The most energetic neutrino ever detected could be primordial

In the exotic world of particle physics, neutrinos may be the most mysterious members. They rarely interact with other matter, have almost no mass, and have no electrical charge. These characteristics make them extremely ...

Self-regulating process governs cosmic order inside star clusters

A team of astrophysicists from Nanjing University and University of Bonn have demonstrated that, rather than being random, the mass of new stars born inside a star cluster is actually governed by a defined process of self-regulation. ...

Scientists map hidden magnetism on the sun's far side

For observers on Earth, the sun appears as a bright, familiar disk—but what we see is only half the story. Like the moon, one half of the sun is permanently hidden from our direct view: the far side beyond the visible solar ...

Orbital dances unlock true masses of Orion's young stars

A star's mass determines its entire life story, from how it shines to how it dies. For young stars shrouded in dust, getting an accurate mass has long been difficult, but new radio measurements are beginning to change that. ...

Astronomers find an exo-Jupiter, and it seems to have clouds

A team of astronomers led by Elisabeth Matthews at the Max Planck Institute for Astronomy (MPIA) has made a discovery that highlights the limits of most current models of exoplanet atmospheres: water-ice clouds on a distant ...

Light-powered propulsion expands space exploration possibilities

Reaching the nearest star system, Alpha Centauri, would take hundreds of thousands of years using current rocket propulsion technology. Researchers in the J. Mike Walker '66 Department of Mechanical Engineering at Texas A&M ...

Webb redefines the dividing line between planets and stars

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that way.
