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 ...

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, ...

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 ...

The infrared space telescope also detected water vapor, carbon dioxide and organic compounds streaming from the departing comet two months after it made its closest approach to the sun. When you ...

For millions of years, a frozen wanderer drifted between the stars before slipping into our solar system as 3I/ATLAS—only the third known interstellar comet ever spotted. When scientists turned NASA’s ...

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

It might not look like much, but a star system shouldn’t look like this (Picture: European Space Agency) Scientists have discovered something that they previously thought wasn’t possible – an ‘inside ...

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 ...
