Here we report our discovery of a band of blue luminescence (BL) in the Red Rectangle nebula. ... The spectrum of this newly discovered BL is most likely fluorescence from small neutral polycyclic aromatic hydrocarbon (PAH) molecules. ... If the carriers of this near-UV/blue fluorescence are PAHs, they are most likely neutral PAH molecules consisting of three to four aromatic rings such as anthracene (C14H10) and pyrene (C16H10). ...

... Our recent observations with the Hubble Space Telescope (August 29, 2014) led to revealing a highly isolated dwarf spheroidal galaxy KKs 3 situated at a distance of 2.12 0.07 Mpc from the Milky Way.
