SN 1993J was the closest core-collapse supernova
to have occurred this century and observable from the north. ING telescopes
immediately set in motion an extensive programme of astrometric, photometric
(UVBRI) and low- and high- dispersion spectroscopic
monitoring. The INT spectrum of SN1993J obtained one day after the discovery
was the first recorded anywhere at any wavelength. A public on-line archive
consisting of optical photometric and spectroscopic
data is offered to the community. Over 70 sites worldwide have availed
themselves of this unique facility [more

By observing distant type Ia supernovae, astronomers
determine that the universe is expanding at an accelerating rate - an
observation that implies the existence of a mysterious, self-repelling
property of space first proposed by Albert
Einstein, which he called the cosmological constant. This extraordinary
finding is named by the journal 'Science' as Breakthrough of the Year for
1998 [more] |
