Earth not due for a geomagnetic flip in the near future.

Over the past couple of hundred years, the strength of the Earth’s geomagnetic field has been waning, leading scientists to wonder if our planet’s polarity is on the verge of flipping. A new study suggests this won’t happen in the near future and that the intensity of today’s field is uncharacteristically strong. Predicting a geomagnetic flip is important for two primary reasons, one biological, one technological. The Earth’s magnetic field deflects solar wind and cosmic rays, so with a weakened...

Hot Jupiter ‘Companions’ could shed light on planet formation.

The discovery of two exoplanet "companions" provides insight into the hot Jupiter solar system, discovered from data collected by the K2 mission. Out of the some 300 hot Jupiters that have been spotted over the past two decades, these new objects are the first close-in planets to be discovered. Discovery of two close-in planet companions sheds new light on planet formation. For the past 20 years, astronomers peered into the night sky, puzzled about a type of planet called hot Jupiters. As they a...

Journey to Mars: Detour to the Moon is the best way to travel to the Red Planet.

As NASA gears up for a mission to Mars, planning a route to the Red Planet is important. Now, researchers have found that to save on weight and have concluded that a detour to the moon is the best route to Mars. Previous studies have suggested that lunar soil and water ice in certain craters of the moon could potentially be mined and converted to fuel. With the assumption that this tech exists at the time of a Mars mission, taking a detour to the moon to refuel actually reduces the mass of a mis...

Neutrinos scoop the 2015 Nobel Prize in Physics

Neutrinos have the smallest mass of any known particle, and are created in several ways, including during radioactive decay, directly in the Sun’s core, and when cosmic rays from the Sun hit the Earth’s atmosphere. Thousands of billions of neutrinos are streaming through our bodies each second. The prize has been awarded to two physicists who discovered a strange property of neutrinos, which Imperial scientists are still unravelling today. Today’s physics laureates, Professor Arthur B. McDona...

Scientists reveal birth date of earth’s inner core.

A reassessment of ancient rocks has led scientists to estimate that Earth's inner core started to form earlier than was previously thought, around 1.3 billion years ago. As it started to freeze, the core began generating a bigger magnetic field, which continues to today. Earth's active core contrasts sharply with that of our neighbor Mars, whose strong early magnetic field died around four billion years ago. Our planet's magnetic field is generated deep in the planet by the turbulent motion o...

Penn Research Simplifies Recycling of Rare-earth Magnets

Chemical technology can instantaneously separate elements and enable a smaller scale recycler. The latest news from researchers at the University of Pennsylvania is that they have pioneered a process that could enable the efficient recycling of two metals, neodymium and dysprosium. These elements comprise the small, powerful magnets that are found in many high-tech devices. Despite their ubiquity in consumer electronics, rare-earth metals are, as their name suggests, hard to come by. Mi...
