Superluminous supernovas are the brightest stellar explosions in the universe. Astronomers may have found a mechanism that can trigger these events.

A rare gravitationally lensed supernova could help astronomers determine how fast the universe is expanding and shed light on dark energy. Astronomers may be closer to understanding one of the ...

Gold and platinum are found in space, created when two stars collide. Astrophysicists can even trace this process further back, to the merger of galaxies.

A quiet shift in the numbers behind the universe’s growth is pushing scientists toward a bold possibility. Two of the cosmos’ most elusive players, dark matter and neutrinos, may not be strangers ...

Scientists using a trio of some of the world’s most powerful observatories, the Hubble Space Telescope, ESA’s Euclid, and the Subaru Telescope, have pulled back the curtain on a ghost galaxy that is ...

Ultra-energetic gamma rays from distant cosmic explosions have reached Earth with no measurable energy-based delay, showing that light’s speed does not change even at extreme energies. By pushing this ...

A dazzling new Hubble image peels back the layers of the mysterious Egg Nebula, a rare and fleeting phase in a Sun-like star’s death just 1,000 light-years away. Hidden inside a dense cocoon of dust, ...

Space scientists have shown off an incredible image of a “space egg.” NASA said Tuesday the Hubble Space Telescope has revealed a dramatic interplay of light and shadow in what’s called the Egg Nebula ...

On July 2, 2025, the China-led Einstein Probe (EP) space telescope detected an exceptionally bright X-ray source whose brightness varied rapidly during a routine sky survey. Its unusual signal ...

On Tuesday, Feb. 17, 2026, a dramatic annular solar eclipse — popularly known as a “ring of fire” — will appear in the skies above remote parts of Antarctica home to two scientific research stations.
