How do you cool down a phoenix? I don’t mean the mythological birds of flame and rebirth, but rather a cosmic namesake with a fittingly fiery nature. Using the James Webb Space Telescope (JWST), astronomers may finally have the answer. They used the powerful instrument to investigate the extreme cooling of gas in the Phoenix … Read more

The Dutchman has been in red-hot form lately, with five goals in his last five league games, including a hat-trick in the Cherries’ 5-1 thrashing of Newcastle in January. 5 Justin Kluivert has 11 Premier League goals … Read more
In our analysis of the expansion-induced hyperfine entanglement of the hydrogen atom, we use the standard Hamiltonian for the hyperfine structure of the ground-state atomic hydrogen. This involves introducing the electron spin operator \(\hat{S}\) and the proton spin operator \(\hat{I}\). Therefore, the effective Hamiltonian for the ground-state hyperfine structure can be expressed as \({H}_{HF}=A\hat{S}\cdot \hat{I}\). … Read more
Planets can differ from the swirling envelopes of gas and dust from which they are born, astronomers have found. The revelation seems to indicate that the planet formation model favored by scientists may be overly simple. A team led by researchers from Northwestern University in Illinois made this discovery while observing a still-forming planet and … Read more
