More from Eyjafjallajokull

As ash from Iceland's Eyjafjallajokull volcano continued to keep European airspace shut down over the weekend, affecting millions of travelers around the world, some government agencies and airlines clashed over the flight bans. Some restricted airspace is now beginning to open up and some limited flights are being allowed now as airlines are pushing for the ability to judge safety conditions for themselves. The volcano continues to rumble and hurl ash skyward, if at a slightly diminished rate now, as the dispersing ash plume has dropped closer to the ground, and the World Health Organization has issued a health warning to Europeans with respiratory conditions. Collected here are some images from Iceland over the past few days.

Scenes from Sudan

Residents of the African nation of Sudan recently cast votes in the first national election in over 20 years. Official results are still forthcoming, but early indications show that President Omar Hassan al-Bashir is set to win a landslide victory. Opposition parties are threatening to boycott the results, as a statement from the U.S. White House described the election as plagued by "serious irregularities". Sudan remains a country with serious problems from conflict in Darfur and ongoing humanitarian crises in refugee camps and several drought-stricken regions. The election is also seen as prelude to another upcoming vote: a referendum of independence for Southern Sudan in 2011 that could create a new African nation. Collected here are recent photos from Sudan.

The southern former rebel Sudan People's Liberation Movement said it was also withdrawing from simultaneous parliamentary and state elections in all northern states except the disputed Blue Nile and south Kordofan districts, after its candidate, Yasser Arman, pulled out of the presidential race.

Earth Day 2010

Two days ago, was Earth Day, since 1970 it's been a day set aside to remember and appreciate the Earth's environment, and all of our roles within it. As a way to help appreciate and observe our environment, I've collected 39 recent images here, each a glimpse into some aspect of the world around us, how it affects and sustains us, and how we affect it. Here's hoping everyone had a great Earth Day yesterday.

Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer of our planet. Much of the information contained in this image came from a single remote-sensing device-NASA's Moderate Resolution Imaging Spectroradiometer, or MODIS.

Iceland's disruptive volcano

Days ago, British civil aviation authorities ordered the country's airspace closed as of noon, due to a cloud of ash drifting from the erupting Eyjafjallajökull volcano in Iceland. The volcano has erupted for the second time in less than a month, melting ice, shooting smoke and steam into the air and forcing hundreds of people to flee rising floodwaters. The volcanic ash has forced the cancellation of many flights and disrupted air traffic across northern Europe, stranding thousands of passengers. Collected here are photos of the most recent eruption, and of last month's eruptions, which were from the same volcano, just several miles further east.

All London flights, including those from Heathrow, will be suspended from noon (1100 GMT) today due to volcanic ash from Iceland that has already caused almost 300 cancellations here, officials said.

8. A natural-color satellite image shows lava fountains, lava flows, a volcanic plume, and steam from vaporized snow. The image was acquired on March 24, 2010, by the Advanced Land Imager (ALI) aboard NASA's Earth Observing-1 (EO-1) satellite. The lava fountains are orange-red, barely visible at the 10-meter (33-foot) resolution of the satellite. The scoria cones surrounding the fissure are black, as is the lava flow extending to the northeast. White volcanic gases escape from the vent and erupting lava, while a steam plume rises where the hot lava meets snow. (The bright green color along the edge of the lava flow is an artifact of the sensor.) (NASA's Earth Observatory/Robert Simmon)#
