A spooky bat has been spotted flying over the European Southern Observatory's (ESO's) Paranal site in Chile, right in time ...

Scientists imaged the heart of the OJ 287 galaxy, uncovering a curved plasma jet around what appears to be two merging supermassive black holes. The structure reveals unimaginable energy levels and ...

The cluster can offer fresh insights into how stars of all sizes form and evolve. Star clusters are among the many objects observed by the Hubble Space Telescope. These gravitationally bound groups of ...

The galaxy our planet inhabits is called the Milky Way for the simple reason that, as seen from our world, its impossible-to-count collection of stars looks like a band of milky white light. In all ...

Peering into deep space, NASA's James Webb Space Telescope has helped astronomers find places to study gravitational lensing, an effect in which massive objects such as galaxies warp space-time itself ...

Analyses of its emissions using NASA’s Neil Gehrels Swift Observatory indicate that the interstellar comet probably has a very different structure than comets in the solar system. Hydroxyl compounds ...

The James Webb Space Telescope has uncovered a massive red supergiant star just before it exploded, finally solving a cosmic mystery. Hidden beneath layers of dust, the doomed star revealed itself ...

We all need some space sometimes—but it's harder to find than you might think. How far into our universe do we have to go to reach somewhere truly empty? Our first stop is the International Space ...

Astronomers say NASA’s James Webb Space Telescope may have spotted the universe’s first “dark stars,” primordial bodies of hydrogen and helium that bear almost no resemblance to the nuclear ...

A new analysis of our solar system’s interstellar interloper, 3I/ATLAS, reveals that it’s spewing huge amounts of water — and astronomers can’t immediately explain why. The object, which is widely ...
