Comet C/2026 A1 (MAPS) joins the Kreutz Sungrazing family, making its closest approach to the sun in April 2026, with a potential for broad daylight visibility. Discovered remotely from the Atacama Desert, this comet may offer spectacular views, especially in the Southern Hemisphere.
It is one of the most famous questions in science, asked over lunch by physicist Enrico Fermi. With hundreds of billions of stars and billions of years, life should have emerged many times over. And yet, no signals. No visitors. No evidence of anyone at all.
The universe is 13 billion years old. Our galaxy alone contains hundreds of billions of stars, a significant proportion of which host planets. Many of those planets sit in the right temperature range for liquid water.
Here's a thought experiment that keeps planetary scientists awake at night. Strip every living thing from our planet—every bacterium, every blade of grass, every creature that has ever drawn breath—and ask a simple but profound question: Would Earth still be a world capable of supporting life?
The answer, it turns out, is yes. And that finding has enormous implications for how we search for life beyond our solar system. The problem is subtle but important.
Using the MeerKAT radio telescope, astronomers have discovered a natural "space laser" originating from a violently merging galaxy more than 8 billion light-years away.
When gas-rich galaxies collide, the impact compresses enormous reservoirs of gas. This violent cosmic crash can stimulate molecules—specifically hydroxyl (OH) molecules—causing them to emit incredibly bright, coherent radio waves.
