Quantum Oddity: Photons Appear to Exit an Atomic Cloud Before Entering

Physicists used weak measurements to probe how long photons spend in a rubidium atomic cloud as they travel straight through. They found a negative dwell time for those that pass, meaning the photons seem to arrive at the far side before they would have if they had spent time in the cloud, a result that matches the negative time inferred from arrival statistics. The effect is not an artifact of the measurement but a real, measurable quantum phenomenon explained by standard physics, highlighting that negative time in quantum interactions is possible and observable.

Exoplanet Smashes Record for Heaviest Element Detected in Atmosphere

Astronomers have detected the heaviest single element, samarium, in the atmosphere of an ultra-hot Jupiter exoplanet called MASCARA-4. The planet also has rubidium, which is the first time this element has been found in an exoplanet's atmosphere. The team used a spectrograph to measure starlight as the planet passed in front of its host star and hopes for follow-up observations to confirm the presence of these new chemical elements and refine their quantities in the atmosphere.

Exoplanet sets new record for heaviest elements detected in atmosphere.

Chinese astronomers used the ESPRESSO spectrograph to investigate the atmosphere of MASCARA-4b, an ultra-hot Jupiter exoplanet. They detected rubidium and samarium in an exoplanet's atmosphere for the first time, along with ions of titanium and barium. The study also confirmed previous detections of magnesium, calcium, chromium, and iron in the atmosphere of MASCARA-4b. The researchers encourage further atmospheric studies of exoplanets to find other rare elements.
