With a mass and radius that suggest a rocky composition and a temperature that may allow liquid water, this planet could become a key target in the search for extraterrestrial life.","body_html":"<p>In a breakthrough that has excited the exoplanet community, scientists have discovered a super‑Earth located just 25 light‑years from Earth that may support liquid water on its surface. The planet, named GJ 3378b, orbits a dim, red dwarf star and sits comfortably within its star’s habitable zone.</p>n<h2>A New Neighbor in the Search for Life</h2>n<p>Using data from high‑precision radial‑velocity measurements, researchers were able to detect the subtle wobble of the host star caused by the planet’s gravitational tug. The star, a cool M‑type dwarf, is relatively close to our solar system, making GJ 3378b one of the nearest potentially habitable worlds known to date.</p>n<h2>Why GJ 3378b Stands Out</h2>n<ul>n<li>Mass: Roughly 5–10 times that of Earth, placing it in the super‑Earth category.</li>n<li>Radius: About 1.5–2 Earth radii, indicating a dense, rocky composition.</li>n<li>Equilibrium Temperature: Estimated to be between 250 K and 300 K, a range that could allow liquid water if an atmosphere is present.</li>n<li>Orbital Period: Completes an orbit in just a few days, typical for
