because of the […]

Humans are a Greater Disturbance to Elk than Natural Predators

vigilant-elk

A new study has shown that elk become more fearful when people are around because they perceive humans as predators. The scientists published their findings in the journal PLOS ONE. The researchers studied elk (Cervus canadensis) in Alberta, Canada. The results come from a year-long study that tracked 424 herds and 870 individuals on public, […]

Titan’s Icy Outer Crust is Likely Twice as Thick as Previously Believed

Titan's icy outer crust is likely twice as thick as previously thought

Using radar data from NASA’s Cassini spacecraft, a new analysis of Saturn’s largest moon, Titan, suggests that it has an icy, rocky core with a radius of a little over 2,000 kilometers, an ocean somewhere in the range of 225 to 300 kilometers thick and an ice layer that is 200 kilometers thick. A new […]
