This illustration shows the three steps astronomers used to measure the universe's expansion rate to an unprecedented accuracy, reducing the total uncertainty to 2.4 percent. Astronomers made the measurements by streamlining and strengthening the construction of the cosmic distance ladder, which is used to measure accurate distances to galaxies near and far from Earth.

Saturn’s ring current of energetic ions trapped in its magnetic field is shown in this false-color map from the Cassini spacecraft. The colors correspond to the intensities of the energetic neutral atoms emitted from the ring current. These neutral atoms are formed when trapped energetic positive ions take electrons from cold gas atoms, and are then able to escape Saturn’s magnetic field. Credit: NASA/JPL/JHUAPL

Biggest Planets Started out as Tiny Pebbles

August 21, 2015

The sweep of NASA Kepler mission’s search for small, habitable planets in the last six years. The first planet smaller than Earth, Kepler-20e, was discovered in December 2011 orbiting a Sun-like star slightly cooler and smaller than our sun every six days. But it is scorching hot and unable to maintain an atmosphere or a liquid water ocean. Kepler-22b was announced in the same month, as the first planet in the habitable zone of a sun-like star, but is more than twice the size of Earth and therefore unlikely to have a solid surface. Kepler-186f was discovered in April 2014 and is the first Earth-size planet found in the habitable zone of a small, cool M dwarf about half the size and mass of our sun. Kepler-452b is the first near-Earth-Size planet in the habitable zone of a star very similar to the sun.
