Fireball 5

Huge meteor fireball explodes over Argentina on July 7

fireball
Both in Mendoza and in the vicinity of Santiago de Chile, a huge flash could be seen in the sky, a "fireball" that was heading for the Andes Mountains around 5:30 in the morning.

Thanks to a video shared by a user, you can see the amazing phenomenon that appears above the lights of the city and the dark night and vanishes between the mountains. A similar event was also reported in New Zealand and Mexico.

According to what witnesses told, the fireball sounded like thunder once it entered the atmosphere, so several people from Maipú, San Martín, Godoy Cruz, Tunuyán, Lavalle and Luján de Cuyo, in Mendoza, woke up startled. at dawn.

Comet C/2017 K2 might strike the moon!
A giant comet C/2017 K2 is likely to make a close approach to Earth this month on July 14, 2022. The comet was first discovered in 2017 by Nasa's Hubble Space Telescope hurtling somewhere between Saturn and Uranus. Now it is approaching Earth and the inner solar system at a distance of around 270 million km. Though it does not pose any threat to our planet, an animation video published by specialist Hazegrayart last week shows the comet coming close to our planet and then getting pulled toward the Moon, and impacting it with its full force. However, nothing can be confirmed as yet.

Meanwhile, skywatchers will be able to see the comet by using a small telescope. C/2017 K2 (PanSTARRS) has been traveling from the Oort cloud to the inner solar system and it will be so active and bright that it could be detectable from Earth. The comet relies on energy from the Sun to heat up gasses. Here's all you need to know about Oort cloud and how to spot Comet C/2017 K2 from earth.

Daytime meteor fireball over New Zealand on July 7

New Zealanders across the North Island have reported rumbling, crackling sounds, a fireball and a huge flash of light streaking across the sky on Thursday afternoon, in what scientists believe was likely a meteor.

Local media outlets and social media were flooded with reports and queries about the sight, with some witnesses describing rumbles, bangs, a crackling sound in their ears, hair standing on end, rattling windows or a streak or explosion of light, followed by a smoke trail.

Seismologists at Geonet picked up a presumed sound wave from the object, and weather scientists for Metservice believe they picked up the object - or its smoke trail - on radar.

Plumber Curtis Powell captured the phenomenon on his dashcam while driving north of Shannon at 1.39pm on Thursday.

Tenoumer crater, Mauritania

Deep within the Sahara Desert lies one of the best-preserved craters on Earth. On Asteroid Day, the Copernicus Sentinel-2 mission takes us over the almost-perfectly circular Tenoumer Crater in Mauritania.

Tenoumer Crater, visible in the centre of the image, is 1.9 km wide. The rims of the crater rise some 110 m high above the base, but the bottom of the crater is covered with approximately 200 to 300 m thick layer of sediments.

It was long debated whether the crater was formed by a volcano or meteorite. Scattered rocks around the crater, similar to basalt, created the impression of an ancient volcano. Yet a closer exanimation of the structure revealed the crater's hardened 'lava' was actually rock that had melted by a meteorite impact.

The crater sits in a vast plain of rocks that are so ancient they were deposited hundreds of millions of years before the first dinosaurs walked Earth. Even though it resides in ancient rock, Tenoumer is much younger, ranging in age between 10 000 and 30 000 years old.

Fireball 2

Meteor fireball over south of Spain (June 30)

fireball
This bolide was spotted over Spain on June 30, at 23:58 local time (equivalent to 21:58 universal time). The event was generated by a rock (a meteoroid) from a comet that hit the atmosphere at about 102,000 km/h. The fireball overflew southern Spain. It began at an altitude of about 103 km over the locality of Cacin (province of Granada), moved northwest, and ended at a height of around 65 km over the locality of Baena (province of Córdoba).

This bright meteor was recorded in the framework of the SMART project, operated by the Southwestern Europe Meteor Network (SWEMN) from the meteor-observing stations located at Huelva, La Hita, CAHA, OSN, La Sagra, Sevilla, and El Aljarafe. The event has been analyzed by the principal investigator of the SMART project: Dr. Jose M. Madiedo, from the Institute of Astrophysics of Andalusia (IAA-CSIC).


Comet 2

Two new comets C/2022 J1 & C/2022 L1

CBET 5121 & MPEC 2022-J88 , issued on 2022, May 11, announce the discovery of a comet (magnitude ~18) by A. Maury and G. Attard on images obtained with a 0.28-m f/2.2 Schmidt reflector at San Pedro de Atacama, Chile, on May 5. The new comet has been designated C/2022 J1 (Maury-Attard).

Stacking of 15 luminance-filtered exposures, 60 seconds each, obtained remotely (in poor conditions, high clouds) on 2022, May 6.4 from X02 (Telescope Live, Chile) through a 0.61-m f/6.5 astrograph + CCD, shows that this object is a comet with a diffuse coma of size about 12" and magnitude of 18.3-18.9 in an aperture radius of 5".5 (Observers E. Bryssinck, M. Rocchetto, E. Guido, M. Fulle, G. Milani, G. Savini, A. Valvasori).
