The Chandra Data Archive is a sophisticated digital system that ultimately contains all of the data obtained by the telescope since its launch into space in 1999. Chandra’s archive is a resource that makes these data available to the scientific community and the general public for years after they were originally obtained.
Each of these six new images also includes data from telescopes
covering other parts of the electromagnetic spectrum, such as visible
and infrared light. This collection of images represents just a small
fraction of the treasures that reside in Chandra’s unique X-ray archive.
From left to right, starting on the top row, the objects are:
Westerlund 2, 3C31, PSR J1509-5850, Abell 665, RX J0603.3+4214 and CTB 37A
Westerlund 2:
A cluster of young stars – about one to two million years old – located
about 20,000 light years from Earth. Data in visible light from the
Hubble Space Telescope (green and blue) reveal thick clouds where the
stars are forming. High-energy radiation in the form of X-rays, however,
can penetrate this cosmic haze, and are detected by Chandra (purple).
3C31:
X-rays from the radio galaxy 3C31 (blue), located 240 million light
years from Earth, allow astronomers to probe the density, temperature,
and pressure of this galaxy, long known to be a powerful emitter of
radio waves. The Chandra data also reveal a jet blasting away from one
side of the central galaxy, which also is known as NGC 383. Here, the
Chandra X-ray image has been combined with Hubble’s visible light data
(yellow).
PSR J1509-5850:
Pulsars were first discovered in 1967 and today astronomers know of
over a thousand such objects. The pulsar, PSR J1509-5850, located about
12,000 light years from Earth and appearing as the bright white spot in
the center of this image, has generated a long tail of X-ray emission
trailing behind it, as seen in the lower part of the image. This pulsar
has also generated an outflow of particles in approximately the opposite
direction. In this image, X-rays detected by Chandra (blue) and radio
emission (pink) have been overlaid on a visible light image from the
Digitized Sky Survey of the field of view.
Abell 665:
Merging galaxy clusters can generate enormous shock waves, similar to
cold fronts in weather on Earth. This system, known as Abell 665, has an
extremely powerful shockwave, second only to the famous Bullet Cluster.
Here, X-rays from Chandra (blue) show hot gas in the cluster. The bow
wave shape of the shock is shown by the large white region near the
center of the image. The Chandra image has been added to radio emission
(purple) and visible light data from the Sloan Digital Sky Survey
showing galaxies and stars (white).
RX J0603.3+4214:
The phenomenon of pareidolia is when people see familiar shapes in
images. This galaxy cluster has invoked the nickname of the “Toothbrush
Cluster” because of its resemblance to the dental tool. In fact, the
stem of the brush is due to radio waves (green) while the diffuse
emission where the toothpaste would go is produced by X-rays observed by
Chandra (purple). Visible light data from the Subaru telescope show
galaxies and stars (white) and a map from gravitational lensing (blue)
shows the concentration of the mass, which is mostly (about 80%) dark
matter.
CTB 37A:
Astronomers estimate that a supernova explosion should occur about
every 50 years on average in the Milky Way galaxy. The object known as
CTB 37A is a supernova remnant located in our Galaxy about 20,000 light
years from Earth. This image shows that the debris field glowing in
X-rays (blue) and radio waves (pink) may be expanding into a cooler
cloud of gas and dust seen in infrared light (orange).
