Water rich asteroids came from far outside the asteroid belt
Thursday, 23 February 2023 04:31
Where did the water that makes up Earth's oceans come from? This question has not yet been definitively answered. When Earth was formed, 4.5 billion years ago, it received a quantity of volatile substances from the primordial solar nebula, which were outgassed from the interior of the young planet during the solidification of an early magma ocean and through active volcanism.

A team of astronomers led by Carnegie's Shubham Kanodia has discovered an unusual planetary system in which a large gas giant planet orbits a small red dwarf star called TOI-5205. Their findings which are published in The Astronomical Journal, challenge long-held ideas about planet formation.

The CARMENES program, led by a consortium of Spanish and German research institutions, in which the Max Planck Institute for Astronomy (MPIA) is a partner, has released 20,000 observations of more than 300 stars. These measurements led to the discovery of 59 planets, with a dozen being potentially habitable. This spectroscopic data set was obtained at the Calar Alto Observatory in Spain and is n Chandra discovers giant black holes on collision course

Astronomers have discovered the first evidence for giant black holes in dwarf galaxies on a collision course. This result from NASA's Chandra X-ray Observatory has important ramifications for understanding how the first wave of black holes and galaxies grew in the early universe.

In a new study, an international team of astrophysicists has discovered several mysterious objects hiding in images from the James Webb Space Telescope: six potential galaxies that emerged so early in the universe's history and are so massive they should not be possible under current cosmological theory.
Each of the candidate galaxies may have existed at the dawn of the universe roughly 50 Webb observes a globular cluster sparkling with separate stars

On June 20, 2022, the James Webb Space Telescope spent just over one hour staring at Messier 92 (M92), a globular cluster 27,000 light-years away in the Milky Way halo. The observation - among the very first science observations undertaken by Webb - is part of Early Release Science (ERS) program 1334, one of 13 ERS programs designed to help astronomers understand how to use Webb and make the mos Sidus Space secures additional launches with SpaceX

A century ago, the British archaeologist Howard Carter opened Tutankhamun's burial chamber. For years he had been searching for the pharaoh's tomb in the Valley of the Kings, northwest of the Upper Egyptian city of Luxor. Having almost given up, he found Tutankhamun's tomb in the winter of 1922. However, several months of careful preparations were needed before the archaeologist could enter the Relativity Space sets date for first Terran 1 launch

Treating lunar soil to create fertilizer for growing plants on the moon
Wednesday, 22 February 2023 17:42
Sooner or later, settlers on the moon will have to become farmers. A new ESA Discovery project led by Norway's Solsys Mining is looking into the treatment of lunar soil to create fertilizer for growing plants.
The good news is that analysis of lunar samples returned to Earth in the past by moonwalkers and robots shows sufficient essential minerals are available for plant growth, apart from nitrogen compounds. The bad news is that lunar soil (or "regolith") compacts in the presence of water, creating problems for plant germination and root growth.
Hydroponic farming therefore offers a practical alternative; this type of agriculture involves feeding plant roots directly with nutrient-rich water, without the need for soil. The potential is still there however to put lunar regolith to work, on the basis of "in-situ resource utilization"—or living off the land.
The "Enabling Lunar In-Situ Agriculture by Producing Fertilizer from Beneficiated Regolith" project, led by Solsys Mining with Norway's Geotechnical Institute (NGI) and Centre for Interdisciplinary Research in Space (CIRiS), involves studying a combination of mechanical, chemical and biological processes to extract mineral nutrients from the regolith.
