You Were Here: Telling the Story of Cosmic Origins with the Habitable Worlds Observatory

Speaker

Jason Tumlinson | STScI / Johns Hopkins University

Abstract

HWO is envisioned as humanity’s life-finding super-Hubble, with the capacity to find and characterize dozens of Earth-like planets, searching for life. HWO will also possess the tools to revolutionize every aspect of frontier general astrophysics, from transient phenomena to the baryon cycle. This talk will highlight the astrophysics themes of HWO science, including key community contributed science cases. I will give my own perspective on how general astrophysics integrates with exoplanet science, concluding that astronomy has a unique role in answering some of humankind’s most profound questions about the Universe and our place in it.

UV Instrumentation: The Path to HWO

Speaker

Sarah Tuttle | University of Washington

Abstract

What will it take to have a UV spectrograph on HWO? What technologies will be needed — and what do we already have? This talk will cover the current state of UV technology, some of our key science drivers, and introduce challenges and next steps to motivate instrument development. This talk is accessible for all career stages and expertise levels — you don't have to be an UV instrumentalist to come hear what we're up to!

An illustration of Sun-like star HD 181327 and its surrounding debris disk. The star is at top right. It is surrounded by a far larger debris disk that forms an incomplete ellpitical path and is cut off at right. There’s a huge cavity between the star and the disk. The debris disk is shown in shades of light gray. Toward the top and left, there are finer, more discrete points in a range of sizes. The disk appears hazier and smokier at the bottom. The star is bright white at center, with a hazy blue region around it. The background of space is black. The label Artist's Concept appears at lower left.
