            "description": "This artist’s concept of the BP Crucis system follows the pulsar on a passage through the dense stream of plasma flowing from its companion, a blue hypergiant 40 times the Sun’s mass. During each four-day passage, the pulsar’s X-ray brightness flares as it pulls in some of the gas. At first, the gas forms a messy, turbulent accretion disk around the pulsar, and plasma spirals down to it. But as the pulsar moves deeper into the stream, there’s not enough angular momentum to support the disk, and it breaks up. At this point, plasma falls straight onto the pulsar. Later, as the pulsar nears the end of its passage, a messy accretion disk rebuilds, this time spinning in the opposite direction of the earlier disk. Credit: NASA’s Goddard Space Flight Center Conceptual Image LaboratoryAlt text: Animation of the BP Crucis system0:00 A wide view, showing the giant star, its gas stream, and the pulsar nearing it.  0:08 The camera zooms into the pulsar as it encounters the stream.  0:10 Gas flowing past the pulsar forms a clockwise-spinning accretion disk.  0:17 The disk breaks up.

The pulsar flares up in X-rays twice each orbit when it encounters the stream. Credit: NASA’s Goddard Space Flight Center Conceptual Image LaboratoryAlt text: Artist’s concept of BP CrucisImage description: Against a hazy, star-filled sky, a brilliant bluish-white star shines near the center of this artist’s concept. From the star, at about 4 o’clock, an expanding stream of bluish gas arcs toward lower left and then sweeps toward bottom center as it moves into the foreground. Another bright star-like point, much smaller, shines near the stream, just right of the image’s center. It emits two long, thin, wedge-shaped beams of radiation. One emerges at about 2 o’clock and heads to the upper right, the other, emerging at 7 o’clock, heads toward lower left. Text reads “Artist’s concept.”  ",
