Astronomers Solve Betelgeuse’s 6-Year Dimming Mystery by Spotting Secret Companion Star
Astronomers have finally spotted Betelgeuse’s hidden companion star, ending a 1,000-year mystery about its six-year dimming cycle. Using Gemini North’s advanced imaging, researchers captured the first image of the elusive companion orbiting deep within Betelgeuse’s atmosphere. The discovery solves a stellar puzzle and offers new insight into ...

Hubble Uncovers Multi-Age Stars in Ancient Cluster, Reshaping Galaxy Origins
A stunning new image from NASA’s Hubble Space Telescope reveals that ancient star cluster NGC 1786—located 160,000 light-years away in the Large Magellanic Cloud—hosts stars of varying ages. Once believed to contain a single generation of stars, NGC 1786 now appears to preserve a more complex stellar history. This multi-age discovery suggests...

Young Exoplanet Spotted Shedding Atmosphere Under Stellar Radiation
NASA’s Chandra X-ray Observatory and Hubble Space Telescope have captured a dramatic cosmic event: a baby exoplanet, TOI 1227 b, is being stripped of its atmosphere by powerful X-rays from its host star. Only 8 million years old and orbiting a red dwarf, this Jupiter-sized planet is losing gas at a rate equal to Earth’s entire atmosphere every ...

Astronomers Capture Planet Birth Around Baby Sun Outside Solar System
Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a precious peek into the dawn of our own solar system.

Uranus Found Emitting Internal Heat, Reviving Hopes for Flagship NASA Mission
Astronomers have discovered that Uranus emits 12% more heat than it receives from sunlight, contradicting past data from Voyager 2. The internal warmth likely comes from leftover energy in the planet’s core, offering clues to its tilt and interior structure. This unexpected heat has intensified calls for a flagship NASA mission to Uranus. Scienti...

ESO Captures Clear Images of Interstellar Comet 3I/ATLAS Using VLT
The European Southern Observatory’s Very Large Telescope has captured the clearest images so far of comet 3I/ATLAS, an interstellar visitor first spotted on July 1, 2025. Identified by its hyperbolic orbit, the comet is only the third interstellar object recorded passing through our solar system. The VLT’s deep image and timelapse confirm it is...

New Interstellar Comet 3I/ATLAS Speeds Through Solar System
Astronomers have identified 3I/ATLAS as the third confirmed interstellar comet, racing through the solar system at 68 km/s. Discovered on July 1, it will pass near the sun in October. Skywatchers can view this rare object live online tonight, thanks to a live stream by the Virtual Telescope Project using observatories in Italy.

Webb Telescope Spots Possible Jellyfish Galaxy 12 Billion Light-Years Away
Astronomers using the James Webb Space Telescope have identified a possible jellyfish galaxy about 12 billion light-years away. Named COSMOS2020-635829, it shows tentacle-like streams of gas and stars trailing off one side—likely formed through ram pressure stripping in a dense cluster. If confirmed, it would be the most distant jellyfish galaxy ...

Astronomers Discover a Gigantic Supernova Remnant in the Large Magellanic Cloud
Veliki is a newly discovered, massive supernova remnant in the Large Magellanic Cloud, observed through a global collaboration using multiwavelength astronomy tools. Estimated to be 45,000 years old, Veliki showcases complex shell structures and highly unusual radio properties.

Astronomers Discover Baby Planets Taking Their First Steps in Nearby Stellar Nursery
Astronomers have detected early signs of planet formation in 27 young protoplanetary disks within the Ophiuchus star-forming region, just 460 light-years away. High-resolution imaging revealed spiral and ring patterns forming earlier than expected, suggesting stars and planets may grow together from infancy. The findings bridge a knowledge gap betw...

Most Distant Mini-Halo Discovered in Galaxy Cluster 10 Billion Light-Years Away
Astronomers have uncovered the most distant mini-halo ever detected, located around the galaxy cluster SpARCS1049, a staggering 10 billion light-years from Earth. Using the LOFAR radio telescope network, which spans eight European countries, researchers detected a faint, diffuse glow—evidence of a giant cloud of high-energy particles and magnetic...

Fast Radio Bursts Reveal Universe’s Missing Matter Hidden in Cosmic Intergalactic Fog
Astronomers have uncovered the universe’s missing baryonic matter using rapid radio bursts. The study, published in Nature Astronomy, shows that most ordinary matter lies between galaxies, hidden in faint intergalactic clouds. This breakthrough highlights FRBs as powerful tools to probe cosmic structures, paving the way for discoveries in large-s...

Archaeologists Discover Three Lost Maya Cities in Guatemala’s Jungle
Archaeologists from Slovakia and Guatemala have unearthed three previously unknown Maya cities in Guatemala’s Petén jungle. The sites—Los Abuelos, Petnal, and Cambrayal—feature ceremonial statues, pyramids, astronomical alignments, and advanced water engineering. Highlights include ancestral altars, a 108-foot pyramid, and a palace with a ro...
