Astrophysicists in Australia have shed new light on the state of the universe 13 billion years ago by measuring the density of carbon in the gases surrounding ancient galaxies.
The study adds another piece to the puzzle of the history of the universe.
"We found that the fraction of carbon in warm gas increased rapidly about 13 billion years ago, which may be linked to large-scale hea Solved: The Mystery of the Cloudy Filters

There's a mystery happening in some satellites facing the Sun, and scientists from the National Institute of Standards and Technology (NIST) and the Laboratory for Atmospheric and Space Physics (LASP) are on the case. The team has been trying to figure out what is clouding up and compromising the performance of tiny, thin metal membranes that filter sunlight as it enters detectors that monitor t Astronomers detect radio recombination lines of carbon oxygen ions for first time

A research team from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has detected radio recombination lines (RRLs) of ions heavier than helium for the first time, using the TianMa 65-m Radio Telescope (TMRT). These lines were assigned to carbon and/or oxygen ions.

Visible light is just one part of the electromagnetic spectrum that astronomers use to study the universe. The James Webb Space Telescope was built to see infrared light, other space telescopes capture X-ray images, and observatories like the Green Bank Telescope, the Very Large Array, the Atacama Large Millimeter Array and dozens of other observatories around the world work at radio wavelengths AST SpaceMobile Announces Teaming Agreement with Fairwinds Technologies

Japan's next-generation H3 rocket failed after liftoff on Tuesday, with the space agency issuing a destruct command after concluding the mission could not succeed.
The failure is a blow for Japan's space agency JAXA, after the rocket failed to even lift off on its first try last month.

In some sectors of the space industry, innovative technologies from startups don’t stand much of a chance to be part of a DoD program due to institutional and cultural barriers, said Jordan Noone, co-founder and general partner of Embedded Ventures.
NASA's Curiosity views first 'sun rays' on Mars

Martian sunsets are uniquely moody, but NASA's Curiosity rover captured one last month that stands out. As the sun descended over the horizon on Feb. 2, rays of light illuminated a bank of clouds. These "sun rays" are also known as crepuscular rays, from the Latin word for "twilight.
Climate change is launching a mutant seed space race

Hurtling around the Earth at more than 20 times the speed of sound, some of the tiniest life forms aboard the International Space Station are on a mission to feed people on a warming planet.
Seeds of sorghum and cress launched into orbit by the International Atomic Energy Agency are tethered to the capsule via a thin metal box. That's exposing them to more-intense solar radiation in a trial to induce genetic mutations so they can survive hotter temperatures, drier soils, spreading pestilence and rising sea levels.
"Most astrobotany until now has been to test how plants can be grown to feed astronauts for eventual space colonies," Shoba Sivasankar, the IAEA's head of genetics and plant breeding, said at her lab outside Vienna. "This experiment is different because it is designed to help people on Earth adapt to climate change."
Farmers from Argentina to California, France and India are struggling to maintain yields amid global warming, with rising prices for the key crops used to bake bread weighing on political stability. Drought gripping North Africa is curbing local wheat harvests, potentially boosting demand in one of the world's top import regions.

NASA delivers hardware for commercial lunar payload mission

Ever wondered how your phone knows exactly where you are? Or how it can provide directions from one place to another?
In the United States, we rely on the Global Positioning System (GPS)—a satellite constellation orbiting Earth that provides precise location and timing information. What a lot of people don't know is that GPS is just one constellation of location and timing satellites. There are currently six GPS-like systems, known as global navigation satellite systems, or GNSS, that provide navigation services to Earthlings traveling the globe.
But what if we could use these Earth-based systems beyond our planet?
In 2024, as part of the NASA Commercial Lunar Payload Services (CLPS) initiative, Firefly Aerospace will land the "Blue Ghost" lander on the lunar surface.

ESA’s HydroGNSS mission will now comprise two identical satellites to halve the time it takes to revisit the same place on Earth’s surface and re-measure various climate variables such soil moisture. Having two satellites in orbit will significantly improve the science that this exciting new Scout mission will yield.
