They came from other stars! [COMIC]

Only three interstellar objects have ever been spotted. Here’s what we know about them and why they’re so cool.
Computer models show that a star's tug could send Mercury, Venus or Mars crashing into Earth — or let Jupiter eject our world from the solar system.
In an early reshuffling of the solar system, comet collisions and other space rocks could have sent dusty bits falling to Titan’s surface.
Astronomers have captured polarized light coming from the Milky Way’s supermassive black hole. This offers insight into its magnetic fields.
Nathaniel Frissell uses radio data to study how eclipses affect a layer of the atmosphere called the ionosphere.
A Chinese rover used radar to reveal long-buried terrain. The discovery hints that Mars’ equator was once much colder and wetter.
Scientists made a device that converts the greenhouse gas into formate. This salt can then run a fuel cell to make electricity.
Spotted in images from the James Webb telescope, the high-altitude current may help untangle the workings of the giant planet’s atmosphere.
Infrared light from a distant star appears to be leftovers of an impact between a pair of Neptune-sized worlds.
The sun will be near the peak of its activity cycle during the eclipse on April 8, 2024. That will make it a great time to crowdsource solar research.
