If you can get your hands on a telescope, there are few sights more spectacular than the magnificent sight of Saturn’s rings. Currently, Saturn is clearly visible in the evening sky, at its highest just after sunset. It’s the ideal time to use a telescope or binoculars to get a good view of the Solar ...
Our Sun is a steady and everlasting companion. Reliable like a clock, its apparent passage across the sky allows us to measure time. The Sun and its path is also the source of Earth’s seasons. But in many respects, our Sun is far from calm and unchanging. Close up, the Sun shows extensive variation and ...
Every day and night, hundreds of thousands of intense, brief flashes of radiation suddenly flicker on and then off all across the sky. These “fast radio bursts” are invisible to the naked eye, but to a radio telescope, many almost outshine everything else in the sky for a few thousandths of a second. Since the ...
Every so often, astronomers glimpse an intense flash of radio waves from space — a flash that lasts only an instant, but puts out as much energy in a millisecond as the Sun does in a few years. The origin of these “fast radio bursts” is one of the greatest mysteries that astronomers are searching ...
Of all the objects in the Solar System, perhaps the most spectacular are the great comets that occasionally grace our skies. If you’ve been on social media in the past few days, you’ve probably seen articles proclaiming we have such a comet in our skies right now: C/2023 P1 (Nishimura). As I write this, comet ...

Or is there life somewhere else? Usually, the question inspires visions of weird, green versions of humans. However, life is more ...
A galaxy can come in many shapes and sizes, from giant, slowly rotating ovals and fast-whirling spiral disks to faint ball-shaped blobs and dwarf irregulars. Most large, bright galaxies — including our own Milky Way — are orbited by a gang of much smaller dwarf galaxies. Most of this we know from optical images, whether ...
Rapid progress in artificial intelligence (AI) has spurred some leading voices in the field to call for a research pause, raise the possibility of AI-driven human extinction, and even ask for government regulation. At the heart of their concern is the idea that AI systems might become so powerful we lose control of them. But ...
Our Milky Way galaxy is an awe-inspiring feature of the night sky, viewable with the naked eye as a hazy band of stars stretching from horizon to horizon. For the first time, the IceCube Neutrino Observatory in Antarctica has produced an image of the Milky Way using neutrinos — tiny, ghost-like astronomical messengers. In research ...
