Scientists have reacted with alarm to news that the British government will cut funding to the world-famous radio telescope at the Jodrell Bank Observatory, a UNESCO World Heritage Site in northwest England that has been helping explore the cosmos for almost 70 years.

Long before a human ever sets foot on the Red Planet, we already know how harsh the environment is. Once a human finally does, the only things protecting them from that environment will be the infrastructure we’ve built there and the spacesuit that keeps them in a protective bubble. Unfortunately, modern spacesuits aren’t built with […]

Sixty-six million years ago, the six-mile-wide (10-kilometer-wide) Chicxulub asteroid crash-landed in Mexico’s Yucatán Peninsula and changed life on Earth forever. The reign of the dinosaurs ended, and only creatures that could shelter in burrows or shallow waters survived into the age of mammals that followed.

More than 20 years after NASA’s Spirit rover landed on Mars, a researcher from Edith Cowan University (ECU) has uncovered new evidence that suggests water may once have covered large parts of the red planet.

At long last, astronomers have firm evidence that Betelgeuse, one of the most famous stars in the night sky, is not alone. Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), a team led by French researcher Miguel Montargès obtained the clearest image yet of what is likely Betelgeuse B, the star orbiting Betelgeuse. […]

We’ve been covering the journey of the Habitable Worlds Observatory for some time now. Over the past few years, it’s gone from a proposal to a relatively fleshed-out plan for how and what the next Great Observatory should do—in this case, look at and characterize potentially habitable exoplanets.

Mercury was long considered the exception to the rule that magnetic planets have radiation belts similar to Earth’s Van Allen belts, but a new study by University of Michigan Engineering and the University of California, Berkeley, suggests otherwise—Mercury occasionally has such a layer of radiation in its magnetic field.

Quasars, distant cores of galaxies powered by supermassive black holes, are among the most luminous objects in the universe. While not uncommon, their brightness can make it difficult to accurately measure the galaxies they reside in. This means scientists must use gravitational lensing to assist in analyzing these bright objects, a method that relies on […]
