The LOFAR LoTSS-DR3 survey, an extensive effort utilizing a 2,000 km telescope aperture across 52 stations in Europe, has mapped 13.7 million cosmic sources, uncovering phenomena beyond optical sight and unlocking rare astrophysical mysteries. This mammoth task processed 18.6 petabytes of data with advanced algorithms correcting ionospheric distortions, revealing a comprehensive radio universe.
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.
