The Majestic Valleys of Mars May Not Have Been Carved by Rivers After All
The question of whether ancient life could have existed on Mars centres on the water that once flowed there, but new research published Monday suggests that many of the Red Planet's valleys were gouged by icy glaciers not rivers.

We Thought We Knew How Sperm Swam, But It Was Just an Optical Illusion
Sperm is critical for the fertilisation of almost every living organism on our planet, including humans. To reproduce, human sperm have to swim a distance equivalent to climbing Mount Everest to find the egg.

Planet-Scale Wave Has Been Hiding in The Toxic Clouds of Venus For Decades
Deep in the thick, poisonous clouds wrapped around Venus, the atmosphere is behaving very oddly. A giant, previously unknown planet-scale wall of cloud travels westward around the planet every 4.9 days - and apparently has been doing so since at least 1983.…

Russian cosmonaut Ivan Wagner from the ISS captured on video a group of five unidentified objects flying over the Earth.
"At 9-12 seconds, 5 objects appear, flying in a parallel course and at the same distance from each other. What do you think it can be - meteors, satellites, or ...?", Wagner said on his Twitter. "The information has been brought to the attention of the management of the State Corporation Roscosmos. The materials have been transferred for analysis," the cosmonaut wrote.

This comparison shows a stunning view of the 30 trillion-km-wide Helix Nebula acquired with the VISTA #telescope in infrared light along with a more familiar view in visible light from the #ESO 2.2-metre telescope. The infrared vision of VISTA reveals strands of cold nebular gas that are much less prominent in visible light images of the Helix.
