A spacecraft just recorded a lunar eclipse like you’ve never seen it before

The total lunar eclipse is an incredible sight. As Earth passes between the Moon and the Sun, its shadow slides across the face of our satellite, so only long red wavelengths—sunlight refracted from Earth’s atmosphere—can creep in, coloring the moon’s usually pale color blood red. That’s when we see it from here, on our planet. …

First patient injected with experimental cancer-killing virus in a new clinical trial

An experimental cancer-killing virus has been administered to a human patient for the first time, with the hope that testing will eventually reveal evidence of a new way to successfully fight cancer tumors in people’s bodies. The candidate drug, called CF33-hNIS (also known as Vaxinia), is a so-called oncolytic virus, a genetically modified virus designed …

In a wild development, physicists have revived an alternative theory of gravity

In the dark depths of space, our models of the universe become chaotic. A new study looking at the super-diffused dwarf galaxy AGC 114905 has revived a controversial theory (or more accurately a hypothesis) about gravity, giving us more questions than answers about what makes our galaxies move. It all starts with dark matter – …

One of the dense and hot spots in the depths of the Earth has been revealed with new imaging

For the first time, scientists have taken a proper look at an extremely low velocity region. These mysterious pockets of rock lie near the Earth’s core, about 3,000 kilometers (1,864 miles) below the surface. It’s obviously difficult to study at this depth, but we know they exist because of the way seismic waves flow through …

Mars has auroras without a global magnetic field, and we finally know how

The aurora borealis on Earth is a wonderful wonder, but our planet is not the only place in the solar system where these phenomena can be found. An atmospheric glow, albeit sometimes with invisible wavelengths, has been observed on every planet except Mercury, and even some of Jupiter’s moons… and even a comet. But Mars …

NASA’s Voyager 1 sends mysterious data from outside our solar system

NASA’s Voyager 1 continues its journey outside our solar system, 45 years after its launch. But now, the veteran spacecraft is sending out strange data, baffling its engineers. NASA said Wednesday that while the probe is still operating properly, the readings from the Expression and Attitude Control System — AACS for short — do not …

The evolution of the head has been surprisingly traced far from our ancestors’ line

What is in the head? According to new research, a bit from our ancestors’ tails. In the early days of complex, multicellular life on Earth, animals began without any spines or brains. They just had a network of neurons scattered throughout the body. However, over the course of millions of years, this system has somehow …

These videos from a space probe flying through the sun are really out of this world

A spacecraft orbiting the sun made its first close approach – and captured the encounter in great detail. The European Space Agency’s (ESA) Solar Orbiter entered the close encounter, known as perihelion, on March 26, coming at a distance of about 48 million kilometers (30 million miles), inside Mercury’s orbit. At this proximity, temperatures reached …

A new type of ‘solar’ cell shows we can generate electricity even at night

Conventional solar technology absorbs incoming sunlight to strike voltage. Oddly enough, some materials are able to go in the opposite direction, to produce energy because they radiate heat back into the cold night sky. A team of engineers in Australia has now shown the theory in action, using the type of technology commonly found in …
