But in recent years, astronomers have begun to find compact objects that emit pulses of radio waves at a much slower rate. This has baffled scientists, who had thought that radio wave flashes ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has detected a new grand-design spiral galaxy as part of the PANORAMIC survey. The newfound galaxy, named ...

Then, astronomers watched as the so-called X-ray corona of high-energy particles close in to the black hole vanished — only to slowly reform over time. The most likely cause of this strange ...

Of all the mysteries that the massive James Webb Space Telescope has seen so far in the early universe, one of the strangest are objects that astronomers now call "little red dots." Like the ...

As an astronomer, I have been teaching college students and visitors to our planetarium how to find stars in our sky for more than 20 years. As part of teaching appreciation for the beauty of the ...

But if astronomers determine a white dwarf is indeed causing the pulses, it could make the site more desirable for LISA to observe. “Everyone really wants to see a white dwarf get eaten by a ...

For stargazers and wildlife watchers, monoculars can be an effective alternative to telescopes or binoculars. Here's how they work. Want to bring the cosmos closer without breaking the bank or ...

Jan. 13, 2025 — Astronomers observed flashes of X-rays coming from a supermassive black hole at a steadily increasing clip. The source could be the core of a dead star that's teetering at the ...

When you gaze up at the constellation Hercules, you are looking out the front window of the spacecraft called Earth. Our planet is hurtling at some 45,000 mph (72,000 km/h) toward the star Lambda ...
