Webb reveals new structures within iconic supernova

NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987. New observations by Webb's NIRCam (Near-Infrared Camera) provide a crucial clue to our understanding of how a supernova develops over time to shape its remnant.

This image reveals a central structure like a keyhole. This center is packed with clumpy gas and dust ejected by the supernova explosion. The dust is so dense that even near-infrared light that Webb detects can't penetrate it, shaping the dark "hole" in the keyhole.

A bright, equatorial ring surrounds the inner keyhole, forming a band around the waist that connects two faint arms of hourglass-shaped outer rings. The equatorial ring, formed from material ejected tens of thousands of years before the supernova explosion, contains bright hot spots, which appeared as the supernova's shock wave hit the ring. Now spots are found even exterior to the ring, with diffuse emission surrounding it. These are the locations of supernova shocks hitting more exterior material.

While these structures have been observed to varying degrees by NASA's Hubble and Spitzer Space Telescopes and Chandra X-ray Observatory, the unparalleled sensitivity and spatial resolution of Webb revealed a new feature in this supernova remnant—small crescent-like structures.

These crescents are thought to be a part of the outer layers of gas shot out from the supernova explosion. Their brightness may be an indication of limb brightening, an optical phenomenon that results from viewing the expanding material in three dimensions. In other words, our viewing angle makes it appear that there is more material in these two crescents than there actually may be.

The high resolution of these images is also noteworthy. Before Webb, the now-retired Spitzer telescope observed this supernova in infrared throughout its entire lifespan, yielding key data about how its emissions evolved over time. However, it was never able to observe the supernova with such clarity and detail.

Despite the decades of study since the supernova's initial discovery, there are several mysteries that remain, particularly surrounding the neutron star that should have been formed in the aftermath of the supernova explosion. Like Spitzer, Webb will continue to observe the supernova over time.

Its NIRSpec (Near-Infrared Spectrograph) and MIRI (Mid-Infrared Instrument) instruments will offer astronomers the ability to capture new, high-fidelity infrared data over time and gain new insights into the newly identified crescent structures. Further, Webb will continue to collaborate with Hubble, Chandra, and other observatories to provide new insights into the past and future of this legendary supernova.

Behold NGC 2283, a barred spiral galaxy 45 million light-years away captured by James Webb Telescope

The James Webb Space Telescope has done it again! Today, NASA/ESA/CSA released Webb’s latest mesmerizing image—a breathtaking view of the barred spiral galaxy NGC 2283, located 45 million light-years away in the constellation Canis Major. This cosmic marvel, captured using Webb’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI), showcases the galaxy’s intricate structure, star-forming regions, and the life cycle of stars in dazzling detail.

A Glimpse into the Heart of NGC 2283

Barred spiral galaxies like NGC 2283 have a central bar of stars, acting as a cosmic highway that channels gas into the galaxy’s core, fueling star formation. Webb’s infrared eyes reveal the delicate interplay between stars, gas, and dust, bringing into focus the glowing knots of gas where new stars are being born. These dense pockets of hydrogen, ignited by stellar nurseries, illuminate the graceful spiral arms winding around the core.

The Power of Infrared Imaging

Webb observed NGC 2283 for 17 minutes, collecting data across six different infrared filters. These filters allow astronomers to peer through cosmic dust and uncover hidden details. The image reveals:

Brilliant star clusters scattered throughout the spiral arms

Polycyclic aromatic hydrocarbons (PAHs), sooty molecules that help astronomers trace cosmic chemistry

Interstellar gas clouds heated by young, massive stars

Foreground stars from our Milky Way, their diffraction spikes adding to the celestial display

A Galaxy Shaped by Stellar Explosions

NGC 2283 is no stranger to cosmic fireworks. Just over two years ago, astronomers witnessed a stellar explosion in this very galaxy. The supernova, SN 2023AXU, was a Type II supernova—the violent death of a massive star at least eight times the mass of our Sun. These spectacular explosions enrich the galaxy with elements like oxygen and sodium, seeding the next generation of stars and continuing the grand cosmic cycle.

Part of a Larger Cosmic Survey

This image is part of an ambitious Webb program (#3707) aimed at studying the intricate relationships between stars, gas, and dust in 55 nearby star-forming galaxies. By observing these galactic ecosystems, astronomers hope to unravel the mysteries of star formation and galaxy evolution, giving us deeper insights into our own Milky Way’s origins.

A Cosmic Time Machine

As we marvel at this new glimpse of NGC 2283, we are reminded that every light-year Webb’s gaze traverses is a journey back in time. This image captures NGC 2283 as it was 45 million years ago—when early primates roamed Earth and our planet was undergoing climatic shifts. Through Webb’s lens, we witness history written in the language of starlight.
