First its rotation slowed between March and May 2017, taking 46 hours to complete a spin where it had once taken only 20 hours. This occurred as the comet neared its closest point to the sun, roughly ...

Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...

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

Earth and Mars were formed from material that largely originated in the inner solar system; only a few percent of the building blocks of these two planets originated beyond Jupiter's orbit. A group of ...

There are some clocks, mostly in or around international airports, which have multiple faces to show the time at various ...

There seems to be an enormous cloud of dark matter next to our solar system. We have never found one of these clouds in the Milky Way before, but precise cosmic clocks called pulsars finally made it ...

Experience space like never before with this Python simulation of the ISS orbit – upgraded animation! 🌌 Watch the International Space Station (ISS) move along its trajectory with realistic ...

Supercomputer simulations identify stellar rotation as the mechanism driving chemical mixing in red giants, explaining long-observed surface composition changes during stellar evolution.

Recently, scientists discovered the fastest-spinning large asteroid in the solar system. It’s about the length of eight football fields — but it fully rotates every two minutes, or even a little ...

Solar storms and coronal mass ejections (CMEs) can disrupt everything from satellites to power grids. A new AI tool, PINNBARDS, developed by Southwest Research Institute (SwRI) and NSF-NCAR, can now ...

An idea about the sun’s magnetic field called the terminator model could help predict dangerous space weather more accurately ...
