The IndependentNASA Telescope Captures Bright Heart of Spiral Galaxy 45 Million Light-Years Away
A new image from NASA’s Webb Space Telescope shows the brilliant core of Messier 77, a barred spiral galaxy in the Cetus constellation. The galaxy’s active nucleus is powered by a supermassive black hole 8 million times the mass of the sun. The mid-infrared instrument revealed de…
Science NewsPhysicists Use Particle Physics Link to Study Hawking Radiation
Researchers have applied a mathematical connection known as the double copy to translate Hawking radiation from general relativity into the language of the standard model of particle physics. The approach equates the radiation to a charged particle scattering off a collapsing sph…
