Scientists have detected "chirping" plasma waves at Mercury identical to those on Earth

Earth and Mercury share a cosmic melody: both planets emit similar "birdsong" electromagnetic waves, despite Mercury's weaker magnetic field. These chorus emissions, key in shaping space weather and radiation belts, advance our understanding of universal auroral processes and provide insights for future missions, including upcoming studies by BepiColombo Mio.
Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together while orbiting in an oval path, challenging long-standing assumptions about cosmic pair formation.
Most neutron star-black hole pairs are expected to adopt circular orbits long before merging, their orbits slowly rounded out by the constant emission of gravitational waves over millions of years.
Far from the warmth of any star, moons orbiting rogue gas giants might harbor oceans of liquid water—and potentially complex life—for billions of years.
Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun.
Look up on a clear night and you'll see the streaks of our modern satellite networks. What you don't see is the growing fallout for the atmosphere that keeps us alive.
A wave of satellite launches and reentries is changing the chemistry and physics of the middle and upper atmosphere. Studies warn of ozone depletion, stratospheric heating, and new metal aerosols from burning spacecraft.
