Reporter Alexis Espinosa with the Dallas Morning News covered the discovery of five stars made by two Dallas high school students as members of an SMU summer physics research program. Called Quarknet, the program enabled the students to analyze data gleaned from a high-powered telescope in the New Mexico desert.

All five stars are eclipsing contact binary stars, pairs of stars that orbit around each other so closely that their outer atmospheres touch. As the stars eclipse, they dim and then brighten as one emerges from behind the other. These stars are categorized as variable stars, stars that change brightness, which make up half the stars in the universe. Continue reading

Hunt for dark matter takes physicists deep below earth’s surface, where WIMPS can’t hide

Dark matter makes up much of the universe, and surrounds us all like an invisible, clumpy soup. Physicists have hunted dark matter particles for decades, but they continue to elude observation.

Now construction of a major international experiment aimed at discovering dark matter could be constructed and operational by 2018, according to the SMU scientist on the experiment known as SuperCDMS SNOLAB. Continue reading
