Galaxies go on a deep dive and leave fiery tail behind
Thursday, 08 June 2023 11:18
A group of galaxies is plunging into the Coma galaxy cluster and leaving behind an enormous tail of superheated gas. Astronomers have confirmed this is the longest known tail behind a galaxy group and used it to gain a deeper understanding of how galaxy clusters - some of the largest structures in the universe - grow to their enormous sizes.
Astronomers trained NASA's Chandra X-ray Observa Detectors could improve views of gamma-ray events

Using technology similar to that found in smartphone cameras, NASA scientists are developing upgraded sensors to reveal more details about black hole outbursts and exploding stars - all while being less power hungry and easier to mass produce than detectors used today.
"When you think about black holes actively shredding stars, or neutron stars exploding and creating really high-energy bur VLBA reveals complexity of 'average' space explosions in Novae
Thursday, 08 June 2023 11:18
While studying classical novae using the National Radio Astronomy Observatory's Very Long Baseline Array (VLBA), a graduate researcher uncovered evidence the objects may have been erroneously typecast as simple. The new observations, which detected non-thermal emission from a classical nova with a dwarf companion, were presented at a press conference during the 242nd proceedings of the American Remains of an extinct world of organisms discovered
Thursday, 08 June 2023 11:18
Newly discovered biomarker signatures point to a whole range of previously unknown organisms that dominated complex life on Earth about a billion years ago. They differed from complex eukaryotic life as we know it, such as animals, plants and algae in their cell structure and likely metabolism, which was adapted to a world that had far less oxygen in the atmosphere than today. An international t New study identifies mechanism driving the sun's fast wind
Thursday, 08 June 2023 11:18
The fastest winds ever recorded on Earth reached more than 200 miles per hour, but even those gusts pale in comparison to the sun's wind.
In a paper published June 7, 2023 in the journal Nature, a team of researchers used data from NASA's Parker Solar Probe to explain how the solar wind is capable of surpassing speeds of 1 million miles per hour. They discovered that the energy released fr Albedo expands staff and facilities

NASA concerned Starship problems will delay Artemis 3
Thursday, 08 June 2023 08:45
NASA has growing concerns that the lunar lander version of SpaceX’s Starship vehicle will not be ready in time for the Artemis 3 mission in late 2025, given the amount of work needed to get the vehicle ready.
Cheops explores mysterious warm mini-Neptunes

ESA’s exoplanet mission Cheops confirmed the existence of four warm exoplanets orbiting four stars in our Milky Way. These exoplanets have sizes between Earth and Neptune and orbit their stars closer than Mercury our Sun.
These so-called mini-Neptunes are unlike any planet in our Solar System and provide a ‘missing link’ between Earth-like and Neptune-like planets that is not yet understood. Mini-Neptunes are among the most common types of exoplanets known, and astronomers are starting to find more and more orbiting bright stars.
Mini-Neptunes are mysterious objects. They are smaller, cooler, and more difficult to find than the so-called hot

Airbus develops a system to extract oxygen and metal from lunar regolith
Wednesday, 07 June 2023 19:26
New technologies using material found in space are constantly popping up, sometimes from smaller companies and sometimes from larger ones. Back in 2020, one of the largest companies of them all announced a technology that could have significant implications for the future lunar exploration missions planned over the next ten years. The European aerospace giant Airbus developed the Regolith to OXYgen and Metals Conversion (ROXY) system.
ROXY creates not only oxygen, a resource vital for humans to breathe and also for rocket fuel, but also makes metals that can be used to manufacture tools, equipment, and even structures on the Moon. And it does it simply from the regolith that is present everywhere on the lunar surface.
Space colonies: How artificial photosynthesis may be key to sustained life beyond Earth
Wednesday, 07 June 2023 16:41
Life on Earth owes its existence to photosynthesis—a process which is 2.3 billion years old. This immensely fascinating (and still not fully understood) reaction enables plants and other organisms to harvest sunlight, water and carbon dioxide while converting them into oxygen and energy in the form of sugar.
Photosynthesis is such an integral part of Earth's functioning that we pretty much take it for granted. But as we look beyond our own planet for places to explore and settle on, it is obvious how rare and valuable the process is.
As my colleagues and I have investigated in a new paper, published in Nature Communications, recent advances in making artificial photosynthesis may well be key to surviving and thriving away from Earth.
The human need for oxygen makes space travel tricky. Fuel constraints limit the amount of oxygen we can carry with us, particularly if we want to do long-haul journeys to the moon and Mars. A one-way trip to Mars usually takes on the order of two years, meaning we can't easily send supplies of resources from Earth.
Parker Solar Probe flies into the fast solar wind and finds its source
Wednesday, 07 June 2023 14:00
NASA's Parker Solar Probe (PSP) has flown close enough to the sun to detect the fine structure of the solar wind close to where it is generated at the sun's surface, revealing details that are lost as the wind exits the corona as a uniform blast of charged particles.
It's like seeing jets of water emanating from a showerhead through the blast of water hitting you in the face.
In a paper to be published in the journal Nature, a team of scientists led by Stuart D.
