Travel Through Time

In the early 1900s, Edwin Hubble made the startling discovery that our Milky Way galaxy is not alone. It is just one of many galaxies, or “island universes,” as Hubble dubbed them, swimming in the sea of space.

Now, a century later, NASA’s Galaxy Evolution Explorer is helping piece together the evolution of these cosmic species. Since its launch in 2003, the mission has surveyed tens of thousands of galaxies in ultraviolet light across nine billion years of time. The results provide new, comprehensive evidence for the “nurture” theory of galaxy evolution, which holds that the galaxies first described by Hubble – the elegant spirals and blob-like ellipticals — are evolutionarily linked.

Interesting article from 2004:

Eight years ago, American and British scientists who conducted investigations in Antarctica made a sensational discovery. US physicist Mariann McLein told the researchers noticed some spinning gray fog in the sky over the pole on January 27 which they believed to be just ordinary sandstorm. However, the gray fog did not change the form and did not move in the course of time. The researchers decided to investigate the phenomenon and launched a weather balloon with equipment capable to register the wind speed, the temperature and the air moisture. But the weather balloon soared upwards and immediately disappeared.
