\nIn the past century, humans have mastered how to detect light beyond what our eyes can see — unveiling secrets held in other parts of the electromagnetic spectrum. More recently, we have developed detectors for other signals from the universe — particles ejected from black holes and other high-energy sources and even wiggles of space-time in the form of gravitational waves. This new capability of combining information from all of these different messengers to more completely understand a source is called multimessenger astronomy.\n
\nThe four messengers astronomers study are light in all its forms, cosmic rays, neutrinos, and gravitational waves.\n
\nWhen an astronomical source varies slowly, astronomers can combine information from different messengers received at different times — sometimes even years apart — and still get a good picture of it. But many source types change rapidly with time. For them, it’s critical that observations occur simultaneously or within a short time span so that astronomers capture the properties of different messengers before the source changes. Astronomers call this “time domain” astronomy. Multimessenger time domain astronomy is a powerful new tool for exploring the cosmos.", "items": [], "extra_data": {} }, { "id": 371376, "url": "https://svs.gsfc.nasa.gov/gallery/multimessengerastronomy/#media_group_371376", "widget": "Card gallery", "title": "Going multimessenger", "caption": "", "description": "", "items": [ { "id": 411077, "type": "details_page", "extra_data": null, "instance": { "id": 13042, "url": "https://svs.gsfc.nasa.gov/13042/", "page_type": "Produced Video", "title": "NASA's Fermi Mission Shows How Luck Favors the Prepared", "description": "Explore how more than a century of scientific progress with gravitational waves, gamma rays and neutrinos has helped bring about the age of multimessenger astronomy.

The images bring astronomers a step closer to understanding the source of some of the universe's most energetic particles — cosmic rays. The emissions are likely the result of accelerated protons interacting with nearby gas clouds, but other possibilities have not been eliminated.

This discovery is a major step toward meeting one of Fermi's primary mission goals.Cosmic rays are subatomic particles that move through space at nearly the speed of light. About 90 percent of them are protons, with the remainder consisting of electrons and atomic nuclei. In their journey across the galaxy, the electrically charged particles become deflected by magnetic fields. This scrambles their paths and makes it impossible to trace their origins directly.Through a variety of mechanisms, these speedy particles can lead to the emission of gamma rays, the most powerful form of light and a signal that travels to us directly from its sources.Two supernova remnants, known as IC 443 and W44, are expanding into cold, dense clouds of interstellar gas. This material emits gamma rays when struck by high-speed particles escaping the remnants.Scientists have been unable to ascertain which particle is responsible for this emission because cosmic-ray protons and electrons give rise to gamma rays with similar energies. Now, after analyzing four years of data, Fermi scientists see a gamma-ray feature from both remnants that, like a fingerprint, proves the culprits are protons.When cosmic-ray protons smash into normal protons, they produce a short-lived particle called a neutral pion. The pion quickly decays into a pair of gamma rays. This emission falls within a specific band of energies associated with the rest mass of the neutral pion, and it declines steeply toward lower energies. Detecting this low-end cutoff is clear proof that the gamma rays arise from decaying pions formed by protons accelerated within the supernova remnants.In 1949, the Fermi telescope's namesake, physicist Enrico Fermi, suggested that the highest-energy cosmic rays were accelerated in the magnetic fields of interstellar gas clouds. In the decades that followed, astronomers showed that supernova remnants were the galaxy's best candidate sites for this process.?A charged particle trapped in a supernova remnant's magnetic field moves randomly throughout it and occasionally crosses through the explosion's leading shock wave. Each round trip through the shock ramps up the particle's speed by about 1 percent. After many crossings, the particle obtains enough energy to break free and escapes into the galaxy as a newborn cosmic ray. The Fermi discovery builds on a strong hint of neutral pion decay in W44 observed by the Italian Space Agency's AGILE gamma-ray observatory and published in late 2011.Watch this video on YouTube. || ", "release_date": "2013-02-14T14:00:00-05:00", "update_date": "2023-05-03T13:52:23.664601-04:00", "main_image": { "id": 468169, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a011200/a011209/Cas_A_Still.jpg", "filename": "Cas_A_Still.jpg", "media_type": "Image", "alt_text": "The husks of exploded stars produce some of the fastest particles in the cosmos.

The images bring astronomers a step closer to understanding the source of some of the universe's most energetic particles — cosmic rays. The emissions are likely the result of accelerated protons interacting with nearby gas clouds, but other possibilities have not been eliminated. Astrophysicists believe that supernova remnants are the galaxy's best candidate sites for cosmic-ray acceleration.

While astronomers have found indirect evidence of these disturbances, the waves have so far eluded direct detection. Ground-based observatories designed to find them are on the verge of achieving greater sensitivities, and many scientists think that this discovery is just a few years away. Catching gravitational waves from some of the strongest sources — colliding black holes with millions of times the sun's mass — will take a little longer. These waves undulate so slowly that they won't be detectable by ground-based facilities. Instead, scientists will need much larger space-based instruments, such as the proposed Laser Interferometer Space Antenna, which was endorsed as a high-priority future project by the astronomical community. A team that includes astrophysicists at NASA's Goddard Space Flight Center in Greenbelt, Md., is looking forward to that day by using computational models to explore the mergers of supersized black holes. Their most recent work investigates what kind of \"flash\" might be seen by telescopes when astronomers ultimately find gravitational signals from such an event. To explore the problem, a team led by Bruno Giacomazzo at the University of Colorado, Boulder, and including Baker developed computer simulations that for the first time show what happens in the magnetized gas (also called a plasma) in the last stages of a black hole merger. In the turbulent environment near the merging black holes, the magnetic field intensifies as it becomes twisted and compressed. The team suggests that running the simulation for additional orbits would result in even greater amplification. The most interesting outcome of the magnetic simulation is the development of a funnel-like structure — a cleared-out zone that extends up out of the accretion disk near the merged black hole. The most important aspect of the study is the brightness of the merger's flash. The team finds that the magnetic model produces beamed emission that is some 10,000 times brighter than those seen in previous studies, which took the simplifying step of ignoring plasma effects in the merging disks. || ", "release_date": "2012-09-27T12:00:00-04:00", "update_date": "2023-05-03T13:52:44.526816-04:00", "main_image": { "id": 472847, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a011000/a011086/Black_Hole_merger_Still.png", "filename": "Black_Hole_merger_Still.png", "media_type": "Image", "alt_text": "Supercomputer models of merging black holes reveal properties that are crucial to understanding future detections of gravitational waves.
