Over 20 years ago, Carnegie astronomer emeritus Alan Dressler chaired the Association of Universities for Research in Astronomy (AURA) Hubble Space Telescope (HST) and Beyond Committee. The group's work has been awarded the 2017 Carl Sagan Memorial Award presented at the meeting of the American Astronautical Society.
It isn’t often that our Capital Science Evening speaker hints at soon-to-be-breaking news right from the stage.
Tuesday night, Pierre Cox, Director of the Atacama Large Milimiter/submillimeter Array, a collection of 66 radio telescopes commonly known as ALMA, let the audience know that his organization would be releasing hot news about ancient galaxies the following day.
Or, rather, cold news.
New work from a joint team of plant biologists and ecologists has uncovered the factor behind an important innovation that makes grasses—both the kind found in native prairies and the kind we’ve domesticated for crops—among the most-widespread plants on the planet. Their findings may enable the production of plants that perform better in warmer and dryer climate conditions.
Rock samples from northeastern Canada retain chemical signals that help explain what Earth’s crust was like more than 4 billion years ago, reveals new work from Carnegie’s Richard Carlson and Jonathan O’Neil of the University of Ottawa. There is much about Earth’s ancient crust that scientists don’t understand. This is because most of the planet’s original crust simply isn’t around any longer to be studied directly—it has either sunk back into the planet’s interior due to the action of plate tectonics or been transformed by geological activity at Earth’s surface to make new, younger rocks.
New work from a team including Carnegie’s Guoyin Shen and Yoshio Kono used high pressure and temperature to reveal a kind of “structural memory” in samples of the metal bismuth, a discovery with great electrical engineering potential.
Baltimore, MD—A first-of-its-kind study on almost 20,000 K-12 underrepresented public school students shows that Project BioEYES, based at Carnegie’s Department of Embryology, is effective at increasing students’ science knowledge and positive attitudes about science. Younger students had the greatest attitude changes. The study covered five years and tested students before and after the one-week BioEYES program.
New remote sensing maps of the forest canopy in Peru identify new regions for conservation effort. Greg Asner and his Carnegie Airborne Observatory team used airborne laser-guided imaging spectroscopy, to identify preservation targets by undertaking a new approach to study global ecology—one that links a forest’s variety of species to the strategies for survival and growth employed by canopy trees and other plants.
Supernovae are cosmic explosions where a single star can become as bright as a billion stars combined. Even though supernovae are crucial to the Universe, including producing the elements...
Dr. Ostrander’s team has taken advantage of naturally occurring variations in dog populations in order to reveal the genetic mechanisms underlying both simple and complex traits. She will show how...
The formation of galaxies like our Milky Way involves gravity, dark matter, gases, star formation, and stellar explosions. Theoretical astrophysics is now revealing this complex process by using...
