            "description": "Observations of the Cassiopeia A supernova remnant by the Resolve instrument aboard the NASA-JAXA XRISM (X-ray Imaging and Spectroscopy Mission) spacecraft revealed strong evidence for potassium (green squares) in the southeast and northern parts of the remnant. Grids superposed on a multiwavelength image of the remnant represent the fields of view of two Resolve measurements made in December 2023. Each square represents one pixel of Resolve’s detector. Weaker evidence of potassium (yellow squares) in the west suggests that the original star may have had underlying asymmetries before it exploded.

Schmidt and K. ArcandAlt text: The Cassiopeia A supernova remnant with the XRISM Resolve fields of viewImage description: Supernova remnant Cassiopeia A appears as a large circular object outlined by electric blue filaments, set against a black background. Strings of vibrant colors weave throughout, with blue representing Chandra data, red, green, and blue representing Webb data, and Hubble data showing a multitude of stars that dot the view. Two nearly square grids are laid on top of the remnant slightly overlapping. The upper grid has six squares filled yellow, representing weaker evidence for potassium. In the opposite corner of that grid, five squares are filled green, representing a positive potassium detection. The lower grid has six boxes filled green in a wide M-like shape. The image is labeled “North” at the top center, “West” on the right, and “Southeast” to the left. || cas_a_with_resolve_1.png (800x645) [96.7 KB] || cas_a_with_resolve_1_print.jpg (1024x825) [125.5 KB] || cas_a_with_resolve_1_searchweb.png (320x180) [120.5 KB] || cas_a_with_resolve_1_web.png (320x258) [161.2 KB] || cas_a_with_resolve_1_thm.png (80x40) [7.6 KB] || ",

            "description": "For the first time astronomers have combined data from NASA’s Chandra X-ray Observatory and James Webb Space Telescope to study the well-known supernova remnant Cassiopeia A (Cas A). This work has helped explain an unusual structure in the debris from the destroyed star called the “Green Monster”, first discovered in Webb data in April 2023. The research has also uncovered new details about the explosion that created Cas A about 340 years ago, from Earth’s perspective.A new composite image contains X-rays from Chandra (blue), infrared data from Webb (red, green, blue), and optical data from Hubble (red and white). The outer parts of the image also include infrared data from NASA’s Spitzer Space Telescope (red, green and blue). The outline of the Green Monster can be seen by mousing over the image in the original feature, located here: chandra.cfa.harvard.edu/photo/2024/casa/.The Chandra data reveals hot gas, mostly from supernova debris from the destroyed star, including elements like silicon and iron. In the outer parts of Cas A the expanding blast wave is striking surrounding gas that was ejected by the star before the explosion. The X-rays are produced by energetic electrons spiraling around magnetic field lines in the blast wave. These electrons light up as thin arcs in the outer regions of Cas A, and in parts of the interior. Webb highlights infrared emission from dust that is warmed up because it is embedded in the hot gas seen by Chandra, and from much cooler supernova debris. The Hubble data shows stars in the field.Detailed analysis by the researchers found that filaments in the outer part of Cas A, from the blast wave, closely matched the X-ray properties of the Green Monster, including less iron and silicon than in the supernova debris. This interpretation is apparent from the color Chandra image, which shows that the colors inside the Green Monster’s outline best match with the colors of the blast wave rather than the debris with iron and silicon. The authors conclude that the Green Monster was created by a blast wave from the exploded star slamming into material surrounding it, supporting earlier suggestions from the Webb data alone.The debris from the explosion is seen by Chandra because it is heated to tens of millions of degrees by shock waves, akin to sonic booms from a supersonic plane. Webb can see some material that has not been affected by shock waves, what can be called “pristine” debris.Read more here: chandra.cfa.harvard.edu/photo/2024/casa/. || 53453268481_e80cfca2d4_o.jpg (4200x3386) [7.1 MB] || 53453268481_e80cfca2d4_o_searchweb.png (320x180) [121.1 KB] || 53453268481_e80cfca2d4_o_thm.png (80x40) [15.9 KB] || webb-chandra-hubble-and-spitzer-all-explore-cassiopeia-a-composite-all-4.hwshow || ",

Left: The galaxy’s central jets appear as they would if we viewed them both at the same angle. The black hole, embedded in a disk of dust and gas, launches a pair of particle jets traveling at nearly the speed of light. Scientists think gamma rays (magenta) detected by NASA’s Fermi Gamma-ray Space Telescope originate from the base of these jets. As the jets collide with material surrounding the galaxy, they form identical lobes seen at radio wavelengths (orange). The jets experienced two distinct bouts of activity, which created the gap between the lobes and the black hole. Right: The galaxy appears in its actual orientation, with its jets tipped out of our line of sight by about 50 degrees.Credit: NASA’s Goddard Space Flight Center || TXS0128_Side-by-Side_FInal.jpg (7680x2160) [1.8 MB] || TXS0128_Side-by-Side_FInal_Half.jpg (3840x1080) [601.5 KB] || TXS0128_Side-by-Side_FInal_print.jpg (1024x288) [45.4 KB] || TXS0128_Side-by-Side_FInal.jpg.dzi (7680x2160) [178 bytes] || TXS0128_Side-by-Side_FInal.jpg_files (1x1) [4.0 KB] || ",

The simulation shows the gravitational disturbance resulting from the distant flyby of a galaxy cluster about a tenth the mass of the Perseus cluster. The event causes cooler gas at the heart of the Perseus cluster to form a vast expanding spiral, which ultimately forms giant waves lasting hundreds of millions of years at its periphery.

How supernovas explode, however, has been a mystery for a long time. With the help of NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), scientists have been able to see into the heart of a supernova explosion for the first time, by detecting high-energy X-rays emitted by the radioactive isotope titanium-44. This image of Cas A shows titanium concentrated in clumps at the remnant's center (in blue). The irregular distribution of the clumps strongly suggests that material at the heart of the exploding star literally “sloshed” around, thereby allowing the shockwave to escape the core of the collapsing star and blast off the star’s outer layers. This NuSTAR map shows high-energy X-rays generated by titanium-44, shown here in blue. Lower-energy X-rays from non-radioactive material, imaged previously with NASA's Chandra X-ray Observatory, are shown in red, yellow and green. || ",

            "description": "The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors. Even though it is a small, or so-called dwarf galaxy, the SMC is so bright that it is visible to the unaided eye from the Southern Hemisphere and near the equator. Many navigators, including Ferdinand Magellan who lends his name to the SMC, used it to help find their way across the oceans. NASA's Chandra X-ray telescope has made the first detection of X-ray emission from young solar-type stars—stars with characteristics broadly similar to those of our sun—that lie outside our Milky Way galaxy. These stars live in a region known as the \"Wing\" of the SMC. This image of the Wing is a composite that combines data from three sources into one. X-ray data from Chandra are shown in purple; optical (i.e., visible) light seen by the Hubble Space Telescope is in red, green, and blue; and infrared data from the Spitzer Space Telescope are colored red. X-rays from young stars trace the activity and strength of stellar magnetic fields. Magnetic activity provides clues to a star's convection (the rising and falling of hot gas in the star's interior) and rotation rates. The combined X-ray, optical, and infrared data also reveal, for the first time outside our galaxy, objects that resemble very young, lowmass stars, which scientists call \"young stellar objects.\" These objects have ages of a few thousand years and are still embedded in the pillar of dust and gas from which stars form.Used in 2014 Calendar. || ",

            "description": "Shown here, observations from NASA's Chandra X-ray telescope reveal a massive cloud of multimillion-degree gas in a galaxy about 60 million light years from Earth. The hot gas cloud is likely caused by a collision between a dwarf galaxy [bottom left] and a much larger galaxy called NGC 1232 [center]. The image, which combines X-rays and optical light, shows the scene of the collision. Chandra X-ray data, in purple, show the hot gas has a comet-like appearance, caused by the motion of the dwarf galaxy. Optical data from the European Southern Observatory's Very Large Telescope reveal the spiral galaxy in blue and white. The X-ray emission source at the top right of the image appears to be unrelated to the galaxy collision. If confirmed, this discovery would mark the first time such a collision has been detected only in X-rays, and could have implications for understanding how galaxies grow through similar collisions. The impact between the dwarf galaxy and the spiral galaxy caused a shock wave—akin to a sonic boom on Earth—that generated the hot gas with a temperature of about 6 million degrees.Used in 2014 Calendar. || ",

            "description": "This composite image shows the galaxy cluster 1E 0657-56, also known as the \"bullet cluster.\" This cluster was formed after the collision of two large clusters of galaxies, the most energetic event known in the universe since the Big Bang. Hot gas detected by Chandra in X-rays is seen as two pink clumps in the image and contains most of the \"normal,\" or baryonic, matter in the two clusters. The bullet-shaped clump on the right is the hot gas from one cluster, which passed through the hot gas from the other larger cluster during the collision. An optical image from Magellan and the Hubble Space Telescope shows the galaxies in orange and white. The blue areas in this image show where astronomers find most of the mass in the clusters. The concentration of mass is determined using the effect of so-called gravitational lensing, where light from the distant objects is distorted by intervening matter. Most of the matter in the clusters (blue) is clearly separate from the normal matter (pink), giving direct evidence that nearly all of the matter in the clusters is dark. The animation below shows an artist's representation of the huge collision in the bullet cluster. Hot gas, containing most of the normal matter in the cluster, is shown in red and dark matter is in blue. During the collision the hot gas in each cluster is slowed and distorted by a drag force, similar to air resistance. In contrast, the dark matter is not slowed by the impact, because it does not interact directly with itself or the gas except through gravity, and separates from the normal matter. || ",

            "description": "Astronomers have recently completed a large survey—known as the Cosmic Evolution Survey, or COSMOS—of the sky using some of the powerful telescopes both on the ground and in space. Researchers wanted to test whether close encounters between two galaxies trigger activity in the supermassive blackholes at their centers. The two galaxies seen here are just samples from the thousands of galaxies studied. Chandra data were key because the X-rays could pinpoint just how active the black holes were. It turns out that the black holes within these galaxies are, in fact, growing more rapidly if they are in the early stages of an encounter with another galaxy. || ",

The Chandra data provide evidence that the star, known as CoRoT-2a, is blasting the extremely close planet with powerful X-rays. These X-rays are a hundred thousand times more intense than those that the Earth receives from the Sun. Astronomers estimate that this high-energy radiation is evaporating about 5 million tons of matter every second from the planet. Luckily, Earth is not in this same situation. || ",

Today, astronomers are confident the Cygnus X-1 system contains a black hole. In fact, a team of scientists have combined data from radio, optical, and X-ray telescopes including data from Chandra to determine the black hole's spin, mass, and distance more precisely than ever before. With these key pieces of information, the history of the black hole has been reconstructed. This new information gives astronomers strong clues about how the black hole was born, how much it weighed, and how fast it was spinning. || ",

The image of the remnant is a combination of X-ray data from Chandra and infrared data from the Two-Micron All-Sky Survey. Astronomers have gathered evidence to show that this remnant is the aftermath of what is called a Type 1A supernova. Type 1A supernovas happen when a white dwarf grows too massive and violently explodes. Astronomers want to understand the exact details of how Type 1A supernovas explode because they use them to measure the accelerated expansion of the universe and study dark energy. Because it is older than most Type 1A supernovas found so far, it provides astronomers with an excellent opportunity to study how these important objects evolve over time. || ",

Unfortunately, these stars aren’t understood very well because they are usually found relatively far away in places where lots of gas and dust impede our view. This star cluster (NGC 281) however, is an exception since it is far enough away from the plane of our galaxy  that not a lot of dust and gas obscure its view. The high-mass stars have powerful winds flowing from their surfaces and intense radiation that heats surrounding gas, boiling it away into interstellar space. This process results in the formation of the large columns of gas and dust seen on the left side of the image. These structures likely contain newly forming stars. The eventual deaths of massive stars as supernovas will also seed the galaxy with material and energy. Here we see NGC 281 in X-rays from Chandra and infrared data from Spitzer. || ",

By the 1960s, scientists had determined that the mysterious object was, in fact, a supernova. Later, they figured out that this supernova remnant, now known as RCW 86, was located about 8,000 light years away. Today, astronomers have taken data from four different telescopes to make this stunning new image. Here, X-rays from Chandra and XMM-Newton have been combined with infrared data from the Spitzer Space Telescope and the WISE mission. These data show that the explosion from nearly 2,000 years ago was caused by a so-called Type 1A supernova. This type of supernova happens when a white dwarf star pulls too much material from a companion star, causing a thermonuclear explosion to go off. || ",

Scientists have used virtually every telescope to study the Crab. The supernova left behind a magnetized neutron star â a pulsar. The pulsar spins 30 times a second. Each rotation sweeps a lighthouse-like beam, creating a pulse of electromagnetic energy detectable across the spectrum. Recently, NASA's Fermi Gamma Ray Observatory and Italy's AGILE Satellite detected strong gamma-ray flares from the Crab, including a series of \"superflares\" in April 2011. To help pinpoint the location of these flares, astronomers enlisted NASA's Chandra X-ray Observatory. With its keen X-ray eyes, Chandra saw lots of activity, but none seemed to correlated with the superflare. This hints that whatever is causing the flares is happening about a third of a light year from the pulsar. Chandra observations will likely help scientists explain gamma-ray flares. || ",

            "description": "This image from NASA’s Chandra X-Ray Observatory of Tycho's supernova remnant, dubbed Tycho for short, contains striking new evidence for what triggered the original supernova explosion, as seen from Earth in 1572. Tycho was formed by a Type Ia supernova, a category of stellar explosion used in measuring astronomical distances because of their reliable brightness.Low and medium energy X-rays in red and green show expanding debris from the supernova explosion. High energy X-rays in blue reveal the blast wave, a shell of extremely energetic electrons. Also shown in the lower left region of Tycho is a blue arc of X-ray emission. Several lines of evidence support the conclusion that this arc is due to a shock wave created when a white dwarf exploded and blew material off the surface of a nearby companion star. Previously, studies with optical telescopes have revealed a star within the remnant that is moving much more quickly than its neighbors, hinting that it could be the companion to the supernova that was given a kick by the explosion. || ",
