Researchers at Cornell University are taking a new approach to the search for alien life: looking for habitable planets older than Earth, […]

Hubble and Chandra Unveil Mysteries Concerning Dark Matter

From HubbleSite: “This collage shows images of six different galaxy clusters taken with NASA’s Hubble Space Telescope and Chandra X-ray Observatory. The clusters were observed in a study of how dark matter in clusters of galaxies behaves when the clusters collide. Seventy-two large cluster collisions were studied in total. Using visible-light images from Hubble, […]

GODDARD SPACE FLIGHT CENTER, MD — The James Webb Space Telescope (JWST) is NASA’s top priority science mission launching in this decade and will have the capability to “look back towards the very first objects that formed after the Big Bang,” said Dr. John […]

European Space Agency Selects PLATO Observatory for Proposed 2024 Launch

From the European Space Agency (ESA): “The PLAnetary Transits and Oscillations of stars (PLATO) mission will identify and study thousands of exoplanetary systems, with an emphasis on discovering and characterising Earth-sized planets and super-Earths. It will also investigate seismic activity in stars, enabling a precise characterisation of the host sun of each planet discovered, […]

NuSTAR Sheds New Light on Supernova Explosions

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
