An international team of astrophysicists has discovered a galaxy 65 million light years away with so little dark matter that it may contain none at all.
When physicists at Fermilab smash particles together, most of what comes out of the collisions is well understood. But every once in awhile strange things appear in the data—incidents popularly known as zoo events.
Flags, arts and crafts from different nations, and a warm welcome transformed the DOE Brookhaven Site Office's Second Annual Unity Day into a celebration of people and cultures working together.
Stanford Linear Accelerator Center librarian Lesley Wolf needed a creative idea for the next library display. Ten-year-old Connor Reed had lots of free time this summer and an extensive set of K'nex, the flexible equivalent of Lego.
Although initial results were encouraging, physicists searching for an exotic five-quark particle now think it probably doesn't exist. The debate over the pentaquark search shows how science moves forward.
In creating neutrinos for the MINOS experiment at Fermilab, the NuMI focusing horn delivers batches of protons using intense magnetic fields generated by 200,000-ampere pulses of electric current.
