"Shiva and Shakti: Ancient Star Streams Unveil Milky Way's Earliest Building Blocks"

Scientists at the Max Planck Institute for Astronomy have identified two of the Milky Way’s earliest building blocks, named "Shakti" and "Shiva," which are remnants of galaxies that merged with an early version of the Milky Way 12-13 billion years ago. This discovery, based on data from the Gaia satellite and the Sloan Digital Sky Survey, sheds light on the galaxy's initial growth and could be the first additions to the "poor old heart" of the Milky Way, contributing to its evolution into a large galaxy.

"Unveiling Cosmic Origins: Observing Three Iron Rings Redefining Planet Formation"

Observations with the European Southern Observatory’s Very Large Telescope Interferometer found a three-ringed structure in the inner planet-forming disk of a young star, suggesting the formation of two Jupiter-mass planets in the gaps between the rings. The detailed analysis indicates the presence of abundant solid iron grains, resembling conditions during the formation of rocky planets in the early Solar System. This discovery offers insights into planet formation and the composition of planetary building blocks, potentially redefining our understanding of cosmic origins.
