Growing Future Meals in Space Will Require Human Waste

An artist's concept depicts a greenhouse on the surface of Mars. Plants are growing with the help of red, blue, and green LED light bars and a hydroponic cultivation approach. Other methods using soil simulants should also contribute to long-term food production on the Moon and Mars. Image credit: SAIC

Future farmers on the Moon and Mars will have a big challenge: how to grow healthy food in two extremely unhealthy environments. That's because the soil on both worlds isn't at all hospitable to plants and animals. Neither are other conditions. Both are irradiated worlds, Mars has a thin atmosphere and the Moon has none at all. So, how will future colonists on either world grow their food?

Jupiter Is Smaller and Flatter Than Previously Thought

Jupiter is the largest planet in the solar system and has proudly boasted about this since time immemorial, with its scientific confirmation occurring by Galileo Galilei in 1610. It was later found that Jupiter has a bulging equator caused by its rapid rotation, turbulent atmosphere, and complex interior mechanisms despite its massive size, and scientists have even measured its “waistline” down to a tenth of a kilometer. Now, imagine being the largest planet in the solar system and you’re told you’re not as big as you thought. Where probably most humans would be thrilled to find this out, how do you respond if you’re Jupiter?



The LOFAR Telescope Produces the Most Detailed Radio Map of the Universe Ever

The radio telescope LOFAR, with a major contribution from Leiden Observatory, has produced the most detailed radio map of the Universe ever made. Never before have so many cosmic radio sources been captured in a single survey: 13.7 million.



6 Million Years Ago Something Slammed Into Modern-Day Brazil

These tektites found in Brazil are the evidence of an ancient impact. They're pebble-sized pieces of glass formed in the heat of a collision. The impact occurred about 6 million years ago and spread tektites over three Brazilian provinces. Image Credit: Álvaro Penteado Crósta/IG-UNICAMP

Researchers in Brazil have discovered another tektite field. Tektites are gravel-sized chunks of natural glass formed by impacts and spread over a wide area. Their presence indicates that a powerful impact occurred 6 million years ago.



JWST Digs Into the Uranian Ionosphere

JWST's NIRSpec instrument detected two bright auroral bands near Uranus’s magnetic poles, together with reduced emission and ion density in part of the region between the two bands (a feature likely linked to transitions in magnetic field lines).

Uranus is a planet that seems to roll around on its side as it orbits the Sun. That's because it's tipped over, with an axial tilt of 97.8 degrees. That weird tilt gave the James Webb Space Telescope (JWST) a chance to probe the ionosphere using the Near Infrared Spectrometer (NIRSpec) instrument. An international team of astronomers used the data to map the vertical structure of that region and detect faint auroral displays.

A Method for Extracting Oxygen from Extraterrestrial Soils Just Passed a Major Test

NASA’s Carbothermal Reduction Demonstration (CaRD) project completed an important step toward using local resources to support human exploration on the Moon.



Europa and Other Jovian Moons May Have Formed With Their Own Supply of Life's Building Blocks

This graphic shows how complex organic molecules could've formed in the Solar System's protoplanetary disk. UV radiation drives their formation, and the molecules then migrated through the disk. New research shows that the same thing happened in Jupiter's circumplanetary disk, and that as the Galilean moons formed, they formed with some of life's molecular building blocks.

Complex Organic Molecules (COMs) are important building blocks for life. They can form in space and be delivered to planets. But new research shows some of them can form in circumplanetary disks where moons form, boosting the prospects for life in Europa's ocean.
