Neptune – The Real Blue Planet

Neptune is The Real Blue Planet, the Ice Giant of our Solar System residing far away from the Sun near the Kuiper Belt. The only one we cant see with the naked eye.

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

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...

This image shows the “moonrise” of the satellite as it emerges from behind asteroid Dinkinesh as seen by the Lucy Long-Range Reconnaissance Imager (L’LORRI), one of the most detailed images returned by NASA’s Lucy spacecraft during its flyby of the asteroid binary. This image was taken at 12:55 p.m. EDT (1655 UTC) Nov. 1, 2023, within a minute of closest approach, from a range of approximately 270 miles (430 km). From this perspective, the satellite is behind the primary asteroid. The image has been sharpened and processed to enhance contrast.

Nasa’s Lucy spacecraft discovers asteroid and its tiny moon during flyby

On Nov. 1, NASA’s Lucy spacecraft flew by not just its first asteroid, but its first two. The first images returned by Lucy reveal that the small main belt asteroid Dinkinesh is actually a binary pair...

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.

Video l Uranus – A Planet Tilted And It’s Emitting X-rays

When you look at images of planets in our solar system, they all seem to follow a certain design. The rocky ones are round with a few moons, while the gas giants and the ice giants have rings. But one...
