Our Night Sky When We Collide With Andromeda

In the photos above in order:

Present day
— 2 Billion years from now the of the approaching Andromeda galaxy is noticeably larger
— 3.75 Billion years, Andromeda fills the field of view
— 3.85 Billion years, the sky is ablaze with new star formation
— 3.9 Billion years, star formation continues
— 4 Billion years, Milky Way is warped and Andromeda is tidally stretched
— 5.1 Billion years, cores of both galaxies appear as a pair of globes
7 Billion years, the cores have merged, the bright core dominates the night sky

Here is an animation of the collision

In around 4 billion years our galaxy, The Milky Way, will collide with our neighbor galaxy Andromeda or M31. You might think this will be a catastrophic event for everything in the galaxy including our solar system but in reality most of the solar systems will simply pass by each other. However, the gas and dust between the stars will collide and eventually form new stars. Also, the orbits of those solar systems will be changed given the new galactic center(s) and the new mass pulling everything towards it and tossing them around.

The massive Andromeda galaxy is about 120,000 light years across while our galaxy is 100,000 light years across. Given their size, the speed that we our hurdling towards each other is relatively small at 250,000 miles per hour.

1.5 million more Americans would have jobs if not for Washington’s decision to pursue deficit reduction in the midst of a sluggish economy.


Unfortunately, news of successful deficit reduction is unlikely to result in any respite from new cuts or tax increases. The Obama administration still has its Social Security cuts on the table — as part of a potential “grand bargain” — and Congressional Republicans are gearing up to demand still more spending cuts in exchange for raising the debt ceiling.

Congress has tackled the deficit — at the cost of the economy (via wilwheaton)

First of all, I have a problem with politicians saying that they will make jobs, because it’s misleading. They will make jobs, but not jobs we want. They won’t make good, middle class jobs, they will make minimum wage jobs which can hardly support anyone. All the good jobs are disappearing because in order for companies to be competitive  they have to outsource as much as they can to countries that have almost no protection for their workers. Sir James Goldsmith predicted our economic situation almost perfectly nearly 2 decades ago in his book The Trap.

The bottom line is, if we want good jobs to return to the US, we need to end international free trade and give some incentives for companies to come back here. As it is, any company that doesn’t produce outside the US, will lose their shirts to their competitors.

People need to make F-hole roof lights. This is stunning.

This is what my dream house looks like.
