Missions like the Hubble and James Webb space telescopes would have to patch together hundreds of small images to see these structures around nearby galaxies in full. Roman will do so in a single snapshot. Astronomers will use these observations to explore how galaxies grow and the nature of dark matter. |
| Posted: 15 Jun 2022 06:13 PM PDT Astronomers have imaged the debris disk of the nearby star HD 53143 at millimeter wavelengths for the first time, and it looks nothing like they expected. Based on early coronagraphic data, scientists expected ALMA to confirm the debris disk as a face-on ring peppered with clumps of dust. Instead, the observations took a surprise turn, revealing the most complicated and eccentric debris disk observed to date. |

| Astronomers discover a multiplanet system nearby Posted: 15 Jun 2022 06:12 PM PDT Astronomers discovered a multiplanet system just 33 light-years from Earth, making it one of the closest known multiplanet systems. The system likely hosts at least two terrestrial, Earth-sized planets. |
| Researchers model accelerator magnets' history using machine learning approach Posted: 15 Jun 2022 04:21 PM PDT After a long day of work, you might feel tired or exhilarated. Either way, you are affected by what happened to you in the past. Accelerator magnets are no different. What they went through -- or what went through them, like an electric current -- affects how they will perform in the future. Without understanding a magnet's past, researchers might need to fully reset them before starting a new experiment, a process that can take 10 or 15 minutes. Some accelerators have hundreds of magnets, and the process can quickly become time-consuming and costly. |
| Giving metal to microbes could reduce greenhouse gas Posted: 15 Jun 2022 04:21 PM PDT Collaborative research finds a lack of available metals may be responsible for more nitrous oxide than previously thought. |

| The potential of probabilistic computers Posted: 13 Jun 2022 04:34 PM PDT The rise of artificial intelligence (AI) and machine learning (ML) has created a crisis in computing and a significant need for more hardware that is both energy-efficient and scalable. A key step in both AI and ML is making decisions based on incomplete data, the best approach for which is to output a probability for each possible answer. Current classical computers are not able to do that in an energy-efficient way, a limitation that has led to a search for novel approaches to computing. Quantum computers, which operate on qubits, may help meet these challenges, but they are extremely sensitive to their surroundings, must be kept at extremely low temperatures and are still in the early stages of development. |
