Ancient light illuminates matter that fuels galaxy formation


 E-Mail
ITHACA, N.Y. - Using light from the Big Bang, an international team led by Cornell University and the U.S. Department of Energy s Lawrence Berkeley National Laboratory has begun to unveil the material which fuels galaxy formation.
There is uncertainty on the formation of stars within galaxies that theoretical models are unable to predict, said lead author Stefania Amodeo, a Cornell postdoctoral researcher in astronomy in the College of Arts and Sciences, who now conducts research at the Observatory of Strasbourg, France. With this work, we are providing tests for galaxy formation models to comprehend galaxy and star formation. ....

On December 1, 2020, the 900-tonne platform that held most of the instruments of the Arecibo Observatory (AO) at a height of more than 500 feet above the ground came crashing down. People from all walks of life, old and young, scientists and non-scientists, for whom this iconic telescope meant so much, have watched the footage of the collapse in disbelief. Soon after the collapse, students, scientists and the general public began a campaign to rebuild the AO. This is no surprise, as this observatory has been key in making groundbreaking discoveries in the areas of astronomy, planetary and atmospheric sciences, and, crucially, it has had far-reaching public outreach and science education progr ....
