The James Webb Space Telescope's observations provide conflicting values for the rate of cosmic expansion, failing to settle the disagreement over the Hubble constant. [ more ]

JWST spotted an extremely red supermassive black hole in a distant location.

The black hole's uniqueness challenges existing understanding of how such entities grow relative to host galaxies. [ more ]

The James Webb Space Telescope (JWST) detected a neutron star in the core of the famous supernova (SN) 1987A explosion.

JWST observed light from ionized atoms around the neutron star, confirming its presence behind the dust veil from the explosion. [ more ]

NASA's James Webb Space Telescope and Hubble Space Telescope continue to provide stunning images of the cosmos.

The 12 best space images of 2023 include a dancing galaxy pair, taffy-like galaxies, and the Spare Tire Nebula. [ more ]

Water is essential for life and plays a significant role in planet formation.

Astronomers are utilizing the James Webb Space Telescope to study water in protoplanetary disks. [ more ]

Space telescopes like Hubble and James Webb are located in space to get a clearer view of objects in outer space.

Putting telescopes in space allows astronomers to avoid atmospheric effects like twinkling stars and get sharper images. [ more ]

In the future, the sun will die and become a white dwarf, consuming the inner planets but potentially leaving the outer planets intact.

Astronomers have used the James Webb Space Telescope to detect evidence of giant exoplanets still orbiting white dwarfs. [ more ]

The James Webb Space Telescope (JWST) has observed bright galaxies that stretch back to the early universe, which is puzzling because galaxies shouldn't have had enough time to become so massive.

Studies suggest that the unexpected girth of these early galaxies could be attributed to astrophysical explanations like earlier-forming black holes or bursts of star formation, rather than a flaw in our understanding of cosmology. [ more ]

Astronomers have spotted two gas giant exoplanets orbiting the remains of white dwarf stars, which is unusual due to the extreme forces involved.

The discovery suggests that gas giants could survive their hot stars collapsing and transforming into white dwarfs, but further confirmation is still needed. [ more ]

Detailed views of spiral galaxies captured by NASA's James Webb Space Telescope (JWST) in near and mid-infrared light

Comparison of these images with previous views from Hubble telescope in visible and ultraviolet light reveals new galactic structures and elements [ more ]

The James Webb Space Telescope (JWST) recently captured an image of one-third of the N79 nebula, a giant cloud of cosmic dust.

The JWST studies the cosmos in the infrared, which is invisible to the human eye but visible to instruments like the JWST telescope. [ more ]

The James Webb Space Telescope discovered Jupiter-sized objects drifting in space with no stars to orbit

A team of Mexican scientists found that one of the objects, JuMBO 24, was giving off a steady radio signal [ more ]

Astronomers have discovered the oldest black hole ever observed, formed just 400 million years after the Big Bang.

The black hole is so large for its age that it challenges current theories on how these objects form. [ more ]

The James Webb Space Telescope has sparked speculation among scientists about the possibility of finding signs of alien life.

No definitive evidence has been found so far, but the telescope's observations could lead to the initial identification of potential biosignatures. [ more ]

NASA unveils new image of the Milky Way taken by the James Webb Space Telescope, showing needle-like structures that have scientists intrigued.

The image reveals 500,000 stars, protostars, and feathery wisps believed to be emissions from ionized hydrogen.

Scientists are puzzled by the needle-shaped structures and are determined to gather more data to understand them. [ more ]

The James Webb Space Telescope (JWST) captured new images of the heart of the Milky Way, revealing insights into the origin of the universe.

The images offer clues about how a cosmic environment impacts star formation and show previously unseen details of the galactic center.

JWST's Near-Infrared Camera (NIRCam) captured a dense and abundant star-forming region called Sagittarius C, including a pink pocket of massive protostars. [ more ]

The James Webb Space Telescope has captured an image of a star-forming region named Sagittarius C, 300 light-years from the Milky Way's central black hole.

The image contains about 500,000 stars and will provide important insights into stellar formation.

The image shows a dense cluster with a massive protostar and smaller infrared-dark clouds where future stars are forming. [ more ]

The James Webb Space Telescope (JWST) has captured an image of the heart of the Milky Way in unprecedented detail.

The image shows over 50,000 stars and chaotic clouds at the galactic center, providing new insights into star formation in this extreme environment.

JWST's infrared camera, NIRCam, was used to capture the image and detect light from the earliest stars and galaxies in formation. [ more ]

Nasa's James Webb space telescope has made groundbreaking observations of the planet Wasp-107b.

Wasp-107b is a large but very light planet located 200 light years away from Earth.

The planet features silicate sand clouds and rain, scorching temperatures, raging winds, and the smell of sulphur dioxide. [ more ]
