A rare cosmic event, in which a star reveals its inner structure as it explodes as a supernova, is reported in Nature. The observations offer insights into the evolution of stars and may confirm predictions about the structure of stars nearing the end of their lives. go.nature.com/4mp6I0q 🧪 🔭

We have images of a new interstellar visitor! ☄️ 👀

Comet 3I/ATLAS is only the third object ever spotted coming from beyond our Solar System.

In this timelapse, our VLT observes the comet move across the sky — just two days after its discovery!

This is one of the highest-resolution images ever to show "coronal rain"—cooler, ionised gas in the Sun's corona that falls back down, following curved magnetic field lines as it does so.

This image was taken in the hydrogen alpha spectral line; I inverted the image such that brighter = hotter.

🤩 The MIRI instrument on the NASA/ESA/CSA James Webb Space Telescope has captured a dying star’s display in unprecedented detail.

🔭 🧪

$What looks like a single large, bright star (but is two) shines with bright purple diffraction spikes at the center of a large, diffuse cylinder of gas and dust that is tipped to the right. At the center is a bright pink clumpy cloud that takes up about 25% of the view. There are two large rings seen at a roughly 60-degree angle that appear joined at top left and bottom right. The edges are denser, and form shallow V-shapes that go inward. The rings appear orange at top left and bottom right, and are blue at bottom and center right. There is diffuse orange material around the body. The black background of space is speckled with tiny stars and galaxies mostly in blues and yellows. Areas Webb did not observe are along the top edges, a thin vertical near the nebula at top left, and at the bottom left and right corners.$
