Meteor Network solves Thursday’s fireball mystery

Folks in parts of Scotland and Northern Ireland were treated to an unexpected light show on Wednesday evening when a mysterious object streaked across the night sky for nearly half a minute.

Many who caught the spectacle on camera quickly shared the footage on social media, with the footage clearly showing a bright light flying overhead.

The U.K. Meteor Network received reports from hundreds of people who had spotted the mysterious object. After analyzing numerous videos and taking a look at the available data, the Meteor Network initially concluded that the streak of light was likely caused by space debris burning up as it entered Earth’s atmosphere at high speed.

Speculation centered on SpaceX, which was known to be de-orbiting two of its Starlink satellites at around that time.

Hey @elonmusk is this one of yours?

But then the Meteor Network tweeted: “We have checked the Starlink de-orbit and it would not have come anywhere near the U.K. At this point we cannot find any known space junk or satellite de-orbit that could account for this fireball. We are looking at the data again.”

After conducting further analysis of the unusual event, and assisted by Canada-based meteor physics postdoctoral researcher Denis Vida,  the Meteor Network later confirmed that the bright object was a meteor after all, and not a piece of space junk.

“The final analysis is in!” the network said later on Wednesday. “The fireball over [Northern Ireland] and Scotland last night was definitely a meteor. The fireball observed yesterday (Sept 14, 20:59:40 UT) above the U.K. lasted over 20 seconds and traveled NW, passing directly over Belfast.”

OK. The final analysis is in! The fireball over NI and Scotland last night was definitely a meteor. The fireball observed yesterday (Sept 14, 20:59:40 UT) above the UK lasted over 20 seconds and traveled NW, passing directly over Belfast. 1/4

It suggested that any remains of the small rock likely ended up in the North Atlantic Ocean around 50-100 kilometers (31-62 miles) west of the Isle of Islay, in a spot some 192 kilometers (120 miles) northwest of Belfast.

“It came on an asteroidal orbit and entered the atmosphere at 14.2 kilometers per second [8.8 miles per second],” the Meteor Network confirmed.

“The observed portion of the trajectory covered over 300 km [186 miles],” it said, adding: “If any meteorites did fall, they ended up in the ocean.”

Events like this are usually nothing to worry about, with NASA, for example, far more focused on much larger asteroids that could cause problems for Earth in the future. With that in mind, the American space agency is currently conducting a fascinating mission that will test technology designed to defend our planet against hazardous space rocks.

There could be a brand new meteor shower visible on Monday
This infrared image from NASA’s Spitzer Space Telescope shows the broken Comet 73P/Schwassman-Wachmann 3 skimming along a trail of debris left during its multiple trips around the sun. The flame-like objects are the comet’s fragments and their tails, while the dusty comet trail is the line bridging the fragments.

This Memorial Day weekend there's a chance you could view a special astronomical event: A never-before-seen meteor shower called the Tau Herculids.

The new meteor shower could be visible on the night of May 30 into May 31 in North America, which is an exciting possibility. However, it's hard to predict if meteors will actually be visible or not, as it is what NASA calls a "hit or miss" event.

How to watch the spectacular Quadrantids meteor shower this week
A finder chart depicting the location of the radiant of the Quadrantids meteor shower, from Astronomy Now magazine.

This week will see the peak of the Quadrantids meteor shower, which could be the most spectacular meteor shower of 2022. There will be up to 50 meters or more visible per hour when the shower is at its peak. So if you fancy a night of stargazing, we've got the details on how to watch.

The shower will peak between January 2 and January 4, and should be visible across the northern hemisphere. Meteor showers like the Quadrantids happen when Earth passes through clouds of debris in its orbit, and small particles of this debris enter Earth's atmosphere. The particles for the shower this week will be traveling at tremendous speeds of around 25 miles per second and will burn up in the atmosphere. As they burn up they glow, creating a streak of light across the sky.

Mystery of a strange, mirrored double galaxy solved using Hubble data
hubble mirrored galaxy stsci 01ffjer4zps9v9yfpbhrb7p5wj 1

When telescopes like Hubble peer out into the cosmos, they can sometimes sneak a view of very distant objects using a phenomenon called gravitational lensing. This is where a massive object like a galaxy passes between a distant object and Earth, and the gravity of this intermediate object warps spacetime and acts as a magnifying glass. This allows astronomers to glimpse objects which would otherwise be too faint and far away to be visible.

But sometimes these phenomena result in strange outcomes, like an oddity spotted by Hubble in 2013 which appeared to be two objects that were perfect mirror images of each other.
