Wind the cosmic clock back a few billion years and our Solar System looked much different than it does today. About 4.5 billion years ago,…
Astronomers have announced evidence for a possible planet in another galaxy. This “exoplanet” would be much farther away than any of the thousands of others…
The surface of Venus is utterly inhospitable for life: barren, dry, crushed under an atmosphere about 90 times the pressure of Earth’s, and roasted by…
NASA’s Perseverance rover captures a geologic feature with details that offer clues to the area’s mysterious past. Ask any space explorer, and they’ll have a…
