'Iceball' planet discovered through microlensing

Science Daily: Comets and Asteroids -

Scientists have discovered a new planet with the mass of Earth, orbiting its star at the same distance that we orbit our sun. The planet is likely far too cold to be habitable for life as we know it, however, because its star is so faint. But the discovery adds to scientists' understanding of the types of planetary systems that exist beyond our own.

Cygnus Spacecraft Approaches Space Station in the Sunset

NASA: Image of the Day -

On Saturday April 22, 2017, Expedition 51 Flight Engineer Thomas Pesquet of the European Space Agency photographed Orbital ATK's Cygnus spacecraft as it approached the International Space Station. Using the station's robotic Canadarm2, Cygnus was successfully captured by Pesquet and Commander Peggy Whitson at 6:05 a.m. EDT Saturday morning.

Lull in Mars' giant impact history

Science Daily: Mars -

From the earliest days of our solar system's history, collisions between astronomical objects have shaped the planets and changed the course of their evolution. Studying the early bombardment history of Mars, scientists have discovered a 400-million-year lull in large impacts early in Martian history.
