  New Interstellar Object 3I/ATLAS Could Reveal Secrets of Distant Worlds

  Astronomers have confirmed the arrival of 3I/ATLAS, only the third interstellar object ever spotted in our solar system. First seen on July 1, 2025, by the ATLAS survey team in Chile, it was quickly identified by its unusual hyperbolic orbit and comet-like tail. Larger and brighter than either 1I/ʻOumuamua or 2I/Borisov, 3I/ATLAS is estimated to b...

  Scientists Say Dark Matter Could Turn Failed Stars Into ‘Dark Dwarfs’

  Astronomers suggest that brown dwarfs—dim, failed stars—could transform into “dark dwarfs” by capturing dark matter in their cores. When dark matter particles annihilate, they release heat, potentially lighting up these stars. Physicist Jeremy Sakstein and researchers like Jillian Paulin and Rebecca Leane support this idea, which could help...

  NASA's New Horizons Proves Deep-Space Navigation via Stellar Parallax

  NASA’s New Horizons spacecraft accomplished a world-first by performing a deep-space stellar navigation test using stellar parallax. On April 23, 2020, while 438 million miles from Earth, it imaged nearby stars Proxima Centauri and Wolf 359. From the spacecraft’s distant viewpoint, the stars appeared slightly shifted compared to Earth-based obs...

  Astronomers Discover "Water-Rich Super-Earth" Twice As Big As Our Planet

  Scientists have discovered a new "super-Earth" that is located about 154 light-years away and is nearly twice as big and four times as massive as our planet.

  NASA Astronaut Captures Stunning 'Sprite' Light Show Above Earth's Atmosphere

  Sprites are a type of TLE, which create brilliant flashes of light high above powerful thunderstorms and are difficult to observe from the ground.

  Dead NASA Satellite Relay 2 May Have Caused Mysterious 2024 Radio Burst

  In June 2024, a mysterious 30-nanosecond radio burst baffled scientists — until they traced it back to a surprising source: Relay 2, a NASA satellite offline since 1967. Researchers believe the signal could have been triggered either by a micrometeorite impact or an electrostatic discharge. The discovery, detailed in a new preprint study, highlig...

  Scientists Spotted the Largest Comet Lying in the Solar System’s Outskirts with Outbursting Gases

  NASA confirms comet C/2014 UN271, the largest known from the Oort Cloud, is chemically active. Detected by ALMA from far beyond Neptune, the comet’s carbon monoxide jets offer rare insights into icy body chemistry and early solar system conditions.

  NASA Study Reveals Correlation Between Earth’s Magnetic Field and Atmospheric Oxygen

  According to NASA, changes in Earth’s magnetic field 540 million years ago corresponded with atmospheric oxygen shifts. This finding suggests that Earth’s deep interior may impact surface habitability. Scientists plan further research to trace these connections and their role in life’s origin.

  "Mushroom" On Mars: Is This A Sign Of Life On Red Planet?

  While there's currently no definitive evidence of life on the Red Planet, scientists continue to explore the possibility.

  New Habitability Model Helps Identify Which Alien Planets Might Be Able to Host Life

  A NASA-developed model now enables scientists to estimate the likelihood of life on distant planets or moons using limited and uncertain remote-sensing data. By comparing habitat conditions with known lifeforms or hypothetical organisms, the framework offers a probabilistic tool to assess alien environments and improve telescope targeting in the on...

  NASA Chandra Spots Distant X-Ray Jet; Telescope Faces Major Budget Cuts

  NASA’s Chandra X-ray Observatory has detected a massive X-ray jet from quasar J1610+1811, 11.6 billion light-years away. The jet travels at nearly the speed of light, illuminating black hole behavior during the universe’s early era. However, Chandra now faces potential defunding under NASA’s proposed budget. Astronomers warn that cutting Chan...

  Hubble Finds Cosmic Dust Coating Uranus’ Moons, Not Radiation Scars

  New Hubble Space Telescope observations have upended decades of expectations about Uranus’ moons. Scientists once thought the planet’s magnetic field darkened their backsides with radiation, but the latest data shows Titania and Oberon are collecting space dust on their leading sides instead. This “cosmic bug splatter” effect suggests dust ...

  Parker Solar Probe Witnesses Unprecedented Sunward Plasma Jet Driven by Magnetic Reconnection

  NASA's Parker Solar Probe has made a groundbreaking discovery, observing an unprecedented plasma explosion in the Sun's corona. This rare event produced a sunward jet of particles, with protons accelerated to nearly 1,000 times the expected energy. Scientists traced this phenomenon back to a magnetic reconnection site, where twisted solar magnetic ...
