For three years they've been one of the strangest puzzles in astronomy. Tiny, mysterious red dots scattered across the early universe, so abundant and so bright that some researchers wondered if they had "broken" cosmology itself. Now the James Webb Space Telescope has captured the most detailed look yet at one of them, and the answer it reveals is as exotic as the name suggests: a star sized object that is, in fact, a black hole wearing a disguise.
Somewhere in the plane of the Milky Way, a dead star is spinning 220 times a second, and it's circling its companion in almost the most perfect orbit astronomers have ever measured. China's giant FAST radio telescope has just found it, and the shape of that orbit is a near flawless record of a billion year relationship between two stars.
In a recent NASA-supported study, researchers assessed Titan's resource base and how it could be leveraged for ISRU. Compared with other locations under study (the Moon, Mars, etc.), they concluded that there is unrivaled potential for human exploration and settlement.
Venus’ extraordinarily slow retrograde rotation was likely caused by a chance encounter with a moon-sized impactor. One that some 4.5 billion years ago likely slammed into our sister planet at a high angle and high velocity.
It’s 2134, and humanity has finally embraced green technologies while ridding the Earth of harmful fossil-burning technologies, most notably gasoline, wood, coal, and oil. As a result, soot has been rendered obsolete, and all commercial products from soot, including shoes, wires, computer products, and eye products, are now produced from eco-friendly technologies. However, the uber-rich who still fancy non-eco-friendly products are willing to pay soot’s weight in gold for it. Therefore, the Exoplanet Research Corporation outfits its best ship to search for soot-enriched exoplanet atmospheres.
NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution of these elements throughout the young solar system. The study, published in Science Advances, examines this history by looking at the ratio of phosphorus to nitrogen in iron meteorites and in younger objects known as chondrites.
A small rock found in the African desert has just handed scientists an extraordinary window into one of the most violent and consequential periods in the history of the Solar System. Inside this lunar meteorite, a chunk of the Moon knocked to Earth by an ancient collision, researchers have found evidence of a massive impact event 3.5 billion years ago, one that matches the timing of known impacts on Earth and in the asteroid belt. Three worlds but one shared bombardment and a story that may have everything to do with the origins of life.
