Two weeks after launch, @NASAWebb has hit its next biggest milestone: the mirrors have completed deployment and the next-generation telescope has taken its final form.
Next up for Webb? Five months of alignment and calibration before we start getting images:

A mysterious "moon hut" spotted by China's lunar Yutu 2 rover is actually … an adorable rabbit-shaped rock.
The rock has been nicknamed "jade rabbit" by the Yutu 2 team, which announced its rover's closer inspection of the object on Friday (Jan. 7). The nickname is apt, as the rover's name, Yutu, also translates to "jade rabbit."
The object first appeared in the field of view of Yutu 2's cameras in December, when it looked like a cube-shaped blur on the horizon. The rover is the first to explore the moon's far side, which always faces away from Earth and is more rugged and pitted by craters than the moon's near side. Because the object appeared irregularly symmetrical, with a strange flat top, researchers with the China National Space Administration outreach program Our Space joked that it might be the hut of alien pioneers, Live Science previously reported.

The sun used to have rings like Saturn
Before Earth and the other planets in our solar system existed, the sun may have been surrounded by giant rings of dust similar to Saturn's, according to a new study.
Those rings of dust may have prevented Earth from growing into a "super-Earth" — a type of planet that is about twice the size of Earth and up to 10 times its mass, according to NASA. Astronomers have discovered super-Earths orbiting about 30% of sun-like stars in our galaxy.
