ks ago NASA, America s space agency, announced that it would upgrade the
Hubble space telescope. It also has plans for a new device, dubbed the James Webb space telescope and
due to be launched in 2013. But modern ground-based telescopes can complement such observatories,
often achieving more and costing less. Mountaintop astronomy is entering a new golden era.

A possible particle of dark matter
WHEN Frank Wilczek, a Nobel laureate, proposed the existence of a new
type of elementary particle in 1977 he named it an “axion� after a type
of detergent, because it cleaned up a profound physical problem.
This problem is that the amount of visible stuff in the universe is far
smaller than is needed to account for the apparent effects of gravity. In
particular, galaxies behave as though they are much heavier than they
actually look.
One way of solving this conundrum is to invoke a type of matter that
has a gravitational field, but cannot interact with light or other forms of
electromagnetic radiation, and is therefore invisible. In other words,
dark matter. Axions ar fuel dispenser e the most popular proposal for what this dark
matter might actually be.
Unfortunately, they have since created a mess of their own. Many experiments have looked for axions.
Most have not found them. Indeed, they have proved so hard to detect that many physicists question
whether they exist.
Earlier this year, though, an Italian experiment did see something that suggested their existence. Now a
paper by Piyare Jain and Gurmukh Singh of the State University of New York, Buffalo, also offers some
evidence that axions really do exist. It is published in the January edition of the Journal of Physics G
Nuclear and Particle Physics.
The pair had another look at some photographic plates from an experiment conducted a d fuel dispenser
