In this episode of SpaceTime , we explore some of the most exciting recent discoveries in astronomy, including the largest Oort Cloud comet ever observed and remarkable achievements from NASA's Mars Perseverance Rover.

Comet C/2014 UN271 Bernardinelli-Bernstein: A Giant from the Oort Cloud

Astronomers have made a groundbreaking discovery by detecting molecular activity in Comet C/2014 UN271 Bernardinelli-Bernstein, the largest and most distant active comet ever observed. Originating from the Oort Cloud, this colossal comet measures nearly 140 km across, revealing complex jets of carbon monoxide gas and providing insight into its behavior far from the Sun. Observations from the Atacama Large Millimeter/Submillimeter Array (ALMA) in Chile have confirmed its status as the largest known Oort Cloud comet, offering a rare glimpse into the chemistry and dynamics of these distant celestial objects.

Nasa's Perseverance Rover Sets New Distance Record

NASA's Mars Perseverance Rover has achieved a new milestone, traveling 411 meters in a single autonomous drive while exploring the Jezero Crater. This episode highlights the rover's innovative AUTONAV self-driving system and its 30th Abrasion Study of a Martian rock named Kenmore. The findings reveal significant mineral compositions, including clay minerals, iron, and magnesium, enhancing our understanding of Mars' geological history and potential past habitability.

Exoplanets Triggering Stellar Flares

Astronomers have discovered that certain exoplanets in close orbits around their host stars can trigger powerful stellar flares, leading to atmospheric erosion over time. This groundbreaking finding, reported in the journal Nature, demonstrates the interaction between planets and their stars in a way never before observed. The study, conducted using the European Space Agency's CHEOPS spacecraft, reveals that these energetic flares can significantly impact the evolution of the orbiting planets, providing new insights into the dynamics of stellar systems.
