MULTI-TASKING SUPERNOVA: RECORD-BREAKING STELLAR EXPLOSION HELPS UNDERSTAND FAR-OFF GALAXY
Press Release | 2012 August 29
A team, led by Edo Berger of Harvard University, made the most of a dying star’s fury to probe a distant galaxy some 9.5 billion light-years distant. The dying star is the most distant stellar explosion of its kind ever studied.
Gemini Observations Play Key Role in Testing Einstein’s Theories
Web Feature | 2012 August 28
A research used the Gemini North telescope to observe two white dwarf stars in a close gravitational embrace. The observations help confirm another ramification of Einstein’s General Theory of Relativity, which holds that the energy the pair loses in the shortened period is carried away in gravitational waves.
