    Over the decades, NASA has managed to capture a number of astonishing photos from space, showcasing how beautiful the cosmos really is. Take these unique details on Saturn’s moon Iapetus as the perfect example. Or how about an eerie snapshot taken by the so-called ‘most isolated man in the universe?’ These photos have a way of pulling you in and honestly, I could scroll through them for hours on end. I'm not alone; one social media user has re-shared two stunning photos of Uranus captured by NASA which have since gone viral. The US agency launched its James Webb Space...

    Using data from the James Webb Space Telescope (JWST), the astronomers, led by the University of Cambridge, have identified the chemical fingerprints dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) – molecules that indicate life. Here on Earth, these molecules are only produced by living organisms – primarily microbial life such as marine phytoplankton. The molecules have been detected in the atmosphere of exoplanet K2-18b, which is located around 124 light-years from Earth in the constellation of Leo.

    New James Webb Space Telescope (JWST) images show the first carbon dioxide-containing planet discovered outside of Earth’s solar system, displaying the telescope’s ground breaking research capabilities. One hundred thirty thousand lightyears from Earth, the multiplanet system HR 8799 has been a primary target for astronomers studying planet formation. The new research confirms JWST’s ability to measure an exoplanet’s atmospheric chemistry and suggests the four planets formed similarly to Jupiter and Saturn, coalescing around a solid core. Viewing a Young Solar System At only 30 million years old, HR 8799 is relatively young compared to Earth’s 4.6 billion-year-old solar system. Due...

    Artist’s impression of GJ 1214 b passing in front of its host star. The “transit method” allows astronomers to study an exoplanet by seeing which wavelengths of light dim when the star’s light passes through the exoplanet atmosphere. (Credit: NAOJ) Scientists have classified a novel category of exoplanets spotted by the James Webb Space Telescope that appear to have no equivalent in our solar system. This newly proposed category of exoplanet, dubbed “Super Venus,” has often frustrated researchers due to its combination of properties that land it somewhere between Earth and Neptune. A team of researchers believes their analysis of...

    Observations suggest that galaxies are moving apart at a higher rate than scientists have long expected. Many now wonder if the standard model of cosmology can fully explain what’s going on. Dan Scolnic is an associate professor of physics at Duke University. He and his team led a new study, published in the Astrophysical Journal Letters, that strengthens the case for a mismatch between data and predictions. Century of tracking

    The James Webb Space Telescope has found evidence of large, bright galaxies in the early universe, challenging traditional dark matter theories and suggesting a rapid galactic formation as predicted by MOND. Credit: SciTechDaily.com New findings from the James Webb Space Telescope contradict traditional theories about early galaxy formation, revealing large and bright galaxies instead of the expected small, dim structures. This observation supports the Modified Newtonian Dynamics (MOND) theory, which disputes the role of dark matter and suggests a rapid formation of galaxies in the early universe, presenting a challenge to the widely accepted dark matter hypothesis.

    New findings made possible by the James Webb Space Telescope reveal that the Earth-like exoplanet Trappist-1 b may have an atmosphere after all, potentially overturning earlier findings. Approximately forty light years from Earth, seven planets orbit the star Trappist-1, three of which–Trappist-1e, f, and g–exist in the star’s habitable zone and could theoretically be warm enough to allow for liquid water on their surfaces. Since its launch, the James Webb Space Telescope (JWST) has logged 290 hours observing the Trappist-1 system across ten research endeavors. Elsa Ducort of Paris’s Commissariat aux Énergies Atomiques (CEA) led the study team, which analyzed...

    Astronomers using the James Webb Space Telescope to peer back in time into the farthest reaches of the universe have found stunning evidence for an alternate theory of gravity. Current models of galaxy formation in the early cosmos predict the presence of excess gravity caused by dark matter to pull material into slowly forming galaxies. However, an alternate theory of gravity first proposed in 1998 called Modified Newtonian Dynamics (MOND) suggests that structures in the early universe formed very quickly without the need for theoretical dark matter. Now, researchers from Case Western Reserve University say that scans of ancient galaxies...

    The James Webb Space Telescope (Credit: NASA) The James Webb Space Telescope has confirmed controversial Hubble Telescope measurements that seemingly contradict the standard model of cosmology, giving rise to what is known as the ‘Hubble Tension,’ according to new findings involving the most extensive study of the universe’s expansion ever conducted. Confirmation of the decades-long Hubble Tension, which reveals that the universe is expanding faster than cosmological models predict, has sent astrophysicists back to the drawing board in search of previously unknown physics that could account for the measurements, potentially rewriting the standard model. “The discrepancy between the observed expansion...
