A Cosmic Surprise in the Depths of Space

Equipped with data from the DECaPS2 survey, Shapiro set out on a mission to locate supernova remnants—fossilized remnants of stars that had exploded eons ago. However, what he found was something entirely unexpected. The object he identified lacked the usual signatures of a supernova, such as central blast remnants or filament patterns.

The Echo of a Giant Black Hole

Utilizing the advanced capabilities of the Southern African Large Telescope, Shapiro was able to detect elevated levels of ionized sulfur and oxygen within the echoed region. These elements are indicative of gas being extremely heated by intense radiation, suggesting the existence of a supermassive black hole that was once highly active.

Potentially the Largest Light Echo Ever Observed

The sheer scale of this cosmic structure is breathtaking. Shapiro estimates it to stretch between 150,000 and 250,000 light-years across. For comparison, the Milky Way galaxy itself measures roughly 100,000 light-years in width. If verified, this could be the largest light echo ever captured by astronomers.

A Bright Future for an Aspiring Astronomer

Julian Shapiro’s passion for astrophysics is already propelling him into previously uncharted territories. While balancing his studies and college applications, he continues to present groundbreaking research at international conferences.

A Beacon of Hope for Young Astronomers

This incredible discovery signifies a transformative moment in astronomy, demonstrating that the field is open to everyone—not just seasoned scientists.
