    Raspberry in the sky: astronomers discover a new supernova remnant candidate
    RGB composite image where the total intensity map of Raspberry, observed by ASKAP at ν = 944 MHz, is in red and blue while WISE 12 µm infrared image is in green. To present the structure of Raspberry, different colormaps and adjusted contrast levels were used. A linear scale is applied to all images.

    Astronomers from the Western Sydney University in Australia and elsewhere report the detection of a new supernova remnant (SNR) candidate. The newfound SNR candidate, dubbed “Raspberry” due to its morphology, was identified in the near side of the Milky Way’s Scutum-Centaurus Arm. The findings were detailed in the Research Notes of the American Astronomical Society.

    Space Oddity: Uncovering the Origin of the Universe’s Rare Radio Circles

    January 9, 2024, Categories  Astronomy/Space

    Odd radio circles, like ORC 1 pictured above, are large enough to contain galaxies in their centers and reach hundreds of thousands of light years across. (cr: Jayanne English / University of Manitoba)

    Outflowing galactic winds from exploding stars may explain the enormous rings. Astronomers believe they may have found the origin of the universe’s giant odd radio circles: they are shells formed by outflowing galactic winds, possibly from massive exploding stars known as supernovae.

    t’s not every day astronomers say, “What is that?” After all, most observed astronomical phenomena are known: stars, planets, black holes and galaxies...

    Astronomers Detect New Pulsar Wind Nebula and its Associated Pulsar

    Astronomers detect new pulsar wind nebula and its associated pulsar
    Composite image of the Galactic plane region and Potoroo, with the red layer showing the ASKAP total intensity image at 1368 MHz, and the green and blue layers representing WISE infrared images at 12 µm and 22 µm respectively. Known Galactic SNRs are indicated by red circles (Green, 2019, 2022), while known Galactic HII regions are marked by green circles (Anderson et al., 2014). The box highlights the section of deep interest. The inset is the ASKAP zoomed-in image showing Potoroo where a red cross marks the position of the X-ray source, while a red dashed line is Potoroo’s axis of symmetry, which corresponds to the tail length studied in this paper.
