New images reveal Ryugu is an oddly dust-free asteroid

A lander on the surface of Ryugu, a near-Earth asteroid, has shared new photos of the dark and rocky surface while highlighting new findings. The Japan Aerospace Exploration Agency’s Hayabusa2 spacecraft dropped a lander called Mobile Asteroid Surface Scout, or MASCOT, on the asteroid’s surface in October 2018. Ryugu is a dark, spinning top-shaped asteroid…MORE

The Amazon rainforest is on fire. Here’s what that means for the environment

The Amazon rainforest is an ecological marvel. It’s twice the size of India, according to the World Wildlife Fund, and it’s the largest remaining tropical rainforest in the world. It’s home to at least 10% of the world’s biodiversity, produces 20% of the world’s oxygen and helps regulate the temperature of the whole planet. Without…MORE

Atacama Desert offers clues about life on Mars

Atacama Desert offers clues about life on Mars

In order to search for life on other planets, scientists are studying extreme environments on Earth to understand what that life might look like if they find it. Future Mars rovers like NASA’s 2020 rover and the European Space Agency’s ExoMars missions will search the red planet in the coming years for signs of past…MORE

Scientists share new details about mysterious ‘ghost particle’

Scientists share new details about mysterious ‘ghost particle’

Neutrinos, so-called “ghost particles” scattered across the universe, can be 10 million times lighter than the mass of an electron, according to a new study. Neutrinos are referred to as ghostly because they are extremely volatile, or vaporous, cosmic particles that can pass through any kind of matter without changing. They have almost no mass…MORE

Life may have existed on warm, rainy, ancient Mars before winter came

Although Mars seems cold and inhospitable today, it was a different story 3 billion to 4 billion years ago. A new study suggests that the Red Planet was once warm enough to host pouring rainstorms and flowing water, which would have created an environment that could support simple life. The knowledge of water on ancient…MORE

Europe is sending an alien-hunting camera to Mars

Are we truly alone in this universe? The Red Planet may only be a drop in our immense cosmos, but Mars has always been a key place of curiosity when it has come to alien life. Now a high-tech camera could solve the age-old question: is there — or has there ever been — life…MORE

Black hole gobbles up neutron star, causing ripples in space and time

Black hole gobbles up neutron star, causing ripples in space and time

In the same decade when gravitational waves and a neutron star merger have been observed, astronomers have now observed what they believe to be the first detection of a black hole swallowing a neutron star. Last Wednesday, gravitational wave detectors in Italy and the US, called LIGO and Virgo, detected telltale ripples in space and…MORE

Hurricanes lead to more aggressive spiders, study says

Hurricanes lead to more aggressive spiders, study says

In regions of the United States and Mexico that are prone to hurricanes, aggressive spiders are evolving to survive and ride out the storm. When hurricanes rage along the Gulf of Mexico or charge up the East Coast, they can reshape an entire habitat in a short time. The winds destroy trees and spread debris…MORE
