    Star light, star bright, baby stars blow rings alight
    An artist’s rendering of the molecular cloud core of MC 27 based on observations from the ALMA telescope. The protostar and the disk surrounding it are shown in the lower right, with warm gas extending outward in a ring-like structure, with magnetic field lines penetrating the interior of the ring.

    The impulsive phase of the solar flare, in which most energy is released. Panel (a) a snapshot of Hα + 1.0 Å image showing post-flare brightening associated with coronal rain. The white box marks the ROI where the brightenings occurred. Panel (b) the zoomed-in view of the ROI marked by the white box in panel (a). The slits, with different colors, mark where the brightenings’ cross-sectional width were measured. Panel (c) the pseudo Dopplergrams (with red corresponding to red shift) of the ROI. Panels (d–g) the normalized Hα + 1.0 Å intensity profiles along the slits and the Gaussian fits. For reference, the color of each profile is the same as the color of the slit (see panel b). The Gaussian FWHM and ±3σ are provided in the panels. Credit: NJIT
