Tiny Dust Grains From Massive Stars: How the Smallest and Largest Are Linked Star dust is at the root of everything that exists, and is produced in large quantities around Wolf-Rayet binaries. But there are some puzzling observations of dust grain sizes that require explanations. New research shows why different observations have found different dust grain sizes.

Astronomers Devise a New Way to Measure Cosmic Expansion with Lensed Supernovae Researchers in Munich have used the Large Binocular Telescope in Arizona to capture five images of one and the same supernova in a single picture. The gravity of two foreground galaxies has deflected the light from a supernova far in the background along different paths to Earth.

How Saving Earth Could Ruin Orbit Satellite imaging is increasingly important to every field from crop monitoring to poverty reduction. So it’s no surprise that there have been more and more satellites launched to try to meet that growing demand. But with more satellites comes more risk for collision - and the debris field that comes after the collision. A new paper in Advanced in Space Research from John Mackintosh and his co-authors at the University of Manchester looks at how we might use mission design to mitigate some of the hazards of increasing the number of satellites even more

How to Weigh a Killer Asteroid at 22 Kilometers per Second Estimating a mass for a potentially hazardous asteroid (PHA) is perhaps the single most important thing to understand about it, after its trajectory. Actually doing so isn’t easy though, as the mass for objects in the tens to hundreds of kilometers in size are too small to have their mass calculated by traditional radio-frequency tracking techniques. A new paper from Justin Atchison of the Johns Hopkins University Applied Physics Laboratory and his co-authors proposes a method that could find the mass of asteroids even on the smaller end of that range, but will require precise coordination.
