Air leakage virtually unnoticeable aboard orbital outpost, cosmonauts say
TASS of Russia (12/1): Russian cosmonaut Sergey Kud-Sverchkov, one of two cosmonauts currently staffing the International Space Station (ISS), offered assurances Tuesday that a small air leak in the orbital outpost’s Russian segment is not a major concern. First noted in late 2019, the source was recently traced to a fracture with a scratch-like appearance in the Zvezda service module, which was launched in 2000. During a November spacewalk, Kud Sverchkov and cosmonaut Sergey Ryzhikov, the Station’s current commander, looked for evidence of external damage corresponding to the fracture but reported none. Editor’s note: TASS is a Russian state-owned news agency.

Missing dark matter & shadows from a black hole, Hubble continues to unlock cosmic mysteries
NASASpaceflight.com (11/30): Dark matter, a key ingredient for the formation and evolution of galaxies, is present in every galaxy observed. However, astrophysicists observed that galaxy NGC 1052-DF4 located 45 million light years from Earth was missing most of its dark matter. Using the Hubble Space Telescope, a team was able to observe that there was a tidal disruption “stripping” away the dark matter from NGC 1052-DF4.
