Is the Universe Slowing Down? Astronomers Detect Signs of Fading Dark Energy
Astronomers from Yonsei University and DESI data analyses indicate dark energy, long believed constant, may be weakening. Corrected supernova results hint that cosmic acceleration is slowing—a possible “cosmic slowdown.” If true, this could help resolve the Hubble tension and redefine how the universe’s expansion and ultimate fate are under...

Hubble Observes Massive Stellar Eruption from EK Draconis, Hinting at Life’s Origins
Astronomers using the Hubble Space Telescope observed a huge solar storm from EK Draconis, a young Sun-like star. The eruption’s energy may trigger atmospheric chemistry, forming greenhouse gases and organic molecules. Such events could mirror early solar activity that helped spark life on ancient Earth and distant exoplanets.

Why October 29 Is Key To Solving The Mystery Of Comet 3I/ATLAS
NASA's Hubble, Webb, Parker Solar Probe, and other missions are tracking 3I/ATLAS to understand its true nature.

NASA Telescopes Capture First-Ever Companion Star Orbiting Massive Red Supergiant Betelgeuse
Astronomers have detected a small companion star orbiting the red supergiant Betelgeuse using Hubble and Chandra observations. Dubbed “Betelbuddy,” the discovery reveals an extreme binary system that challenges existing models of stellar evolution and may offer clues to Betelgeuse’s future.

White Dwarf Gobbles Up Nitrogen-Rich Ices of Pluto-Like World
Astronomers have observed a white dwarf, a highly compact stellar ember, that appears to have gobbled up an icy world akin to dwarf planet Pluto, a finding with implications regarding the likelihood of habitable planets beyond our solar system

Hubble Spots White Dwarf Devouring Icy Pluto-Like Planet 260 Light-Years Away
Using Hubble’s ultraviolet spectrograph, scientists detected carbon, nitrogen, sulphur, and abundant oxygen falling onto a white dwarf 260 light-years away, evidence of an icy planetesimal being torn apart. The find shows volatile worlds can persist into a star’s final stages, offering a preview of the Sun’s distant fate.

NASA Hubble Space Telescope Uncovers One of the Youngest Known Blue Straggler–White Dwarf Systems
Italian astronomers using the Hubble Space Telescope have discovered a white dwarf orbiting a blue straggler star in the globular cluster 47 Tucanae, located 15,300 light-years away. The rare system, among the youngest detected, sheds light on stellar mass transfer and offers vital clues to the evolution of binary stars in dense clusters.

NASA Captures Striking Image of Galaxy NGC 7456, 51 Million Light-Years Away
Hubble’s observing program has revealed new details of NGC 7456, a spiral galaxy in the constellation Grus, over 51 million light-years away. The image shows star-forming regions, dust clouds, and the galaxy’s patchy spiral arms.

Astronomers Discover Stellar Graveyard Filled With Black Hole and Neutron Star Collisions
Astronomers using LIGO-Virgo-KAGRA detected 128 collisions of black holes and neutron stars, including two rare mixed mergers that double previous records. These findings reveal new details of stellar evolution, refine Hubble constant estimates, and test Einstein’s relativity in extreme conditions. The cosmic “graveyard” offers fresh insight ...

NASA's Hubble Captures Interstellar Comet 3I/ATLAS Ahead of Close Mars Flyby
On October 3, 2025, interstellar comet 3I/ATLAS will pass just 30 million km from Mars — nine times closer than from Earth. ESA’s Mars Express and TGO, along with NASA and China’s orbiters, will attempt to image its coma, analyze gases, and study this rare visitor from beyond the solar system.

NASA’s James Webb Space Telescope Spots Rare Quintet of Galaxies From the Early Universe
Astronomers using JWST and Hubble have discovered JWST’s Quintet, a system of at least five merging galaxies just 800 million years after the Big Bang. This rare find shows how galaxies grew rapidly in the early universe and may explain how some became inactive so soon.

Who Is Megan McArthur, the First Woman to Pilot NASA's SpaceX Dragon?
NASA astronaut Megan McArthur, the first woman to pilot a SpaceX Dragon spacecraft, retires after 20 years. She logged 213 days in space, flew two missions, and was the last to handle the Hubble Telescope. Her contributions to ISS science and leadership roles shaped future lunar and Mars exploration, leaving a lasting mark on NASA’s mission

Hubble Discovers White Dwarf Merger Remnant with Unusual Carbon Signature
An international team of astronomers has discovered WD 0525+526, an unusual white dwarf about 128 light-years away, using NASA’s Hubble Space Telescope. Unlike typical white dwarfs, this star formed through a stellar merger and shows an unexpectedly high carbon content. With a mass of 1.2 Suns and a scorching surface temperature of 21,000 K, the ...

Earendel: JWST Suggests the Most Distant Star May Be a Star Cluster
Earendel, the farthest object ever seen, was first thought to be a single massive star from the early universe. New findings from JWST suggest it may instead be a star cluster, with many stars grouped together. Scientists used gravitational lensing to spot Earendel, which made its light appear thousands of times brighter.
