Simulations explore the properties of the leading edge of coronal mass ejections; this bright feature is one of the three structural parts commonly seen in these solar eruptions.
A search for the dense star clusters that inhabit the innermost regions of a galaxy finds 325 galaxies with this type of cluster, including 33 galaxies classified as ultra-diffuse galaxies.
