Scientists discovered a massive hydrogen-producing hydrothermal system beneath the Pacific Ocean's seafloor, called the Kunlun hydrothermal field, which challenges traditional views on hydrogen generation and offers insights into deep-sea ecosystems, Earth's internal processes, and potential sustainable energy sources.
The James Webb Space Telescope has helped solve a long-standing mystery in astronomy by revealing that the mysterious hydrogen emissions observed around galaxies are likely the result of mergers between smaller, previously unobserved galaxies. These findings were made possible by Webb's powerful NIRCam instrument, which has provided unprecedented detail about the earliest regions of the universe and how they looked in much earlier times. The team's research, published in the journal Nature Astronomy, aims to further understand how hydrogen emission is ejected and reveal new clues to the evolution of galaxies.
Researchers have discovered that a round-bottomed wok can be repurposed into a functional radio telescope for capturing radio waves emitted by the heart of our galaxy. By adding a dipole antenna, balun, and plastic tubing to support the antenna at the focal point of the wok, along with a preamp and filter, the wok telescope was able to measure the recession velocity of neutral hydrogen with impressive accuracy. This DIY project offers an accessible and cost-effective way for enthusiasts to explore radio astronomy.
