Euclid captures the Milky Way’s crowded heart to weigh exoplanets

ESA's Euclid produced the largest, most detailed visible-light image of the Milky Way's central bulge, cataloging over 60 million stars in a nine-pointing mosaic captured in ~26 hours. The view enables microlensing studies to detect and measure exoplanets in our galaxy and will serve as a past/future time reference for the Roman telescope; the data already include hosts of known cold exoplanets such as OGLE-2005-BLG-390Lb and OGLE-2013-BLG-341Lb.

Webb and Hubble Uncover Terzan 5 as a Milky Way Bulge Fossil Fragment

Using Webb’s infrared observations and Hubble’s precise proper motions, researchers confirm Terzan 5 is not a globular cluster but a self-enriching relic in the Milky Way’s bulge, hosting up to four distinct star populations formed 12.5, 4.7, 3.8 and 2.5 billion years ago. The system likely survived as a remnant of a much more massive progenitor, offering clues to how galactic bulges form and evolve over cosmic time.

Unveiling the Hidden Secrets of the Universe's Zone of Avoidance

A new study has used infrared observations from the VISTA telescope to look for galaxies within the Zone of Avoidance, a region in the central part of the Milky Way filled with dust that blocks visible light. By comparing their candidates with data from the 2MASS Extended Source Catalogue, the team confirmed 75% of the galaxies in the region. This initial step opens the door to further study of thousands of galaxies hidden in the Zone of Avoidance, providing a better understanding of the universe.
