Interview with Astronomer Robert Kirshner

Hubble Captures Wide View of Supernova 1987A

This Hubble Space Telescope image shows Supernova 1987A within the Large Magellanic Cloud, a neighboring galaxy to our Milky Way. Distant stars serve as a backdrop for Supernova 1987A, located in the center of the image. The bright ring around the central region of the exploded...

Multiwavelength View of Supernova 1987A

Astronomers combined observations from three different observatories to produce this colorful, multiwavelength image of the intricate remains of Supernova 1987A. The red color shows newly formed dust in the center of the supernova remnant, taken at submillimeter wavelengths by...

An ALMA View of Supernova 1987A

This is an image of the intricate remains of Supernova 1987A taken in submillimeter wavelengths by the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile. The red color shows newly formed dust in the center of the supernova remnant. Image Credit: NASA, ESA,...

A Hubble View of Supernova 1987A

This is an image of the intricate remains of Supernova 1987A taken by NASA’s Hubble Space Telescope. The green hue reveals where the expanding shock wave from the exploded star is colliding with a ring of material around the supernova. The green represents the glow of visible...

A Chandra View of Supernova 1987A

This is an image of the intricate remains of Supernova 1987A taken by NASA’s Chandra X-ray Observatory. The blue hue reveals where the expanding shock wave from the exploded star is colliding with a ring of material around the supernova. The blue color reveals the hottest gas....

A Ring's Light Show

These images, taken between 1994 and 2016 by NASA's Hubble Space Telescope, chronicle the brightening of a ring of gas around an exploded star. The stellar blast, called Supernova 1987A, was first spotted 30 years ago. The explosion is the nearest supernova event in more than...

Scale and Compass for SN 1987A

Image of Supernova Remnant SN 1987A, with compass arrows, scale bar, and color key for reference. The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky (as seen from below) is flipped relative...

Hubble Chronicles Brightening of Ring around an Exploded Star (Annotated)

This time-lapse video sequence of Hubble Space Telescope images reveals dramatic changes in a ring of material around the exploded star Supernova 1987A. The images, taken from 1994 to 2016, show the effects of a shock wave from the supernova blast smashing into the ring. The...

The Development of Supernova 1987A

This scientific visualization shows the development of Supernova 1987A, from the initial blast observed three decades ago to the luminous ring of material we see today. The sequence, using data from a computer simulation, begins with the star before it exploded. A ring of...

A Zoom into Supernova 1987A

The video begins with a nighttime view of the Small and Large Magellanic clouds, satellite galaxies of our Milky Way. It then zooms into a rich star-birth region in the Large Magellanic Cloud. Nestled between mountains of red-colored gas is the odd-looking structure of Supernova...
