    Tiny Bright Objects discovered at Dawn of Universe baffle scientists

    Researchers investigated three mysterious objects in the early universe. Shown here are their color images, composited from three NIRCam filter bands onboard the James Webb Space Telescope. They are remarkably compact at red wavelengths (earning them the term “little red dots”) with some evidence for spatial structure at blue wavelengths. Credit: Provided by researchers / Penn State. All Rights Reserved.

    A recent discovery by NASA’s James Webb Space Telescope (JWST) confirmed that luminous, very red objects previously detected in the early universe upend conventional thinking about the origins and evolution of galaxies and their supermassive black holes.

    An international team, led by Penn State researchers, using the NIRSpec instrument aboard JWST as part of the RUBIES survey...

    Pillars of Creation star in New Visualization from NASA’s Hubble and Webb Telescopes

    June 28, 2024, Categories  Astronomy/Space

    A mosaic of visible-light (Hubble) and infrared-light (Webb) views of the same frame from the Pillars of Creation visualization. The visualization sequence fades back and forth between these two models as the camera flies past and amongst the pillars. These contrasting views illustrate how observations from the two telescopes complement each other.

    Made famous in 1995 by NASA’s Hubble Space Telescope, the Pillars of Creation in the heart of the Eagle Nebula have captured imaginations worldwide with their arresting, ethereal beauty.

    Now, NASA has released a new 3D visualization of these towering celestial structures using dat...

    First of its kind Detection made in Striking New Webb Image

    June 27, 2024, Categories  Astronomy/Space

    A rectangular image with black vertical rectangles at the bottle left and top right to indicate missing data. A young star-forming region is filled with wispy orange, red, and blue layers of gas and dust. The upper left corner of the image is filled with mostly orange dust, and within that orange dust, there are several small red plumes of gas that extend from the top left to the bottom right, at the same angle. The center of the image is filled with mostly blue gas. At the center, there is one particularly bright star, that has an hourglass shadow above and below it. To the right of that is what looks a vertical eye-shaped crevice with a bright star at the center. The gas to the right of the crevice is a darker orange. Small points of light are sprinkled across the field, brightest sources in the field have extensive eight-pointed diffraction spikes that are characteristic of the Webb Telescope.
    In this image of the Serpens Nebula from NASA’s James Webb Space Telescope, astronomers found a grouping of aligned protostellar outflows within one small region (the top left corner). Serpens is a reflection nebula, which means it’s a cloud of gas and dust that does not create its own light, but instead shines by reflecting the light from stars close to or within the nebula.

    For the first time, a phenomenon astronomers have long hoped to directly image has been captured by NASA’s James Webb Space Telescope’s Near-Infrared Camera (NIRCam)...

    A Hidden Treasure in the Milky Way – Astronomers uncover Ultrabright X-ray Source

    June 26, 2024, Categories  Astronomy/Space

    Illustration: Alexander Mushtukov: A view towards the black hole in an X-ray binary and the X-rays we see that are reflected from the inner surface of the powerful outflow surrounding the hole. 

    Astronomers uncovered that a well-known X-ray binary, whose exact nature has been a mystery to scientists until now, is actually a hidden ultraluminous X-ray source. X-ray binaries are intriguing systems consisting of two celestial bodies: a normal star and a compact, dead object such as a black hole or a neutron star that sucks material from its stellar companion. A few hundred such sources have been identified thus far in our Galaxy...
