NASA's Fermi Proves Supernova Remnants Produce Cosmic Rays

The W44 supernova remnant is nestled within and interacting with the molecular cloud that formed its parent star. Fermi's LAT detects GeV gamma rays (magenta) produced when the gas is bombarded by cosmic rays, primarily protons. Radio observations (yellow) from the Karl G. Jansky Very Large Array near Socorro, N.M., and infrared (red) data from NASA's Spitzer Space Telescope reveal filamentary structures in the remnant's shell. Blue shows X-ray emission mapped by the Germany-led ROSAT mission.

View of Cosmic Ray Experiment near the Apollo 15 Lunar Module

AS16-107-17442 (22 April 1972) --- A close-up view of the Apollo 16 Cosmic Ray Detector (CRD) experiment deployed at the +Y strut of the Lunar Module (LM). The crewmembers moved it to this position from near the deployment site of the Apollo Lunar Surface Experiments Package (ALSEP) because, in the words of astronaut John W. Young, commander, "The panels were getting a little warm." Note that the LM did not skid upon landing, as evidenced by the landing contact probe's folded back (neatly) position and the lack of skid marks. While astronauts Young, and Charles M. Duke Jr., lunar module pilot; descended in the Apollo 16 Lunar Module (LM) "Orion" to explore the Descartes highlands landing site on the moon, astronaut Thomas K. Mattingly II, command module pilot, remained with the Command and Service Modules (CSM) "Casper" in lunar orbit.

Stars and Cosmic Rays Observed from Mars

In this five-minute exposure taken from the surface of Mars by NASA Spirit rover, stars appear as streaks due to the rotation of the planet, and instantaneous cosmic-ray hits appear as points of light. Spirit took the image with its panoramic camera on March 11, 2004, after waking up during the martian night for a communication session with NASA's Mars Global Surveyor orbiter. Other exposures were also taken. The images tested the capabilities of the rover for night-sky observations. Scientists will use the results to aid planning for possible future astronomical observations from Mars. The difference in Mars' rotation, compared to Earth's, gives the star trails in this image a different orientation than they would have in a comparable exposure taken from Earth. http://photojournal.jpl.nasa.gov/catalog/PIA05551

Spacelab

This STS-51F mission onboard Photograph shows some of the Spacelab-2 instruments in the cargo bay of the Orbiter Challenger. The Plasma Diagnostics Package (PDP). shown at the end of the Remote Manipulator System (RMS), used instruments on a subsatellite to study natural plasma processes, orbiter-induced plasma processes, and beam plasma physics. Fourteen instruments were mounted on the PDP for measurements of various plasma characteristics. The X-ray Telescope (XRT), is at the front. The goal of this investigation was to image and examine the X-ray emissions from clusters of galaxies in order to study the mechanisms that cause high-temperature emissions and to determine the weight of galactic clusters. The Small Helium-Cooled Infrared Telescope (IRT) is at the right behind the XRT. The objective of this investigation was to measure and map diffused and discrete infrared astronomical sources while evaluating the Space Shuttle as a platform for infrared astronomy. At the same time, a new large superfluid helium dewar system for cooling the telescope was evaluated. The egg-shaped Cosmic Ray Nuclei experiment (CRNE) is shown at the rear. This investigation was to study the composition of high-energy cosmic rays by using a large instrument exposed to space for a considerable period of time. Spacelab-2 (STS-51F, 19th Shuttle mission) was launched aboard the Space Shuttle Orbiter Challenger on July 29, 1985.

High Energy Astronomy Observatory (HEAO)

This Atlas/Centaur launch vehicle, carrying the High Energy Astronomy Observatory (HEAO)-3, lifted off on September 20, 1979. The HEAO-3's mission was to survey and map the celestial sphere for gamma-ray flux and make detailed measurements of cosmic-ray particles. It carried three scientific experiments: a gamma-ray spectrometer, a cosmic-ray isotope experiment, and a heavy cosmic-ray nuclei experiment. The HEAO-3 was originally identified as HEAO-C but the designation was changed once the spacecraft achieved orbit.

This global map of Mars, based on data from NASA Mars Odyssey, shows the estimated radiation dosages from cosmic rays reaching the surface, a serious health concern for any future human exploration of the planet.

Estimated Radiation Dosage on Mars

This image from NASA Curiosity Mars rover, taken on April 3, 2014, includes a bright spot near the upper left corner. Possible explanations include a glint from a rock or a cosmic-ray hit.

Voyager 2: Hello Interstellar Space, Goodbye Heliosphere

At the end of 2018, the cosmic ray subsystem (CRS) aboard NASA's Voyager 2 spacecraft provided evidence that Voyager 2 had left the heliosphere (the plasma bubble the Sun blows around itself). There were steep drops in the rate at which particles that originate inside the heliosphere hit the instrument's radiation detector. At the same time, there were significant increases in the rate at which particles that originate outside our heliosphere (also known as galactic cosmic rays) hit the detector. The graphs show data from Voyager 2's CRS, which averages the number of particle hits over a six-hour block of time. CRS detects both lower-energy particles that originate inside the heliosphere (greater than 0.5 MeV) and higher-energy particles that originate farther out in the galaxy (greater than 70 MeV). https://photojournal.jpl.nasa.gov/catalog/PIA22924

GeV-gamma-ray emission regions

NASA's Fermi Closes on Source of Cosmic Rays New images from NASA's Fermi Gamma-ray Space Telescope show where supernova remnants emit radiation a billion times more energetic than visible light. The images bring astronomers a step closer to understanding the source of some of the universe's most energetic particles -- cosmic rays. Fermi mapped GeV-gamma-ray emission regions (magenta) in the W44 supernova remnant. The features clearly align with filaments detectable in other wavelengths. This composite merges X-rays (blue) from the Germany-led ROSAT mission, infrared (red) from NASA's Spitzer Space Telescope, and radio (orange) from the Very Large Array near Socorro, N.M.

The Changing X-ray Brightness of SS 433 (Illustration)

This illustration shows the object known as SS 433, located in the Milky Way galaxy and only about 20,000 light-years from Earth. Researchers think SS 433 is an ultraluminous X-ray source, or ULX, a compact cosmic object that must have an X-ray luminosity that is about a million times the total luminosity output of the Sun (at all wavelengths). ULXs are so bright, they can be seen millions of light-years away, in other galaxies. SS 433 appears to be about 1,000 times dimmer than the minimum threshold to be considered a ULX. This faintness is likely a trick of perspective: The high-energy X-rays from SS 433 are initially confined within two cones of gas extending outward from opposite sides of the central object. These cones are similar to a mirrored bowl that surrounds a flashlight bulb: They corral the X-ray light from SS 433 into a narrow beam, until it escapes and is detected by NuSTAR. But because the cones are not pointing directly at Earth, NuSTAR can't see the object's full brightness. Animation available at https://photojournal.jpl.nasa.gov/catalog/PIA24574

Voyager 2 CRS Data

These graphs compare data from identical instruments onboard NASA's Voyager 1 and Voyager 2 spacecraft as they each exited the heliosphere. Voyager 1 exited in 2012, and Voyager 2 exited in 2018. The cosmic ray subsystem (CRS) measures the rate of energetic particles hitting the radiation detector on the instrument. The top graph shows high energy particles (called cosmic rays) that originate outside the heliosphere. The CRS instruments on both spacecraft observed similar, but not identical, increases in the cosmic ray rate as they both crossed the heliopause (the outer edge of the heliosphere). The lower graph shows slightly lower energy particles that originate inside the heliosphere. Both spacecraft detected a similar but not identical decrease in these lower energy particles when they crossed the heliopause and immediately after. https://photojournal.jpl.nasa.gov/catalog/PIA22916

Several Signs Pointing to Interstellar Space

This set of graphs illustrates how data from two key instruments point to NASA's Voyager 2 spacecraft entering interstellar space, or the space between the stars, in November 2018. The top two plots come from the plasma science experiment (PLS). The plasma -- or ionized gas -- of interstellar space is significantly denser than the plasma inside the bubble of plasma the Sun blows around itself (the heliosphere). There is a jump on the graph in November 2018. At the same time, the measurements show that the outward speed (radial velocity) of the plasma the Sun is blowing (also known as the solar wind) sharply decreased. The bottom two plots come from the cosmic ray subsystem, which counts hits per second of higher-energy particles that originate from outside the solar bubble and lower-energy particles that originate from inside the solar bubble. The outsideparticles (also known as galactic cosmic rays or GCRs) increased and the inside particles (greater than 0.5 MeV) decreased at the same time the plasma science instrument detected its changes. The horizontal axis proceeds according to the numbered days of the year in 2018. https://photojournal.jpl.nasa.gov/catalog/PIA22923
