Yu et al. discovered radio bursts above a sunspot that resemble radio emissions from aurorae on Earth. The pink-purple streaks in this illustration represent the radio emissions, with higher-frequency radio signals in pink, closer to the sunspot, and lower frequencies in purple. The thin lines represent magnetic field lines above the sunspot. The sunspot is the dark region on the Sun at the bottom. Image credit: Sijie Yu, New Jersey Institute of Technology.

This two-part graphic shows evidence of a gaseous clump of helium in the halo surrounding galaxy GN-z11. In the top portion, at the far right, a small box identifies GN-z11 in a field of galaxies. The middle box shows a zoomed-in image of the galaxy. The box at the far left displays a map of the helium gas in the halo of GN-z11, including a clump that does not appear in the infrared colors shown in the middle panel. In the lower half of the graphic, a spectrum shows the distinct ‘fingerprint’ of helium in the halo. The full spectrum shows no evidence of other elements and so suggests that the helium clump must be fairly pristine, made of hydrogen and helium gas left over from the big bang, without much contamination from heavier elements produced by stars. Theory and simulations in the vicinity of particularly massive galaxies from these epochs predict that there should be pockets of pristine gas surviving in the halo, and these may collapse and form Population III star clusters.
