In 2019, astronomers spotted something incredible in our backyard: a rogue comet from another star system. Named Borisov, the icy snowball traveled 110,000 miles per hour and marked the first and only interstellar comet ever detected by humans.
But what if these interstellar visitors-comets, meteors, asteroids and other debris from beyond our solar system-are more common than we think?

Over the last two decades, scientists have found ice in many locations on Mars. Most Martian ice has been observed from orbital satellites like NASA's Mars Reconnaissance Orbiter. But determining the grain size and dust content of the ice from that far above the surface is challenging.

The Sun has a new neighbor that was hiding in plain twilight. An asteroid that orbits the Sun in just 113 days-the shortest known orbital period for an asteroid and second shortest for any object in our Solar System after Mercury-was discovered by Carnegie's Scott S.

An interplanetary mission led by the University of California, Berkeley, to put two satellites - dubbed "Blue" and "Gold" - into orbit around Mars has been officially authorized to prepare for launch in October 2024.
The announcement last week by NASA means that by 2026 the spacecraft will likely be exploring the red planet's atmosphere and its interaction with the solar wind.

At least 70% of the very-high-energy gamma rays emitted from cosmic rays are due to relativistic protons, according to the novel imaging analysis of radio, X-ray, and gamma-ray radiation.

Water is life, on Earth and in space. Dutch ESA astronaut André Kuipers recounts his experience living in space for 204 days, and his time looking back on the blue face of ‘Planet Aqua’, comparing notes with divers about what is going on beneath the waves. He goes on to explore how space technology is being used for water management, from orbital tracking of water quality and pollution to spacecraft-grade recycling systems deployed down on the ground, as well as ambitious efforts to identify marine plastic litter using satellites.
