Missions, discoveries, and the science of exploring our solar system and beyond.
Astronomers found a galaxy with two generations of energy beams: one ancient and cold, the other just waking up. And a strange tai…
Fred Hoyle coined 'Big Bang' in 1949 to mock a rival theory. The universe didn't explode — space expanded. And the theory lacked…
A new Nature Astronomy study used 10 isotope systems simultaneously to show Earth built itself entirely from inner Solar System ma…
French physicist Jean-François Geneste proposes dropping a foundational axiom of geometry to build a universe model that unifies …
NewCluster tracks 10 chemical elements, cosmic dust, and galaxy motion inside a Virgo-sized cluster at 68-parsec resolution — fi…
For the first time ever, astronomers caught a comet reversing its own spin — driven by gas jets on its surface. Here's what come…
NASA's Hubble compared images taken 25 years apart and found the Crab Nebula's filaments still racing outward at 3.4 million mph �…
Galaxies in compact groups quench star formation faster than neighbors — but how far along they are depends on where the group s…
NASA's Parker Solar Probe completed its 27th solar flyby on March 11, 2026 — flying 3.8M miles from the Sun at 430,000 mph to un…
ASU researchers built a life-detection method based on atmospheric complexity — and Earth already scores higher than every other…
A nearly Earth-sized planet was found in archived K2 data from 2017 — orbiting a bright nearby star in or near the habitable zon…
A 0.9-second gamma-ray flash, a ghost galaxy buried in a cosmic tidal tail, and a chain of stellar collisions spanning 700 million…
NASA's James Webb Space Telescope turned two powerful instruments on spiral galaxy NGC 5134 — and captured how stars are born, g…
The cosmic microwave background shows the universe is geometrically flat — but flat doesn't mean infinite. Here's why the shape …
From the Canis Major Dwarf at 25,000 light-years to JADES-GS-z14-0 at the edge of observable time, a complete scientific guide to …
A 276,691-simulation study reveals alien rocks seized by our solar system's gravity survive far longer than expected — protected…
A first-of-its-kind joint analysis of NOvA and T2K data produces the strongest evidence yet that neutrinos and antineutrinos behav…
A Canadian Space Agency research framework reveals a striking truth — the medical systems needed to keep astronauts alive on Mar…
