Strange hexagonal diamonds may have been ejected into space around 4.5 billion years ago when a dwarf planet collided with a large asteroid. The hexagonal diamonds, also known as lonsdaleite, were discovered in a rare class of meteorites that could have come from the mantle of a dwarf planet, according to new research. Lonsdaleite, like graphite, charcoal, and diamond, is a structural form of carbon. Whereas diamond's carbon atoms are arranged in a cubic shape, lonsdaleite's carbon atoms are arranged in hexagons. "This study proves categorically that lonsdaleite exists in nature," said Dougal McCulloch, a microscopist at Australia's RMIT University,

The James Webb Space Telescope and the Hubble Space Telescope, two of NASA's Great Observatories, have captured images of a unique NASA experiment designed to intentionally smash a spacecraft into a small asteroid in the world's first-ever in-space test for planetary defense. These observations of NASA's Double Asteroid Redirection Test (DART) impact are the first time Webb and Hubble have observed the same celestial target at the same time. DART intentionally collided with Dimorphos, the asteroid moonlet in Didymos' double-asteroid system, on September 26, 2022, at 7:14 p.m. EDT. It was the world's first test of the kinetic impact mitigation

Using the Keck Observatory, astronomers from the Radboud University in the Netherlands and elsewhere have conducted spectroscopic observations of a young massive cluster known as NGC 1569-B. Results of the observational campaign, published September 23 on the arXiv pre-print server, yield important insights into the chemical composition of this cluster. In general, young massive clusters (YMCs) are dense aggregates of young stars that form the fundamental building blocks of galaxies. Studying their chemical composition could provide essential information regarding stellar populations. Estimated to be 15–25 million years old, NGC 1569-B is a YMC in the dwarf irregular galaxy NGC 1569,

A group of scientists from Université Clermont-Auvergne, working with a partner from Universität Bayreuth, has found proof that suggests the world's creation changed over the long haul during its initial years by means of collisional disintegration. In their paper distributed in the diary Science, the group describes their investigation of the measures of samarium and neodymium in shooting stars and what it showed them about the cycles that prompted the ongoing cosmetics of the Earth. The College of Bristol has distributed a Viewpoint piece in a similar diary issue illustrating hypotheses in regards to the development of the Earth and

Late exoplanet investigation has zeroed in on the disclosure of mildly rough planets like the Earth, which are many times called tenable planets. The majority of the new missions are focusing on stars cooler than the sun. Such stars are known as red-small people or M-type stars, which are various in the sun-based area. Moderate insolation and a sufficient measure of seawater are vital for a planet to keep a calm environment. Past planet arrangement models, in any case, foresee that the event pace of planets fulfilling such circumstances around M-type stars is small. New recreations led by Tadahiro Kimura,
