Gravitational waves ‘kicked’ a newborn black hole across space
Two black holes merged into one, and then sped off at around 5 million kilometers (3.1 million miles) per hour.

We finally have an image of the black hole at the heart of our galaxy
New observations from the Event Horizon Telescope reveal the chaotic region around the Milky Way’s central black hole, Sagittarius A*, in extreme detail.

Analyze This: Some 5,000 planets orbit stars other than our sun
A new cache of confirmed exoplanet discoveries marks a milestone in planets found beyond our solar system.
- Environment
Night lights make even the seas bright
Light from coastal cities and offshore development may shine deep enough to disrupt tiny critters living dozens of meters (yards) below the surface.
- Physics
Scientists Say: Doppler effect
The Doppler effect is a perceived change in the frequency of light or sound waves due to the wave source moving relative to an observer.

The Alps’ Matterhorn shows how much even big mountains sway
Such mountain sway data can help planners map high-risk zones for peaks, bridges or any large structures.

Wild art? No, it’s a radio image of the heart of our Milky Way
Eyelash-like radio filaments accent the brightest feature in this image — a supermassive black hole.

Explainer: Telescopes see light — and sometimes ancient history
Different kinds of telescopes on Earth and in space help us to see all wavelengths of light. Some can even peer billions of years back in time.
