Hubble data predicts Milky Way galactic collision When Galaxies Collide! It sounds like an early science fiction novel. However, analysis of Hubble measurements shows that our own Milky Way galaxy is moving toward a head-on collision with our nearest neighbor, the Andromeda galaxy (also known as M31). The collision will start in about four billion years, and over the following three billion years the two spiral galaxies will coalesce into a large elliptical galaxy. View all The story begins and ends with Hubble. Astrophotograph of M31, also known as the Andromeda nebula, taken using an 85mm telescope with a hydrogen-alpha filter to enhance nebulosity (Photo: Adam Evans) Hubble also demonstrated that the redshift of galaxies (first discovered in 1912 by Vesto Silpher) was proportional to their distance from our galaxy. Some 90 years later, we know that M31 is about 2.5 million light-years away, and is approaching our galaxy at about 109 km/sec. The end of the story also owes much to a different Hubble - the Hubble Space Telescope.

Total Solar Eclipse of November 14, 2012, as seen from a hilltop about 20 miles west of the Outback town of Mount Carbine, Queensland, along the Mulligan Highway (Peninsula Development Road), a road only paved in recent years. Heading inland to get away from coastal showers and clouds which were promising to interfere with the viewing, we drove some 150 miles into the outback to find a good spot the day before and settled upon a remote hillside, up along a dirt track that pulled away from the main road.
