New Hubble observations suggest comet 41P may have slowed down, stopped, and started spinning the opposite way after its close pass by the Sun in 2017. Comets may look calm in telescope images, glowing softly against the dark sky. But in reality, they...

NASA’s Hubble Space Telescope has captured a stunning new image of a distant galaxy, revealing fascinating details that offer a closer look at our universe. The Hubble Space Telescope has returned a striking new portrait of NGC 1827, an intermediate...

Astronomers discover a massive starless void in a distant galaxy, once mistaken for dust, may conceal a violent hidden phenomenon. Deep within the massive elliptical galaxy known as Abell 402‑BCG, researchers have uncovered a star‑free cavity spanning...

New observations suggest that active supermassive black holes play a key role in shaping star formation across their host galaxies. Active Galactic Nuclei May Foster Rather Than Hinder Star Formation A new investigation into nine nearby galaxies...

NASA unveils a multi‑sensory view of spiral galaxy Messier 94, merging X‑ray and visible light to spotlight its active star‑forming region. NASA has released a new visual‑audio composite of the nearby spiral galaxy Messier 94, showcasing the intricate...

Astronomers have uncovered a rare, decades-long flare from the Perseus Cluster’s central black hole, finally solving a mystery hidden in years of data. Astronomers tracking the behavior of a supermassive black hole at the heart of the Perseus Cluster...

A star shredded far from its galaxy’s center has revealed a massive black hole, challenging our understanding of how these giants roam through space. Astronomers have uncovered a massive black hole lurking 3,500 light-years away from the center of its...

A rare cosmic event hints that colliding black holes can produce light, but only under extreme conditions deep inside active galactic cores. Black holes are defined by absence. They swallow light, trap matter, and conceal their most violent processes...

A mysterious chemical discovery within a giant cloud near the Milky Way’s core is challenging current theories about how distant regions of space evolve. Astronomers have uncovered a massive, chemically diverse gas cloud near the galactic center that...

JWST observations of a mysterious red dot reveal that dense gas around a hidden engine, not ancient stars, creates the strongest Balmer break ever seen. Astronomers hunting the early Universe with JWST have repeatedly turned up compact, very red...

Chandra space telescope data has uncovered mysterious cosmic objects with a strange signature that defies current scientific classification. Data mined from the extensive archives of NASA’s Chandra X-ray Observatory has unveiled a previously...

New supercomputer simulations suggest dense gas and intense radiation may explain the origins of mysterious supermassive black holes in the early universe. Among the most perplexing targets identified by the James Webb Space Telescope (JWST) are the...

Astronomers have observed X-ray echoes from behind a supermassive black hole, providing direct confirmation of Einstein’s theory of general relativity. Astronomers have captured an extraordinary glimpse of light originating from behind a supermassive...

are so thick that the column density of electrons is roughly 10 to 100 times higher than what is found in a typical active galaxy. Shrinking the Giants Down to Size Once the team accounted for this scattering effect, they were able to “peel back” the...

JWST has discovered mysterious red object pairs in the early universe, suggesting galaxy interactions may drive the rapid growth of supermassive black holes. New analysis from the James Webb Space Telescope (JWST) has identified four candidate pairs of...

Brief flashes of millimeter-wave light seen by the South Pole Telescope reveal magnetic activity in compact white dwarf systems close to the Galactic center, showing that these small stars can release energy in unexpected ways. The center of the Milky...

After decades of development, a massive new space mission has launched, providing humanity with an unprecedented view into the universe’s hidden corners. The Sloan Digital Sky Survey (SDSS) has officially unveiled its 20th major data release, providing...

Astronomers have discovered a rare supernova that solves a 1,000-year-old mystery, revealing a third, distinct way that stars can explode. Astronomers have long sought to definitively observe an electron-capture supernova, a rare and specific death...

Astronomers have discovered a rare link between X-ray activity and delayed radio jets in a supermassive black hole located within the Perseus Cluster. A supermassive black hole residing at the heart of the galaxy NGC 1275 has offered astronomers a rare...

After 21 years in orbit, a legendary NASA observatory faces a fiery end, leaving behind a remarkable legacy of groundbreaking cosmic images. The Neil Gehrels Swift Observatory is entering the final chapter of its two-decade mission, yet the veteran...
