How to observe a ‘black hole symphony’ using gravitational wave astronomy
Shrouded in mystery since their discovery, the phenomenon of black holes continues to be one of the most mind-boggling enigmas in our universe. In recent years, many researchers have made strides in understanding black holes using observational astronomy and an…
Nearly extreme black holes which attempt to regrow hair become bald again
The black holes of Einstein’s theory of relativity can be completely described by just three parameters: their mass, spin angular momentum, and electric charge. Since two black holes that share these parameters cannot be distinguished, regardless of how they were…
Images from NJIT’s big bear solar observatory peel away layers of a stellar mystery
An international team of scientists, including three researchers from New Jersey Institute of Technology (NJIT), has shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star’s upper atmosphere,…
Two cosmic peacocks show violent history of the magellanic clouds
Two peacock-shaped gaseous clouds were revealed in the Large Magellanic Cloud (LMC) by observations with the Atacama Large Millimeter/submillimeter Array (ALMA). A team of astronomers found several massive baby stars in the complex filamentary clouds, which agrees well with computer…
