(CNN) If you step out the door on a clear, dark night at this time of year, you'll find the great constellation called Ursa Major high in the sky below Polaris, the pole star.

This week in space: China lands on Mars, new habitable planets revealed
"This Week In Space" brings you what’s new and exciting in space exploration and astronomy once a week, every week. From supernovae to SpaceX or Mars missions to black holes, if it’s out of this world, it’s covered here:
China has officially become an interplanetary nation. Last Friday, its Zhurong rover made history by touching down safely on the surface of Mars. The People’s Republic is only the third country to ever accomplish this feat, following the US and Soviet Union.
On The Formation Of Terrestrial Planets Between Two Massive Planets: The Case Of 55 Cancri -
Examples of final systems in scenarios A (500 embryos, upper) and B (1500 embryos, lower). The formed planets and 55 Cnc f,d are all shown on the (𝑎, 𝑒) plane with the size proportional to the cube root of mass and the color indicating water mass (in 𝑂⊕). Initial 55 Cnc f and d are represented by open circles. The grey shadow indicates the potentially habitable zone (0.59–1.43 AU). left column: Δ𝑎 𝑓 0, middle column: Δ𝑎 𝑓 > 0, Δ𝑀𝑓 > 0, right column: Δ𝑎 𝑓 > 0, Δ𝑀𝑓 < 0.
Considering the huge computational resources required by smoothed particle hydrodynamics (SPH) simulations and the overestimation of post-collision materials from perfect merging, we develop a statistical method to deal with collisions during the formation of planetary systems by introducing random material loss.
Utah Skies: Crescent Moon Meets Three Planets | UPR Utah Public Radio
As the moon orbits Earth we see the different phases it goes through during the month. From the new moon to the full moon the illuminated crescent grows in size each day, this is called a waxing moon. From full moon to new moon the illuminated area grows smaller and is known as a waning moon.
The waxing phase begins with the new moon. The lunar disk is not visible to the unaided eye as the moon in its orbit around the Earth lies between the Earth and the Sun. The moon's near side is dark from an observer on the Earth, while the side facing away from the earth is illuminated.
5 Futurama Planets That Would Be Amazing To Visit (& 5 That Would Be Terrifying)
Futurama is a cult classic comedy that has made viewers laugh, cry, and wonder. As Planet Express is an interstellar delivery company, viewers are shown scores of planets throughout Futurama's sporadic run. Even Earth sometimes felt like a weird alien planet with some of the liberties taken about what it would be like 1,000 years in the future.
Many of the planets seen are wondrous places with incredible sights and fascinating creatures. Some planets also provide background on certain characters or make an excellent satire of something in the real world. There are also some planets that have such frightening creatures or such deadly atmospheres that most fans are thankful they don't exist.
Every Returning Planet In Ratchet & Clank: Rift Apart So Far
There have been various planets shown so far, such as Urfdah Mesa, Corson V: Nefarious City, and Blizar Prime: Blizar Mines. Going off previous titles, it's safe to assume that there might be more than just the 7 worlds that have been teased in gameplay, as each previous game had 10 or more worlds. However, those games didn't have the scope of Ratchet & Clank: Rift Apart . While there are various new worlds to explore, fans may be wondering which planets are returning.
