Active small bodies—including comets, active asteroids, icy minor planets, and transitional objects—occupy a unique position in planetary science. As ...

New observations show a small Saturn moon has generated electromagnetic waves that extend more than 313,000 miles behind it inside Saturn’s magnetic field. That newly measured reach reveals a tiny icy ...

Solar eclipses happen when the Moon passes between the Sun and Earth, casting a shadow on our planet. Depending on distance ...

Out in the Kuiper Belt, the massive doughnut of debris beyond Neptune, about one in 10 kilometer-scale objects have surprised ...

The shape of the cosmos depends on a balance of two competing forces: the pull of gravity and the expansion driven by dark ...

Gas giants possibly developed slowly in the solar system. They developed cores layer by layer within a disk of ice and dust ...

Scientists say a nearby red dwarf star hosts a planetary lineup that looks like a mirror image of our own solar system, with rocky worlds bookending a pair of gas-rich planets. Around the star LHS ...

We know that our Solar System is not the blueprint for all planetary systems out there. There are gas giant planets orbiting ...

Their observations of a faint, cool M-dwarf star called LHS 1903 revealed a system with a rocky world at its outer edge. LHS ...

“It’s all I ever wanted to do,” said Connolly, founding chair and professor in the Department of Geology within the School of Earth & Environment and a research associate in the Department of Earth ...

NASA shared some new infrared images of the 3I/ATLAS interstellar comet this week, showing the visitor brightening up in a dramatic outburst while exiting a solar system. The images were taken by the ...

This Hubble Space Telescope image shows the largest planet-forming disk ever observed around a young star. It spans nearly 400 billion miles — 40 times the diameter of our solar system. Credit: NASA, ...
