International Ultraviolet Explorer was considered the most successful astronomical satellite ever. The human eye can perceive light with wavelengths between roughly 350 (violet) and 700 (red) nanometres. Ultraviolet light has wavelengths between roughly 10 nm and 350 nm. UV light can be harmful to human beings, and is strongly absorbed by the ozone layer. This makes it impossible to observe UV emission from astronomical objects from the ground. Many types of object emit copious quantities of UV radiation, though: the hottest and most massive stars in the universe can have surface temperatures high enough that the vast majority of their light is emitted
The Sun Is Often Out It was, however, the next single, "On and On” which would be the band’s breakthrough single; reaching No. 16 in the UK. With this momentum the album was released in April and shortly after "She Said" was re-released, also making it to No. 16 in the UK singles chart. The final single from the album "Lost Myself", narrowly missed out on giving the band a third successive Top 20 single, stalling at No. 22. "The Sun Is Often Out" was declared one of 1996's 50 best albums by both "Q" and "Melody Maker" and retains a favourable 4 star rating
