CANDELS Team Discovers Dusty Galaxies At Ancient Epoch With Hubble Space Telescope; Tracks Build-Up Of Star- And Planet-Forming Material


Dust is an annoyance in everyday life, but an important building block of stars and planets. As such, astronomers need to understand how cosmic dust forms over time — it’s an integral step in figuring out the evolution of galaxies, and the stars and planets within them.

To better understand cosmic dust, University of Texas at Austin assistant professor Steven Finkelstein and colleagues are pursuing one of the largest Hubble Space Telescope projects to date, studying dust in thousands of galaxies over a wide range of cosmic time. They published some early results in a paper lead by Finkelstein in a recent issue of The Astrophysical Journal.

“We don’t yet understand how galaxies build up their dust reservoirs,” Finkelstein said. “We know that dust builds up through time, but exactly when the formation of dust begins is unknown.”
