NASA Spacecraft Nabs Stunning View of Comet Atlas Streaking Past the Sun

This guide provides a practical overview of NASA Spacecraft Nabs Stunning View of Comet Atlas Streaking Past the Sun, including its main features, benefits, limitations, and important considerations.

On Wednesday, Karl Battams, an astrophysicist at the Naval Research Laboratory, posted a magnificent short video of Atlas on its way through the solar system. Battams lead the Sungrazer Project, which uses images from solar telescopes maintained by NASA and the European Space Agency to look for moving objects around our star.

Battam's processed animation uses a series of images from NASA's Stereo-A spacecraft, a space-based observatory studying the sun, from May 30. Against a backdrop of stars, Atlas moves through the image on its journey through the solar system.

Atlas isn't the only interesting phenomenon appearing in the animation. Because the footage is captured by Stereo-A's heliospheric imagers, which are able to detect the solar wind, ghostly wisps of the stellar outflows are visible.

Another bonus? The planet Mercury, which sneaks into view from the upper-left quadrant as the animation continues. As Battams notes in his tweet, Mercury "has a tail," a trail of gas caused by the solar winds that pass over the planet. Mercury recently reached perihelion -- the point in its orbit closest to the sun -- when it was around 29 million miles from the star.

Atlas' closest approach to the sun was scheduled for May 31. Battams noted in a subsequent tweet he hopes to update the animation with further data in the coming days. Some astronomers have suggested Atlas could even disintegrate into "a haze of dust and gas" on closest approach.

The European Space Agency's Solar Orbiter, which launched in February to study the sun, passed through the comet's ion tail between May 31 and June 1 and is expected to pass through its dust tail on June 6 -- giving astronomers a rare chance to study the space rock in greater detail.
