In a Wild Twist, Physicists Have Revived an Alternative Theory of Gravity

Out in the dark depths of space, our models of the Universe get messy. A new study looking at the ultra-diffuse dwarf galaxy AGC 114905 has revived a controversial theory (or more accurately a hypothesis) of gravity, and given us more questions than answers about what’s making our galaxies tick. It all starts with dark … Read more

Is Traffic Calming the Key to Robust Coral Reefs?

A team of researchers led by the Universities of Exeter and Bristol showed that reducing noise from motorboats through calming traffic could help fish breed more successfully in coral reefs. The scientists monitored three reefs for an entire breeding season to track the reproduction of the spiny chromis. The research was conducted on reefs near … Read more

End of the line nears for NASA InSight Mars lander

This Dec. 6, 2018 image made available by NASA shows the InSight lander. The scene was assembled from 11 photos taken using its robotic arm. The spacecraft is losing power because of all the dust that’s accumulated on its solar panels. NASA said Tuesday, May 17, 2022, it will keep using the spacecraft’s seismometer to … Read more

Researchers explain how auroras are formed on Mars without a global magnetic field

In July of 2021, we reported how the Hope probe sent by the United Arab Emirates to study the Martian atmosphere had released images of the nightside aurora on March. “They’re not easy to catch, and so that’s why seeing them basically right away with (Emirates Mars Mission) was kind of exciting and unexpected,” Justin … Read more
