Dwarf planet Pluto in False Colour

How Pluto Got its Heart

How Pluto Got its Heart according to a new study. It happened due to a giant and slow oblique-angle impact on the Dwarf Planet.

Podcast Episode 79 l Neptune – The Real Blue Planet

Podcast Episode 79 is all about Neptune, which is The Real Blue Planet in our Solar System, as well as being an ice-giant orbiting the Sun from far away.

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.

Image shows artists impression of Mars core. Analysis of Martian seismic data recorded by the InSight mission have revealed that Mars’s liquid iron core is surrounded by a150-​km thick molten silicate layer, as a consequence of which its core is smaller and denser than previously proposed. (Artwork: Thibaut Roger, NCCR Planet S / ETH Zürich)

Mercury is shrinking and getting smaller

Mercury is shrinking and getting smaller according to latest research because its interior has been cooling down as internal heat leaks away.

NASA scientists have made the first observation of a polar cyclone on Uranus. Using radio antenna dishes of the Very Large Array in New Mexico, they were able to peer below the methane clouds and determine there is circulating air at the planet's north pole that is warm and dry. These images were generated using the microwave observations – from left, in wavelength bands K, Ka, and Q. The average brightness was removed to enhance the contrast, and three different color maps were used to highlight various features. The cyclone is visible at the north pole, seen as a light-colored dot right of center in each image of Uranus. The observations used to generate these images were made in October 2021.

First Observation of a Polar Cyclone on Uranus

NASA scientists used microwave observations to spot the first polar cyclone on Uranus, seen in images as a light-colored dot to the right of center in each image of the planet. The images use waveleng...

This illustration shows the swirling clouds identified by the James Webb Space Telescope in the atmosphere of exoplanet VHS 1256 b. The planet is about 40 light-years away and orbits two stars. The planet’s clouds, which are filled with silicate dust, are constantly rising, mixing, and moving. Credit: NASA, ESA, CSA, Joseph Olmsted (STScI)

James Webb Telescope Spots Swirling, Gritty Clouds on Exoplanet

Researchers observing with NASA’s James Webb Space Telescope have pinpointed silicate cloud features in a distant planet’s atmosphere. The team also made extraordinarily clear detections of water, met...

This stunning black and white false-color view of Saturn's moon Hyperion reveals crisp details across the strange, tumbling moon's surface. Differences in color could represent differences in the composition of surface materials. The view was obtained during Cassini's close flyby on Sept. 26, 2005.
