A new computer simulation reveals how icy particles drift and clump together to form giant-planet cores before their surrounding gas disks disappear. For decades, the formation of gas giants like Jupiter and Saturn has challenged planetary scientists....

NASA’s new wide-field telescope is set to survey the cosmos, aiming to uncover groundbreaking astronomical discoveries that no one expects. NASA is gearing up for the launch of the Nancy Grace Roman Space Telescope, an ambitious observatory engineered...

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...

their origins were often hindered by the sheer brightness of the central emission, which effectively masked any potential host galaxy structures nearby. Stacking approach reveals extended emission in LRDs at F444W. Credit: Xuheng Ding et al, Nature...

expansion rate—can be derived from gravitational‑wave distances, either directly from the signal or by identifying the host galaxy. “The rate of this expansion is described by a value called the Hubble constant. Gravitational waves allow us to measure...

Scientists used a novel technique on NASA data to uncover a previously hidden planet, revealing a world once thought out of reach. NASA’s TESS (Transiting Exoplanet Survey Satellite) has identified a distant exoplanet hidden in its archive by...

NASA’s upcoming Habitable Worlds Observatory aims to revolutionize the hunt for Earth‑like planets and extraterrestrial life beyond our solar system. NASA is outlining concepts for the Habitable Worlds Observatory, a cutting‑edge telescope intended to...

Using next-generation telescope data, astronomers have uncovered a complex new mystery behind two distant cosmic sources that previously puzzled researchers. New data from the James Webb Space Telescope (JWST) has forced a significant reclassification...

South Africa’s MeerKAT telescope has detected the first radio signals from an exoplanet, offering a groundbreaking method to study alien magnetic fields. Astronomers have achieved a long-awaited milestone in planetary science by successfully isolating...

on the mass and spin of the original black holes, this recoil can potentially send the object hurtling through its host galaxy. Theoretical work led by researchers including Peter Raffai, Zoltán Haiman, and Zsolt Frei in 2015 predicted that if a...

the team found significant improvements in specific cosmological parameters. The uncertainty regarding the mean host galaxy contribution shrank by a factor of 4.1, dropping to just 7.3 cubic centimeters per second of dispersion measure offset....

NASA’s Roman Space Telescope may spot distant black holes The Nancy Grace Roman Space Telescope is poised to revolutionize the hunt for distant black holes by capturing thousands of transient stellar disruptions across the cosmos. A study released...

The resulting NASA’s Webb observations not only visualized the explosion but also provided the first-ever detection of a host galaxy at such an extreme distance. “Webb provided the rapid and sensitive follow-up we needed,” remarked Benjamin Schneider, a...

NASA researchers are developing an innovative starshade concept designed to block blinding starlight and finally reveal hidden, Earth-like exoplanets. Cutting Through Stellar Glare: The Quest to Image Earth-Like Worlds Astronomers have long faced a...

The James Webb Space Telescope has uncovered evidence of rapid planet formation around young stars, though the full implications remain a cosmic mystery. New findings from the James Webb Space Telescope (JWST) have provided a clearer picture of how...

Astronomers have detected radio waves from an exoplanet, marking the first time a magnetic field has been measured on a world beyond our solar system. Astronomers have achieved a milestone in planetary science by capturing the first direct radio...

Astronomers have detected a potential helium signal from exoplanet LHS 1140b, offering a rare look at the atmosphere of a potentially habitable world. Astronomers may have identified traces of helium escaping from the atmosphere of LHS 1140b, a...

Astronomers have discovered unexpected molecules around 11 young stars, revealing new chemical insights into how planetary systems form and evolve. Astronomers peering into the cradles of distant solar systems have uncovered a surprising chemical...

conventional expectations. Following the initial trigger, the optical afterglow intensified until it overshadowed the host galaxy itself. By the time researchers measured the event across multiple wavelengths, they found that its X-ray and optical...

An unprecedented 8-billion-pixel radio image has mapped nearly 63,000 cosmic sources, revealing distant galaxies and black hole jets in stunning detail. Astronomers have unveiled a remarkably high-resolution map of the low-frequency radio sky,...
