SUNSET: 
Jupiter Has Trapped a Comet in a Bizarre Orbit
Jupiter has captured an icy comet from the outer solar system. The comet's bizarre orbit will bring it back for another super-close pass in 2063.
Ryugu May Have Skirted Close to the Sun
Observations by the Japanese Hayabusa 2 spacecraft show subtle color differences, indicating something has reddened the asteroid’s surface.
Weak Martian Magnetic Field May Have Let Air Out
Mars's magnetic field weakened and disappeared billions of years ago. Now, scientists have found that the weak field might have been worse than none at all.
How Lazy Is the Sun?
Astronomers studying hundreds of Sun-like stars were surprised to find that most of them are more active than the Sun. Why is the Sun different?

The first two interstellar visitors to the solar system are finally shedding light on their places of origin.
Is Earth's Minimoon Still Here?
Reports of the loss of Earth's minimoon may have been somewhat exaggerated — new research suggests the moonlet will leave Earth orbit in early may.
Is the Interstellar Comet 2I/Borisov Breaking Up?
New observations of the interstellar comet — which traveled unaltered for eons before arriving in the solar system — have revealed it's fragmenting
Why Have Parts of Mercury's Landscape "Deflated"?
