We think of galaxies as ancient. Our galaxy, Milky WayIt was formed 13.6 billion years ago and James Webb Space Telescope allowed us to look back some of the first galaxies in the early universe. So are galaxies still being born today? This is a fun question to tackle because it gives us the opportunity… Read More »
Using the James Webb Space Telescope (JWST), astronomers have discovered clusters of stars in the “Cosmic Stones” arc that existed only 460 million years after the Big Bang. This marks the first discovery of star clusters in a newborn galaxy, seen when the 13.8 billion-year-old universe was less than 500 million years old. Originally discovered… Read More »
Eventually all galaxies, including our Milky Way, will come to an end. So how do galaxies die? If you’re in the mood to destroy an entire galaxy, you have a few options depending on the level of destruction you want. Relating to: Monstrous black holes may have killed host galaxies in the early universe Option… Read More »
Star Wars fans will certainly enjoy the binary star systems, nicknamed the “Tatooine” systems, a reference to the planet on which Luke Skywalker stood to gaze at the twin suns in Star Wars: A New Hope. It turns out that some planets in real-life versions of these systems may also be receiving a much more… Read More »
New research answers an important detail about how galaxies age, showing that the more advanced a galaxy is, the more chaotic the orbits of its stars collectively become. our sun orbits its center Milky Way galaxy every 225 million years, at an average speed of 514,495 mph (828,000 km/h). Astronomers call this a “galactic year.”… Read More »
The James Webb Space Telescope (JWST) has zoomed into the heart of the Cigar Galaxy, a region of space engulfed in flames by an explosive period of star birth. At the core of this starburst galaxy, also known as Messier 82 (M82), is a compact but turbulent environment that could give scientists a clearer picture… Read More »
A neutron star is the remains of a once massive star that died in a supernova explosion. As a whole, neutron stars are considered some of the most extreme objects in the known universe – and this is especially true when these incredibly dense stellar remnants exist alongside companion stars (that are not yet “dead”)… Read More »
NASA’s James Webb Space Telescope (JWST) is known for capturing our universe with unprecedented sensitivity and sensitivity. His images are not only scientifically useful but also beautiful. Of blue and gold Southern Ring Nebula pink, orange and purple Cassiopeia A.JWST images show the universe in bright colors. The images are so impressive that you may… Read More »
“What came first, the galaxy or its monster black hole?” Technically, this is a much older riddle than the riddle about the chicken or the egg; although we only became aware of this relatively recently. And according to new research, scientists may finally have an answer. Supermassive black holes, which existed near the dawn of… Read More »
