We might be one step closer to an answer for the intriguing cosmic mystery of fast radio bursts. By examining multiple “radio colors” simultaneously in a batch of repeating signals, astronomers have ruled out a leading model for their origin.

In the hunt for extraterrestrial life, most of our attention has been focused on Earth-like worlds. But now, astronomers have defined a new class of exoplanet called “Hycean” worlds that could be a promising place to find signs of life.

NASA’s Curiosity rover has been exploring Gale crater for nine years, studying sediments that look an awful lot like those left behind from an ancient lake. But new research from the University of Hong Kong proposes a much drier explanation.

The BepiColombo orbiter probe passed within 552 km (343 miles) of Venus as it completed one of nine flybys on its way to Mercury. Shortly after the encounter, the ESA/JAXA mission snapped a picture of Venus at a distance of 1,573 km (977 miles).

NASA is planning to send a rotorcraft to Saturn's moon Titan, one of the most intriguing places in the solar system. Now the science goals and objectives for the Dragonfly mission have been outlined, with the search for life high on the list.

Lockheed Martin is looking to give diminutive CubeSats a pretty big job – regularly updating existing satellite constellations in orbit. LINUSS is a new CubeSat family designed to demonstrate technologies to perform such tasks.

Two deep-space probes will make flybys of Venus within 30 hours of each other on their way to the inner reaches of the solar system next week. On August 9, the Solar Orbiter will pass by the planet, followed by the BepiColombo orbiter on August 10.

On June 26, ESA's OPS-SAT space lab went into Earth orbit with a computer running the European Ground System – Common Core (EGS-CC) "space brain" software that will be common to all European space missions from 2025.

A new mathematical study suggests that the abandoned Ascent Stage of the Apollo 11 mission's Eagle Lunar Module, long believed to have crashed on the Moon in 1969, may be circling our largest natural satellite in a stable orbit.

In 2018 astronomers announced the discovery of lakes of liquid water on Mars at the south pole. Sadly, a trio of new papers refutes the claim, with new experiments suggesting that the “water” signal was more likely produced by frozen clay instead.

Black holes are notoriously dark objects, but now astronomers have spotted strange light coming from behind one. The X-ray echoes seem to be the result of the intense gravity of the object warping space and bending the light back around into view.

Controversial physicist Avi Loeb is on the hunt for aliens again. His new Galileo Project aims to track unexplained oddities in the sky, study interstellar objects, and even examine the "possibility" of alien satellites watching us from orbit.
