How was the universe reionized? Cosmic sunbursts provide hints
How does the radiation that caused reionization travel out of galaxies? Studying a strongly-lensed system called the Sunburst Arc could tell us more.
Peering through the lens of the Milky Way Supermassive Black Hole
One of the most important observations by the next generation of giant telescopes will be made by pointing towards the Supermassive Black Hole at the center of our galaxy.
