The SEXTANT experiment successfully demonstrated autonomous space navigation using X-ray signals from pulsars, overcoming limitations of ground-based communication for deep space missions. Utilizing ...

Since the 1990s, humanity has discovered some truly bizarre exoplanets. Very hot, very big, orbiting multiple stars, or at a ...

A little bit of “scruff” in scientific data 50 years ago led to the discovery of pulsars — rapidly spinning dense stellar corpses that appear to pulse at Earth. Astronomer Jocelyn Bell made the chance ...

What types of exoplanets orbit pulsars? This is what a recent study published in The Astrophysical Journal Letters hopes to ...

NASA may have just improved our potential for deep space exploration by inventing a new type of autonomous space navigation. Known as Station Explorer for X-Ray Timing and Navigation Technology, or ...

This summer NASA launched its first-ever mission to gaze deep into the mysterious, rhythmically flickering entities called pulsars. The Neutron Star Interior Composition Explorer mission, or NICER, ...

As scientists know only too well, nature often delivers a scruffier, more inconvenient version of reality than the one they wished for. But there are rare occasions when the Universe presents a real ...

Scientists have detected an odd feature in the X-ray emissions coming from a pulsar, a find that could shed light on the composition of these amazingly dense, fast-spinning stars, a new study reports.
