Saturn's rings: The remains of an icy moon

James Edward Keeler’s work didn’t end all speculation about Saturn’s rings. For example, scientists still don’t know when they formed, but researchers are getting closer to understanding how they came to be.

Opening up space travel to everyone

Jason Marsh is done waiting around for someone else to transport him into space.

Marsh, a system administrator near Washington, D.C., is preparing to launch a new website for his Open Space Movement (OSM — currently here), a nonprofit project that aims to be a platform for developing and funding aerospace technology — and will be open to anyone who wants to join in.

Bids in space: When should we outsource government science?

Government research and development has its limits: Time, money and bureaucracy can all hamper the timely progress of research. As a result, many federal agencies are looking to private companies to help drive new innovation and keep costs down — but it’s never that simple. Two current hot-button topics — returning humans to space and geoengineering — highlight a range of issues related to how private and public investment in science can coexist. This month, we focus on NASA.

Hubble's pics of Pluto: Dark orange and charcoal-black

Blogging on EARTH

Today NASA released new Hubble images of dwarf planet Pluto — and far from being just an icy colorless rock, the images show a mottled, dynamic, orangey-black world that changes color with the seasons (on Pluto, the change of seasons lasts 248 Earth years — and although on Earth the seasons change due to the axial tilt of the planet, Pluto's eccentric, non-circular orbit plays a big role in its seasonal variations).

Benchmarks: February 4, 1962: Five planets align - but no end of the world

In the movie "2012," released in theaters last November, an alignment of five planets in our solar system — supposedly foretold by the Mayans thousands of years ago — causes horrors that span nearly every earth science disaster movie cliché: solar flares, neutrinos, earthquakes, volcanoes, floods, poles shifting, oceans washing over the tallest mountains in the world, cities falling into the sea, mass hysteria and, basically, total destruction of life as we know it.

On Her Majesty's space agency

The United Kingdom is to have its own dedicated space agency, U.K. Minister for Science Lord Paul Drayson announced last month. Supporters of the U.K. space program hope the agency, which will coordinate all of Britain’s space activities, will not only bring more jobs and income but will also increase the profile of the space program.

Exoplanet forecast: Quartz with a chance of feldspar

Next time you’re unhappy with the weather, be glad it’s not raining rocks. That seems to happen on CoRoT-7b, a hot, Earth-like planet about 500 light-years away from us. A new modeling study suggests that the exoplanet’s atmosphere is filled with the chemical components of rock, such as oxygen, sodium and silicon monoxide, and whenever these gases condense into clouds, rocky rain likely hammers down onto CoRoT-7b’s sweltering surface.

Crystal Ball EARTH: Space: NASA keeps watch on a changing planet

In 2009, we saw a number of changes on Earth. The average global ocean surface temperature last summer was the warmest on record. Thin seasonal ice has recently replaced thick older ice as the dominant type of ice in the Arctic. And scientists saw that despite a quiet sun with few sunspots, Earth can continue to be bombarded with a high level of solar energy.

Down to Earth With: Buzz Aldrin

On July 20, 1969, Apollo 11 astronauts Buzz Aldrin and Neil Armstrong made history when they landed and walked on the moon. The voyage left a lasting impression on Aldrin, who, at the age of 79, is one of the most vocal supporters of human space exploration.
