There are constant reminders in our daily environment of the many chapters of life that have unfolded on Earth. Rocks and dirt preserve traces of the eras that preceded ours, such … Read more
Astronomers have used the James Webb Space Telescope (JWST) and predicted an effect by Albert Einstein more than 100 years ago to discover that small galaxies packed a huge punch in the early cosmos, forming the entire universe when it was less than 1 billion years old. The international team found that the galaxies, which … Read more
The James Webb Space Telescope’s infrared view has transformed our view of a large barred spiral galaxy, revealing its skeleton of dust illuminated by the glow of young stars. Visible-light images of NGC 1559, such as those taken by the Hubble Space Telescope, show a glowing vortex of light with bright, young star clusters spread … Read more
Using the James Webb Space Telescope (JWST), astronomers have discovered an ‘extremely red’ supermassive black hole growing in the shadowy early universe. The red hue of the supermassive black hole, seen as it appeared about 700 million years after the Big Bang, is the result of the expanding universe. As the universe moves outward in … Read more
Using the James Webb Space Telescope (JWST), astronomers have ended a nearly decade-long game of hide-and-seek in the sky after discovering a neutron star in the wreckage of a stellar explosion. Supernova 1987A represents the remains of an exploded star that once had a mass about 8 to 10 times that of the Sun. It … Read more
Scientists have analyzed an unusually long explosion of high-energy radiation known as a gamma-ray burst (GRB) and determined that it came from the collision of two ultra-dense neutron stars. More importantly, this result helped the team observe a flash of light arising from the same event, confirming that these mergers are the locations that create … Read more
“Which came first: the galaxy or its monstrous black hole?” Technically, it’s an even older riddle than the chicken or the egg, even though we only became aware of it relatively recently. And according to new research, scientists may finally have an answer. It has long been believed that supermassive black holes that existed close … Read more
As the James Webb Space Telescope (JWST) examines small and bright galaxies in the early universe, it may shed light on dark matter – the universe’s most mysterious matter. That is the conclusion of scientists at the University of California, who conducted a simulation of the cosmos that tracks the formation of small galaxies – … Read more
The James Webb Space Telescope (JWST) has already proven itself adept at peering into the past by imaging objects at enormous distances, but a new breakthrough may have made the powerful instrument behave almost like a scientific crystal ball behaves, staring into Earth’s distant future. solar system. The JWST carried out its prediction when it … Read more
A look into the future of exoplanet science suggests the coming European extremely large telescope (ELT) will give us the best chance of detecting nearby biosignatures over the next twenty years rocky worlds orbiting other stars. That’s the conclusion of a new study that simulated what it would take to characterize worlds beyond our solar … Read more
