Lunar dust can be a pain - but it’s also literally the ground we will have to traverse if we are ever to have a permanent human settlement on the Moon. In that specific use case, it’s clingy, jagged, staticky properties can actually be an advantage, according to a new paper, recently published in Research from researchers at Beihang University, who analyzed the mechanical properties of samples returned by Chang’e 6 mission to the far side of the Moon.

On Earth, aurorae are fleeting displays. They occur when charged particles from the Sun strike Earth's magnetosphere. Most of these particles are deflected away, but some particles become trapped and are directed toward the poles by magnetic field lines. They find their way into the upper atmosphere where they collide with atoms and molecules. This creates the energetic display in the sky, and the stronger the flow of charged particles from the Sun, the further the aurorae extend into middle latitudes.

Even when the idea of terraforming Mars was originally put forward, the idea was daunting. Changing the environment of an entire planet is not something to do easily. Over the following decades, plenty of scientists and engineers have looked at the problem, and most have come to the same conclusion - we’re not going to be able to make Mars anything like Earth anytime soon. A new paper available in pre-print on arXiv from Slava Turyshev of NASA’s Jet Propulsion Laboratory, is a good explainer as to why.

Finding Earth-like exoplanets with the composition and ingredients for life as we know it is the Holy Grail of exoplanet hunting. Since the first exoplanets were identified in the 1990s, scientists have pushed the boundaries of finding exoplanets through new and exciting methods. One of these methods is the direct imaging method, which involves carefully blocking out the host star within the observing telescope, thus revealing the orbiting exoplanets that were initially hiding within the star’s immense glare.

The central region of our Milky Way, sometimes referred to as the "Bulge," remains something of an enigma to astronomers. Because it is densely packed with stars and clouds of dust and gas, capturing images of its interior has historically been very difficult. But with advances in radio astronomy over many decades, which can capture light that is otherwise blocked at visible wavelengths, astronomers have made some immensely fascinating finds there. In addition to the well-known supermassive black hole (SMBH), Sagittarius A*, there is chemistry at work that could shed light on the origins of life in our galaxy.
