The web is alight with footage of a meteor that sped by means of the evening skies over Portugal and Spain, lighting up the skies as a blue-green fireball.
The meteor was confirmed by European Space Agency (ESA), who caught the fireball with its cameras in Cáceres, Spain, at 6:46 p.m. EDT (22:46 UTC) on Saturday (Might 18). The ESA confirmed that the fireball was a chunk of a comet that rocketed over Spain and Portugal, touring at round 100,000 miles per hour, or about 65 instances as quick as the highest velocity of a Lockheed Martin F-16 jet fighter. The ESA added that the meteor possible burned up over the Atlantic Ocean at an altitude of round 38 miles (60 kilometers) over Earth.
Social media customers took to X, Fb, and Reddit by the 1000’s to debate the bright fireball and share beautiful pictures and movies.
Associated: Meteorites from Asteroid 2024 Bx1, which just hit Earth, may be super-rare space rocks
The ESA wrote on its X feed that “ESA’s fireball digital camera in Cáceres, Spain, noticed this beautiful meteor final evening! Our Planetary Defence Workplace is at the moment analyzing the scale and trajectory of the item to evaluate the possibility that any materials made it to the floor.”

X user Colin Rugg shared beautiful footage of the meteor on his feed, writing: “That is insane. Early stories declare that the blue flash may very well be seen darting by means of the evening sky for lots of of kilometers. In the mean time, it has not been confirmed if it hit the Earth’s floor nevertheless some stories say it could have fallen close to the city of Castro Daire. Different stories say it was nearer to Pinheiro.”

Information and media group Nova Portugal additionally shared footage of the fireball taken from numerous places.
“A meteorite lit up the sky of Portugal with a glowing blue final night to the shock of the inhabitants who had been outdoors on the time of its passage. 1000’s of Portuguese individuals shared their reactions to the occasion on social networks.”

“Shooting stars” like this are items of fabric that break free from bigger our bodies like asteroids, comets, the moon, and even different planets and enter Earth’s environment at excessive speeds. The friction these fragments known as meteoroids (the identify given to them when they’re in area) encounter causes them to glow brightly, turning into meteors for just a few temporary seconds as they streak by means of the environment, making a glowing path.
Round 90% to 95% of interstellar matter that makes its approach to Earth this manner would not final lengthy sufficient to make it to the bottom. If a meteoroid does make it to the bottom, it’s often within the type of mud or very small particles and it’s known as a meteorite.
Simply as totally different chemical parts are used to generate fireworks of various colours, the colour of this fireball signifies its chemical composition.
The intense blue/inexperienced flash of the fireball signifies the burning of magnesium. One sort of meteorite identified to bear magnesium are the “pallasites,” which include massive olive-green crystals which are a type of magnesium-iron silicate known as olivine.
Although the origins of pallasites are considerably mysterious, scientists suppose they may kind when asteroids soften, with denser materials sinking to their cores. Pallasites might come from the boundaries between an asteroid’s metallic core and its silicate, olivine-rich mantle.
If that is so, then pallasites might train scientists an important deal about how rocky planets like Earth formed in the solar system about 4.5 billion years in the past.
In fact, this meteorite hasn’t but been confirmed as pallasite, and scientists do not know if any of it truly reached the bottom, although the ESA says that the potential of that is slim at finest.
There’s little doubt that the eruption of this fireball over Portugal and Spain goes to maintain meteorite hunters busy for not less than the approaching days as they seek for fragments that would have reached terra firma.
