| Carbon dioxide cold traps on the moon are confirmed for the first time Posted: 15 Nov 2021 12:10 PM PST After decades of uncertainty, researchers have confirmed the existence of lunar carbon dioxide cold traps that could potentially contain solid carbon dioxide. The discovery will likely have a major influence in shaping future lunar missions and could impact the feasibility of a sustained robot or human presence on the moon. |
| Where does gold come from? New insights into element synthesis in the universe Posted: 15 Nov 2021 09:34 AM PST How are chemical elements produced in our Universe? Where do heavy elements like gold and uranium come from? Using computer simulations, a research team shows that the synthesis of heavy elements is typical for certain black holes with orbiting matter accumulations, so-called accretion disks. The predicted abundance of the formed elements provides insight into which heavy elements need to be studied in future laboratories to unravel the origin of heavy elements. |
| Hubble tension: Showing the cracks in Gaussian Processes Posted: 15 Nov 2021 09:34 AM PST A new analysis of the Hubble constant to show that the Gaussian Processes data reconstruction technique may not actually be independent of all cosmological models -- and that it may be time to question the validity of model independence itself. |
| Simulations provide clue to missing planets mystery Posted: 12 Nov 2021 07:05 AM PST New supercomputer simulations show that after creating a ring, a planet can move away and leave the ring behind. Not only does this bolster the planet theory for ring formation, the simulations show that a migrating planet can produce a variety of patterns matching those actually observed in disks. |
