Tomorrow’s September #equinox signals the change of season, from summer to fall in the Northern Hemisphere and from winter to spring in the Southern Hemisphere. But why do Earth’s seasons change? 🤔 Read why at: buff.ly/tXTNtGi

This Hubble image shows interacting galaxies AM 1054-325. The clusters of stars born from the galaxy merger appear like a string of pearls. Formations like these were common in the early universe.

A pair of interacting galaxies. The galaxies have been distorted into a question mark shape. The stars and star clusters from the top galaxy that form the top curve of the question mark are white and yellow. The core of the top galaxy, inside the curve of the question mark, has a horizontal bar surrounded by a yellow haze of stars. The bottom galaxy, which forms the dot of the question mark, is irregular and blotchy, filled with white star clusters.

Groundbreaking new image! The EHT reveals the dynamic environment around black hole M87*.

The 2021 image shows a distinct shift in polarization patterns, tracing changes in magnetic fields near the event horizon.

What appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being eaten away by the blistering winds and ultraviolet light of nearby, massive, infant stars. What else did #NASAWebb find in Pismis 24? https://bit.ly/4mr3cmt

A blue and black sky filled with brilliant stars covers the upper two-thirds of the vertical image. The stars are different sizes and shades of white, beige, yellow, and pale orange. Across the bottom third of the scene is a craggy, mountain-like vista of dust and gas with spire-like peaks and deep, misty valleys. The peaks appear in varying shades of orange, yellow, and brown. Above their soaring spires is a wispy, ethereal white cloud that stretches horizontally across the scene. What looks like steam appears to rise from the mountaintops and joins this cloud. At the top right corner, a swath of orange and brown structure cuts diagonally across the sky.
