The Milky Way

Image: Horsehead Nebula (NASA Webb NIRCam): This image of the Horsehead Nebula, taken by NASA's James Webb Space Telescope, focuses on a portion of the "Horse's Mane" that is about 0.8 light-years across. It was taken using a camera Webb's NIRCam (near-infrared camera) The airy clouds at the bottom of the image are dominated by cold molecular hydrogen. Red streaks extending above the main nebula represent mostly atomic hydrogen gas in this region, known as the photodissociation region and from nearby masses creates a mostly neutral region of gas and dust between the fully ionized gas above and the cooler nebula below. As in many Webb images, distant galaxies are scattered in the background. This image consists of light at wavelengths of 1.4 and 2.5 microns (shown in blue), 3.0 and -3.23 µm (cyan), 3.35 µm (green), 4.3 µm (yellow), and 4.7 and 4.05 µm (red). Credit: NASA, ESA, CSA, K.

This image is from Gaia's third data release in 2022. The image above is from the new data release, and shows exactly how many new sources have been imaged at the center of the cluster. Only faint stars within Omega Centauri are marked in both images.

Gaia's Galactic Gold Mine: Star Clusters, Cosmic Lenses, Asteroids, and Unexpected Science

The European Space Agency's Gaia mission discovered over half a million new stars, tagged 150,000 asteroids, and identified 380 cosmic lenses. These discoveries advance our understanding of the universe, setting the stage for the expected release of Gaia DR4 data in 2025
Harvard astronomers claim that the Milky Way's warped shape is due to an unbalanced halo of dark matter. This claim supports theories of a previous galactic collision and provides insights into the nature of dark matter. Credit: Stefan Payne-Wardenaar; Magellanic Clouds: Robert Gendler/ESO

Hubble discovers a pulsating jet of stars in the Running Man Nebula that stretches over 18 trillion km in space

  • No comments
Generally, the flow of such a jet coming out of a young star will only be seen when it collides with material around it, and creates bright shock waves that disappear when they cool, so they are difficult to observe
Astronomers have discovered a huge ball-shaped hole in the Milky Way galaxy, its location is shown at right. A close-up view of the hole (left) shows the Perseus (in blue) and Taurus (bull) molecular clouds (in red). Although they appear to be inside the hole and touching, new XNUMXD images of the clouds show that they border the hole and there is a great distance between them.

Astronomers have discovered a huge ball-shaped hole in space

The "hole" spans about 150 parsecs -- close to 500 light years -- and is in the sky between the constellations Perseus and Taurus (bull). The research team, which operates at the Center for Astrophysics Harvard and the Smithsonian, believe the hole was created by supernovae that exploded about ten million years ago

A strange, repeating radio signal has been detected near the center of the Milky Way

  • No comments
It's not a fast radio burst, a pulsar, or a low-mass star that flares up every now and then. It is the radiating body in the radio field only for a few weeks, disappears at once, and returns again after a while. The researchers seek to understand what it is

On the map, which you can see above, the focal point from which the lines come out is at the point where the earth is located. To his right the older stars (red) around the center of the galaxy and to his left the younger stars (blue) in the outer parts of the disk. As the researchers in the group say, the Milky Way galaxy has grown outward over time.

Not just the entire universe: the Milky Way galaxy is expanding outward over time

An animation showing how the orbits of stars in the Milky Way may change. In the picture you see two pairs of stars (marked in blue and red). Each couple started their life on the same path and suddenly one of the stars in the couple changed its path. The star marked in red has completed its transition to its new orbit while the star marked in blue is still moving.
