Scientists simulated what would happen if a medium-size asteroid were to strike Earth. One of those space rocks, asteroid ...
近日,科学家们在对小行星Bennu的样本进行分析时,发现了生命所必需的有机化合物和矿物质。这一研究成果不仅让人惊叹于太空的复杂性,也为"生命起源"这一重要科学问题提供了新的思考。Bennu被认为是在地球历史早期为地球提供生命组成部分的关键小行星。
Scientists recently completed computer simulations of what would happen to Earth if it were impacted by an asteroid with a ...
Bennu was the target for NASA's OSIRIS-REx asteroid sampling mission, which touched down briefly on the space rock in October 2020 to gather over 4 ounces of material, and then brought that sample ...
NASA 的OSIRIS-REx 任务发现了小行星贝努(Bennu)与地球上的苏尔斯湖(Searles Lake)之间的宇宙联系。两者都含有咸水蒸发形成的矿物质,这暗示着贝努的母体曾经拥有液态水库。
在未来的日子里,地球或将面临一场可怕的危机。根据最新的研究,近地小行星Bennu如果与地球相撞,可能会造成极其严重的全球破坏。尽管Bennu的大小仅是当年造成恐龙灭绝的小行星的一小部分,但其潜在的威胁不容小觑。天文学家估计,Bennu将在2182年9 ...
NASA 的OSIRIS-REx 任务从小行星贝努(Bennu)上采集了样本、 揭示了与生命有关的重要分子,包括氨基酸和DNA和RNA中的核碱基。 氨和甲醛的存在表明在太空中形成复杂分子的条件已经成熟。 在这一帧视频中,杰森-德沃金(Jason ...
NASA’s OSIRIS-REx mission returned from space with a sample of an asteroid named Bennu and scientists got to dive into a tale ...
Researchers are unlocking secrets of our solar system by analyzing asteroid Bennu samples, some of the most pristine ever ...
The potentially hazardous asteroid Bennu probably won't hit Earth. But this study shows the damage a space rock of its size could do.
“贝努(Bennu)”在2182年与地球相撞的几率为2700分之一,导致全球冬季和干旱。在2182年9月24日,一颗相对较大的太空岩石有0.037%的几率撞击地球表面。尽管撞击的可能性很小,但“贝努(Bennu)”仍然是我们太阳系中已知的最具潜在危险 ...
NASA’s OSIRIS-REx mission delivered samples from asteroid Bennu, revealing crucial molecules linked to life, including amino ...
