Its thick atmosphere holds in so much heat, and the surface is blazing enough to melt lead. But at one point, Venus might have been similar to Earth, a planet with lots of water. A new study published in Nature, found that hydrogen atoms in Venus' atmosphere, needed for water, may have escaped to space. The find, simulated with computer modeling, might ex ...read more

Even massive freighters have sunk to the sea floor.Although shipwrecks may seem like part of the Great Lakes’ past, advancing technology is helping researchers understand the weather patterns that have made so many voyages fatal. Technology is also helping scientists find sunken vessels that were once thought to be lost for ...read more
To the untrained eye, cicadas may look extremely similar to each other, characterized by their hard exoskeleton and distinctive drone. But, as millions of residents of the southeastern and midwestern United States will soon discover in the spring of 2024, the different species of cicadas can vary widely in everything from their sound to their appearance to their behavior. Two broods of cicadas — Broods XIX and XIII — are expected to emerge from the ground, culminating their life cycle by ...read more
