#NASA每日一图# 2022-10-17 APOD:【X-Ray Rings Around a Gamma Ray Burst】
Why would x-ray rings appear around a gamma-ray burst? The surprising answer has little to do with the explosion itself but rather with light reflected off areas of dust-laden gas in our own Milky Way Galaxy. GRB 221009A was a tremendous explosion -- a very bright gamma-ray burst (GRB) that occurred far across the universe with radiation just arriving in our Solar System last week. Since GRBs can also emit copious amounts of x-rays, a bright flash of x-rays arrived nearly simultaneously with the gamma-radiation. In this case, the X-rays also bounced off regions high in dust right here in our Milky Way Galaxy, creating the unusual reflections. The greater the angle between reflecting Milky Way dust and the GRB, the greater the radius of the X-ray rings, and, typically, the longer it takes for these light-echoes to arrive.

在近日于菲律宾举办的新品发布会上，影驰（GALAX）不仅展示了该公司的最新RTX 40产品设计、还意外漏出了在某个角落的“RTX 4050”包装盒。
本场发布会的主角，有包括近期打破纪录的GeForce RTX 4090 SG 旗舰 SKU 。但某个展台底下紧挨着 GeForce RTX 4080 的神秘“GeForce RTX 4050”包装盒，却更加吸引网友们的眼球。
WCCFTech 推测，厂商可能很早了就打印了一系列未来产品的包装盒，然后某个员工不小心将它搬到了会场，不过何时推出就不知道了。
之前就有人爆料称，实际上NVIDIA已经开始测试AD106和AD107两套核心的显卡产品，预计分别对应RTX 4060和RTX 4050。
至于性能嘛，RTX 4060/4050实力也不容小觑，接近RTX 3080或者RTX 3070 Ti完全可以期待下。
如果你想买40系列显卡，那么这款可能是最实惠的选择。#亿点曝光计划#
