Astronomers found a ‘cold super-Earth’ less than 6 light-years away — and it may be the first rocky planet we’ll photograph be...

Astronomers think they've found a "cold super-Earth." It might be the first exoplanet they photograph with a coming generation of powerful telescopes.
Pluto is over 4.6 billion miles away, but you can explore it from the comfort of your own computer, right now, thanks to Google Maps.

A little-known feature in Google Maps lets you explore planets and moons in our local solar system — here’s how to find it

Most people just use Google Maps to get directions from A to B, but it can also be used to explore other planets beyond our own.

NASA’s $1 billion Juno spacecraft is probing Jupiter’s deepest secrets — here are Juno’s biggest discoveries so far

NASA's Juno probe reached Jupiter in July 2016, and scientists' view of the solar system has not been the same since. The $1 billion mission has taken stunning images of the gas giant and probed its deepest secrets with a suite of instruments.
Is Mercury in retrograde? A few times a year, it is — though it's not likely to have any effect on your day-to-day life.

What ‘Mercury in retrograde’ really means — and why it can’t tell you anything about your life

There's no scientific evidence that astrology can reveal anything about the future or yourself. But Mercury retrograde does refer to a real phenomenon. Here's what it actually means.

Scientists may have just found a lake of liquid water on Mars

Astronomers caught a planet being born for the first time in a stunning new picture

Astronomers have taken the first confirmed picture of a newborn planet. The planet, called PDS 70b, is about 370 light-years from Earth and orbits a dwarf star. A series of images suggests the distant planet has a cloudy atmosphere and is 1,000 degrees Fahrenheit.

NASA’s $1 billion Jupiter probe just beamed back even more jaw-dropping photos of the planet’s tireless storm clouds

Juno, a tennis-court-size NASA probe at Jupiter, recently sent scientists a new batch of data, and the photos it included are even more stunning than the last set. They show powerful cyclones, chaotic cloud bands, and messes of blue-hued patterns near the planet's poles.

Astronomers found new evidence that a giant ghost planet may lurk in our solar system

Researchers identified a small object well past Neptune that seems to rotate as if it's caught in a larger planet's orbit. It's the best evidence yet that there could be a hidden ninth planet.
