These dusty disks, likely created by collisions between leftover objects from planet formation, were imaged around stars as young as 10 million years old and as mature as more than 1 billion … Continue reading It’s Complicated: Hubble Survey Finds Unexpected Diversity in Dusty Discs Around Nearby Stars
