On Feb. 22, 1906, German astronomer Max Wolf made a discovery that adjusted astronomers’ view of the cosmos and provided proof for the century-old predictions of Joseph-Louis Lagrange. A pioneer in ...

Whether we’re talking about Artemis II—the first crewed lunar mission since the early 1970s—or the launch of NASA’s latest “flagship” astrophysics mission, the Nancy Grace Roman Space Telescope, or ...

Four astronauts will fly around the moon, perhaps as early as next month, on NASA’s Artemis II mission. The three Americans and one Canadian will ride on the Space Launch System in its initial crewed ...

TOKYO, Jan 19 (Reuters) - Olympic gold medallist Ryoyu Kobayashi has said experience had taught him that ski jumping rarely follows a script as he prepares for his third straight Olympics. Japan’s ...

NASA’s Interstellar Mapping and Acceleration Probe (IMAP) reached the Sun-Earth Lagrange point 1 (L1) on January 10, 2026, approximately 1 million miles from Earth toward the Sun, according to NASA.

After a three-and-a-half-month journey, NASA’s Interstellar Mapping and Acceleration Probe (IMAP) has finally reached its destination, a strategic location between the Sun and Earth where it will ...

Even most rocket scientists would rather avoid hard math when they don't have to do it. So when it comes to figuring out orbits in complex three-body systems, like those in cis-lunar space, which is ...

3I/ATLAS is only the third interstellar object ever observed traveling through the solar system, following 1I/'Oumuamua in 2017 and 2I/Borisov in 2019. Each encounter has sparked fascination—and ...

In order for NASA to study the mysteries of the universe, the scientists there need to be able to look out into the cosmos. The Hubble Space Telescope did this for a time, giving humanity some ...
