Dark energy: Neutron stars will tell us if it's only an illusion
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.

Future tokamak fusion power reactors will generate heat beyond what current materials can withstand. Scientists have proposed various methods for cooling the edge of the magnetically confined fusion fuel, or plasma, to protect the walls of the surrounding tokamak. One approach is injecting impurities in the form of gases to help radiate away excess heat. However, there is a limited range of gase NASA's Angie Jackman works to develop rocket that will bring Mars samples to Earth
Huntsville AL (SPX) Mar 09, 2022
Right now, some 182 million miles separate the red clay of Alabama from the dusty red planet Mars. But groundbreaking flight hardware developed at NASA's Marshall Space Flight Center in Huntsville, Alabama, will soon close that distance.
The new hardware is an integral component of the Mars Sample Return campaign, a historic endeavor that will, for the fir Confessions of a former fireball - how Earth became habitable
Researchers at Yale and Caltech have a bold new theory to explain how Earth transformed itself from a fiery, carbon-clouded ball of rocks into a planet capable of sustaining life.
The theory covers Earth's earliest years and involves "weird" rocks that interacted with seawater in just the right way to nudge biological matter into existence.
"This period is the most enigmatic time in NASA to share tools, resources at upcoming agriculture conference
NASA will participate in the 2022 Commodity Classic conference, America's largest farmer-led, farmer-focused educational and agricultural experience.
Agency representatives will discuss information, tools, and resources, drawn from the NASA's Earth observation satellites and science research. Farmers and others regularly make decisions about water management, planting, and market decisions Iran says puts new military satellite in orbit
Iran announced Tuesday it had successfully placed a military satellite in orbit, as talks on reviving a 2015 nuclear deal between Tehran and major powers reach a critical stage.
"Iran's second military satellite - named Nour-2 - has been launched into space by the Qassed rocket of the aerospace wing of the Revolutionary Guards and successfully placed in orbit 500 kilometres (310 miles) a SpaceX plans another Starlink launch as Ukraine uses the service during conflict
SpaceX plans to launch more Starlink communications satellites from Florida on Wednesday as the Ukrainian government uses the service during its defense against the Russian invasion.
The use of satellite communications by defenders in a conflict, where ground communications may be destroyed at any moment, can make a big difference in the outcome, John Scott Railton of the University of Rocket Lab begins qualification of highest performing space solar cell technology
Rocket Lab USA, Inc. reports that its next-generation solar cell technology is transitioning into qualification. The cell is the next product from SolAero's patented Inverted MetaMorphic (IMM) solar cell technology, dubbed IMM-ss, that is expected to exhibit a conversion efficiency of ~33.3% in volume production. IMM-ss is the 4th generation IMM product created by SolAero Technologies Inc. (SolA Data from Mars rover Zhurong shows evidence of wind, and possibly water, erosion
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.
First photos from the Moon under the hammer in Denmark
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.
