Jeff Bezos's space colonies would look like cylindersAn artist's concept of an O'Neill space colony, which could theoretically emulate Earth-like living conditions in space. O'Neill space colonies would be large enough to host entire cities, 10,000-foot-tall mountains, and millions of people. AdvertisementBezos isn't suggesting that people will be living in O'Neill space colonies by the end of the century. AdvertisementSaving Earth would be far easier than building Bezos' space colonies, he told BI. Even if we never make it to space colonies, the work of researchers studying extraterrestrial colonization could benefit us here on Earth.

☆ Scientists propose sweeping new law of nature, expanding on evolution

Evolution occurs, it holds, when these various configurations are subject to selection for useful functions. "We have well-documented laws that describe such everyday phenomena as forces, motions, gravity, electricity and magnetism and energy," Hazen said. The subsequent generation of stars that formed from the remnants of the prior generation then similarly forged almost 100 more elements. "Imagine a system of atoms or molecules that can exist in countless trillions of different arrangements or configurations," Hazen said. "Only a small fraction of all possible configurations will 'work' - that is, they will have some useful degree of function.

☆ NASA rover reveals new evidence about organic molecules on Mars
▼ + stars: | 2023-07-13 | by ( Will Dunham | ) www.reuters.com time to read: +4 min

The latest evidence comes from an instrument called SHERLOC mounted on the six-wheeled rover's robotic arm that enables a detailed mapping and analysis of organic molecules. They obtained evidence indicating the presence of organic molecules in multiple rock samples, including some collected for potential return to Earth for future analysis. Signs of organic molecules were first detected on Mars in 2015 by a different rover called Curiosity, followed by more evidence in subsequent years. With Perseverance now detecting possible signatures of organic molecules, the evidence is accumulating that organic molecules may be relatively common on Mars, though at low levels. "There are both biotic and abiotic mechanisms that can form organic molecules.

☆ NASA Mars Ingenuity helicopter broke its own record

CNN —More than a year and a half after its first flight on Mars, the Ingenuity helicopter has set a new record. “Ingenuity’s success has led to NASA’s decision to take two Ingenuity class helicopters on the Mars Sample Retrieval Lander scheduled for later in this decade,” wrote Bob Balaram, Ingenuity chief engineer emeritus, in a NASA blog update. A more capable Mars Science Helicopter with the ability to carry almost 5 kg of science payloads is also in early conceptual and design stages.”Mars sample collectionMeanwhile, the Perseverance rover continues to collect intriguing samples from Mars. The cache will be collected by future missions during the Mars Sample Return campaign and returned to Earth in the 2030s. The Perseverance rover recently used a specialized drill bit to collect its first samples of broken rock and dust.

David Grinspoon, an astrobiologist at the Planetary Science Institute, called the new Webb image “just spectacular beyond words.”“Oh. Young stars, estimated to be only a few hundred thousand years old, are the bright red orbs in the image. New stars form within clouds of dust and gas as dense clumps of mass collapse under their own gravity and begin to heat up. The Webb Telescope captured this dynamic journey in progress, according to Thomas Zurbuchen, the associate administrator of NASA's Science Mission Directorate. These are baby stars that are forming within the gas & dust," he tweeted.
