Fireballs

Fireball 3

Meteor fireball over northern Italy on January 5

mmmmmmmmm
It appeared at a height of 71 kilometers from the earth 's surface, reaching a speed of 17 kilometers per second and finally reaching the considerable altitude of 37 kilometres.

These are some of the numbers shared by the experts of Prisma (the first Italian network for the systematic surveillance of meteors and atmosphere) regarding the passage of a brilliant fireball over the Venice area yesterday evening, at around 18:36. ( Article here ).

Here are the images of the fabulous show.


Comet 2

Possible naked-eye comet will visit Earth for first time in 50,000-years

The comet C/2022 E3 (ZTF) could be bright enough to be spotted with the naked eye as it passes the sun and Earth at the end of the first month of 2023.

At the start of 2023 Earth will be visited by a newly discovered comet that may just be bright enough to be spotted with the naked eye.

The comet, named C/2022 E3 (ZTF), is currently passing through the inner solar system. It will make its closest approach to the sun, or perihelion, on Jan. 12, and will then whip past Earth making its closest passage of our planet, its perigee, between Feb. 1 and Feb. 2.

If the comet continues to brighten as it currently is, it could be visible in dark skies with the naked eye. This is difficult to predict for comets, but even if C/2022 E3 (ZTF) does fade it should still be visible with binoculars or a telescope for a number of days around its close approach.

According to NASA, observers in the Northern Hemisphere will be able to find the comet in the morning sky, as it moves in the direction of the northwest during January. C/2022 E3 (ZTF) will become visible for observers in the Southern Hemisphere in early February 2023.

Storm Corrie touches down in Scheveningen, a district of The Hague, Netherlands, on January 31st, 2022.
There was a stormy start to 2022 as at least four storms battered the Netherlands throughout the end of January and February. During the year, the country also saw snowfall, floods, sinkholes, tornadoes and fireballs. Below are some highlights from extreme weather events in the Netherlands in 2022.

This asteroid impact simulator lets you destroy the world

A web app from Neal.Fun is a choose-your-own-adventure for planetary annihilation.

I aimed a 1,500-foot iron asteroid traveling at 38,000 miles per hour with a 45-degree impact angle at Gizmodo’s office in Midtown, Manhattan.
Hundreds of thousands of asteroids lurk in our solar system, and while space agencies track many of them, there's always the chance that one will suddenly appear on a collision course with Earth. A new app on the website Neal.fun demonstrates what could happen if one smacked into any part of the planet.

Neal Agarwal developed Asteroid Simulator to show the potentially extreme local effects of different kinds of asteroids. The first step is to pick your asteroid, with choices of iron, stone, carbon, and gold, or even an icy comet. The asteroid's diameter can be set up to 1 mile (1.6 kilometers); its speed can be anywhere from 1,000 to 250,000 miles per hour; and the impact angle can be set up to 90 degrees. Once you select a strike location on a global map, prepare for chaos.

HAARP to bounce signal off asteroid in NASA experiment

With temperatures falling to 40 degrees below zero, a frosty landscape surrounds antennas at the High-frequency Active Auroral Research Program site in Gakona, Alaska, on Dec. 20, 2022. HAARP conducted a run-through on that date to prepare for the Dec. 27 asteroid bounce experiment.
An experiment to bounce a radio signal off an asteroid on Dec. 27 will serve as a test for probing a larger asteroid that in 2029 will pass closer to Earth than the many geostationary satellites that orbit our planet.

The High-frequency Active Auroral Research Program research site in Gakona will transmit radio signals to asteroid 2010 XC15, which could be about 500 feet across. The University of New Mexico Long Wavelength Array near Socorro, New Mexico, and the Owens Valley Radio Observatory Long Wavelength Array near Bishop, California, will receive the signal.

This will be the first use of HAARP to probe an asteroid.

"What's new and what we are trying to do is probe asteroid interiors with long wavelength radars and radio telescopes from the ground," said Mark Haynes, lead investigator on the project and a radar systems engineer at NASA's Jet Propulsion Laboratory in Southern California. "Longer wavelengths can penetrate the interior of an object much better than the radio wavelengths used for communication."

Knowing more about an asteroid's interior, especially of an asteroid large enough to cause major damage on Earth, is important for determining how to defend against it.

"If you know the distribution of mass, you can make an impactor more effective, because you'll know where to hit the asteroid a little better," Haynes said.

Many programs exist to quickly detect asteroids, determine their orbit and shape and image their surface, either with optical telescopes or the planetary radar of the Deep Space Network, NASA's network of large and highly sensitive radio antennas in California, Spain and Australia.
