A new image from NASA’s James Webb Space Telescope of a portion of the Helix Nebula highlights comet-like knots, fierce stellar winds, and layers of gas shed off by a dying star interacting with its surrounding environment. Webb’s image also shows the stark transition between the hottest gas to the coolest gas as the shell expands out from the central white dwarf.

NASA's James Webb Space Telescope just dropped the Exposed Cranium Nebula (PMR 1) — and yes, it looks exactly like a glowing human brain tucked inside a see-through skull. 5,000 light-years away in Vela constellation, this planetary nebula is the final exhale of an aging star shedding its outer layers.Side-by-side magic from Webb:

NIRCam (left): Sharp white "skull" bubble, fiery orange inner folds, that perfect dark central lane splitting it like brain hemispheres, and distant galaxies twinkling right through the shell.

MIRI (right): Bluish haze, thick creamy dust clouds, the dark lane half-hidden, and — get this — material erupting out the top like the star's still raging against the dying of the light.

This isn't just pretty; it's a snapshot of cosmic recycling. The elements forged in that star (carbon, oxygen, the stuff we're made of) are being scattered back into space to birth new worlds.

Cosmic Cliffs

#היסטוריה_בחלל

On December 25, 2021, one of the greatest moments in the world of modern astronomy occurred: NASA and its partners (the European Space Agency ESA and the Canadian CSA) successfully launched the James Webb Space Telescope (JWST), the scientific replacement of Hubble and Spitzer, but also a giant leap forward in humanity's observation capabilities.

So why is Webb considered a real revolution?

Seeing even further: Thanks to the giant 6.5-meter diameter vision and an advanced infrared device, Webb is able to observe the earliest universe and reach nearly the first moments of galactic formation.

Decoding the atmospheres of far-away planets: The telescope has already identified molecules in the atmospherics of worlds outside the solar system, including water, carbon dioxide, and methane.

Image quality never seen before: Webb delivers images with depth, sensitivity and unprecedented infrared quality never received from deep space. Thus, it allows us to see cosmic structures, nebulae, and star systems in a whole new way.

Since launching, James Webb continues to break records, answer ancient questions, and open new questions that expand the boundaries of human knowledge.
