A tiny traveler has joined Earth in its journey around the Sun. The object, named 2025 PN7, is a quasi-moon, an asteroid whose orbit closely matches Earth’s.

Read news articleUranus and Neptune are often called "ice giants." This is based on the theory that they were made from materials that easily freeze in space, like water and ammonia. However, this label does not come from direct observations, since no spacecraft has visited the two giants since Voyager 2 in the 1980s. Instead, it is drawn from computer models built using the planets’ sizes, masses, densities, and gravity fields. Now, a new study by scientists at the University of Zurich is challenging this idea. It suggests that the two planets may contain more rock than ice....

Read news articleFor the past 30 years, scientists around the world have been searching for planets beyond our solar system. Known as exoplanets, these worlds come in all shapes and sizes, each orbiting its own star. On September 17, 2025, NASA officially confirmed the existence of 6,000 exoplanets. Even more exciting, an additional 8,000 are just waiting to be verified!...
Read news articleThe US space agency NASA needs your help designing the next set of wheels for space vehicles. The "Rock and Roll with NASA Challenge" is hosted on the innovation platform HeroX. It challenges students, engineers, and creative minds to design wheels that can withstand the Moon's harsh conditions. These innovations could shape the future of lunar exploration....
Read news articleA rare comet from another star system is speeding through our solar system, giving astronomers a unique chance to study an interstellar visitor up close. Named 3I/ATLAS, it is only the third such object ever confirmed. It joins Oumuamua, which appeared in 2017, and Borisov, detected in 2019....
Read news articleIn mid-June, over 200 people across the southeastern United States spotted a brilliant fireball streaking across the sky. It was a meteorite that soon slammed into a home in McDonough, Georgia. The space rock ripped through the roof, landing just 14 feet from the startled homeowner. The impact left a small crater on the floor....
