How many Earth-like planets are around sun-like stars?
A new study provides the most accurate estimate of the frequency that planets that are similar to Earth in size and in distance from their host star occur around stars similar to our Sun. Knowing the rate that these potentially habitable planets occur will be important for designing future astronomical missions to characterize nearby rocky planets around sun-like stars that could…
Two planets orbiting Teegarden’s star described as most earthlike found yet
A pair of researchers, one with the Hebrew University of Jerusalem, the other Tel Aviv University, has found evidence that suggests two of Teegarden’s star planets are the most Earth-like found yet. In their paper published in The Astrophysical Journal Letters, Amri Wandel and Lev Tal-Or describe their study of the two exoplanets and what they found.

Dragonfly aims for Saturn’s moon Titan
Scheduled for launch in 2026, the Dragonfly mission will look for clues to the origins of life, and possibly even evidence of life itself, on Saturn’s alien yet remarkably Earth-like moon Titan. Source: https://earthsky.org/space/dragonfly-mission-saturn-moon-titan…
Do organic crystals create ‘bathtub rings’ around Titan’s lakes and seas?
Scientists have been trying to figure what creates the so-called “bathtub rings” around lakes and seas on Saturn’s large moon Titan. Now they may have an answer: unusual organic crystals not found on Earth. Source: https://earthsky.org/space/saturn-moon-titan-crystals-bathtub-rings-lakes-seas…
Cool! Teegarden’s Star has Earth-sized planets in its habitable zone
The habitable zone is where liquid water can exist. Teegarden’s Star’s star is only 12.5 light-years from Earth. Astronomers have discovered 2 new Earth-sized exoplanets orbiting in this nearby habitable zone. Source: https://earthsky.org/space/earth-sized-planets-habitable-zone-teegardens-star…
