Shock Waves Power an Exploding Star

Roughly 50 times each year, a star nearing the end of its life accretes too much material from a close companion star and erupts in a violent display of light — shedding its outer surface and propelling shock waves into our galaxy — only to recover and smolder as it … Continue Reading →

There are great observatories – and then there are “Great Observatories,” a title given to four space telescopes launched in the 1990s/early 2000s, each studying a different wavelength of light. The Hubble Space Telescope, primarily looking at visible light, you are likely familiar with; it was the first launched and … Continue Reading →

GRB all-sky map

Back to School with GRB 101

Up until a few years ago, gamma-ray bursts (or GRBs, for short) were arguably the biggest mystery in high-energy astronomy. Basically, gamma-ray bursts are brief, extremely bright bursts of gamma-rays (as the name implies). They appeared at random across the sky. But what are they? What causes that burst? And … Continue Reading →

Gamma-ray Novae Cake

Science as Food
