BLACK HOLES

Introduction

How can we study these intriguing regions of space?

Black holes are among the most mysterious and fascinating features of the universe, piquing the interest of scientists since the 18th century, including Albert Einstein and Stephen Hawking. Astronomers have studied black holes across the entire electromagnetic spectrum by using both ground- and space-based telescopes. NASA’s fleet of astrophysics missions — including the Chandra Space Telescope, Hubble Space TelescopeSpitzer Space Telescope and Webb Space Telescope, — has helped scientists learn more about these captivating objects in space.

Activities

Sonifications

Experience black holes with audio as well!  Sonification is the process that translates data into sound.

Science Briefings

Science Briefings are professional learning telecons for the informal science education community, done in partnership with the NASA’s Museum & Informal Education Alliance. These monthly thematic briefings highlight current NASA astrophysics explorations and discoveries from across the suite of NASA astrophysics missions.

Teachable Moments

Teachable Moments harness data from the latest space missions and discoveries from NASA missions to answer the age-old question, “When are we ever going to use this?” Explore how we’re helping educators inspire the space explorers of the future.

Dissecting Supermassive Black Holes

Walk through the full process to learn how supermassive black holes convert fuel to produce bipolar jets, discover when star formation starts and stops, and examine a diagram of the processes at work.

A large-scale infographic, “Dissecting Supermassive Black Holes”; is dominated by a spiral galaxy and its jets on the left-hand side. An introduction follows. At right there are three sections with inset images and supporting text that details: (1) what is happening at the center of the galaxy, (2) what is happening where two jets are launched by its central, active supermassive black hole, and (3) what is happening in regions of star formation in the galaxy. The bottom section, separated by a line, illustrates and captions the feedback loop.
