Unravel the cosmic enigma of the "Champagne Cluster," where the mesmerizing interplay of galaxy clusters offers insights into dark matter. Two scenarios are depicted: "The Bounce Back," a 2-billion-year collision leading to a second union, and "The Recent Collision," a 400-million-year aftermath with clusters parting ways. Discovered on December 31, 2020, the event showcases the power of superheated gas and dark matter, outweighing galaxies within the clusters.
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.
