This is the first map of radioactivity in a supernova remnant, the blown-out bits and pieces of a massive star that exploded. The blue color shows radioactive material mapped in high-energy X-rays using NuSTAR. Heated, non-radioactive elements previously imaged by Chandra using low-energy X-rays are shown in red, yellow, and green. Image Credit/Caption: NASA/JPL-Caltech/CXC/SAO
An extraordinary jet trailing behind a runaway pulsar is seen in this composite image that contains data from Chandra (purple), radio data from the ACTA (green), and optical data from the 2MASS survey (red, green, and blue). The pulsar—a spinning neutron star—and its tail are found in the lower right of this image. The [...]
One of the first images taken by the Gaia space telescope during the commissioning phase of its mission, showing the star α Aquarii, also known as Sadalmelik, in the constellation of Aquarius. Image Credit: ESA/Airbus DS
Originally perceived by astronomers as a space mission that was unlikely to ever happen, the European Space Agency’s [...]
The European Space Agency’s PLATO mission aims to discover and characterize hundreds of Earth-sized exoplanets inside the habitable zones of approximately 1 million stars. The mission is likely to be approved for implementation by ESA during an announcement due for next week. Image Credit: PLATO Definition Study Report/ESA

Artist’s impression of an exoplanet with a mass approximately 3.6 times that of Earth, discovered orbiting just inside of the habitable zone of the Sun-like star HD 85512. Are “Super-Earths” such as this the most promising candidates for harboring extraterrestrial life? Image Credit: ESO/M. Kornmesser
“For there is a single general space, a single [...]
An image of quasar UM 287 (at center), taken by the Keck I telescope on the Keck Observatory in Hawaii. The cyan-colored glowing nebula seen around the quasar imaged for the first time is believed to be part of the cosmic web of filaments that interconnects all galaxies throughout the Universe.

A false-color photograph of Uranus, its rings, and 10 of its moons, taken by the Hubble Space Telescope’s Near Infrared Camera and Multi-Object Spectrometer in near-infrared wavelengths. As seen in this photo, there’s so much more to see on Uranus than meets the eye. This enigmatic world deserves a dedicated space mission to be [...]
A team of astronomers using ESA’s Herschel Space Observatory have discovered clear signals of water vapour coming off Ceres. Image Credit: ESA/ATG medialab/Küppers et al.
A new study published online in the weekly scientific journal Nature on Jan. 22 reports on observations made by the Herschel Space Observatory of water vapour seen coming out [...]
A long-exposure image of galaxy cluster Abell 2744, obtained by the Hubble Space Telescope, as part of the Hubble Frontier Fields program. The long blue streaks surrounding the cluster in the image come from the light of much more distant galaxies, located as far as 13 billion light-years away behind the cluster. Image Credit: [...]
