The observation reveals high-energy X-rays that could help solve a mystery regarding the Sun’s corona.

As a new series of NASA observations show, there’s a lot more to sunlight than meets the eye.

This hidden light could help solve a mystery related to our host star’s incredibly hot outer atmosphere, the corona.

Ever wondered what our solar system might be like with an earthlike planet —- or one even five or six times larger —- orbiting between Mars and Jupiter?

Conventional theory has long held that the gravitational influence of Jupiter would have ripped any terrestrial mass planet to shreds or never allowed it to form there at all. But a new paper just accepted for publication in The Planetary Science Journal argues that a “hypothetical planet” ranging from one to ten earth masses located between the orbits of Mars and Jupiter would wreak havoc on our inner solar system within a timeframe of only a few million years.

There’s been much speculation about whether the solar system could safely harbor an additional planet between Mars and Jupiter where most of our asteroids are located, Stephen Kane, a planetary astrophysicist at the University of California in Riverside and the paper’s lead author, told me via email. This study shows how such a planet would destabilize planetary orbits, he says.

Kilonova explosions created when neutron stars collide and merge are perfectly spherical, not flattened discs as previously expected, a new study suggests.

The James Webb Space Telescope (JWST) is still doing its job — and doing it very well. Released today, this image shows the arms of barred spiral galaxy NGC 1,433 teeming with young stars that can be seen affecting the clouds of gas and dust around them. The image was taken as part of the Physics at High Angular resolution in Nearby Galaxies (PHANGS) collaboration, of which more than 100 researchers around the world are a part.

One of the James Webb Space Telescope’s first science programs is to image 19 spiral galaxies for PHANGS with its Mid-Infrared Instrument (MIRI), which is capable of seeing through gas and dust clouds that are impenetrable with other types of imaging.

David Hilbert was a great leader and spokesperson for the discipline of mathematics in the early 20th Century. But he was an extremely important and respected mathematician in his own right.

Like so many great German mathematicians before him, Hilbert was another product of the University of Göttingen, at that time the mathematical centre of the world, and he spent most of his working life there. His formative years, though, were spent at the University of Königsberg, where he developed an intense and fruitful scientific exchange with fellow mathematicians Hermann Minkowski and Adolf Hurwitz.

Sociable, democratic and well-loved both as a student and as a teacher, and often seen as bucking the trend of the formal and elitist system of German mathematics, Hilbert’s mathematical genius nevertheless spoke for itself. He has many mathematical terms named after him, including Hilbert space (an infinite dimensional Euclidean space), Hilbert curves, the Hilbert classification and the Hilbert inequality, as well as several theorems, and he gradually established himself as the most famous mathematician of his time.

Scientists of the University of Antwerp and University of Liège (Belgium) have found how the human brain changes and adapts to weightlessness after being in space for six months. Some of the changes turned out to be lasting—even after eight months back on Earth. Raphaël Liégeois, soon to be the third Belgian in space, acknowledges the importance of the research “to prepare the new generation of astronauts for longer missions.”

A child who learns not to drop a glass on the floor, or a tennis player predicting the course of an incoming ball to hit it accurately are examples of how the brain incorporates the physical laws of gravity to optimally function on Earth. Astronauts who go to space reside in a weightless environment, where the brain’s rules about gravity are no longer applicable.

A new study on brain function in cosmonauts has revealed how the brain’s organization is changed after a six-month mission to the International Space Station (ISS), demonstrating the adaptation that is required to live in weightlessness. The findings are published in the journal Communications Biology.

The “China Compound Eye” radar array aims to track and characterize potentially threatening deep-space objects.

Scientists from The Ohio State University have a new theory about how the building blocks of life—the many proteins, carbohydrates, lipids and nucleic acids that compose every organism on Earth—may have evolved to favor a certain kind of molecular structure.

It has to do with a concept called chirality. A geometric property inherent to certain molecules, chirality can dictate a molecule’s shape, chemical reactivity, and how it interacts with other matter. Chirality is also sometimes referred to as handedness, as it can be best described as the dichotomy between our hands: Though they are not identical, the right and the left hand are mirror images of each other, and can’t be superimposed, or exactly overlaid on one another.

In the journal ACS Earth and Space Chemistry, researchers now propose a new model of how the molecules of life may have developed their “handedness.”
