Astronomers Image Stellar Eruptions, Find Rotating Cosmic Filament Shaping Galaxies

• Astronomers captured images of two novae shortly after eruption using the CHARA Array, revealing complex expanding material and ejections around the dying stars.
• Cosmic filaments, which channel matter to young galaxies, were observed to have notably aligned galactic rotation, with entire filaments appearing to rotate collectively.
• This collective rotation challenges previous assumptions about random galactic alignment and provides insight into how galaxies gain momentum, gather fuel, and grow.
• The research, published in Monthly Notices of the Royal Astronomical Society, utilized MeerKAT radio data and optical surveys to deepen understanding of stellar lives and galaxy evolution.

Why It Matters: It clarifies stellar deaths and galaxy formation, impacting cosmic evolution theories.
