Wispy hair-like filaments of pink-purple fill the middle of the image, curving left and right on either side of the centre. On the right, the filaments form a dramatic loop that seems to extend toward the viewer. At lower left are additional yellowish filaments. Two prominent, bright stars near the centre of the image show Webb’s eight-point diffraction spikes. Dozens of fainter stars are scattered across the image

Webb finds the smallest free-floating brown dwarf, which are also known as failed stars. Scientists imaged the centre of a cluster using Webb’s NIRCam and find three brown dwarfs.

Black Holes Consume Entropy

When you add information to a black hole, it gets larger. That in and of itself is not surprising, but black holes – and only black holes – grow in such a way that their surface areas, not their volum...

Happy Carl Sagan Day — The Voyagers and the Pale Blue Dot

Carl Sagan contributed immensely to how we perceive science, and to Voyagers 1&2, which are now in deep space & took the picture of the Pale Blue Dot.

This Hubble Space Telescope archival photo captures a curious linear feature that is so unusual it was first dismissed as an imaging artifact from Hubble's cameras. But follow-up spectroscopic observations reveal it is a 200,000-light-year-long chain of young blue stars. A supermassive black hole lies at the tip of the bridge at lower left. The black hole was ejected from the galaxy at upper right. It compressed gas in its wake to leave a long trail of young blue stars. Nothing like this has ever been seen before in the universe. This unusual event happened when the universe was approximately half its current age. Credits: NASA, ESA, Pieter van Dokkum (Yale); Image Processing: Joseph DePasquale (STScI)

Chinese Zhurong rover finds faint signs of water on Mars, which may have existed till only a few hundred thousand years ago.

Researchers used the Atacama Cosmology Telescope to create this new map of the dark matter. The orange regions show where there is more mass; purple where there is less or none. The typical features are hundreds of millions of light years across. The whitish band shows where contaminating light from dust in our Milky Way galaxy, measured by the Planck satellite, obscures a deeper view. The new map uses light from the cosmic microwave background (CMB) essentially as a backlight to silhouette all the matter between us and the Big Bang.
