Among the roughly 10 billion white dwarf stars in the Milky Way galaxy, a greater number than previously expected could ...

Keep your eye on the ball” is a motto for many athletes—and for astronomers trying to find Earth-threatening space rocks ...

YARARA proved vital in the effort to confirm HD 20974d as being real. What's most remarkable about this new planet, however, is its orbit. While Johannes Kepler taught us that no planetary orbit is ...

To find a planet on an orbit similar to our own, Kepler would have to monitor the star for several years to confirm that the dips repeated. Scaled up, that meant that Kepler needed to watch one ...

To see this, recall the definition of angular momentum: Kepler's second law states that the area swept out by the line connecting the satellite to the Earth's center over a given time Δt is a constant ...

New insights into the extreme conditions behind "disintegrating planets" reveals how they are consumed by the heat of their ...

Kepler-62f (also known by its Kepler Object ... But Kane warns that any small adjustments to the orbit and “things would go poorly.” In iterations where the additional planet didn’t ...

Together with precise optical ranging between selected satellites, this provides orbit determination capabilities with unprecedented accuracy. The Kepler infrastructure thus consists of three main ...

As of early 2012, Kepler has uncovered 17 stars with multiple planets as well as a new class of planets that orbit double and even triple stars. But only a handful of the exoplanets discovered so ...

Moreover, with truly prescient insight, Kepler suggested that the planets were kept in orbit by a force emanating from the sun itself. This radical idea was eventually demonstrated by Isaac ...
