Astronomers have discovered two new exoplanets that are similar to other worlds found in the Milky Way, but unlike any in our ...

one which can offer superb views of the other bodies in the solar system. But which one to choose? We've got you covered with our guide to the best telescopes for seeing planets. There are several ...

“When compared to our solar system, each of the four planets are inside the distance of Mercury’s orbit,” Basant said. The planets closely orbit Barnard’s Star, zipping around their ...

“[Planetary scientists] have thought our solar system is not standard in its spacings,” says astronomer Juliette Becker of the University of Wisconsin-Madison. In particular, the rocky planets ...

Using advanced simulations, the researchers propose that these planets emerge from distinct rings of planetesimals, providing fresh insight into planetary evolution beyond our solar system.

a fraction of our solar system's 4.6 billion years. Still hot from their violent formation, HR 8799 planets emit large amounts of infrared light that give scientists valuable data on how their ...

The findings suggest planets in a system 130 light-years away likely built up solid cores before attracting gas, much like our solar system’s gas worlds. Webb’s coronagraphs allow direct atmospheric ...
