Interstellar signals might be intermittent for many reasons, such as targeted sequential transmissions, or isotropic broadcasts that are not on continuously, or many other reasons. The time interval between such signals would be important, because se

Observing nearby galaxies would facilitate the search for artificial radio signals by sampling many billions of stars simultaneously, but few efforts have been made to exploit this opportunity. An added attraction is that the Milky Way is the second-

The so-called Fermi paradox claims that if technological life existed anywhere else, we would see evidence of its visits to Earth-and since we do not, such life does not exist, or some special explanation is needed. Enrico Fermi, however, never publi

The Ohio State University Radio Observatory recorded a strong, narrowband emission near the 21 cm hydrogen line in 1977 during a search for extraterrestrial intelligence, an event known as the "Wow" signal. The few independent attempts to replicate t

In 1977 a search for extraterrestrial intelligence at the Ohio State University Radio Observatory recorded a strong, narrowband, and apparently intermittent emission near the 21 cm hydrogen line. The detection displayed the antenna pattern signature

Since the inception of the U.S. DOE Hanford Site in 1943, numerous studies have been conducted on terrestrial wildlife. Onsite contractors have focused their attention on the role of wildlife in the uptake and transport of radionuclides. Graduate stu

The U.S. Department of Energy's Hanford Site was established in southeastern Washington during the 1940s to produce plutonium, and the Pantex plant in Texas (used to load conventional ammunition shells and bombs) was rehabilitated in the 1950s to ass
