  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...

  Astronomers Successfully Weigh a Starless ‘Rogue Planet’ Drifting Through the Milky Way

  Astronomers have precisely measured the mass of a rogue planet wandering through the Milky Way using a rare gravitational microlensing event. By combining observations from ground-based telescopes across three continents with data from ESA’s Gaia spacecraft, researchers determined the planet’s distance and found it to be about the mass of Satur...

  Extreme Star Factory: ALMA Detects Galaxy Y1 Forming Stars 180 Times Faster Than the Milky Way

  Using ALMA’s ultra-sensitive Band 9 observations, astronomers identified galaxy Y1 as an extreme star-forming system in the early universe. Producing stars at 180 solar masses per year, Y1 reveals how intense, short-lived starbursts helped shape young galaxies and may have been more common than previously believed.

  James Webb Space Telescope Spots Rare Protostar Blasting Twin Jets Across Milky Way

  NASA’s James Webb Space Telescope has captured a rare protostar about ten times the Sun’s mass blasting twin jets nearly eight light-years long. The beams carve through the glowing Sharpless 2-284 nebula, offering astronomers a vivid glimpse into how massive stars form and shape their galactic environment.

  Astronomers Find a 200,000-Light-Year Black Hole Jet in the Early Universe

  Astronomers have identified the longest black hole jet observed in the early universe, stretching 200,000 light-years—twice the Milky Way’s width. Found in quasar J1601+3102, this jet was detected using the LOFAR telescope. Despite the black hole being 450 million times the Sun’s mass, it isn’t among the most massive. Scientists believe env...

  Supernova Remnant G278.94+1.35 is Closer to Earth, Claims New Study

  Astronomers discovered that the supernova remnant G278.94+1.35 is located just 3,300 light years away, much closer than previously believed. Initially thought to span over 500 light years, it is now estimated to measure around 189 by 182 light years. Named "Diprotodon" after Australia’s extinct giant marsupial, this structure remains in an expand...

  NASA’s Webb Telescope Reveals Firefly Sparkle, a Milky Way-Like Galaxy

  The James Webb Space Telescope has captured the Firefly Sparkle galaxy, existing 600 million years after the Big Bang. This rare discovery showcases a galaxy similar in mass to the Milky Way during its early years. Unprecedented details were revealed using gravitational lensing and infrared imaging, highlighting 10 distinct star clusters within Fir...

  A Nearby Supernova May End Dark Matter Search, Claims New Study

  A supernova within the Milky Way could revolutionise dark matter research by producing gamma rays from axions, elusive particles theorised to exist during a star's core collapse. Scientists at UC Berkeley are calling for gamma-ray telescopes to monitor the sky, ensuring readiness for the next nearby supernova. Such an event could confirm the axion'...

  Hubble Telescope Reveals Milky Way Blowing Gas off LMC Galaxy in Close Encounter

  NASA’s Hubble Space Telescope has captured an extraordinary phenomenon as the Milky Way galaxy exerts ram pressure on the Large Magellanic Cloud (LMC), stripping away most of its gas halo. The interaction, which occurs as LMC passes near the Milky Way, has led to the loss of significant mass from the dwarf galaxy. Despite this, LMC retains enough...

  James Webb Telescope Reveals Massive Westerlund 1 Super Star Cluster Hidden in Milky Way’s Dust

  The James Webb Space Telescope (JWST) has unveiled Westerlund 1, the Milky Way’s largest super star cluster, located 12,000 light-years away in the constellation Ara. This massive cluster, with stars up to 2,000 times larger than the Sun, has a total mass between 50,000 to 100,000 times that of the Sun. Previously hidden by cosmic dust, Westerlun...
