The future is bright for astronomy, and very expensive (op-ed)
Astronomy has a bright future.
The universe is being revealed in exquisite detail with the current generation of large optical telescopes, reaching back close to the big bang. There’s hope that the mysteries of dark matter and dark energy will be solved. Thousands of exoplanets have been discovered, and astronomers may be closing in on the first detection of life beyond Earth.
However, observations into the cosmic frontier involve extremely faint targets and astronomers are always hungry for more light. In order to keep peering farther into unknown reaches of the universe, the next generation of giant telescopes on the ground and in orbit will each cost billions of dollars.
