Big galaxies didn't start out big. Hubble and Gaia teamed up to precisely measure 39 star clusters buried deep in the Milky Way, revealing the fossil remains of a small galaxy called LKH that our galaxy swallowed roughly 11.8 billion years ago. SORABUMI explains the evidence that galaxies grow by eating their neighbors.
Launch the best telescope in the world today, and you still can't photograph Jupiter as it looked a decade ago. Hubble, working since 1990, caught something no new instrument ever could: the outer winds of the Great Red Spot speeding up by as much as 8% between 2009 and 2020. SORABUMI explains why a telescope's worth isn't measured by how new it is, but by how long it has been watching.
The James Webb Space Telescope and the Hubble Space Telescope observed Saturn at nearly the same time. What infrared and visible light each uncovered tells us something profound about how planets are built.
