No Brand-New Telescope Can Reshoot Jupiter's Storms From Ten Years Ago
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.
