The light, rare element boron, better known as the primary component of borax, a longtime household cleaner, was almost mined to exhaustion in parts of the old American West. But boron could arguably be an unsung hero in cosmic astrobiology, although it's still not listed as one of the key elements needed for the onset of life. from Universe Today https://ift.tt/mlSqcU9 via IFTTT

Our current understanding of the Cosmos shows that structures emerge hierarchically. First there are dark matter densities, then dwarf galaxies. Those dwarfs then merge to form more massive galaxies, which merge together into even larger galaxies. Evidence of dwarf galaxy mergers is difficult to obtain, but new research found some in the Milky Way's halo. from Universe Today https://ift.tt/DXpfOim via IFTTT

Dark matter remains invisible to our telescopes, yet its gravitational fingerprints pervade the universe. Using NASA's James Webb Space Telescope, scientists have produced one of the most detailed dark maps ever created, revealing with unprecedented clarity how dark matter and ordinary matter have grown up together. The map shows that wherever galaxies cluster in their thousands, equally massive concentrations of dark matter occupy the same space, a close alignment that confirms dark matter's gravity has been shepherding regular matter into stars, galaxies, and ultimately the complex planets capable of supporting life. from Universe Today https://ift.tt/7epk4c8 via IFTTT

Lately we’ve been reporting about a series of studies on the Habitable Worlds Observatory (HWO), NASA’s flagship telescope mission for the 2040s. These studies have looked at the type of data they need to collect, and what the types of worlds they would expect to find would look like.

There’s a bright side to every situation. In 2032, the Moon itself might have a particularly bright side if it is blasted by a 60-meter-wide asteroid. The chances of such an event are still relatively small (only around 4%), but non-negligible. And scientists are starting to prepare both for the bad (massive risks to satellites and huge meteors raining down on a large portion of the planet) and the good (a once in a lifetime chance to study the geology, seismology, and chemical makeup of our nearest neighbor).

Thousands of pieces of abandoned spacecraft orbit Earth, and when gravity finally pulls them down, authorities rarely know exactly where they'll land. Now researchers at Johns Hopkins University have demonstrated a clever solution. Surprisingly they have found using earthquake detecting seismometers they can track falling space debris in real time by listening for the sonic booms it produces. The technique successfully traced a Chinese spacecraft module as it streaked across California at Mach 25-30, revealing its actual trajectory lay 25 miles north of predictions, a significant improvement that could help authorities quickly locate potentially toxic debris and protect people from contamination. from Universe Today https://ift.tt/6MsG5n1 via IFTTT

Some really unique science can be done during a total solar eclipse. Totality is the one time we can see the elusive corona of the Sun, the pearly white segment of our host star’s lower atmosphere where space weather activity originates. The trouble is, totality is fleeting. What researchers really need are eclipses on demand. ESA’s innovative Proba-3 mission does just that, by making use of a free-flying occulting disk.

If humans are ever going to expand into space itself, it will have to be for a reason. Optimists think that reason is simply due to our love of exploration itself. But in history, it is more often a profit motive that has led humans to seek out new lands. So, it stands to reason that, in order for us to truly begin space colonization, we will have to have a business-related reason to do so.

The early stage of giant telescope development involves a lot of horse-trading to try to appease all the different stakeholders that are hoping to get what they want out of the project, but also to try to appease the financial managers that want to minimize its cost. Typically this horse-trading takes the form of a series of white papers that describe what would be needed to meet the stated objectives of the mission and suggest the type of instrumentation and systems that would be needed to achieve them. One such white paper was recently released by the Living Worlds Working Group, which is tasked with speccing out the Habitable Worlds Observatory (HWO), one of the world’s premiere exoplanet hunting telescopes that is currently in the early development stage. Their argument in the paper, which is available in pre-print on arXiv, shows that, in order to meet the objectives laid out in the recent Decadal survey that called for the telescope, it must have extremely high signal-to-noise r...

Inside the cores of ice giant planets, the pressure and temperature are so extreme that the water residing there transitions into a phase completely unfamiliar under the normal conditions of Earth. Known as “superionic water”, this form of water is a type of ice. However, unlike regular ice it’s actually hot, and also black. For decades, scientists thought that the superionic water in the core of Neptune and Uranus is responsible for the wild, unaligned magnetic fields that the Voyager 2 spacecraft saw when passing them. A series of experiments described in a paper published in Nature Communications by Leon Andriambariarijaona and his co-authors at the SLAC National Accelerator Laboratory and the Sorbonne provides experimental evidence of why exactly the ice causes these weird magnetic fields - because it is far messier than anyone expected. from Universe Today https://ift.tt/YVUuKz6 via IFTTT
