Why NASA"s SPHEREx mission will make "Most colorful" cosmic map ever
NASA's SPHEREx mission won't be the first space telescope to observe hundreds of millions of stars and galaxies when it launches no later than April 2025, but it will be the first to observe them in 102 colors......»»
A novel state of thorium opens the possibility for a nuclear clock
Why are there atomic clocks but no nuclear clocks? After all, an atom's nucleus is typically surrounded by many electrons, so in principle it should be less susceptible to outside noise (in the form of light). A nucleus, for high-atomic number atoms,.....»»
