The discovery by NASA's Cassini mission at Saturn in 2005 of a large plume of material erupting from the south polar terrain of Enceladus, sourced within a subsurface ocean of salty liquid water laced with organic compounds, has brought together scientists from a diverse range of disciplines over the last decade to evaluate this small moon's potential for extraterrestrial life. The collection o...

High resolution spectra of novae after outburst reveal distinctive characteristics in the line profiles and intensities. The higher Balmer lines are often broader than the lower members of the series, and the relative profiles and intensities of the [O I] λλ6300, 6364 doublet differ from normal values. We suggest these features may be caused by the Quadratic Zeeman Effect from magnetic fields e...

Abstract A magnetic flux rope (FR), hosting hot plasma, is thought to be central the physics of coronal mass ejections. Such FRs are widely observed with passbands Atmospheric Imaging Assembly (AIA) on board Solar Dynamics Observatory that sensitive emission from plasma around 10 MK. In contrast, observations warmer (around 1 MK) counterparts sparse. this study, we report failed eruption a mult...
