New research has revealed that a giant impact on Mars more than four billion years ago would explain the unusual amount of “iron loving” elements in the Red Planet.
A new scenario seeking to explain how Mars’ putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million years earlier and were not as deep as once thought.
“It’s remarkable that we’ve now seen for the first time a physical object from outside our Solar System,” says Dr. Alan Jackson, a postdoc at the Centre for Planetary Sciences at the University of Toronto Scarborough in Ontario, Canada.
Nasa’s plan to deflect deadly asteroids wouldn’t be up to the job of keeping us safe from the deadly asteroid that could one day hit us, a study has found.
Neither the HAMMER concept nor Russia’s testing puts us on the doorstep of a nuclear asteroid defense system just yet, but they’re both steps in that direction.
NASA’s next Mars rover won’t just explore the Red Planet; it will, the space agency hopes, make it so a little bit of Mars might make it to Earth.
An international team of astronomers has discovered that all galaxies rotate once every billion years, no matter how big they are.
The modelling technique is a way of experimentally evaluating asteroid destruction criteria such as the explosion energy needed to eliminate a dangerous object on a collision course with Earth.
Nutrient-rich ash from an enormous flare-up of volcanic eruptions toward the end of the dinosaurs’ reign kicked off a chain of events that led to the formation of shale gas and oil fields from Texas to Montana.
Until now, astronomers assumed that the organics on Mars mainly came from dust particles from space. Now, computer simulations indicate that one third of the material comes from asteroids and comets.
The voiceover includes Morgan Freeman, Brian Cox, Carl Sagan, and David Attenborough. Each second represents 22 million years, which really puts into perspective how old our universe is.
Scientists and engineers have drawn up plans for a spacecraft that could knock big, incoming space rocks off course via blunt-force impact or blow them to bits with a nuclear warhead.
Apparently it is impossible to plot where module will re-enter the atmosphere, but the chance is higher in parts of Europe, US, Australia and New Zealand.
Hawking’s answer to the question “What was there before there was anything?” relies on a theory known as the “no-boundary proposal.”
Futurist Michio Kaku sees humans doing ballet on Mars and projecting their brains into the cosmos. And aliens? Oh, they’re coming.
