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

Newly discovered stegosaurus fossil is the oldest in the world

A few vertebrae and the upper arm bone of a previously unknown species of stegosaurus have been found in the Middle Atlas Mountains of Morocco. And despite the lack of a complete skeleton, scientists say that at 168 million years old it’s the oldest known stegosaurus yet found. In particular, the neck vertebrae and the…MORE

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

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

Second exoplanet found around a curious star

Second exoplanet found around a curious star

Astronomers have discovered a second exoplanet hiding out in an intriguing star system. The Beta Pictoris system is 63.4 light-years from Earth. The star is very bright, and it’s surrounded by a giant disk made of dust, gas and debris — the leftovers of its formation. The star is also twice the mass of our…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
