A "Second Jupiter" Discovered

  Astronomers in the Strategic Explorations of Exoplanets and Disks with Subaru (SEEDS) Project have recently discovered and captured an image of the least massive planet ever imaged so far, a so-called “second Jupiter” (Figure 1). This discovery marks an important step toward the direct imaging of much fainter Earth-like planets in the future and [continue reading]

How Ordinary is Our Planet?

  It’s the default premise in science: If you observe something in nature only once, you assume that what you’ve seen is typical. That’s because “typical” is just another way of saying “most probable.” Consequently, ever since Copernicus redrew the blueprint of the Cosmos nearly five centuries ago, we’ve assumed that there would be other planets [continue reading]

The Sun's Future Unveiled

  A team of astronomers led by Jose Dias do Nascimento (Department of Theoretical and Experimental Physics, Universidade Federal do Rio Grande do Norte [DFTE, UFRN], Brazil) has found the farthest known solar twin in the Milky Way Galaxy, CoRoT Sol 1, which has about the same mass and chemical composition as the Sun. Figure [continue reading]

Far-Off Planets Studied by Using New Method

  A University of Washington astronomer is using Earth’s interstellar neighbors to learn the nature of certain stars too far away to be directly measured or observed, and the planets they may host. Current list of potentially habitable exoplanets including Kepler-61b. Earth, Mars, Jupiter, and Neptune were added for scale. Image Credit: Planetary Habitability Laboratory @ [continue reading]

Three Super-Earths in 'Habitable Zone' Discovered

  NASA’s Kepler mission has discovered two new planetary systems that include three super-Earth-sized planets in the “habitable zone,” the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water. Relative sizes of Kepler habitable zone planets discovered as of April 18, 2013. Left to [continue reading]

The Smallest Exoplanet Found So Far!

  NASA’s Kepler mission scientists have discovered a new planetary system that is home to the smallest planet yet found around a star similar to our Sun. The artist’s concept depicts the new planet dubbed Kepler-37b. The planet is slightly larger than our Moon, measuring about one-third the size of Earth. Kepler-37b orbits its host [continue reading]
