Move over, Hope Diamond. The most famous gems on Earth have new competition in the form of a planet made largely of diamond, astronomers say.
The alien planet, a so-called "super-Earth," is called 55 Cancri e and was discovered in 2004 around a nearby star in our Milky Way galaxy. After estimating the planet's mass and radius, and studying its host star's composition, scientists now say the rocky world is composed mainly of carbon (in the form of diamond and graphite), as well as iron, silicon carbide, and potentially silicates.

Amazing glowing nebulas resembling cosmic candy take center stage in a group of new photos unveiled today (Oct 10) by the science team behind NASA's Chandra…Read More »
The pictures are part of a survey the Chandra space telescope is making of nearby planetary nebulas, which are formed when dying stars push off their outer gaseous layers. The first stage of this survey, which includes Chandra observations of 21 of these nebulas, has now been released. Chandra also released a video of the surveyed nebulas.

were treated to a spectacular light show.
This visible light image from the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite shows the northern lights swirling across Canada's Quebec and Ontario provinces. The city lights of Montreal also shine in the bottom of the image.
An intriguing spiral structure surrounding a pulsing red giant star may be offering a preview of how the sun will behave at the end of its life.
Using the Atacama Large Millimeter/Submillimeter Array (ALMA) in northern Chile, an international team of astronomers found the spiral structure, one never seen before, in the envelope of gas and dust around a red giant about 1,000 light-years from Earth and took a detailed three-dimensional reading of its composition.

U.S. House Rep. Paul Broun, a Georgia Republican, doesn't believe in evolution, the Big Bang theory, or the teachings of embryology. In fact, in a Sept.…Read More »
27 talk at Liberty Baptist Church in Hartwell, Ga., the member of the House Committee on Science, Space and Technology, who is also a medical doctor, called those areas of science "lies straight from the pit of hell."
But Broun also advanced his own theory of life on Earth.
The San Diego Zoo's newest giant panda cub got another checkup Tuesday (Oct. 9) and vets say he's about to sprout some baby teeth.
The 10-week-old cub weighed in at 7.3 pounds (3.3 kilograms) and measured about 20 inches (53 centimeters) from the tip of his nose to the tip of his tail. His development is right on track with other cubs born at the zoo and his chompers are coming in, vets said.
