NASA’s space-based Chandra X-ray Observatory has watched a “clutter” of spider pulsars devouring their companion stars in the globular cluster Omega Centauri. This data could help scientists better understand how such rapidly spinning neutron stars, named after the arachnids that devour their mates, erode surrounding stars with intense beams of radiation. The five spider pulsars …
To survive in this Universe, you must avoid pulsars. An illustrated view of a black widow pulsar and its stellar companion. The pulsar’s gamma-ray emissions (magenta) strongly heat the facing side of the star (orange). The pulsar is gradually evaporating its partner.

Three extremely rare white lion cubs were born at the Las Delicias Zoo in Venezuela. This week in our wrap up, we lull you into a false sense of security with adorable lion cubs then ambush you with terrifying pulsars. We do this not out of a sense of malice but to prepare your mind …

The Fermi gamma-ray space telescope has discovered around 300 rapidly spinning neutron stars. Each of the newfound objects sweep two beams of radiation across the universe like a cosmic lighthouse. These neutron stars are known to spin hundreds of times per second and are specifically called millisecond pulsars; prior to the launch of Fermi in …

This visualization shows 294 gamma-ray pulsars, first plotted on an image of the entire starry sky as seen from Earth and then transitioning to a view from above our galaxy. The symbols show different types of pulsars. Young pulsars blink in real time except for the Crab, which pulses slower than in real time because …
In 1987, humanity observed the closest supernova since 1604. In 1604, the last naked-eye supernova to occur in the Milky Way galaxy happened, known today as Kepler’s supernova. Although the supernova faded from naked-eye view by 1605, its remnant remains visible today, as shown here in an X-ray/optical/infrared composite. The bright yellow “streaks” are the …
