Bright Fireballs in the Skies: Catch the Perseids Meteor Shower This Week

You may see as many as 100 meteors per hour if you’re in a place where it’s dark enough.

Skygazers have a lot to look forward to over the next month. A couple of dueling meteor showers are gracing the skies later this month, and they will be joined by perhaps the most popular meteor shower of the year: the Perseids meteor shower.

Perseids are known for their bright fireballs and plentiful meteors. The show started on July 17, and will run through Aug. 23.

The reason the Perseids meteor shower is so popular is twofold. First, it takes place in the summer, so going outside and watching it is less uncomfortable than other large meteor showers like Quadrantids, which takes place in wintery January.

The other reason is that it’s one of the most active meteor showers of the year. During its peak, the meteor shower is known to spit as many as 100 meteors on average, according to the American Meteor Society. These not only include your typical shooting stars, but also a higher chance for fireballs, which are meteors that explode as they enter orbit. Per NASA, fireballs tend to last longer than standard shooting stars and can come in a variety of different colors.

Perseids come to Earth courtesy of the 109P/Swift-Tuttle comet. Earth’s orbit around the sun brings it through Swift-Tuttle’s tail every year. The comet itself takes 133 years to orbit the sun. Its last perihelion — the point at which it’s the closest to the sun — was in 1992. It won’t be back until the year 2125. Until then, it leaves behind an excellent tail of dust and debris to feed us yearly meteor showers.

How to watch the Perseids meteor shower

The best time to view the Perseids is during its peak, which occurs on the evenings of Aug. 12 and 13. During this time, the shower will produce anywhere from 25 to 100 meteors per hour on average. However, since the shower officially lasts for over a month, you have a chance to see a shooting star on any given evening, provided that you’re far enough away from light pollution.

Thus, if you’re planning on watching this year’s Perseids during their peak, you’ll want to get out of the city and suburbs as far as possible. According to Bill Cooke, lead of NASA’s Meteoroid Environments Office, folks in the city might see one or two meteors from the meteor shower per hour, which is pocket change compared to what those outside city limits might see.

Regardless, once you’ve arrived at wherever you want to watch the meteors, you’ll want to direct your attention to the radiant, or the point at which the meteors will appear to originate. Like all meteors, Perseids are named after the constellation from which they appear. In this case, it’s Perseus.

Per Stellarium’s free sky map, Perseus will rise from the northeastern horizon across the continental US on the evenings of Aug. 12 and 13. It’ll then rise into the eastern sky, where it’ll remain until after sunrise. So, in short, point yourself due east and you should be OK. Binoculars may help, but we recommend against telescopes since they’ll restrict your view of the sky to a very small portion, which may hinder your meteor-sighting efforts.

The American Meteor Society also notes that the moon may give viewers some difficulty. Perseids’ peak occurs just three days after August’s full moon, so the moon will still be mostly full. Thus, it is highly probable that light pollution from the moon may reduce the number of visible meteors by a hefty margin, depending on how things go.

Cloudflare CEO Apologizes for ‘Unacceptable’ Outage and Explains What Went Wrong

For several hours Tuesday, a significant portion of the internet was unavailable in Cloudflare’s worst outage since 2019.

The Cloudflare outage on Tuesday that disrupted access to many websites and services — including OpenAI, Spotify, X, Grindr, Letterboxd and Canva — was the company’s worst outage since 2019, CEO Matthew Prince says.

Other disruptions have centered on specific network features, Prince wrote in a blog post. «But in the last 6+ years we’ve not had another outage that has caused the majority of core traffic to stop flowing through our network.»

Cloudflare is a cloud services and cybersecurity company based in San Francisco that is used by approximately 20% of all websites, according to W3Techs. It’s one of a handful of services, along with Amazon Web Services, CrowdStrike and Fastly (all of which have experienced major outages in the past few years) that you might never have heard of, but that provide essential internet infrastructure.

The bulk of sites and services impacted by Tuesday’s outage, which began around 3:30 a.m. PT, seemed to recover within just over three hours. By the end of the day, everything had returned to normal, and Cloudflare set about explaining what went wrong. Here’s what you need to know.

What caused the Cloudflare outage?

Cloudflare was keen to emphasize that the outage was not caused either directly or indirectly by a cyberattack. At first the company did suspect it might have originated from a «hyper-scale DDoS attack,» Prince said in his blog post. But it turned out that the outage resulted from an internal software failure.

A change in one of Cloudflare’s databases generated a larger-than-expected feature file, which was too big for the company’s software to run, said Prince. This caused the software to fail.

Once Cloudflare identified the problem, it was able to replace the problematic file with an earlier version and get most traffic flowing normally again by 6:30 a.m. PT.

«We are sorry for the impact to our customers and to the Internet in general,» said Prince. «Given Cloudflare’s importance in the Internet ecosystem any outage of any of our systems is unacceptable. That there was a period of time where our network was not able to route traffic is deeply painful to every member of our team. We know we let you down today.»

Which sites and services were impacted?

Cloudflare has a massive range of clients across the internet, ranging from websites that are household names to smaller services you might not have heard of. Due to its size, when it went down, it took many of those sites and services with it.

Among those affected by the outage was Downdetector, which is where most people go to report problems when services are offline. (Downdetector is owned by the same parent company as CNET, Ziff Davis.)

Once it got back up and running, Downdetector said that it received over 2.1 million reports during the outage period. Over 435,000 of these came from the US, with the UK, Japan and Germany appearing to be the countries that were next most affected.

Most of the reports pertained to Cloudflare, but other affected companies also received a significant number of reports. They include X (320,549 reports), League of Legends (130,260 reports), OpenAI (81,077 reports), Spotify (93,377 reports) and Grindr (25,031 reports).

How did the outage unfold?

Cloudflare first acknowledged the outage at 3:48 a.m. PT. The company issued a statement on its system status page saying that it was aware of the problem.

«Cloudflare is aware of, and investigating an issue which impacts multiple customers: Widespread 500 errors, Cloudflare Dashboard and API also failing,» it said. «We are working to understand the full impact and mitigate this problem. More updates to follow shortly.»

At 5:09 a.m. PT, the company said the issue had been identified and a fix was being implemented. In the subsequent hours, errors began to drop and services gradually came back online.

Cloudflare added at 9:14 a.m. PT that most services had returned to normal. «A full post-incident investigation and details about the incident will be made available asap,» it said.

Is the internet stable and reliable?

The Cloudflare outage comes just one month after Amazon Web Services went down, causing havoc across the internet. The AWS outage affected sites including Reddit, Snapchat, Roblox and Fortnite, sparking many to ask whether having such huge swaths of the internet reliant on a few centralized services is sensible or safe.

«The Cloudflare outage is not explicitly caused or linked to the AWS or Azure outages last month, but like those failures, it shows the impact of concentration risk,» said Brent Ellis, principal analyst at Forrester Research. «In this case, the 3 hour 20 minute outage could have direct and indirect losses of around $250 million to $300 million when you consider the cost of down-time and the downstream effects of services like Shopify or Etsy that host the stores for tens to hundreds of thousands of businesses.»

The disruption to services from ChatGPT maker OpenAI in particular highlighted concerns about the growing investment in artificial intelligence and the fragility of the cloud infrastructure that AI relies upon to function every day.

«The most dominant platform did not buckle because of simultaneous queries or the release of a new competitive model, but because of a problem with Cloudflare, a web security and performance provider,» said Sarah Kreps, director of the Tech Policy Institute at Cornell University. «The issue exposes the reality that this multibillion, even trillion-dollar investment in AI is only as reliable as its least scrutinized third-party infrastructure.»
