A New FRB Signal Has Buzzed Nearly 2,000 Times in Just Two Months, Raising a Mystery : ScienceAlert

We have detected a strange new signal from across the chasm of time and space. A repeating fast radio burst source detected last year was recorded spitting out a whopping 1,863 bursts over 82 hours, amid a total of 91 hours of observation. This hyperactive behavior has allowed scientists to characterize not just the galaxy that … Read more

Super-Earths Are Bigger and More Habitable Than Earth, and Astronomers Are Discovering More of the Billions They Think Are Out There

Astronomers now routinely discover planets orbiting stars outside of the solar system— they’re called exoplanets. But in summer 2022, teams working on NASA’s Transiting Exoplanet Survey Satellite found a few particularly interesting planets orbiting in the habitable zones of their parent stars. One planet is 30 percent larger than Earth and orbits its star in … Read more

Mars is already TRASHED: Humans have left more than 15,000 pounds of debris on the Red Planet

Humans have left more than 15,000 pounds of trash on Mars in the last 50 years and not a single person has ever stepped foot on the red planet. Cagri Kilic, a postdoctoral research fellow in robotics at West Virginia University, analyzed the mass of all rovers and orbiters sent to Mars and subtracted the … Read more
