NASA has begun a critical two-day wet dress rehearsal for the Artemis II mission at Kennedy Space Center, simulating launch procedures without engine ignition. The test involves loading the Space Launch System rocket with over 700,000 gallons of propellant and could pave the way for a crewed launch as early as February 8. This marks preparation for the first human trip beyond low Earth orbit since 1972.

Astronomers have identified a small companion star, named Siwarha, that is disturbing the atmosphere of the red supergiant Betelgeuse, explaining its unusual brightness changes. Using eight years of data from NASA's Hubble Space Telescope and ground observatories, researchers confirmed the companion's presence through a visible wake of dense gas. The discovery, announced at the American Astronomical Society meeting, sheds light on the evolution of massive stars.
