The wavelengths of radio light are so large that you can’t capture a high-resolution image with a single dish. To capture an image as sharp as, say, the Hubble telescope, you’d need a radio dish tens of kilometers across. So radio astronomers took a different approach. They used an array of dozens of antennas, each […]

Some are simply conspiracy theories about it being an alien spacecraft, while others have been well-thought-out suggestions, like using Martian-based probes to observe the comet as it streaked past the red planet. A new paper pre-published on […]

By combining the power of ground-based and space-based telescopes, astronomers have discovered a new brown dwarf—a type of object that lies between a star and a planet—orbiting a small star about 55 light-years from Earth. In addition, infrared observations revealed variations in its brightness, suggesting that clouds and storms may be forming and moving within […]
