An epic environmental tragedy has been unfolding in the past week and a half, with things going from bad to worse to terrible (and it's not over yet). What I'll do here is take a quick look at what happened so far, and then look at what you can do to help.
Slideshow: Amazing Photography of the Gulf Oil Spill
Tuesday, April 20, 2010
The Deepwater Horizon, a semi-submersible offshore drilling rig in the Gulf of Mexico, exploded and caught fire at around 10 p.m. local time (CST). 126 people were on board, 17 were injured and 11 are still missing (presumed dead).

Most of the survivors escaped using lifeboats and were picked up by a supply boat that BP had hired. The survivors were brought to Port Fourchon to go through a medical check-up and be reunited with their families.

On April 22, officials stated that the 11 missing workers could have been near the blast and not been able to escape. After having been on fire for more than a day and leaving behind a plume of smoke more than 30 miles long that could be seen from space, Deepwater Horizon sank on April 22, 2010

On Saturday, April 24, it was discovered that the underwater "riser" structure that connects the rig with the well was damaged and oil was leaking into the ocean. At first it was estimated that 1,000 barrels a day were being dumped into the Gulf of Mexico's ecosystems.
Monday, April 26, 2010
Search-and-rescue operations have been suspended with 11 people still missing. Officials warn that the leaks could take "months" to fix, even with the use of sophisticated underwater robots.

The U.S. Coast Guard is considering setting fire to the oil to keep some of it from reaching the sensitive ecological areas on the shores. This is a tough decision, as there are pros and cons to each course of action. They set fire to a pocket of the oil, but not on a large scale.

It is discovered that the leak is not spewing the equivalent of 1,000 barrels of oil per day, but rather 5,000 (and some even estimate it at 10,000 barrels/day using satellite images). By end of day, the oil slick has reached the Mississippi Delta.

The slick was estimated, as of April 30, to cover 6,000 square miles, or an area approximately equivalent to that of Jamaica. It was so close to New Orleans that many local residents reported that they could smell the oil: The Times-Picayune reports that the city has been overwhelmed by a "pungent smell."

SkyTruth, a small non-profit, analyzed radar and satellite imagery and estimated that the oil was leaking much faster than the original official estimates. The initial figure was 1,000 barrels/day, which they successfully challenged with a new estimate of 5,000 barrels/day. But even that proved too optimistic, and on Saturday they revised their estimate to 25,000 barrels/day!
Also on Saturday, Rush Limbaugh said on his radio show that "maybe" the oil rig explosion was an act of eco-terrorism. Forget facts, why blame the people responsible when you can make up stories that allow you to blame people you don't like?

BP is trying to install a shutoff valve on one of the three underwater leaks, but this is a complicated operation that might not succeed. National Oceanic and Atmospheric Administration said the oil slick appears to be drifting toward the Alabama and Florida coasts, including the Chandeleur Islands off Louisiana's southern tip.
It's also important to look at the impact of the oil spill on the critically endangered bluefin tuna population that spawns in the Gulf of Mexico.
