As galaxies age, some of their basic chemical elements can also show signs of aging. This aging process can be seen as certain atoms “put on a little weight,” meaning they change into heavier isotopes — atoms with additional neutrons in their nuclei. Surprisingly, new surveys of the Milky Way with the National Science Foundation’s…

Green Bank Telescope Aids in Finding Lost Spacecraft

Finding a tiny lost space-craft at a distance of 270,000 miles away may seem impossible, but NASA scientists have done just that. Using a new radar technique, they have located India’s Chandrayaan-1 spacecraft which has been lost since August 2009, the last time any communication was received from it. Chandrayaan-1, India’s first mission to the…

01/05/2016: Physics Professor Using 3-D Map of the Milky Way to Determine Its Star Formation Rate

Radio telescopes have provided scientists with incredible information about our own galaxy, as well as those around us. While researchers understand a great deal of galaxies far away, gaps remain in the knowledge about our own, the Milky Way – specifically, how global star formation works in our own backyard, and how many stars our…

Pasadena News Now: Local High School Students Hunt for Pulsars

Hanaa is hunting for a blip in a vast set of data. Although she is only a high school student, she is searching for the signal of a pulsar — a rapidly rotating neutron star that emits a beam of electromagnetic radiation like a lighthouse. Hanaa and 19 of her fellow students at Alverno Heights…
