Zooming in on Pandora’s Cluster | Hubble

This sequence starts with a broad view of the southern skies. We close in on an apparently empty region of sky in the faint constellation of Sculptor. As we zoom in further we can start to make out a cloud of faint galaxies that is revealed in the final NASA/European Space Agency Hubble Space Telescope image to be a spectacularly rich merging cluster of galaxies called Abell 2744, and nicknamed Pandora's Cluster. This remarkable object seems to be the result of the collision of at least four separate galaxy clusters.

Hubble Space Telescope Sees "Ghost Light" from Dead Galaxies in Pandora's Cluster

Hubble Space Telescope Sees "Ghost Light" from Dead Galaxies in Pandora's Cluster

The massive galaxy cluster Abell 2744, nicknamed Pandora's Cluster, takes on a ghostly look in this NASA/European Space Agency Hubble Space Telescope view. Distance: 4 billion light years

In this image the total starlight from the cluster has been artificially colored blue. This reveals that not all the starlight is contained within the cities of stars—the galaxies—that appear as bright blue-white blobs. A fraction of the starlight is also dispersed throughout the cluster, as seen in the darker blue regions.

This light comes from dead galaxies. The galaxies were torn apart long ago by the cluster's gravitational forces, and their stars were scattered into what is known as intracluster space—the space between the galaxies.

These orphaned stars roam the cluster, without being gravitationally tethered to any single galaxy. Because these extremely faint stars are brightest at near-infrared wavelengths of light, this type of observation could only be accomplished with Hubble’s infrared sensitivity to extraordinarily dim light.

The galaxies that are not colored blue are either in the foreground or background and are not part of the cluster.

Dark Matter & Galaxies in Pandora's Cluster | NASA Optical & X-ray Views

Dark Matter & Galaxies in Pandora's Cluster | NASA Optical & X-ray Views

This image combines visible light exposures of galaxy cluster Abell 2744 taken by the NASA/European Space Agency Hubble Space Telescope and the European Southern Observatory’s Very Large Telescope (VLT), with X-ray data from NASA’s Chandra X-ray Observatory and a mathematical reconstruction of the location of dark matter.

The galaxies in the cluster, while they are the only part that is visible in the optical part of the spectrum, actually only provide around 5% of the mass in the cluster.

Hot intracluster gas (shown in pink, and responsible for around 20% of the mass in the cluster) is visible through its X-ray emissions, observed by NASA’s Chandra satellite.

The blue overlay shows a map of the mass in the cluster. This is reconstructed based on detailed analysis of the way that the cluster bends light from galaxies in the distant background. Evidence of this light bending can be seen in arc-like distortions in parts of this image. Since dark matter makes up the lion’s share of mass in the cluster—around 75%—this blue overlay reveals the location of the otherwise invisible dark matter.

Analysis of this data has allowed scientists to observe some strange phenomena in Abell 2744, including a pocket of dark matter with no gas or galaxies, and a clump of galaxies with no associated gas. Astronomers believe that Abell 2744 formed from the simultaneous pile-up of at least four separate clusters.

The Center of Pandora’s Cluster: Abell 2744 in Sculptor | Hubble

This Hubble image, taken by the Advanced Camera for Surveys (ACS), shows the central part of merging galaxy cluster Abell 2744, nicknamed Pandora’s Cluster. This remarkable object seems to be the result of the collision of at least four separate galaxy clusters. This cluster is thought to have a very violent history, having formed from a cosmic pile-up of multiple galaxy clusters.

Abell 2744 is a giant galaxy cluster resulting from the simultaneous pile-up of at least four separate, smaller galaxy clusters that took place over a span of 350 million years, and is located approximately 4 billion light years from Earth. The galaxies in the cluster make up less than five percent of its mass. The gas (around 20 percent) is so hot that it shines only in X-rays. Dark matter makes up around 75 percent of the cluster's mass. This cluster also shows a radio halo along with several other Abell clusters. It has a strong central halo, along with an extended tail, which could either be relic radiation, or an extension of the central halo.

Performing Science on The Moon with Radioisotopes | NASA Apollo Missions

Apollo 12 Mission: NASA astronaut Alan Bean unloads Apollo Lunar Surface Experiments Package (ALSEP) Radioisotope Thermoelectric Generator (RTG) fuel element.

Astronaut Alan L. Bean, lunar module pilot, is photographed at quadrant II of the Lunar Module (LM) during the first Apollo 12 extravehicular activity (EVA) on the Moon. This picture was taken by astronaut Charles Conrad Jr., commander. Here, Bean is using a fuel transfer tool to remove the fuel element from the fuel cask mounted on the LM's descent stage. The fuel element was then placed in the RTG, the power source for the ALSEP that was deployed on the moon by the two astronauts. The RTG is next to Bean's right leg. While astronauts Conrad and Bean descended in the LM "Intrepid" to explore the Ocean of Storms region of the moon, astronaut Richard F. Gordon Jr., command module pilot, remained with the Command and Service Modules (CSM) "Yankee Clipper" in lunar orbit.

Image Date: 11-19-1969

Alan Bean has just offloaded Apollo 12 ALSEP package No. 2 from the Scientific Equipment (SEQ) Bay using a retractable boom, pulleys, and cables. Cooling fins on the RTG can be seen just to the right of Alan's right knee.

Apollo Radioactive Fuel Case: Cylindrical-shaped assembly with assorted wires and sockets mounted inside a metallic bar cradle. This artifact was transferred to the Smithsonian's National Air & Space Museum in 1974 from NASA's Johnson Space Center.

The Apollo Lunar Surface Experiments Package (ALSEP) was a set of experiments that were placed on the Moon by the Apollo astronauts. The ALSEP received electrical power from heat produced by a radioactive substance. The power generator is called an radioisotope thermal generator (RTG). The radioactive material used for fuel by the RTG was stored outside the Lunar Module, mounted in a casing prior to transfer to the RTG.

The LSEP contained a collection of geophysical instruments designed to continue to monitor the environment of each Apollo landing site for a period of at least a year after the astronauts had departed. Designed for a life of one year (Apollo 17 was for two), they ended up working for up to 8 years, the experiments permanently shut down by Mission Control on September 30, 1977. Due to the experimental nature of the first landing of Apollo 11, especially the mechanics of getting to the lunar surface and back, science took a lesser role, so Apollo 11 had a simpler version known as the Early Apollo Surface Experiments Package (EASEP), with only two experiments.

The ALSEP/EASEP packages were stowed in Scientific Equipment Bay (SEQ Bay)/Quad II during the flight from Earth. The height of the pallets was at the limit for easy manual deployment on level terrain. There were booms to help with off-loading, particularly if the Lunar Module was tilted in such a way that the Bay was higher than normal. Lanyards were used to release the packages and allow them to swing free and then be lowered by pulley to the surface. On Apollo 15, the LM tilt put the package in easy reach and the off-loading was done entirely by hand. The pulleys were removed for Apollo 17 since the crew felt they were not needed. The mission timelines show offloading as a coordinated activity and allowed 8 to 9 minutes for both crewmen.

Radioisotope Heater Units (RHUs): Pull-apart Animation | NASA Space Tech

This 3D animation shows the main components of a radioisotope heater unit, or RHU, that is used to provide heat for many NASA missions that explore the solar system.

RHUs have a rich history of use on NASA missions. They were first used with the science experiments that were left on the surface of the Moon in 1969 by the Apollo 11 astronauts. Later NASA missions have carried them to Jupiter, Saturn, and Mars. All told, the United States has flown 300 RHUs on 32 space missions.

RHUs are small devices that use the decay of plutonium-238 to provide heat to keep spacecraft components and systems warm so that the equipment can survive long enough in the cold space environment to complete its mission. This heat is transferred to spacecraft structures, systems, and instruments directly, without moving parts or intervening electronic components.

By using RHUs, the spacecraft designer can allocate scarce spacecraft electrical power to operate the spacecraft systems and instruments. RHUs also provide the added benefit of reducing potential interference (electromagnetic interference) with instruments or electronics that might be generated by electrical heating systems.

An RHU contains a Pu-238 fuel pellet about the size of a pencil eraser and outputs about 1 Watt of heat. (The entire RHU is about the size of a C-cell battery.) A number of missions employ just a few RHUs for extra heat, while others have dozens.

Radioisotope Heater Units (RHUs) | NASA Space Exploration Technology

One small, simple type of radioisotope power system that is extremely versatile is known as a radioisotope heater unit, or RHU.

A single RHU passively radiates about one watt of heat. When placed carefully aboard a spacecraft or inside a rover, the heat energy from RHUs serves to keep a mission’s hardware at proper operating temperatures, compensating for the very cold temperatures often encountered in space exploration.
