Far beyond Neptune, in the frozen depths of the Kuiper Belt, many ancient objects oddly resemble giant snowmen made of ice and rock. For years, scientists wondered how these delicate two-lobed shapes ...

In the distant reaches of the solar system are many icy objects that resemble snowmen. Now, a new study reveals the simple ...

Planetary systems such as our solar system take hundreds of millions of years to evolve. Since humanity has only existed for a sliver of that time, astronomers have only observed planetary systems at ...

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 ...

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, ...

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 ...

An international team of astronomers, after years of work and observations with both ground‑based and space telescopes, has discovered the LHS 1903 planetary system - a red dwarf star orbited by four ...

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 ...

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 ...

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

From the exam room to the classroom, artificial intelligence is no longer just a tool—it's infrastructure. An introduction to our special report on life in the age of AI.
