Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have found compelling evidence of a dark matter-deficient dwarf galaxy, FCC 224. This ultra-diffuse galaxy is located on the outskirts of the Fornax Cluster, approximately […]

Gas and dust ejected by a dying star at the heart of NGC 1514 came into complete focus thanks to mid-infrared data from the James Webb Space Telescope. Its rings, which are only detected in […]

A new study in Monthly Notices of the Royal Astronomical Society by researchers including István Szapudi of the University of Hawaiʻi at Mānoa Institute for Astronomy suggests the universe may rotate—just extremely slowly. The finding […]

NASA’s Lucy spacecraft is six days and less than 50 million miles (80 million km) away from its second close encounter with an asteroid; this time, the small main belt asteroid Donaldjohanson.This post was originally […]

In magnetic reconnection, adjacent magnetic field lines break and snap together to form new lines. This process converts magnetic energy to both thermal energy, or heat, and kinetic energy, or the acceleration of particles, creating […]

Using the radial velocity method, an international team of astronomers has discovered a new extrasolar planet orbiting a nearby star known as GI 410. The newfound alien world was classified as a sub-Neptune exoplanet with […]

Astronomers tallying up all the normal matter—stars, galaxies and gas—in the universe today have come up embarrassingly short of the total matter produced in the Big Bang 13.6 billion years ago. In fact, more than […]

An international team of researchers may have answered one of space science’s long-running questions—and it could change our understanding of how life began. Carbon-rich asteroids are abundant in space yet make up less than 5% […]

Through his research at Caltech, a local high school student revealed 1.5 million previously unknown objects in space, broadened the potential of a NASA mission, and published a single-author paper.This post was originally published on […]

Our new study of the nearby starburst galaxy Haro 11 has shown that strong X-ray-emitting superwinds may be a key mechanism enabling galaxies to leak ionizing radiation, which is believed to have played a major […]
