Kepler Finds a Very Wobbly Planet

This illustration shows the unusual orbit of planet Kepler-413b around a close pair of orange and red dwarf stars. The planet’s 66-day orbit is tilted 2.5 degrees with respect to the plane of the binary star’s orbit. The orbit of the planet wobbles around the central stars over 11 years, an effect called precession. […]

Gravity-Bending Find Leads to Kepler Meeting Einstein

This artist’s concept depicts a dense, dead star called a white dwarf crossing in front of a small, red star. The white dwarf”s gravity is so great it bends and magnifies light from the red star. Image credit: NASA/JPL-Caltech

NASA’s Kepler space telescope has witnessed the effects of a dead star bending the light […]

Hubble Breaks Record in Search for Farthest Supernova

Since its inaugural deployment from the shuttle in April 1990, the Hubble Space Telescope has peered deeper into the cosmos than ever before in human history. The recent discovery of Supernova SN Wilson—more than 10 billion years old—refines scientists’ yardstick for the age of the Universe. Photo Credit: NASA

More than two decades since […]
