Here is a good way to visualize the concept. Take an uninflated baloon and mark two dots on it witih a felt tip pen. Blow up the baloon. As the baloon expands, the two dots are not moving from their origional position, but they are moving away from eachother. This is much like what is happening as the universe expands.

For all you people who are saying there is no point we can use as a reference are wrong. We can infer the relative speed of our galaxy from the doppler shift of the cosmic microwave background radiation.

The Earth is moving at some 380 km/s towards the constellation Virgo.

The Virgo constellation is part of the milky way, therefore the solar system, let alone the earth, is not moving torwards it.

Actually virgo is a cluster of galaxies beyong the milky way.

This thread shows a profound lack of understanding of physics. The question "what is the speed we are actually moving with" is illogical if not accompanied with "in relation to this reference frame"!!! speed measurement is relative to a reference frame, you can not just measure speed.

Secondly, the universe expands, but we are not moving. There is no particular center, it just expands, like a balloon is filled with air.

There's a Virgo Cluster, which is the cluster of galaxies in your link.

And there's the Virgo Constellation, which is a group of stars in the milky way, actually some of them are less than 20 light years from the sun.

In your first post you said "constellation"
