Supernovas & Supernova Remnants

Visualizing Supernova 1987A in Three Dimensions

Our latest press release features work by Salvatore Orlando, an astrophysicist working at the INAF-Osservatorio Astronomico di Palermo in Italy. Salvatore and his colleagues have developed the first three-dimensional model of the famous object Supernova 1987A that links the supernova to its remnant, an accomplishment that will help scientists and the public explore this important stellar object like never before. We are very pleased to share answers that Salvatore has provided to our questions about his 3D modeling.

Salvatore graduated in physics from the University of Palermo and completed his PhD at the same university. During his PhD he spent part of this time at the Dept. of Astronomy and Astrophysics at the University of Chicago. Prior to his current position, he was a research fellow for two years at the European Space Agency (ESA), Space Science Dept. (Noordwijk, The Netherlands). His main research activity has been performed in the realm of optically thin astrophysical plasmas (more specifically solar and stellar coronae, supernova remnants) and in the field of thermal and non-thermal (synchrotron) emission processes.

Young Magnetar Likely the Slowest Pulsar Ever Detected

RCW 103
Using NASA's Chandra X-ray Observatory and other X-ray observatories, astronomers have found evidence for what is likely one of the most extreme pulsars, or rotating neutron stars, ever detected. The source exhibits properties of a highly magnetized neutron star, or magnetar, yet its deduced spin period is thousands of times longer than any pulsar ever observed.

Taking a Supernova into the Third Dimension

When a satellite such as NASA's Chandra X-ray Observatory observes an object in space, its camera records photons – packets of energy that make up electromagnetic radiation. Recordings of these packets of energy come down to Earth from the spacecraft via NASA’s Deep Space network coded in the form of 1's and 0's.

Chandra Movie Captures Expanding Debris From a Stellar Explosion

Tycho's Supernova Remnant
When the star that created this supernova remnant exploded in 1572, it was so bright that it was visible during the day. And though he wasn't the first or only person to observe this stellar spectacle, the Danish astronomer Tycho Brahe wrote a book about his extensive observations of the event, gaining the honor of it being named after him.

What Spawned the Jellyfish Nebula?

IC 443
The Jellyfish Nebula, also known by its official name IC 443, is the remnant of a supernova lying 5,000 light years from Earth. New Chandra observations show that the explosion that created the Jellyfish Nebula may have also formed a peculiar object located on the southern edge of the remnant, called CXOU J061705.3+222127, or J0617 for short. The object is likely a rapidly spinning neutron star, or pulsar.

Exploded Star Blooms Like a Cosmic Flower

Because the debris fields of exploded stars, known as supernova remnants, are very hot, energetic, and glow brightly in X-ray light, NASA's Chandra X-ray Observatory has proven to be a valuable tool in studying them. The supernova remnant called G299.2-2.9 (or G299 for short) is located within our Milky Way galaxy, but Chandra's new image of it is reminiscent of a beautiful flower here on Earth.

Supernova Shock Waves, Neutron Stars, and Lobsters

MSH 11-62 and G327.1-1.1*

A supernova that signals the death of a massive star sends titanic shock waves rumbling through interstellar space. An ultra-dense neutron star is usually left behind, which is far from dead, as it spews out a blizzard of high-energy particles. Two new images from NASA's Chandra X-ray Observatory provide fascinating views - including an enigmatic lobster-like feature - of the complex aftermath of a supernova.
