Physicists at Technical University of Munich discover potential existence of tetra-neutron, a bound state of four neutrons, which could significantly alter our understanding of nuclear forces. The experiment's results suggest a half-life of 450 seconds and stability comparable to the neutron.
A team of astrophysicists led by Boston University's Merav Opher has made a groundbreaking discovery about the heliosphere, the bubble surrounding our solar system. Their research suggests that neutral hydrogen particles play a crucial role in shaping the heliosphere's structure and stability.
GSI/FAIR researchers aim to study properties of hypernuclei, which could shed light on neutron star phenomena. The WASA detector will help determine binding energy and lifetimes with higher detection efficiency.
A Caltech researcher has found that the Schrödinger Equation governs the evolution of massive astrophysical disks. The equation, typically used for subatomic systems, describes how warps and distortions emerge in these disks over millions of years. This surprising discovery could provide new insights into complex astronomical phenomena.
The Super-Kamiokande detector is equipped with a new computer system to monitor neutrinos from nearby supernovae in real-time. This allows scientists to assess the significance of signals within minutes and issue early warnings to research centers worldwide.
A systematic review presents the state of the art in investigating the existence of grains in space-time, which could lead to violations of special relativity. Physicists have devised methods to test these deviations using high-energy astrophysics phenomena.
A University of Colorado Boulder research team has confirmed a theory about charged dust in space, explaining how it affects spacecraft and astronauts. The study used an experiment to levitate particles with positive charge above the moon's surface.
A team of scientists identified Io as the dominant source of the Jovian dust streams, which are high-rate bursts of submicron-sized particles. The particles' motion is strongly influenced by Jupiter's magnetic field, providing a unique signature that could only be present if Io were the dominant source.
Deep Space 1, a miniaturized space probe powered by solar-electric propulsion, will navigate through space and analyze charged particles and magnetic fields surrounding an asteroid and two comets. The mission, led by CU-Boulder Professor Fran Bagenal, tests innovative technologies and aims to explore the outer solar system.
The CU-Boulder payload, dubbed COLLIDE, analyzes the gentle collisions of dust particles in space to understand the dynamics of larger particles. Four different impact speeds and two different depths of dust will be tested to shed light on the mysterious disappearance of dust from planetary ring particles.
A team at University of Colorado at Boulder has found a faint, doughnut-shaped ring of interplanetary and interstellar dust orbiting Jupiter. The ring is much larger and more sparse than previously detected rings, and most particles in it move in the opposite direction to Jupiter's rotation.
A new study led by a University of Colorado astrophysicist suggests that dust grains dominating Jupiter's peculiar ring may have lifetimes of just hours or days. The study indicates the swelling of the inner ring is caused by positive electrical charges on the dust grains resulting from solar radiation.
