Scientists have discovered a star named S301 with the closest orbit to the Milky Way's central black hole, Sgr A*, using the GRAVITY instrument on the Very Large Telescope, which could provide insights into the black hole's spin.

Using a sample of 155,600 old Milky Way stars, researchers estimate the Universe's age as 13.73 Gyr, consistent with CMB-based ΛCDM predictions and casting doubt on new physics solutions to the Hubble tension.

NASA's July 2026 skywatching guide highlights a lunar-planetary alignment, Comet 10P/Tempel 2, views of the Milky Way, and Saturn's thin rings.

The Euclid space telescope captured the largest and most detailed visible-light image of the Milky Way's galactic bulge, showing over 60 million stars and aiding exoplanet discovery via gravitational microlensing.

NASA announces that the Nancy Grace Roman Space Telescope will launch soon to investigate potential life in the Milky Way, and invites the public to send their names on the mission.
