a jetted explosion releases the gamma-ray radiation that makes a GRB, followed by a longer-lived afterglow. A day later, the radioactive material that was expelled in all directions during the
— Dead star 'glitches' could reveal the origins of fast radio bursts — The heaviest neutron star ever observed is shredding its companion However, if some massive stars are collapsing completely into black holes without supernova explosions, then they cannot contribute to the creation and...

The radioactive decay of these unstable nuclei also powers a rapidly evolving, supernova-like transient known as a "kilonova" (also known as "macronova"). Kilonovae are an approximately isotropic electromagnetic counterpart to the GW signal, which also provides a unique and direct probe of an ...
Therefore, conservationists have long waited for an effective idea to take down the rhino horn black market. Radioactive Rhino Horns The idea is simple: drill tiny holes into still-attached rhino horns, hammer radioactive chips in, and spray thousands of microdots on the outside for further ide...
In what way do the radioactive isotopes 31P and 32P differ? What are the effects of the rotation of a galaxy on its spectral lines? What is the difference between classical, special, and general relativity? Why didn't the planets become stars, assuming that they condensed out of the s...
An illustration of a quasar blasting a jet of hot, radioactive wind into the cosmos. (Image credit: © NASA, ESA and J. Olmsted (STScI)) At the center of almost every galaxy in the universe is a supermassive black hole gobbling up incredible amounts of matter, and belching out ...
research on HED plasmas can help us understand how to makeradioactiveisotopes. These radioisotopes have many practical applications. For example, they can be used to create images of the inside of our bodies for understanding medical issues, or in industry for understanding how materials wear out ...
“Radioactive” On a lighter note, the National Atomic Testing Museum in Las Vegas is a contender in the second International “When You Work at a Museum” Dance Off Contest, “Electric Boogaloo”. Closes with the music of Tom Lehrer… “We’ll All Go Together When We Go.” http://...
