within roughly 20 parsecs (about 65 light‑years) of the Sun. In each case the faint remnant is eclipsed by a brighter red dwarf, whose glare masks the white dwarf in ordinary optical observations. The finding delivers the first direct evidence for a...

data from the Hubble Space Telescope. While UV imaging makes white dwarfs more conspicuous, energetic flares from the red dwarfs can mimic the same signal. By applying a set of bespoke calibration techniques, the team succeeded in disentangling the two...

Three unusual dwarf galaxies discovered by a student may unlock the mystery of how galactic encounters effectively shut down star formation. A fresh study led by a young researcher has identified three elusive dwarf galaxies that appear to defy the...

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...

Astronomers have discovered a giant planet that may have formed from the debris left behind by its host star’s dramatic death. Astronomers have identified a potential candidate for a rare “second-generation” planet, a world that appears to have...

New MEGATRON simulations reveal how ancient stellar explosions shaped the iron patterns found in today’s dwarf galaxies, linking the universe’s first stars. A new suite of sophisticated computer simulations, known as MEGATRON, is providing fresh...

Astronomers have discovered a star stripping material from a brown dwarf in a bizarre, record-breaking 87-minute orbit marked by a strange triangular signal. Astronomers have discovered a rare cosmic feeding cycle unfolding just 300 light-years from...

Astronomers discover a black hole wrapped in dense hydrogen 660 Myr after the Big Bang, shedding light on JWST’s red dots and rapid black‑hole growth. Observations with the James Webb Space Telescope have turned a faint point of light known as...

class, often found tucked between the massive, bright G dwarfs (like our Sun) and the diminutive, flare-prone M dwarfs (red dwarfs), is quickly becoming the darling of planetary science. The reason is rooted in cosmic time and stability. Our Sun, a...

Webb telescope observations have traced the most distant fast radio burst ever recorded to a strange, young dwarf galaxy 3 billion years after the Big Bang. Astronomers have traced a fleeting radio flash to a surprisingly humble origin. Utilizing the...

The Vera C. Rubin Observatory has discovered Aquarius IV, one of the faintest satellite galaxies ever observed orbiting our Milky Way. The Vera C. Rubin Observatory has officially logged its first major success, identifying an elusive satellite galaxy...

Violent eruptions on a distant red giant reveal how a stellar companion and magnetic forces combine to trigger extraordinary, powerful superflares. Astronomers have finally pinpointed the physical processes responsible for some of the most intense...

Astronomers have detected signs of a planet potentially formed from the debris of a dead star, offering a rare glimpse into a celestial rebirth. Astronomers have identified a potential “phoenix” world orbiting a white dwarf, a discovery that suggests...

Astronomers have discovered GJ 3090 b, an exoplanet orbiting its red dwarf star in the wrong direction, posing a mystery about its strange retrograde path. Astronomers have identified a planetary system that defies the conventional rules of stellar...

Earth. Located about 25 light‑years from Earth in the constellation Camelopardalis, the exoplanet GJ 3378b circles a dim red dwarf star. Researchers from the University of California, Irvine have determined that this planet, roughly twice Earth’s...

New calculations show Earth could avoid being swallowed by the Sun’s red‑giant phase, possibly moving to a wider orbit around the resulting white dwarf. In roughly five billion years the Sun will deplete the hydrogen at its core, swell into a red giant...

New simulations suggest the solar system’s giant planets could descend into orbital chaos far sooner after the Sun’s death than previously predicted. The long-term future of our solar system is likely to be far more volatile than previously imagined. A...

Scientists propose a bold plan to protect Earth from the Sun’s deadly expansion billions of years in the future. In roughly a billion years the Sun will exhaust its nuclear fuel and swell into a red giant, a transformation that could strip Earth of its...

Hubble’s view of a tiny galaxy provides the clearest evidence yet of how the early Universe cleared its primordial cosmic fog. A dwarf galaxy barely a hundredth the mass of the Milky Way has provided astronomers with one of the clearest looks yet at a...

excitement for further study. A new rocky super‑Earth, designated Gliese 3378b, has been confirmed orbiting a nearby red dwarf only 25 light‑years from Earth. The planet’s location inside its star’s habitable zone makes it a prime target for future...
