At the center of our galaxy, where an enormous black hole blasts out energy as it chows down on interstellar detritus while neighboring stars burst to life and explode. astronomers have discovered two exhaust channels -- dubbed the 'galactic center chimneys' -- that appear to funnel matter and energy away from the cosmic fireworks.
VLA image shows the trail of a speeding pulsar pointing directly back at the center of the debris shell from the supernova that created it.
Astronomers have found a runaway pulsar hurtling through space at nearly 2.5 million miles an hour -- so fast it could travel the distance between Earth and the Moon in just 6 minutes.
A Southwest Research Institute-led team has discovered that the surface geology on asteroid Bennu is older than expected. Early observations of the near-Earth asteroid by NASA's OSIRIS-REx mission indicate a surface that is between 100 million and 1 billion years old.
Scientists have made observations of a molecular cloud that is collapsing to form two massive protostars that will eventually become a binary star system. The observations showed that already at this early stage, the cloud contains two objects, a massive 'primary' central star and another 'secondary' forming star, also of high mass.
Batteries power most of our devices, and even some cars. But researchers now report in ACS Applied Materials & Interfaces a step toward running electronic devices in homes and offices on the light coming from lamps scattered around the room. The team developed special light harvesters, like those used for solar power, optimized to produce energy from ambient indoor lighting.
Findings from an international team of scientists show that twisted magnetic fields can evolve in only so many ways, with the plasma inside them following a general rule.
Two recent studies report discoveries of dust rings in the inner solar system: a dust ring at Mercury's orbit, and a group of never-before-detected asteroids co-orbiting with Venus, supplying the dust in Venus' orbit.
According to a group of mathematics researchers, the probability in the following decade of the sun causing a storm strong enough to affect electrical and communication infrastructures around the globe 'only' reaches 1.9 percent maximum. Nevertheless, the event would produce severe consequences and governments should be prepared, researchers warn.
Astronomers have discovered a binary star system with the closest high-mass young stellar objects ever measured, providing a valuable 'laboratory' to test theories on high mass binary star formation.
