| Keeping the energy in the room Posted: 01 Jul 2022 01:33 PM PDT Researchers are developing precision optical sensors for telescopes and observatories. The team has now improved the spectra resolution of their superconducting sensor, a major step in their ultimate goal: analyzing the composition of exoplanets. |
| Capturing the onset of galaxy rotation in the early universe Posted: 01 Jul 2022 07:27 AM PDT After the Big Bang came the earliest galaxies. Due to the expansion of the universe, these galaxies are receding away from us. This causes their emissions to be redshifted (shifted towards longer wavelengths). By studying these redshifts, it is possible to characterize the 'motion' within the galaxies as well as their distance. In a new study, astronomers have now revealed a likely rotational motion of one such distant galaxy. |
| Floating in space might be fun, but study shows it's hard on earthly bodies Posted: 30 Jun 2022 10:48 AM PDT Bone loss happens in humans -- as we age, get injured, or any scenario where we can't move the body, we lose bone. Understanding what happens to astronauts and how they recover is incredibly rare. It lets us look at the processes happening in the body in such a short time frame. We would have to follow someone for decades on Earth to see the same amount of bone loss. |
