Organic molecules of unprecedented size discovered on Mars

The longest organic molecules identified to date on Mars have recently been detected by scientists from the CNRS, together with their colleagues from France, the U.S., Mexico, and Spain. These long carbon chains, containing up to 12 consecutive carbon atoms, could exhibit features similar to the fatty acids produced on Earth by biological activity.

Bridging the gap between the cosmic microwave background and the first galaxies

One of the Holy Grails in cosmology is a look back at the earliest epochs of cosmic history. Unfortunately, the universe’s first few hundred thousand years are shrouded in an impenetrable fog. So far, nobody’s been able to see past it to the Big Bang. As it turns out, astronomers are chipping away at that cosmic fog by using data from the Atacama Cosmology Telescope (ACT) in Chile.

Saturday Citations: The universe doesn’t care about your precious standard model

This week, ALMA researchers reported the discovery of oxygen in the most distant known galaxy. Geologists believe unusual structures in rock in the desert regions of Namibia, Oman and Saudia Arabia may be evidence of an unknown microorganism. And a group of physicists may have generated a tiny charge of electricity using the Earth’s rotational energy. But the biggest story by far is the second release of data from the DESI survey of the universe, which could upend the standard model:

Chang’e-6 samples suggest 4.25-billion-year-old impact formed moon’s South Pole–Aitken basin

Scientists have long sought to determine the age of the moon’s South Pole–Aitken (SPA) basin, the largest and oldest known impact crater on the lunar surface. Recently, a research team led by Prof. Chen Yi from the Institute of Geology and Geophysics at the Chinese Academy of Sciences has dated the formation of the basin to 4.25 billion years ago by analyzing the first-ever rock samples returned from the SPA basin by China’s Chang’e-6 mission.

How warp drives don’t break relativity

Somehow, we all know how a warp drive works. You’re in your spaceship and you need to get to another star. So you press a button or flip a switch or pull a lever and your ship just goes fast. Like really fast. Faster than the speed of light. Fast enough that you can get to your next destination by the end of the next commercial break.
