Young stars sculpt gas 13.powerful outflows with This Hubble Space Telescope view shows one of the most dynamic and intricately detailed star-forming regions in space, located 210,000 light-years away in the Small Magellanic Cloud (SMC), a satellite galaxy of our Milky Way. At the centre of the region is a brilliant star cluster called NGC 346. A dramatic structure of arched, ragged filaments with a distinct ridge surrounds the cluster. A torrent of radiation from the hot stars in the cluster NGC 346, at the centre of this Hubble image, eats into denser areas around it, creating a fantasy sculpture of dust and gas. The dark, intricately beaded edge of the ridge, seen in silhouette, is particularly dramatic. It contains several small dust globules that point back towards the central cluster, like windsocks caught in a gale. Credit: NASA, ESA and A. Nota (ESA/STScI, STScI/AURA) “After my PhD I spent three years at the Space Telescope Science Institute which is responsible for all the science operations with Hubble. This was a very exciting time. Especially during a certain week in the year, the week right before the proposal deadline, when all astronomers write what amazing science they would like to do with Hubble. In Baltimore, where nearly everyone uses Hubble, this week is crazy. Getting time on Hubble is very hard. Only 1 out of every 8 proposals gets time. And it takes a lot of effort to write a proposal.   “The weeks before, the Institute seems to be buzzing. People are excited to discuss wild ideas, brainstorm with each other how the instruments can be used to get the most out of it. For many it is a very stressful period, where most people barely get any sleep. But the intensity and passion people have for their work is very hard to describe and it really struck me. “One of the better memories is of the colleague who would order many pizzas to support everyone who was still working on improving their proposals. If you realize how hard it is to get time and how competitive it is, it is very special to feel that supportive atmosphere in the Institute. People just want to amazing science with Hubble. That week they seem to give everything for it.” — Dr. Selma E. de Mink Assistant Professor University of Amsterdam Netherlands
