Astronomers using NASA's Hubble Space Telescope have measured the material along the Voyager 1 and 2 probes' trajectories as they move through space.

"Chase down."

The constellation of Virgo is especially rich in galaxies, due in part to the presence of a massive and gravitationally-bound collection of over 1,300 galaxies called the Virgo Cluster. 

This delicate blue group of stars — actually an irregular galaxy named IC 3583 — sits some 30 million light-years away in the constellation of Virgo (The Virgin).

The results have clear implications for galaxy formation, and also helps shed light on an ancient astronomical paradox - why is the sky dark at night?

The plasma balls, twice as massive as the planet Mars, are zooming so fast through space that it would take only 30 minutes for them to travel from Earth to the moon.

Researchers trace the previously unknown abundance of star-forming gas at different points in time, providing new insights into the “Golden Age” of galaxy formation, approximately 10 billion years ago.

The Hubble observations represent the first time such a three-body system, located 8,000 light-years away, has been confirmed.
