Scientists find water vapor in a super-Earth’s atmosphere

It’s a first-ever detection of water vapor in a super-Earth’s atmosphere, orbiting in the habitable zone of its star, 110 light-years away. The discovery supports the possibility that our galaxy contains many such habitable worlds.

Did underground explosions create Titan’s lakes?

The lakes on Saturn’s moon Titan are filled with liquid methane, not water, and some are surrounded by steep rims. A new study suggests these features might have been caused by explosions of warming nitrogen, which created Titan’s lake basins long ago.

What has China’s rover found on the moon’s far side?

Chinese media have reported that the Yutu-2 rover has discovered a “gel-like” substance in a crater on the far side of the moon. It sounds intriguing, but details are still scarce.

What asteroid Ryugu told us

The Hayabusa2 mission has confirmed that – if asteroid Ryugu or a similar asteroid were to come dangerously close to Earth – we’d need to take care in trying to divert it, lest it break up into fragments that might then impact Earth.

Have astronomers found a hyper-volcanic exomoon?

Astronomers have found evidence for a possible exomoon orbiting a gas giant planet 550 light-years away. If they’re interpreting the evidence correctly, this moon would be a place of destruction, even more volcanically active than Jupiter’s famous volcanic moon, Io.
