NASA's Chandra notices the galactic center is venting

Using NASA's Chandra X-ray Observatory, astronomers have located an exhaust vent attached to a "chimney" of hot gas blowing away from the center of the Milky Way galaxy. Their paper describing these results is published in ...

Physicists reach atomic-scale telegraphy with light

In the 1880s Heinrich Hertz discovered that a spark jumping between two pieces of metal emits a flash of light—rapidly oscillating electromagnetic waves—which can be picked up by an antenna. To honor his groundbreaking ...

NASA's CloudSat ends mission peering into the heart of clouds

CloudSat, a NASA mission that peered into hurricanes, tallied global snowfall rates, and achieved other weather and climate firsts, has ended its operations. Originally proposed as a 22-month mission, the spacecraft was recently ...

Astronomers propose a 50-meter submillimeter telescope

Some parts of the universe only reveal important details when observed in radio waves. That explains why we have ALMA, the Atacama Large Millimeter–submillimeter Array, a collection of 7-meter and 12-meter radio telescopes ...

Pushing the boundary on ultralow frequency gravitational waves

A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, the heaviest objects in ...
