Supernova Remnant Video From NASA’s Chandra Is Decades in Making

A new video shows the evolution of Kepler’s Supernova Remnant using data from NASA’s Chandra X-ray Observatory captured over more than two and a half decades. Kepler’s Supernova Remnant, named after the German astronomer Johannes Kepler, was first spotted in the night sky in 1604. Today, astronomers know that a white dwarf star exploded when […]

Supernova Remnants

Adding Dimension to Cassiopeia A

Using NASA’s James Webb Space Telescope, astronomers uncovered a mysterious feature within the remnant, nicknamed the “Green Monster,” alongside a puzzling network of ejecta filaments forming a web of oxygen-rich material.

Seeing the Cygnus Loop in a New Way

The Cygnus Loop, also known as the Veil Nebula, is a supernova remnant – the remains of the explosive death of a massive star. Studying images like these leads to discovery, but NASA’s Chandra X-ray Observatory provides another way to experience this data: three-dimensional (3D) models that allow people to explore – and print – […]

NASA’s Chandra Releases New 3D Models of Cosmic Objects

New three-dimensional (3D) models of objects in space have been released by NASA’s Chandra X-ray Observatory. These 3D models allow people to explore — and print — examples of stars in the early and end stages of their lives. They also provide scientists with new avenues to investigate scientific questions and find insights about the […]
