Department of Defense (DoD) sensors through the light that it emitted as it burned up in the Earth’s atmosphere off of the coast of Papua New Guinea in 2014 [1]. The material strength of IM1 appears to be higher than all other 272 meteors in the CNEOS catalog [2]. A forthcoming ...
ASTEROID 2024 YR4 IS NO LONGER A THREAT:Christmas 2032 might be Merry, after all. New observations of "city-killer" asteroid 2024 YR4 have ruled out an impact with Earth on Dec. 22, 2032. According to JPL, theodds of a strikehave plummeted to a miniscule 0.002%--safer thancrossing th...
Meteor-2 carried three types of optic-mechanical TV sensors operating in visible part of spectrum, as well as in infra-red, capable of providing global image of cloud cover and the Earth surface below day and night. Additionally, the satellite was equipped with radiometric sensors registering ...

Once you have found your viewing spot, lie down on the ground and look at the sky. You can use our Interactive Meteor Shower Sky Map or the table above to find the direction of the radiant; the higher the radiant is above the horizon, the more meteors you are likely to see. ...
Map: Bob King, Source: Stellarium The Quadrantid meteor shower, named for the obsolete constellation Quadran Muralis, will appear to stream from a point in the sky called the radiant (yellow star), located below the end of the Big Dipper’s handle and across from the bright, orange-red ...
But visible light detection is limiting, and knowing that meteors leave a trail of ions means radio detection is possible. That’s what’s behind this attempt to map meteor trails using broadcast signals, which so far hasn’t yielded great results. Passing jet’s Doppler signature The fact ...
In general, the Earth encounters richer meteoric activity during the second half of the year. And you're more likely to see twice as many meteors per hour in the predawn hours as compared to the evening hours. This is due to the fact that during the pre-midnight hours we are on the ...
