What Would Happen if Someone Moved at Twice The Speed ​​of Light?

As far as we know, it’s not possible for a person to move at twice the speed of light. In fact, it’s not possible for any object with the kind of mass you or I have to move faster than the speed of light. However, for certain strange particles, traveling at twice the speed of … Read more

A Spacecraft Just Recorded The Lunar Eclipse Like You’ve Never Witnessed It Before

A total lunar eclipse is an incredible sight. As Earth passes between the Moon and the Sun, its shadow slips across the face of our satellite so only long, red wavelengths – sunlight refracted by Earth’s atmosphere – can slip through, tinting the usually pale Moon blood-red. That’s when we see it from here, on … Read more

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

One of The Hot, Dense Blobs Deep Inside Earth Has Been Revealed With New Imaging

For the first time, scientists have taken a proper look at an ultra-low velocity zone. These enigmatic pockets of rock sit close to the Earth’s core, about 3,000 kilometers (1,864 miles) below the surface. At that depth they’re obviously difficult to study, but we know they’re there because of the way seismic waves flow through … Read more

Mars Has Auroras Without a Global Magnetic Field, And We Finally Know How

Earth’s auroras are a glorious wonder, but our planet isn’t the only place in the Solar System where these phenomena can be found. An atmospheric glow, albeit sometimes in invisible wavelengths, has been spotted at every planet except Mercury, and even some moons of Jupiter… and even a comet. But Mars is where it gets … Read more

NASA’s Voyager 1 Is Sending Back Mysterious Data From Beyond Our Solar System

NASA’s Voyager 1 is continuing its journey beyond our Solar System, 45 years after it was launched. But now the veteran spacecraft is sending back strange data, puzzling its engineers. NASA said on Wednesday that while the probe is still operating properly, readouts from its attitude articulation and control system – AACS for short – … Read more

The Evolution of a Head Has Been Traced Back Surprisingly Far Back Our Ancestral Line

What’s in a head? According to new research, a little bit of our ancestors’ tails. In the early days of complex, multicellular life on Earth, animals started out without any spines or brains. They only had a network of neurons spread throughout their body. Over the course of millions of years, however, that system somehow … Read more

These Videos From a Space Probe Flying Past The Sun Are Truly Out of This World

A spacecraft looping around the Sun has made its first close approach – and filmed the encounter in glorious detail. The European Space Agency’s (ESA) Solar Orbiter entered the close encounter, known as perihelion, on 26 March, coming in at a distance of around 48 million kilometers (30 million miles), inside the orbit of Mercury. … Read more

Extraterrestrial Stone Found in Egypt May Be First Evidence on Earth of Rare Supernova

‘Standard candle’ (or type Ia) supernova explosions are some of the most energetic events in the Universe, happening when a dense white dwarf star subsumes another star. Now, scientists think they’re found the first evidence on Earth of such a supernova. The claim comes after a careful study of the extraterrestrial Hypatia stone that was … Read more

Potentially Alive 830-Million-Year-Old Organisms Found Trapped in Ancient Rock

An incredible discovery has just revealed a potential new source for understanding life on ancient Earth. A team of geologists has just discovered tiny remnants of prokaryotic and algal life – trapped inside crystals of halite dating back to 830 million years ago. Halite is sodium chloride, also known as rock salt, and the discovery … Read more
