A huge amount of mysterious dark energy is necessary to explain cosmological phenomena, such as the accelerated expansion of the Universe, with Einstein's theory. But what if dark energy was just an illusion and general relativity itself had to be modified? A new SISSA study, published in Physical Review Letters, offers a new approach to answer this question.

Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers at Leiden Observatory in the Netherlands have for the first time detected dimethyl ether in a planet-forming disc. With nine atoms, this is the largest molecule identified in such a disc to date. It is also a precursor of larger organic molecules that can lead to the emergence of life.

The Amazon rainforest is likely losing resilience, data analysis from high-resolution satellite images suggests. This is due to stress from a combination of logging and burning - the influence of human-caused climate change is not clearly determinable so far, but will likely matter greatly in the future.

It had long been thought that the famous site of Stonehenge served as an ancient calendar, given its alignment with the solstices. Now, research has identified how it may have worked.
New finds about the stone circle's history, along with analysis of other ancient calendar systems, prompted Professor Timothy Darvill to take a fresh look at Stonehenge. His analysis, published in the journal Team chosen to make first oxygen on the Moon

Following a design competition, ESA has selected the industrial team that will design and build the first experimental payload to extract oxygen from the surface of the Moon. The winning consortium, led by Thales Alenia Space in the UK, has been tasked with producing a small piece of equipment that will evaluate the prospect of building larger lunar plants to extract propellant for spacecraft and breathable air for astronauts – as well as metallic raw materials for equipment.

The first NASA photographs taken on the Moon, including the first shot of an "Earthrise" and Buzz Aldrin walking on the surface, will be auctioned off in Copenhagen on Wednesday.
"One of my favourite photos from this fantastic collection depicts a photo of Buzz Aldrin taken by Neil Armstrong, and you can actually see Neil Armstrong being reflected in Buzz Aldrin's visor", Kasper Nielsen, the head of the Bruun Rasmussen auction house's valuation team, told AFP.
A total of 74 unique NASA photographs are up for sale, including 26 taken on the Moon during the Apollo missions in the 1960s and 1970s.
Data from Mars rover Zhurong shows evidence of wind, and possibly water, erosion
Tuesday, 08 March 2022 16:20 Write a comment
A team of researchers affiliated with multiple institutions in China and one each from Canada and Germany, has found data from the Chinese Mars rover Zhurong over its first 60 sols, showing evidence of wind erosion and possibly impacts from water erosion, as well. In their paper published in the journal Nature Geoscience, they discuss what they have found thus far.
China's Mars rover Zhurong has been on the surface of Mars since May of last year. During that time, it has rolled approximately 450 meters over the course of 60 Martian days (sols). Recently, the team working with Zhurong made the data from the rover public. In this new effort, the researchers have been studying the data sent back to learn more about what it has found.
Zhurong was deployed on the planet's Utopia Planitia—a volcanic plain situated in the northern hemisphere.
