Sebastian Zieba: “Since LHS 3844 b lacks such a silicate crust, one may conclude that Earth-like plate tectonics does not apply to this planet, or it is ineffective. This planet likely only contains little water.” buff.ly/i0792ak

Red dwarf stars frequently host small rocky planets but lack mid-sized "sub-Neptunes," likely because intense stellar radiation strips away their atmospheres to leave behind bare rocky cores. buff.ly/IIujnjC

Dr. Andrew Ashton: “On Earth, we get accustomed to certain wave dynamics. But with this model, we can see how waves behave on planets with different liquids, atmospheres, and gravity, which can kind of challenge our intuition.” buff.ly/2Etqh8l

Absolutely incredible and breathtaking image of Earth taken by Artemis II from the far side of the Moon. This image symbolizes decades of painstakingly waiting for humans to return to the Moon's vicinity for the first time since Apollo 17 in 1972.

Earthset. The Artemis II crew captured this view of an Earthset on April 6, 2026, as they flew around the Moon. The image is reminiscent of the iconic Earthrise image taken by astronaut Bill Anders 58 years earlier as the Apollo 8 crew flew around the Moon.
