Hubble Space Telescope | Zoom into the Triangulum Galaxy - Hubble Space Telescope #shorts @hubblespacetelescope | Uploaded October 2024 | Updated October 2024, 21 hours ago.
Fly across the local galactic neighborhood to the Triangulum galaxy (M33), a smaller spiral than our Milky Way galaxy.
Zoom in first on one of M33's bright regions of star birth, nebula NGC 604, glowing with hot ionized hydrogen gas. The remarkable ability of the Hubble Space Telescope to resolve millions of individual stars is on display in this pan across M33's dense star field.

This sequence uses visible (Hubble) and X-ray (Chandra) imagery to highlight different structures within the Whirlpool galaxy (Messier 51). As seen in visible light, the familiar whirlpool shape is traced out by glowing spiral arms. These arms are composed of billions of stars orbiting about the center of the galaxy over millions of years. The pink color is from hot hydrogen gas that permeates the galaxy and indicates sites of new star formation. Silhouetted in the bright arms are dark lanes of obscuring dust that blocks visible light. The stars farther away from the center orbit more slowly and fall behind, creating the signature spiral winding arm. A massive black hole lies at the galaxy’s center. The black hole can’t be seen directly, but its presence is hinted at by the dense star clusters at the center. A second smaller spiral galaxy can be seen in the upper-right portion of the image. The second image shows the X-ray view, highlighting the very hottest gas at millions of degrees Fahrenheit. The X-rays most closely match the visible pink hot gas in active star-forming regions and are particularly strong near the galactic centers of both galaxies. X-rays are also penetrating obscuring dust.

The Crab Nebula (Messier 1) is the remnant of a supernova that exploded in the year 1054 AD. This mysterious “new star,” as early skywatchers called it, was observed around the world and most notably recorded by Chinese astronomers. The supernova was triggered when the progenitor star abruptly collapsed onto its iron core, and rebounded to expel most of its layers of gas into a blast wave. This wave is seen as an optical and infrared set of filaments that continues to impact surrounding material. This material was expelled from the dying red giant progenitor star 20,000 years prior to the supernova. The ultra-dense remnant core, called a neutron star, is crushed to the size of a city. Spinning furiously, the neutron star sends out twin beams of radiation, like a lighthouse. A lot of this energy comes from the neutron star’s intense magnetic fields.
The initial radio image (from the Very Large Array Radio Telescope) shows the cool gas and dust blown out by the supernova winds. The infrared (Spitzer) image shows synchrotron radiation, an unusual form of light produced by electrons trapped in magnetic fields. The infrared image also shows hot gas. The visible-light image (Hubble) shows the detailed filamentary structure of the blast wave as it impacts the surrounding material. The ultraviolet image (XMM-Newton) shows hot, ionized gas. Finally, the X-ray emission (Chandra) from high-energy particles ejected from the pulsar shows the expanding nebula. The bipolar structure represents a powerful jet of material funneled along the neutron star’s spin axis.
