Did Andromeda crash into the Milky Way 10 billion years ago?

Our Milky Way smashed into its neighbouring Andromeda galaxy around 10 billion years ago, European astronomers suggest.


Previous studies have suggested that our galaxy is set to crash into Andromeda in 3-4 billion years, and that this will be the first time such a collision has taken place.

However, now a European team of astronomers led by Hongsheng Zhao of the University of St Andrews propose that the two star systems collided some 10 billion years ago and that our understanding of gravity is fundamentally wrong.

This would neatly explain the observed structure of the two galaxies and their satellites, something that has been difficult to account for until now, researchers said.

Flash floods, storm surges menace East Coast as Andrea meanders north

No longer a tropical storm, the weather system called Andrea was making its way up the East Coast, threatening flash floods and dangerous storm surges into Saturday as far north as Maine.

Andrea was wandering up the coast at about 35 mph Friday night, the National Weather Service said. That should give it plenty of time to drop heavy rain on New York and New England overnight and into Saturday afternoon before it scrapes Canada's Atlantic coast and trickles off into the Atlantic Ocean sometime Sunday.

Mauna Loa: minor unrest and inflation reported at planet’s largest volcano

July 6, 2013 – HAWAII – Very weak unrest in the form of inflation and seismic activity continues at the largest active volcano of our earth, which has not erupted since 1984. However, this activity is not strong enough to justify a raise of the alert level from green “normal” to yellow “unrest.” There is currently no sign that Mauna Loa will erupt any time soon. HVO reports in its monthly update: “Minor inflation of a shallow magma reservoir beneath Mauna Loa may be occurring. Seismicity rates were slightly elevated.
Deformation: Deformation of Mauna Loa continued to be dominated by southeasterly motion of the south flank. However, slow uplift also continues near the summit caldera (~1cm/yr at MLSP) suggesting that some inflation of the shallow magma reservoir complex beneath the summit area is occurring. –Volcano

LOS ANGELES –  Scientists say the deadly Arizona wildfire and other blazes raging across the West are becoming more common as the planet warms.

While no single wildfire can be blamed solely on climate change, researchers say hotter temperatures, prolonged drought and heavy undergrowth will increase the risk of more frequent and explosive fires.

Last month, officials at San Francisco International Airport hired a herd of part-time employees to toil on the west side of the property and engage in an unusual — but environmentally friendly — form of fire prevention.

Anyone looking down from a plane departing the airport may have wondered, What's with the goats?

The Watchers, 7/6/13, Adorali

Accoding to a World Meteorological Organization (WMO) report The Global Climate 2001-2010, A Decade of Extremes Earth experienced unprecedented high-impact climate extremes in 2001 - 2010 since the measurements began in 1850. In that period more national temperature records were broken than in any other decade.

The first decade of the 21st century was the warmest for both hemispheres and for both land and ocean temperatures. High temperatures were accompanied by a rapid decline in Arctic sea ice, and an accelerating loss of the ice sheets of the world's glaciers
