In search of a good origin story for the building blocks of life, the authors of this paper have set their sights higher. Literally higher, to exoplanets’ skies.
Planetary radius is found to depend strongly on planet composition. The observed planet radius distribution can be recast as a composition distribution, with implications for the way planets form.
Our Solar System is pretty straightforward. Roughly speaking, all the planets orbit in the same plane, most spin on their axes in the same direction in that plane, and even the Sun rotates in a manner consistent with all this. The small, rocky planets are closer to the Sun, and the big, gaseous planets are farther from the Sun. Simple. Now that we are finding planets orbiting other stars, many are turning out to be multiplanet systems like our own Solar System.
Herschel observations reveal that debris disks are aligned with their stars’ equators, unlike some close-in transiting exoplanets.

Astronomers have found evidence of water in the remains of a planetary system around a white dwarf. This indicates water-rich asteroids can bring water to terrestrial planets, important for the habitability of planets.
This paper asks what the biosphere of the Earth will look like billions of years from now, when the era of life is ending. What biosignatures might we detect from a dying planet?
There’s a new space telescope on the block, which just might find as many new planet candidates as the Kepler mission.
We are used to thinking about planet transits in visible wavelengths. What can we learn from planet transits in the radio band? Today, we discuss what these transits might tell us about the magnetic activity and the atmosphere of a star.
