Subaru Telescope Detects the Mid-infrared Emission Band from Complex Organic Molecules in Comet 21P/Giacobini-Zinner
November 18, 2019
Using the Subaru Telescope, astronomers have detected an unidentified infrared emission band from comet 21P/Giacobini-Zinner in addition to the thermal emissions from silicate and carbon grains. These unidentified infrared emissions are likely due to complex organic molecules, both aliphatic and aromatic hydrocarbons, contaminated by N- or O-atoms...
The Whole Picture of Distant Supercluster in Three Dimensions
October 22, 2019
A team of astronomers used the Subaru Telescope and Gemini-North Telescope to reveal that a well-known distant supercluster is part of a larger structure at least twice as extended as what was already known. The galaxies associated with the supercluster are thought to have formed simultaneously over a vast area and then evolved to their observed states...
