Condition For The Deflection of Vertical Cracks at Dissimilar Ice Interfaces On Europa

The surface of Europa contains many quasi-circular morphologies called lenticulae. Although the formation mechanism of lenticulae is not understood, sill intrusion from the subsurface ocean is one promising hypothesis. However, it remains unclear how vertical cracks from the ocean deflect horizontally to allow sill intrusion in Europa. In this study, the critical stress intensity factor…

The Path that MASCOT Took Across Asteroid Ryugu During its 17 Hours of Life

The tiny hopping-robot MASCOT completed its 17 hour mission on the asteroid Ryugu in early October. Now the German Aerospace Center (DLR) has released an image of MASCOT’s path across the asteroid. Surprised by what MASCOT found on the surface, they’ve named the landing spot “Alice’s Wonderland.” MASCOT (Mobile Asteroid Surface Scout) was dropped onto…

Why tropical forests are so ecologically diverse

Working with high-resolution satellite imaging technology, researchers from Brown University and the University of California, Los Angeles have uncovered new clues in an age-old question about why tropical forests are so ecologically diverse. In studying Handroanthus guayacan,a common tropical tree species, over a 10-year period, they found that the tree population increased mainly in locations…

Rotational ‘Goldilocks’ Zones for Fractional Habitability and Silicate Weathering

Planetary rotation rate has a significant effect on atmospheric circulation, where the strength of the Coriolis effect in part determines the efficiency of latitudinal heat transport, altering cloud distributions, surface temperatures, and precipitation patterns. In this study we use the ROCKE-3D dynamic-ocean general circulation model to study the effects of slow rotations and increased insolations…

Soyuz Launch Carrying Two Astronauts is Forced to Abort, Landing Safely Back on Earth

The Soyuz MS-10 spacecraft carrying crew to the ISS was aborted shortly after launch on Thursday, Oct. 11th when its booster failed. The spacecraft executed an emergency ballistic landing with a sharp angle of descent. Both crew members on board—American astronaut Nick Hague and Russian cosmonaut Alexey Ovchinin—exited the capsule safely and are in good…

Scientists achieve first ever acceleration of electrons in plasma waves

The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) — operators of the world’s largest particle physics lab — near Geneva, Switzerland, is said to be the largest particle accelerator in the world. The accelerator lies in a tunnel 27 kilometers in circumference, as deep as 175 meters beneath the French-Swiss…

Ganymede Shows Evidence of Past Strike-slip Faulting

A recently published study led by researchers at the University of Hawai’i at Manoa School of Ocean and Earth Science and Technology reveals Ganymede, an icy moon of Jupiter, appears to have undergone complex periods of geologic activity, specifically strike-slip tectonism, as is seen in Earth’s San Andreas fault. This is the first study to…

Next Generation Telescopes Could Use “Teleportation” to Take Better Images

Telescopes have come a long way in the past few centuries. From the comparatively modest devices built by astronomers like Galileo Galilei and Johannes Kepler, telescopes have evolved to become massive instruments that require an entire facility to house them and a full crew and network of computers to run them. And in the coming…

New mechanism for how animal cells stay intact

Almost eight years ago, Stanford University bioengineer Manu Prakash was looking for a way to watch every cell in an adult living, behaving animal in elaborate detail. He searched the catalog of life and happened upon the simple marine animal Trichoplax adhaerens — or Tplax, as Prakash has come to call it. This ultra-flat animal…

Galactic Panspermia

We present an analytic model to estimate the total number of rocky or icy objects that could be captured by planetary systems within the Milky Way galaxy and result in panspermia should they harbor life. We estimate the capture rate of objects ejected from planetary systems over the entire phase space as well as time.…
