The Webb Space Telescope has found no evidence of an atmosphere at one of the seven rocky, Earth-sized planets orbiting another star. Scientists said Monday that doesn’t bode well for the rest of the planets in this solar system, some of which are in the sweet spot for harboring water and potentially life. “This is not necessarily a bust” for the other planets, Massachusetts Institute of Technology astrophysicist Sara Seager, who wasn’t part of the study, said in an email. “But we will have to wait and see.” The Trappist …

Scientists have long known that wild seabirds ingest bits of plastic pollution as they feed, but a new study Monday shows the tiny particles don’t just clog or transit the stomach but can subvert its complex mix of good and bad bacteria, too. Plastic-infested digestive tracts from two species of Atlantic seabirds, northern fulmars and Cory’s shearwaters, showed a decrease of mostly beneficial “indigenous” bacteria and more potentially harmful pathogens. There was also an increase in antibiotic-resistant and plastic-degrading microbes, researchers reported in the journal Nature Ecology & Evolution. The …

Florida has captured more than 17,000 Burmese pythons since 2000, but tens of thousands more are likely roaming the Florida Everglades. That’s a concern because the reptiles, which are not native to the area, are gobbling up the competition. “[Pythons] can take out one of our apex predators, which are alligators and crocodiles, and then it’ll take down some of the other native animals that are small mammals — some of the rats, the mice, the marsh bunnies — things that are supposed to be food for other things,” says …

Keep an eye to the sky this week for a chance to see a planetary hangout. Five planets — Mercury, Jupiter, Venus, Uranus and Mars — will line up near the moon. Where and when can you see them? The best day to catch the whole group is Tuesday. You’ll want to look to the western horizon right after sunset, said NASA astronomer Bill Cooke. The planets will stretch from the horizon line to around halfway up the night sky. But don’t be late: Mercury and Jupiter will quickly dip …
