Orion’s Erupting Star System Reveals Its Secrets
FUor stars flare suddenly, erupting in brightness, before dimming again many years later. It is now understood that this brightening is due to the stars taking in energy from their surroundings via gravitational accretion, the main force that shapes stars and planets. However, how and why this happens remained a mystery—until now, thanks to astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA).

A groundbreaking investigation into Compact Symmetric Objects (CSOs), a peculiar class of galaxies, has revealed new insights into their spectacular but short-lived existence
Compact Symmetric Objects (CSOs) have long puzzled astronomers with their unique characteristics. These active galaxies harbor supermassive black holes that emit powerful jets traveling at near-light speeds in opposite directions. However, unlike their counterparts in other galaxies, these jets remain compact, not extending out to great distances as expected. For decades, scientists presumed that CSOs were youthful entities, with their jets destined to expand over time.
New findings, published in three papers in The Astrophysical Journal, challenge this notion. The Caltech-led team, spearheaded by Anthony (Tony) Readhead, Robinson Professor of Astronomy, Emeritus, discovered that CSOs have relatively short lifespans. Through an exhaustive review of literature and observations, the team identified over 3,000 CSO candidates, confirming 64 as authentic CSOs and recognizing 15 new candidates. These objects were previously observed by the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO)’s Very Long Baseline Array (VLBA), renowned for its unparalleled resolution.
The studies, funded by NSF, NASA, Caltech, and the Max Planck Institute for Radio Astronomy in Bonn, Germany, mark a significant step forward in understanding the dynamic processes shaping our universe. Read the full Caltech release and view NRAO’s scientific visualization animation.
