Dangerous Worlds
Elizabeth Tasker, Japan Aerospace Exploration Agency
In exploring our own solar system, astronomers have uncovered some weird worlds. However, these are nothing compared to the lands harboured by our neighbouring stars. Huge Jupiters snuggle so close to their star that their years last only as long as our days. Planets are resurrected around stars that have long been dead. Other worlds begin their nights with dual sunsets, like Tatooine in Star Wars, drown in global water oceans, as in Interstellar, or even have seas of tar. These worlds can be more extreme than anything in fiction and prompt us to ask if any could be called home.
NOTE: There were some sound problems with the recording. The auditorium was upgraded during the week before this event, and a couple bugs were uncovered during this field test of the system. We apologize, and the staff is working to ensure these problems are solved for future events.
Host: Dr. Frank Summers
Recorded live on November 7, 2017 at the Space Telescope Science Institute in Baltimore, MD USA

This video compares the colorful Hubble Space Telescope visible-light image of the core of the Lagoon Nebula and a Hubble infrared-light view of the same region.
This visible-light image of the central region of the Lagoon nebula reveals a fantasy landscape of ridges, canyons, pillars, and mountains of gas and dust surrounding a very hot newborn star. When the visible view crossfades into an image taken in near-infrared light, the most obvious difference is the abundance of stars that fill the field of view. Most of them are more distant, background stars located behind the nebula itself. However, some of these pinpricks of light are young stars within the Lagoon Nebula. Only the densest of the gas clouds remain in the infrared view.
