    A team of astronomers says they have detected a never-before-heard radio signal that offers insights into the mystery of uncharted deep space. This signal is known as a Fast Radio Burst (FRB), a bright flash of radio light lasting for a few milliseconds and originating from beyond the Milky Way. Some FRBs repeat themselves, and a new study published in the Monthly Notices of the Royal Astronomical Society has shed new light. The study has detected a highly active repeating FRB signal behaving differently than anything previously detected. "This work is exciting because it provides both confirmation of known FRB...

    The latest image from NASA’s James Webb Space Telescope shows a portion of the dense center of our galaxy in unprecedented detail, including never-before-seen features astronomers have yet to explain. The star-forming region, named Sagittarius C (Sgr C), is about 300 light-years from the Milky Way’s central supermassive black hole, Sagittarius A*. Image: Sagittarius C (NIRCam) The NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope’s reveals a portion of the Milky Way’s dense core in a new light. An estimated 500,000 stars shine in this image of the Sagittarius C (Sgr C) region, along with some as-yet unidentified...

    Filaments In Space - MeerKAT data of the orientations of all the filaments, color-coded with position angles. (Farhad Yusef-Zadeh/Northwestern University) *********************************************************** An investigation into the mystery filaments hanging in space around the heart of the Milky Way has turned up an entirely new population of them, aligned along the galactic plane and pointing in the direction of the galactic center. The magnetized strands are likely the remnants of an outflow from the supermassive black hole Sagittarius A* interacting with the surrounding gas a few million years ago, says astrophysicist Farhad Yusef-Zadeh of Northwestern University. Although Sgr A* is pretty quiet...

    Explanation: This 180 degree panoramic night skyscape captures our Milky Way Galaxy as it arcs above the horizon on a winter's night in August. Near midnight, the galactic center is close to the zenith with the clear waters of Lake Traful, Neuquen, Argentina, South America, planet Earth below. Zodiacal light, dust reflected sunlight along the Solar System's ecliptic plane, is also visible in the region's very dark night sky. The faint band of light reaches up from the distant snowy peaks toward the galaxy's center. Follow the arc of the Milky Way to the left to find the southern hemisphere...
  • Mysterious ‘pulse’ detected in sky is leaving scientists dumbfounded

    University of Sydney lecturer Manisha Caleb explained in the report: “My colleagues and I (the MeerTRAP team) made the discovery when observing the Vela-X 1 region of the Milky Way about 1,300 light-years away from Earth, using the MeerKAT radio telescope in South Africa. “We spotted a strange-looking flash or “pulse” that lasted about 300 milliseconds.” The team scoured through old data from that region of space and found similar signals had been emitted before but had been missed by previous research. The strange pulses were said to be repeating every 76 seconds. The location of the strange object emitting...
  • Milky Way Galaxy Doomed: Collision with Andromeda Pending

    Explanation: Will our Milky Way Galaxy collide one day with its larger neighbor, the Andromeda Galaxy? Most likely, yes. Careful plotting of slight displacements of M31's stars relative to background galaxies on recent Hubble Space Telescope images indicate that the center of M31 could be on a direct collision course with the center of our home galaxy. Still, the errors in sideways velocity appear sufficiently large to admit a good chance that the central parts of the two galaxies will miss, slightly, but will become close enough for their outer halos to become gravitationally entangled. Once that happens, the two...

    In two weeks' time, the European Southern Observatory (ESO) is going to present the world with new information about our Milky Way. It's anyone's guess what the announcement will be, but based on what we know of their recent efforts, there's reason to get excited – the results being presented are from the Event Horizon Telescope (EHT) project, which was responsible for producing the first-ever image of a black hole in 2019. For years now the EHT project has been studying the heart of our home galaxy, the Milky Way, which is most likely home to a supermassive black hole...

    Explanation: The dream was to capture both the waterfall and the Milky Way together. Difficulties included finding a good camera location, artificially illuminating the waterfall and the surrounding valley effectively, capturing the entire scene with numerous foreground and background shots, worrying that fireflies would be too distracting, keeping the camera dry, and avoiding stepping on a poisonous snake. Behold the result -- captured after midnight in mid-July and digitally stitched into a wide-angle panorama. The waterfall is the picturesque Zhulian waterfall in the Luoxiao Mountains in eastern Hunan Province, China. The central band of our Milky Way Galaxy crosses the...

    A contingent of young stars and star-forming gas clouds is sticking out of one of the Milky Way's spiral arms like a splinter poking out from a plank of wood. Stretching some 3,000 light-years, this is the first major structure identified with an orientation so dramatically different than the arm's. Using NASA's Spitzer Space Telescope prior to its retirement in January 2020, they sought out newborn stars, nestled in the gas and dust clouds (called nebulae) where they form. Spitzer detects infrared light that can penetrate those clouds, while visible light (the kind human eyes can see) is blocked. Young...

    About 2,000 light-years away from Earth, there is a star catapulting toward the edge of the Milky Way. This particular star, known as LP 40−365, is one of a unique breed of fast-moving stars—remnant pieces of massive white dwarf stars—that have survived in chunks after a gigantic stellar explosion. “This star is moving so fast that it’s almost certainly leaving the galaxy…[it’s] moving almost two million miles an hour,” says JJ Hermes, Boston University College of Arts & Sciences assistant professor of astronomy. But why is this flying object speeding out of the Milky Way? Because it’s a piece of...

    Explanation: Globular star cluster Omega Centauri, also known as NGC 5139, is some 15,000 light-years away. The cluster is packed with about 10 million stars much older than the Sun within a volume about 150 light-years in diameter. It's the largest and brightest of 200 or so known globular clusters that roam the halo of our Milky Way galaxy. Though most star clusters consist of stars with the same age and composition, the enigmatic Omega Cen exhibits the presence of different stellar populations with a spread of ages and chemical abundances. In fact, Omega Cen may be the remnant core...

    For decades, astronomers debated whether a particular smudge was close-by and small, or distant and huge. A new X-ray map supports the massive option. hen Peter Predehl, an astrophysicist at the Max Planck Institute for Extraterrestrial Physics in Germany, first laid eyes on the new map of the universe’s hottest objects, he immediately recognized the aftermath of a galactic catastrophe. A bright yellow cloud billowed tens of thousands of light-years upward from the Milky Way’s flat disk, with a fainter twin reflected below. The structure was so obvious that it barely seemed necessary to describe it in writing. But “Nature...

    Most of the alien civilizations that ever dotted our galaxy have probably killed themselves off already. That's the takeaway of a new study, published Dec. 14 to the arXiv database, which used modern astronomy and statistical modeling to map the emergence and death of intelligent life in time and space across the Milky Way.
