| 'Ears' for rover Perseverance's exploration of Mars Posted: 05 Apr 2022 09:39 AM PDT Scientists have built instruments to give humans eyes and a nose on Mars -- and now they are helping add ears as well. |
| Astrophysical plasma study benefits from new soft X-ray transition energies benchmark Posted: 05 Apr 2022 08:52 AM PDT The analysis of astrophysical plasmas is vital in the quest to learn about some of the Universe's most powerful and mysterious objects and events such as stellar coronae and winds, cataclysmic variables, X-ray binaries containing neutron stars and black holes, supernova remnants, or outflows in active galactic nuclei. The success of such research will lead to future astrophysical X-ray observatories enabling scientists to access techniques that are currently not available to X-ray astronomy. A key requirement for the accurate interpretation of high-resolution X-ray spectra is accurate knowledge of transition energies. |
| Scientists connect the dots between Galilean moon, auroral emissions on Jupiter Posted: 05 Apr 2022 07:28 AM PDT On November 8, 2020, NASA's Juno spacecraft flew through an intense beam of electrons traveling from Ganymede, Jupiter's largest moon, to its auroral footprint on the gas giant. Scientists used data from Juno's payload to study the particle population traveling along the magnetic field line connecting Ganymede to Jupiter while, at the same time, remotely sensing the associated auroral emissions to unveil the mysterious processes creating the shimmering lights. |
| 'Prenatal' protoplanet upends planet formation models Posted: 04 Apr 2022 09:04 AM PDT An international research team has discovered a new planet so young that it has yet to emerge from the womb of matter where it is forming. This is the youngest protoplanet discovered to date. It's location and the surrounding patterns of matter suggest that an alternative method of planet formation may be at work. This discovery could help to explain the histories and features of extrasolar planets seen around other stars. |
