The circumgalactic and intergalactic media may contain the majority of baryonic matter in the universe, but their low density makes them extremely faint. Can an instrument designed to image low surface brightness objects help shed light on these ghostly structures?
A combination of infrared spectrograph and laser frequency comb provides unprecedented precisions in the hunt for habitable planets around nearby, cool stars.
Today’s authors use a new technique to make new discoveries about the Seven Sisters.
This year, the Chandra X-ray Observatory is celebrating its 20-year legacy. Dr. Ryan Hickox of Dartmouth College will explain how the resulting discoveries have shaped our view of the high-energy universe in his plenary talk at #AAS233.
Continuing on the thread from Friday’s post, I also attended the recent SPIE meeting. Here are my thoughts, as someone who is on the science side of the field, on the engineering and instrumentation conference.
If only we could image a planet as it transits in front of its host star, we could obtain data that would complement other observation techniques. Here we learn about a technique that might actually let us do so.
