#NYT 📆 Jan. 26, 2023 The #asteroid about the size of a truck 🚚 (10m across) did not hit #Earth 🌎 but was one of the #closest #approaches ever by such an object, hurtling past Earth at just 2,200 miles above its surface. It was #unknown to #NASA, or anyone, until last Saturday https://www.nytimes.com/2023/01/26/science/astronomy-asteroids-2023bu.html
The object that excavated the #Barringer #crater was about 50 m across https://en.wikipedia.org/wiki/Meteor_Crater

#Gemini #North #telescope on #Hawaii reveals #first #dormant, #stellarmass #blackhole in our #cosmic #backyard.
#Astronomers have discovered the #closest known black hole to #Earth. This is the first unambiguous detection of a dormant stellar-mass black hole in the #MilkyWay. Its close proximity to Earth, a mere #1600 #lightyears away, offers an intriguing target of study to advance our understanding of the evolution of #binary systems
