Artist’s impression of the gas-rich debris disk. Credit: NAOJ A Dutch-led team of astronomers has discovered that high-mass stars are formed differently from their smaller siblings. Whereas small stars are often surrounded by an orderly disk of dust and matter, the supply of matter to large stars is a chaotic […]

Could the “missing stars” be a completely new phenomenon? (Image credit: Tobias Roetsch) Stars don’t just vanish — or do they? For thousands of years, astronomers accepted the idea that the lights in the sky were fixed and unchanging. Even when it became clear that these lights were actually physical objects […]

Snapshot from the first full STARFORGE simulation. Nicknamed the “Anvil of Creation,” a giant molecular cloud with individual star formation and comprehensive feedback, including protostellar jets, radiation, stellar winds, and core-collapse supernovae.

A simulation of a 3-solar-mass star shows the central, convective core and the waves it generates in the rest of the star’s interior. Credit: Philipp Edelmann Astronomers commonly refer to massive stars as the chemical factories of the Universe. They generally end their lives in spectacular supernovae, events that forge […]

Unprecedented high-resolution map of the Orion Nebula Cluster showing newborn stars (orange squares), gravitationally collapsing gas cores (red circles), and non-collapsing gas cores (blue crosses). Credit: Takemura et al. A survey of star formation activity in the Orion Nebula Cluster found similar mass distributions for newborn stars and dense gas […]

Neutrinos are notoriously finicky particles.  Hundreds of trillions pass through a person’s body every second, yet they hardly seem to interact with anything (though they actually do a lot).  Even more hard to find are the “high energy” neutrinos that are believed to be formed as the outcome of some of the most violent […]

This is the compass image for VY Canis Majoris, showing the orientation and filters used. Credit: NASA, ESA, and R. Humphreys (University of Minnesota), and J. Olmsted (STScI) The red hypergiant VY Canis Majoris is enshrouded in huge clouds of dust Stars come in an extraordinary range of sizes. One […]
