Hubble faces looming end as battery power fades
Scientists gather at the Space Telescope Science Institute in Baltimore to decide how to allocate dwindling Hubble observing time as battery and gyroscope limits threaten the telescope. NASA could send robots to replace components, extending life into the next decade, while prioritizing established programs like the continued study of Supernova 1987A.

Gradual Global Cooling Over Millions of Years Reshapes Climate
A Nature study led by Christina Ravelo and UC Santa Cruz colleagues shows Earth cooled gradually over about 35 million years with regional shifts in climate rather than a single catastrophe. Ocean sediment isotopes reveal a protracted transition, with tropical regions staying warm for about a million years after glaciation began in higher latitudes.
