Astronomers have found evidence that one of the most massive white dwarfs known has an oxygen-neon core instead of the more common carbon-oxygen core. The find…

A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has captured a massive stream of gas—one trillion miles, or 0.2 light-years…

Astronomers may have just confirmed one of the quirkiest aspects of quantum mechanics: that seemingly empty space can alter the behavior of light. This phenome…

A SpaceX rocket that had been drifting in space for over a year crashed into the moon, creating a new crater that scientists will study to learn more about lun…

A supermassive black hole has been found lurking about 30,000 light-years from the center of its galaxy—the first dormant black hole detected so far from a gal…

A SpaceX rocket is about to hit the moon—these videos show what could happen Astronomers’ simulations predict what this lunar impact—and its aftermath—will lo…

Zodiacal dust in exoplanetary systems obscures signals crucial for detecting extraterrestrial life, complicating the search for biosignatures on distant planet…

Using the James Webb Space Telescope (JWST), astronomers obtained high-contrast coronagraphic images of the protoplanetary disk around the young, nearby star T…

Using spectral data from the Dark Energy Spectroscopic Instrument (DESI), astronomers have gained some of the clearest evidence yet that white dwarf stars are …

From how galaxies form to the beginnings of the universe, the images from the space telescope are giving cosmologists new data to explore—and theories to build…

A discovery in a solar system 73 light-years from Earth is challenging definitions and “blurring the lines between stars, planets, and moons.”
