Earth-like planets may be more common than we thought
- A new study from Rice University suggests that Earth-like planets may be more common in the universe than previously thought.
- The study challenges old ideas by proposing that planets form in narrow rings of material around young stars, rather than from scattered space dust.
- The researchers used N-body models to simulate planet formation and found that super-Earths tend to form closer to the star, while mini-Neptunes form farther out.
- The model also suggests that some Earth-like planets could potentially exist in the habitable zone, where liquid water may be present.

Europe’s first Mars rover will have UK-built lander
- The European Space Agency's (ESA) ExoMars mission, which aims to explore whether life once existed on Mars, is back on track.
- The Rosalind Franklin rover, named after the scientist who discovered the structure of DNA, is part of the mission and will feature a drill to retrieve samples from below the surface.
- The project, initially a joint venture with Roscosmos, was suspended due to the Russian invasion of Ukraine.
- However, ESA secured additional funds and agreements with other sources, including NASA, to continue the mission, with the rover's landing platform set to be built in the UK.

Webb Telescope sees an early galaxy blowing away the cosmic fog
- Scientists studying the early Universe have uncovered an intriguing mystery surrounding a galaxy observed just 330 million years after the Big Bang.
- The galaxy, known as JADES-GS-z13-1, is showing bright hydrogen emissions that should have been absorbed by the cosmic fog, suggesting that the fog may have cleared earlier than previously thought.
- The discovery was made using the James Webb Space Telescope (JWST), which detected intense Lyman-alpha hydrogen emission from the ancient galaxy.
- The findings challenge current theories about the transmission of light and galaxy formation in the early Universe, and further studies are needed to unravel the mystery.

NASA makes first successful detection of Earth’s ambipolar electric field
- NASA's Endurance mission successfully detected Earth's ambipolar electric field after suspicions over half a century.
- The ambipolar electric field, a weak but significant force, aids charged particles in escaping Earth's upper atmosphere near the poles.
- The field was measured for the first time by NASA's Endurance mission through a rocket launched near the North Pole.
- The field acts like an invisible tug-of-war, helping keep charged particles together and lifting them into space.
- Endurance's data showed a tiny electric potential drop of 0.55 volts across a large region above Earth.
- The electric field lifts particles without heating them, allowing ions to escape Earth's atmosphere at supersonic speeds.
- Endurance's mission used a custom photoelectron spectrometer and other instruments to confirm the ambipolar field's strength.
- The field extends Earth's atmosphere, aiding particles in the polar wind to reach escape speeds and leave the atmosphere.
- The measurement of the ambipolar electric field validates long-standing theories and provides insight into planetary atmospheres and potential for life.
- Understanding the ambipolar field's role can help scientists comprehend how Earth's atmosphere evolves and how material is lost into space.

- Missions strategically approach Mars to gain several percent of speed through flybys, with proximity affecting the speed boost, while aiming to avoid atmospheric interference at closest points.
- NASA's Europa Clipper was redirected towards Earth after its Mars flyby to benefit from a second gravity assist en route to Jupiter, showcasing the utilization of planetary motions for space exploration.
- While not the primary purpose of these visits, spacecraft often take the opportunity to observe Mars and its moons, like when Mastcam-Z on Clipper searched for interplanetary objects during its flyby.
- Perseverance rover on Mars has been exploring the 'Sally’s Cove' outcrop, examining dark-colored rocks and leaving spherules behind, offering anticipation for future discoveries.
- The outer solar system-bound missions find Mars flybys crucial for trajectory adjustments, showcasing the significance of utilizing planetary encounters for efficient and accelerated space travel.
- Exploring Mars not only aids in mission calibrations but also presents opportunities to study the Red Planet and its moons, maximizing the scientific gains during interplanetary voyages.
- Integrating Mars flybys into space missions exemplifies the intricate dance between planetary bodies and spacecraft trajectories, demonstrating the strategic planning involved in interstellar exploration.
