    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

    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...

    Slingshotting Around the Sun would make a Spacecraft the Fastest Ever

    NASA is very interested in developing a propulsion method to allow spacecraft to go faster. We’ve reported several times on different ideas to support that goal, and most of the more successful have utilized the sun’s gravity well, typically by slingshotting around it, as is commonly done with Jupiter currently.

    But, there are still significant hurdles when doing so, not the least of which is the energy radiating from the sun simply vaporizing anything that gets close enough to utilize a gravity assist...

    Supermassive Black Hole appears to Grow Like a Baby Star

    Galactic whirlwind
    Artist’s impression: A spiralling wind helps the supermassive black hole in galaxy ESO320-G030 to grow, assisted by magnetic fields. In this illustration, the core of the galaxy is dominated by a rotating wind of dense gas leading outwards from the (hidden) supermassive black hole at the galaxy’s very centre. The motions of the gas, traced by light from molecules of hydrogen cyanide have been measured with the Alma telescope. Image credit: M. D. Gorski/Aaron M.

    Supermassive black holes pose unanswered questions for astronomers around the world, not least “How do they grow so big?” Now, an international team of astronomers, including researchers from Chalmers University...
