Humans have lived on planet Earth for millennia, and our advances during those years have led us to understand that worlds and galaxies exist beyond our own. Many other planets exhibit tantalising hints that they may be capable of supporting life, and so our minds are drawn to the idea of ...
In 3 billion years, the human race, unless it has got off this planet, will no longer exist because the Sun would have made the planet inhabitable. This YouTube video that NASA shared explains more about the Galaxies' merging and how the Milky Way and Andromeda galaxies will merge....
that resemble a pattern. Constellations are areas of the sky where we have broken the sky into parts. All the stars in the constellations are withinthe Milky Way. A galaxy is a large collection of stars containing billions or trillions of stars. Galaxies exist outside our own Milky Way ...
Axions are ultra-light particles that could exist in large numbers and act like a cold, invisible fluid throughout space. They’re another strong candidate for dark matter, especially since they might help solve other physics puzzles, such as the strong-CP problem in particle physics. Sterile n...
Cygnus A is one of the most prominent examples of a radio galaxy, but other exceptional radio-loud supermassive black hole-powered galaxies exist in the universe. Centaurus A, also known as Caldwell 77 or NGC 5128, is located around 12 million light-years from Earth, making it one of the...
Their survey was the first to indicate that galaxies were not distributed uniformly in space. Some areas had a lot of galaxies, and other areas had just a few. Another way of putting this is to say that galaxies are clustered. They're not spread evenly throughout the universe. So we hav...
Since the launch of NASA's James Webb Space Telescope (JWST), the agency has made several profound discoveries and put out some of the most stunning images of galaxies and nebulae that exist. In 2024, the telescope again pushed the boundaries of our understanding of the universe by identifying...
the Oh-My-God particle, the cosmic ray’s energy shocked astrophysicists. Nothing in our galaxy had the power to produce it, and the particle had more energy than was theoretically possible for cosmic rays traveling to Earth from other galaxies. Simply put, the particle should not ...
They can even absorb other stars. Many scientists think that there are super-massive black holes at the center of galaxies."This special black hole, which is about 30 billion times the mass of our sun, is one of the biggest ever discovered.* It is an exciting discovery," said James ...
Our knowledge of galaxy types and their distribution suggests that life as we know it can only exist in about 10% of all galaxies. Luckily for us, our galaxy, the Milky Way is one of them, it is a galaxy that is suitable for life. Image: “Milky Way over the Lake Tekapo” on ...
