Astronomers have discovered a pulsar that comes with its own magnifying glass — courtesy of its brown dwarf companion that’s being torn to shreds.
A unique pair of pulsars is inspiring new models for neutron-star magnetospheres.
Something funny is going on within a few hundred light-years of us, creating high-energy electrons that we don't understand. Recent data from NASA’s Fermi Gamma-ray Space Telescope keep the mystery alive.
Imagine a three-star system with two white dwarfs and a wildly spinning, superdense neutron star, all packed within a space no bigger than Earth's orbit.
NASA's Fermi Space Telescope recently spotted a pulsar in a rare transitional phase as it devours the matter of its companion star.
What spins hundreds of times per second, has 100 trillion times the Sun's density, and spews lethal radiation all over interstellar space? Astronomers are closer to knowing the answers, thanks to NASA's newest deep-space observatory.
A three-hour long burst on a neutron star has confirmed many long-suspected fact about the dense, spinning stars.
The Fermi Gamma-ray Space Telescope has made its first major discovery.
A pulsar discovered last April is helping astronomers measure the magnetic field surrounding our galaxy’s central black hole.
A few whirling neutron stars might get their start as very different objects, at least if a new analysis is correct.
A recent experiment to better understand the nature of dark matter constrains a possible "fifth force" of nature to almost zero.
Astronomers have discovered a neutron star that switches between X-ray and radio emission within a few days. The find is fabulous news for theorists, who have long predicted that the two pulsar types were connected.
Astronomers are looking forward to 2018, when a young pulsar will pass through its binary star companion’s disk.
New X-ray and radio observations detected a strange switcheroo in the radiation from a pulsar. The repeated hiccups have left scientists scratching their heads.
The Fermi Gamma-ray Space Telescope has discovered that almost all of the highest energy photons in the Large Magellanic Cloud come from two pulsars.
New pulsar picks-up first place as the fastest spinning object yet.
Pulsars flash in radio, but some of them flash a lot more powerfully in gamma rays, due to different processes happening in different places around them.
New images of two pulsars show beautiful, complex clouds of charged particles that illustrate the power dynamics in and around these spinning neutron stars.
