Star or not? The common prediction is that the Milky Way will collide with its neighboring galaxy Andromeda in about four billion years. But a new model now describes a different scenario. For example, two other galaxies – the Large Magellanic Cloud and the spiral galaxy M33 – influence the galactic orbits and thus the … Read more
Underground quantum mail: Quantum transmission has successfully passed its first long-term test in New York. For 15 days, entangled photons were sent over a 34-kilometer-long telecommunications line under the city – without intermediate calibration or other human assistance. Successfully: Despite vibrations and other disruptive effects typical of cities, the quantum transfer achieved a reliability of … Read more
Hidden reservoir: There may be a massive reservoir of liquid water seven miles beneath the Martian surface — enough to flood the entirety of Mars to a height of one to two kilometers, data from NASA’s Mars InSight probe suggests. The water is hidden in cracks and pores in fractured crustal rock and may have … Read more
Double benefit: Old concrete from demolished buildings can help bind the greenhouse gas carbon dioxide and at the same time become new bricks. This is made possible by a method in which old concrete is crushed, soaked in carbon dioxide and dried in layers with CO2. The material absorbs the CO2 and forms a strong, … Read more
press release July 25, 2023 The European Southern Observatory today released a stunning new image that sheds light on how massive planets like Jupiter might form. Using ESO’s Very Large Telescope (VLT) and the Atacama Large Millimeter/submillimeter Array (ALMA), researchers have discovered large clumps of dust near a young star that could collapse and form … Read more
Annual celestial spectacle: The Perseid meteor shower is at its peak today. On Tuesday night, you can expect to see 20 to 30 shooting stars in the sky every hour – including some particularly bright “fireballs.” Weather and visibility conditions are pretty good this year. And besides the Perseids, there’s another celestial spectacle in store … Read more
Exciting phenomenon: Space hurricanes occur above both polar caps of the Earth – gigantic cyclones made of charged particles in the ionosphere, as shown by satellite data. Researchers have detected 256 of these space hurricanes in ten years in the southern polar region alone; such ionospheric cyclones also occur about twelve times a year in … Read more
press release September 22, 2022 Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have discovered signs of a “hot spot” orbiting Sagittarius A*, the black hole at the center of our galaxy. This discovery helps us better understand the complex and dynamic environment of our supermassive black hole. “We think we’re dealing with a hot … Read more
press release June 15, 2022 Astronomers have used new observations with the Atacama Large Millimeter/submillimeter Array (ALMA) to reveal intricate details of the star-forming region 30 Doradus, also known as the Tarantula Nebula. In a high-resolution image released today by the European Southern Observatory (ESO), containing ALMA data, we see the nebula in a new … Read more
press release July 19, 2023 Astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) to discover a possible “sister planet” orbiting a distant star. The team has detected a cloud of debris that could share an orbit with the planet. They believe it is the building blocks of a new planet or the remains of … Read more
