The rocky worlds have the potential to harbor liquid water, but until now scientists have been unable to tell if they have atmospheres.

In June, Mercury, Venus, Mars, Jupiter and Saturn will all be visible in the sky in the same order as they orbit the sun—for the first time in 18 years.

The five planets, Mercury, Venus, Mars, Jupiter and Saturn—will all be visible at once throughout the month of June in the same order as they orbit the sun.

The Earth consists of four main layers: the crust, the mantle, the outer core and the inner core.

The two bright planets will be visible to the naked eye when nestled close together. A live stream is also planned.

"Kids are mean and will eat a kid named Jupiter for lunch," one comment read.

In an influential report known as the decadal survey, planetary scientists have said visiting Uranus should be a priority for NASA.

The area, which scientists have named the Wyoming Crater Field, is in a triangular area between the cities of Laramie, Douglas and Casper.

While it isn't exactly a scientifically proven theory, many believe that mercury in retrograde wreaks havoc on our personal lives, and there are plenty of memes out there to prove it.

The public are being asked to label images taken by NASA's Perseverance and other Mars rovers in order to train an algorithm that will aid Martian navigation.

The floods resulted from crater breaches that created deep rivers on the Red Planet's surface like the "Grand Canyon of Mars" Loire Vallis, new research shows.

September's moon falls days before the Autumn equinox.

The Solar Orbiter spacecraft, jointly operated with the European Space Agency, passed within 4,967 miles of the planet's surface on August 9.

For the first time in over 30 years, NASA will be sending missions DAVINCI+ and VERITAS to Venus, an expedition expected to launch in the late 2020s.

A study sheds new light on the distribution of metals in the lunar subsurface.

There's a lot to be frightened of in the great infinite nothingness of outer space.

"It seems that an important part of the Milky Way's stellar mass was formed due to the interactions with Sagittarius and wouldn't exist otherwise," scientist Carme Gallart said.

Researchers identified the minor planets beyond the orbit of Neptune.

Data indicates that the object could measure anywhere between 1.1 and just over 2.6 miles in diameter, based on its observed magnitude.

The planet is located around 1,000 light-years from Earth and experiences average temperatures of more than 1,800 degrees Fahrenheit.

The tropical year—or the length of time it takes for the Earth to go from one equinox to the next—is 365 days, 5 hours, 48 minutes and 45 seconds long.

This celestial event only takes place around 13 times a century.

Mercury transits take place only around 13 times a century.

No, the first day of fall is technically not marked by the return of the pumpkin spice latte (although, unofficially, it kind of is).

The latest findings could help to explain some puzzling measurements collected by the Juno spacecraft, which is currently orbiting the planet.

The bright side is that you likely won't notice them in a really personal conflicting way like when Mercury is retrograde, according to astrologers.

When exactly plate tectonics emerged and how it has evolved through time are two of the most significant and hotly debated questions in Earth sciences today.

More than 4,000 planets beyond our solar system have been discovered since the first in 1992.
