Temperate exoplanet LHS 1140 b may be a world completely covered in ice (left), similar to Jupiter’s moon Europa, or an icy world with a liquid substellar ocean and a cloudy atmosphere (center). LHS 1140 b is 1.7 times the size of Earth (right) and is the most promising exoplanet in the habitable zone found … Read more
An exoplanet in its star’s habitable Goldilocks zone is now suspected of having a liquid water ocean and an atmosphere. The planet, called LHS 1140 b, is about 1.7 times the size of Earth and is located about 48 light-years away. This distant world, first discovered in 2017, now turns out to be a rocky … Read more
Using the James Webb Space Telescope (JWST), astronomers have observed the dramatic “dance” between a supermassive black hole and two satellite galaxies. The observations could help scientists better understand how galaxies and supermassive black holes grew in the early universe. This particular supermassive black hole is feeding on surrounding matter, powering a bright quasar that … Read more
Researchers using the James Webb Space Telescope have studied the interaction of a quasar with satellite galaxies, gaining crucial insights into the growth of galaxies in the early universe, the mass of black holes, and chemical evolution. (Artistic concept.) Credit: SciTechDaily.com An international research group used the James Webb Space Telescope to witness the dramatic … Read more
New observations of Jupiter’s Great Red Spot have revealed that the planet’s atmosphere above and around the infamous storm is surprisingly interesting and active. This image shows the region Webb observed – first the location on a NIRCam image of the entire planet (left), and then the region itself (right), imaged by Webb’s Near-InfraRed Spectrograph … Read more
Researchers investigated three mysterious objects in the early universe. Shown here are their color images, compiled from three NIRCam filter bands aboard the James Webb Space Telescope. They are remarkably compact at red wavelengths (earning them the name “little red dots”), with some evidence of spatial structure at blue wavelengths.

This new image from NASA’s James Webb Space Telescope shows a young protostar in the process of forming inside a fiery, hourglass-shaped molecular cloud. Captured with the MIRI instrument, the scene reveals dynamic outflows and bright regions caused by interactions with surrounding gases and dust.

This image is a mosaic of visible light and infrared views of the same frame from the Pillars of Creation visualization. The three-dimensional model of the pillars created for the visualization sequence is displayed alternately in the Hubble Space Telescope version (visible light) and the Webb Space Telescope version (infrared light).

9 Using the joint NASA, European Space Agency (ESA) and Canadian Space Agency (CSA) James Webb Space Telescope, a group of scientists have discovered a variety of never-before-seen features in Jupiter’s upper atmosphere. The features were found in the atmospheric region above the iconic Great Red Spot, a high-pressure area in Jupiter’s atmosphere that creates … Read more
The gleaming towers of cosmic dust and gas at the heart of the Eagle Nebula have inspired awe for decades since they were first captured by the Hubble Telescope. Now NASA issued the most detailed visualization of the iconic celestial structure, revealing all its dreamlike features across multiple wavelengths of light. Webb telescope visualizes the … Read more
