The Chandra X-Ray Observatory, NASA’s space telescope which observes the universe using X-rays, has now completed its 15th year of operations, and astronomers are celebrating the anniversary with a series of special images from the orbiting observatory.
A view of the entire gamma-ray sky from the Fermi Space Telescope, shaded to emphasize the center of the Milky Way. The inset is a map of the galactic center with known sources removed, which reveals the gamma-ray excess (red, green, and blue) found there. This excess emission is consistent with annihilations from some [...]
An image of galaxy cluster 1E 0657-56, also known as the Bullet Cluster. It is a composite image made from observations in visible light from the Hubble Telescope and the Magellan ground-based Telescopes (the main cluster image) and in x-ray wavelengths from the Chandra Space Observatory (pink areas). Additional studies of gravitational lensing from [...]
Our latest view of the Universe and its history obtained by the ESA Planck space probe. Image Credit: ESA/Planck Collaboration/PA.
Recent findings from the European Space Agency’s Planck spacecraft have provided some minor revisions to the currently accepted parameters of the universe. As well as it now being 13.8 billion years old, the distribution [...]
The International Space Station is a sprawling complex the size of a football field. However, after decades of designs, redesigns, and being placed in a less-than-optimal orbit, is the complex worth the $100 billion price tag? Image Credit: NASA
For a long time, it looked as if it would never happen: the Reagan-era Space [...]

NASA held a news conference to detail the first findings of the Alpha Magnetic Spectrometer 2 (AMS-2) that was delivered to the [...]
This map shows the oldest light in our universe, as detected with the greatest precision yet by the Planck mission. The ancient light, called the cosmic microwave background, was imprinted on the sky when the universe was 370,000 years old. It shows tiny temperature fluctuations that correspond to regions of slightly different densities, representing [...]
NASA's Hubble Space Telescope has spotted what appears to be a clump of dark matter in an area known as Abell 520 – a huge merging cluster of galaxies some 2.4 billion light years away.
