Margaret Harris examines the circumstances that shaped the career of 1993 physics Nobel laureate Russell Hulse
Do clouds of in-falling gas lead to greater than expected inhomogeneity in the interstellar composition of our galaxy?
The Sun’s magnetic fields make its corona much hotter than the surface of the star. But how and why is still a mystery, as Philip G Judge explains
Understanding why the corona is so hot could help us predict space weather
Observation could explain a puzzling type of supernova
Careful numerical modelling explains origin of polarized light emitted by sodium atoms in the solar atmosphere
But what caused that dark spot to form in the first place?
Passive radar system offers energy and cost savings over existing methods
Heavy elements found in an ancient star lying on the fringes of the Milky Way were likely produced by a magneto-rotational hypernova explosion
Observation suggest that the Crab Nebula was created by a similar explosion
