The Role of Money in Astronomy
So, all this astronomy I write about costs money to do. That isn’t a surprise to anybody, I hope. Everything in life has some cost to it, whether in money, karma, time, personal involvement, or ethical reward. While it is true that you can walk outside, look up, and do astronomy at the very basic level, to do anything beyond that requires equipment and person-hours. And those cost money.Amateur astronomy equipment can cost as little as the price of a book of star maps and a pair of 10×50 binoculars or run to many thousands of dollars or Euros or whatever units of money you use for a top-of-the-line home observatory. I always tell people to start small and let the love of astronomy guide them to whatever seems appropriate to spend.Professional astronomy is a whole different ball game. No one person “owns” a big observatory like Yerkes or Anglo-Australian or Mt. Wilson or Gemini or Hubble Space Telescope or the Very Large Array. They’re operated by consortiums of institutions based in a number of countries. It’s about the only way that the enormous costs of running state-of-the-art astrophysical research facilities can be afforded. And the costs can be … well… astronomical, running into multiple millions of dollars/Euros/etc. each year. The consortiums (and their countries) help pay the bills, and in return, each member of the consortium gets time on the instrument(s).
Recently the Gemini partnership was shaken when the United Kingdom announced it was pulling out to save money. I don’t know all the politics that led to this decision, but it took UK astronomers by surprise. The result of that pullout would have denied UK astronomers access to a major Northern Hemisphere observatory, starting nearly immediately.
It made little sense, but in times of tightening budgets, I suppose that the science and technology committee in the UK that made this decision didn’t see astronomy as being as important as other physics expenditures it wanted to make, or perhaps much less important than life sciences, for example. Nonetheless, it was a surprise to the partnership and a shock to the world’s astronomy community.
Today the Royal Astronomical Society announced that the UK is in “constructive discussions” to continue UK involvement in the Gemini Partnership. President of the RAS, Dr. Michael Rowan-Robinson commented, “The UK has invested about 35 million pounds in the capital phase of the Gemini Observatories, in which we have a 23% stake. To pull out precipitately, as seemed to be happening, would have written this off to make a saving of 4 million pounds a year, at the expense of inflicting great damage to the UK’s international reputation.”
That is a lot of money to invest, and UK astronomers had every right to feel betrayed by their government’s actions in the attempted pullout. Astronomy IS worth the money and the effort, and I suspect that UK scientists will need to make sure their collective voice is heard the next time somebody suggests “cost-saving” measures such as this one.
