This would cause the part of dark matter made of neutrinos to be smeared out and unable to cause the large galactic structures that we see.

This telescope is used to study galactic structure, stellar spectra, asteroid studies, supernovae, and to photograph heavy bodies.

Professor Mayor's research interests include extrasolar planets (also known as exoplanets), instrumentation, statistical properties of double stars, globular cluster dynamics, galactic structure and kinematics.

He was a pioneer in the study of galactic structure.

He measured radial velocities and studied spectroscopic binaries, and performed the first detailed analysis of galactic structure.

This could be primarily particles of small mass, giving them the gravitational power to affect the shape of galactic structures.

Scientists said the data may yet yield clues to conditions leading to the creation of galactic structure.

As one case in point, the string theory for the origin of galactic structure is illustrated with noodles in a Japanese restaurant.

They are mainly observed in young galactic structures such as open clusters, the arms of spiral galaxies, and in irregular galaxies.

These clumps merged and collided, consolidating into the large galactic structures seen today.
