A new catalog produced by a French-led international team of astronomers shows that NASA’s Fermi Gamma-ray Space Telescope has discovered 294 gamma-ray-emitting pulsars, while another 34 suspects await confirmation. This is 27 times the number known before the mission launched in 2008.

Finding and studying Earth-like planets orbiting nearby stars is critical to understand whether we are alone in the universe. To study such planets and assess if they can sustain life, it is necessary to directly image them. However, these planets are difficult to observe, since light from the host star hides them with its glare.

NASA’s Hubble Space Telescope has measured the size of the nearest Earth-sized exoplanet that passes across the face of a neighboring star. This alignment, called a transit, opens the door to follow-on studies to see what kind of atmosphere, if any, the rocky world might have. The diminutive planet, LTT 1445Ac, was first discovered by […]

A system of seven sweltering planets has been revealed by continued study of data from NASA’s retired Kepler space telescope: Each one is bathed in more radiant heat from their host star per area than any planet in our solar system. Also unlike any of our immediate neighbors, all seven planets in this system, named […]

In 1895, Wilhelm Röntgen discovered X-rays and used them to image the bones in his wife’s hand, kicking off a revolutionary diagnostic tool for medicine. Now two of NASA’s X-ray space telescopes have combined their imaging powers to unveil the magnetic field “bones” of a remarkable hand-shaped structure in space.
