  Kepler Data Reveals Earth-Size Exoplanet on the Edge of Its Star’s Habitable Zone

  Scientists studying Kepler telescope data have identified HD 137010 b, a possible Earth-sized planet orbiting a Sun-like star. While the planet follows a year-long orbit and may sit near the habitable zone, limited starlight could leave it colder than Mars. Future observations will determine whether this icy world truly exists.

  Astronomers Detect Rare Rogue Planet Drifting Alone 10,000 Light-Years from Earth

  Astronomers have confirmed a rare rogue planet, drifting without a star nearly 10,000 light-years away. Using gravitational microlensing, their distance and mass were measured, suggesting that free-floating planets may be abundant across the Milky Way. Upcoming telescopes, including NASA’s Roman Space Telescope and China’s Earth 2.0 mission, ar...

  Hubble Observations Turn Exoplanet Into Dust; Reveal Rare Double Asteroid Impact in Nearby System

  NASA’s Hubble Space Telescope has revealed that a vanished exoplanet near the star Fomalhaut was never a planet at all. Scientists discovered two rare, violent collisions between asteroid-sized bodies, producing glowing debris clouds that briefly mimicked planets. The findings offer a rare glimpse into how planetary systems evolve and how mislead...

  JWST Reveals Powerful Winds and Dense Atmosphere on Scorching Exoplanet TOI-561b

  Astronomers using NASA’s James Webb Space Telescope have found compelling evidence that TOI-561b, an ultra-hot rocky exoplanet orbiting its star every 11 hours, still retains a dense atmosphere. Temperatures measured on both its day and night sides are far lower than expected for a bare rock, implying powerful winds and efficient heat transport. ...

  Planet-Eating Stars Offer a Glimpse Into Earth’s Fate as the Sun Nears Its Final Stages

  Astronomers studying aging Sun-like stars have found strong evidence that stars consume their closest planets as they evolve. Using data from NASA’s TESS mission, researchers observed fewer planets around older stars, suggesting worlds are destroyed over time. The findings offer a realistic preview of Earth’s fate billions of years from now.

  NASA's Astronomers Reveal Red Giant Stars May Destroy Their Own Planets

  This extreme expansion poses a serious threat to nearby planets. For example, when the Sun becomes a red giant in about 5 billion years, it will likely swallow Mercury and Venus.

  Could a Planet Exist Without a Host Star? Astronomers Say Rogue Worlds May Roam Freely

  Astronomers have discovered that planets can survive without stars, drifting as rogue or hypervelocity worlds. Some are flung into space by black holes, while others are displaced by gas giants. On some of these rogue worlds, the idea goes, there might be oceans beneath icy crusts, where life, at least life at a microbe level, could exist.

  James Webb Space Telescope Spots Planet-Building Dust in the Butterfly Nebula

  The James Webb Space Telescope has unveiled stunning new details of the Butterfly Nebula, a planetary nebula 3,400 light-years away. Using its infrared vision, Webb detected crystalline silicates, large dust grains, and carbon-rich PAH molecules within the nebula’s dusty torus. These discoveries reveal how dying stars recycle minerals and organic...

  Astronomers Discover 3I/ATLAS, Largest Interstellar Comet Yet Detected

  Astronomers have discovered 3I/ATLAS, the third known interstellar comet to pass through our solar system. Detected by the ATLAS telescope in Chile, it’s racing inward at 150,000 mph and will swing closest to the Sun in October. Estimated to be 10–20 kilometers across, it is likely the largest interstellar object observed so far. Signs of comet...

  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...

  Quantum Tech Could Finally Let Astronomers Snap Direct Images of Earth-Like Exoplanets

  Astronomers are harnessing quantum mechanics to build a coronagraph that could directly image Earth-like exoplanets previously obscured by stellar glare. By sorting light waves at the photon level, the device bypasses traditional diffraction limits, revealing faint planetary signals. This breakthrough may redefine how scientists explore distant wor...

  Hubble Telescope Finds Unexpectedly Hot Accretion Disk in FU Orionis

  Hubble Space Telescope’s recent observations of FU Orionis have revealed surprising new details about the star’s accretion disk. The study found that the disk’s inner edge reaches temperatures as high as 16,000K, nearly three times hotter than the Sun’s surface. This discovery challenges existing models of stellar accretion, which had predi...
