Our Solar System Has a New Visitor: Interstellar Comet Could Be Nearly As Old as the Galaxy Itself

U-M astronomers are helping study a fast-moving, ancient, and massive comet that formed beyond our galaxy. A group of astronomers from around the world, including a doctoral student from the University of Michigan, were the first to report the discovery of the third confirmed interstellar object

“No One Had Any Idea This Existed” — Astronomers Discover Hidden River of Gas Flowing to the Milky Way’s Heart

Newly identified Midpoint cloud reveals rare insight into star formation and the movement of galactic material toward the center of the Milky Way. A group of astronomers from around the world has identified a vast cloud of gas and dust in an underexplored part of the Milky Way. This structure, cl

Early galaxies—or something else? Webb uncovers 300 unusually bright objects

In a new study, scientists at the University of Missouri looked deep into the universe and found something unexpected. Using infrared images taken from NASA’s powerful James Webb Space Telescope (JWST), they identified 300 objects that were brighter than they should be.

Study reveals mechanisms of rapidly driven plasma magnetic reconnection

A research team from the Yunnan Observatories of the Chinese Academy of Sciences has shed new light on the magnetic reconnection process driven by rapidly expanding plasma, using magnetohydrodynamic (MHD) numerical simulations. Their findings, published recently in Science China Physics, Mechanics & Astronomy, reveal previously unobserved fine structures and physical mechanisms underlying this fundamental phenomenon.

Magnetic reconnection—a process where break and rejoin, releasing massive energy—is critical to understanding explosive events in plasmas, from laboratory experiments to and space weather.

The team focused on how this process unfolds under rapid driving conditions, examining three distinct reconnection modes: flux pile-up, Sonnerup, and hybrid. These modes, they found, arise from variations in gas pressure and within the inflow region, where plasma is drawn into the reconnection site.

Scientists May Have Finally Found the Strange, Frozen Hideout of Missing Sulfur

Scientists may have found the hiding place of missing cosmic sulfur—in icy space dust, bound in crown-shaped and chain-like molecules that escape detection. For years, scientists studying the chemistry of the cosmos have searched for sulfur in space, only to discover that it appears to be far les

Hacking our way out of the universe

From Descartes to The Matrix, the idea that reality might be a simulation has long fascinated and terrified humanity. Elon Musk recently argued that the simulation hypothesis is most likely true. But if that’s the case, might there be a way to escape back to the real world? Join leading computer scientist Roman Yampolskiy as he argues that if we are living in a simulation, we can also hack our way out of it.
