  Pasadena CA (JPL) Apr 22, 2022 Not that it matters, but exactly 100 sols ago, on January 7th, we were planning sols 3351 and 3352, and it was this blogger's turn to report on what was happening. Apparently, we were marvelling at the landscape - and dealing with a rock under the foot, well, the wheel. Tosol, we were again dealing with a rock right under the rover, but this time, we were excited about it as the rover was in a stable position parked on a big piece of bedrock, presenting itself flat as a pancake, ready to be brushe ... read more |

Diverse microbial life existed on Earth at least 3.75 billion years ago, suggests a new study led by UCL researchers that challenges the conventional view of when life began.
For the study, published in Science Advances, the research team analysed a fist-sized rock from Quebec, Canada, estimated to be between 3.75 and 4.28 billion years old. In an earlier Nature paper*, the team found tiny ... more |

In 2006, the Cassini spacecraft recorded geyser curtains shooting forth from "tiger stripe" fissures near the south pole of Saturn's moon Enceladus - sometimes as much as 200 kilograms of water per second. A new study suggests how expanding ice during millennia-long cooling cycles could sometimes crack the moon's icy shell and let its inner ocean out, providing a possible explanation for the gey ... more |

 Hatfield UK (The Conversation) Apr 15, 2022 
The Hubble Space Telescope has observed the most distant star ever seen - Earendel, meaning morning star. Even though Earendel is 50 times the mass of the Sun, and millions of times brighter, we would not normally be able to see it. We can see it due to an alignment of the star with a large galaxy cluster in front of it whose gravity bends the light from the star to make it brighter and more foc ... more |
