First Paper from Gemini/HST Galaxy Survey: It Takes More Than Aging to Shape A Galaxy

Can galaxies observed at very high redshifts (at a time when the universe was a fraction of its current age) evolve to look like today's nearby galaxies simply by growing older? The answer is no according to an international team of scientists led by Inger Jørgenson (Gemini Observatory) who used GMOS on Gemini North, combined with HST imaging data to survey distant galaxies and chart their evolution.

100th Gemini Paper Reveals White Dwarf Progenitors are Prolific Mass Expellers

A long-standing problem in understanding the evolution of stars has been determining the nature of the stellar progenitors for white dwarf stars. In particular, astronomers want to know how a rather massive star (up to seven times the mass of the Sun) can lose enough mass to become a white dwarf. Key questions include: Which main-sequence stars eventually end their life as white dwarfs? How much mass do they lose in late evolutionary stages? What process allows this to occur?

Journey Through The Universe

A Gemini partnership with Mauna Kea Observatories, the Hawaii Department of Education and the Challenger Center for Space Science Education will bring the program Journey Through the Universe to several East Hawaii communities. This program will provide educators, students and the public with exciting educational experiences and share the discoveries from Mauna Kea and our exploration of the universe.
