Starting at 12:30 p.m. ET (1730 GMT) on Saturday (Jan. 25), astrophysicist Gianluca Masi of the Virtual Telescope Project will stream live telescope views of all six of the planets in marching order.

Through observations, either with space telescopes or with ground-based equipment, we can find out how planets in our solar system and beyond are structured, what materials they are made of, whether ...

All of our solar system’s planets are lining up to parade through the night sky at once. This extraordinary celestial event will see the sky scattered with seven visible planets in what is known ...

Stargazers will be treated to a rare alignment of seven planets on 28 February when Mercury joins six other planets that are already visible in the night sky. Here's why it matters to scientists.

So you can see every planet in our solar system over the next month ... the Virtual Telescope Project plans to broadcast a live feed from its telescopes in Tuscany. The livestream, below, is ...

A planet-size object that possibly once visited the solar system may have permanently changed our cosmic neighborhood by warping the orbits of the four outer planets, a new study suggests.

One possibility is that a rogue planet, about 1–2 times Earth’s mass, influenced their paths early in the solar system's history. Another enigmatic group comprises high-inclination TNOs ...

In fact, every planet—and every moon—in the solar system will be in the sky during the eclipse. However, that doesn’t mean you’ll see them all. Contrary to what you might have read ...

It is the fastest wind ever measured in a jetstream that goes around a planet. In comparison, the fastest wind ever measured in the Solar System was found on Neptune, moving at 'only' 0.5 km per ...
