One Year on Earth – Seen From 1 Million Miles

Every two hours, NASA's Epic camera on NOAA's DSCOVR satellite captures a set of images from its L1 (Lagrange point 1) orbit. The images of Earth's sunlit side are taken in ten different wavelengths. The first color-a...

Gravitational Waves Explained Using Stick Figures

How are gravitational waves made? In this episode of MinutePhysics, Henry Reich draws up a series of other wave creating scenarios -- water waves, air pressure waves, and radio waves -- to help explain gravitational w...

Juno: Piercing Jupiter’s Clouds

For the last five years, a spacecraft named Juno has traveled across 1.8 billion miles (2.8 billion kilometers) to arrive at the planet Jupiter. It will be a historic arrival that culminates in a critical sequence of ...

The Blind Astronomer of Nova Scotia

Tim Doucette is legally blind, yet he sees the stars better than most people. A childhood diagnosis of congenital cataracts forced doctors to remove Doucette's lenses and widen his pupils. That left the amateur astron...

Why every picture of a black hole is an illustration – Vox

No one has ever seen a black hole. There have been illustrations and computer simulations, but not even astronomers have seen a black hole... yet. In the spring of 2017, we might see... something. As a part of...
