Meteor Shower Season Heats Up With Daytime Sextantid Show

Earth is set to pass through a series of dusty clouds of space debris from Halley’s Comet and others that promise to light up night skies.

August’s Perseid meteor shower may be the most well known of the year, but it’s the last quarter of the year that brings the most shooting-star and fireball action to night skies.

As of this week, both the Orionid and Southern Taurid meteor showers are active and the little known Daytime Sextantid shower is peaking now.

The Sextantids are often ignored for obvious reasons because they’re oriented in such a way that they’re typically impacting our atmosphere during the day and therefore washed out by sunlight. However lucky observers may be able to catch one in the hour before dawn, when they can sometimes be seen shooting straight upward from the eastern horizon. This unusual shower peaks Wednesday, making Thursday morning the ideal time to go looking for the rare upward-shooting meteor.

Fortunately, the pre-dawn hours are also a good time to look for the other meteor showers active now.

While the Orionids aren’t set to peak until around Oct. 20, they still add some shooting stars to each night’s sky until then. The Taurids, on the other hand, don’t have a very defined peak and are forecast to be visible at a rate of around two per hour over the next several weeks.

Adding to the celestial drama is the Taurids’ reputation for delivering a number of bright fireballs streaking through the sky.

«In 2022, the Earth passed through a swarm of Taurid fireballs,» writes Bob Lunsford for the American Meteor Society. «This year we are further from this swarm but will still encounter some fireball activity.»

The Taurids can be traced to debris from the comet 2P/Encke, while the Orionids are connected to the leavings of the famed Halley’s Comet, which visits the inner solar system only about every 75 years. The celebrity snowball won’t be back until 2061.

Two distinct clouds from Halley’s Comet are responsible for both the Orionids each October and the Eta Aquariids meteor shower in May.

How to see the celestial show

When the Orionids peak between Oct 20 and 22, the conditions should be nearly perfect, especially with the moonless sky on the morning of the 22nd in the hours just before dawn. Most nights, the area near the constellation of Orion the Hunter where the Orionids appear to radiate from will be highest in the sky around 2 a.m. But it may be possible to see the meteors anytime between midnight and dawn. The closer you get to dawn, the better your chance of seeing one of those vertical Sextantids as well.

The Orionids are known for zipping through the sky at relatively high speed and often leaving long trains that can linger for a second or two.

During those peak mornings, the number of Orionid meteors will suddenly increase to between 10 and 20 per hour, but sometimes Earth passes through a particularly dense pocket of debris and those rates shoot up to 50 to 70, rivaling the Perseids.

While it’s worth marking the Orionids’ peak on your calendar, you might be able to catch a handful of meteors and a fireball on any given night over the next several weeks.

If you have at least an hour free on a night with clear skies and a location away from light pollution, all you need to do is find an area with a broad view of the night sky. Allow at least 15 minutes for your eyes to adjust to the darkness and then just relax, lie back and watch.

You’ll hear seasoned skywatchers talking about orienting yourself to face the radiant of a particular meteor shower. The radiant is the section of the sky from which certain meteors will appear to radiate outward. Meteor showers are usually named for a constellation within that radiant, so the Orionids are named for Orion.

If you can locate Orion in the sky and orient yourself in that direction, it might boost your viewing experience slightly. But the reality is that most amateurs won’t notice a difference. It’s far more important to have dark skies away from light pollution and the widest view of the sky possible. While meteors might originate from a certain radiant, they go all over the sky from that point, so it really doesn’t matter much which way you face.

Plus, there are more than Orionids up there on most nights. There are also the aforementioned Taurids, smaller showers like the Anthelion and even sporadic meteors that aren’t part of defined showers.

So just plan for at least an hour outside, preferably between midnight and dawn, for the best chance to make it through lulls in activity and spotting a few meteors. Be sure to bring all you need to be comfortable that long: Blankets, snacks and drinks are a good idea. Good luck!

Google’s AI Mode Is Getting New Agentic Features for Restaurant Reservations and More

AI Mode can now do most of the work to find dinner reservations for you.

Google’s AI Mode is getting new agentic capabilities and expanding to 180 new countries and territories around the world, Google announced Thursday. AI Mode allows you to ask questions directly to Google and it’ll kick off a series of searches on your behalf. From there, it will surface relevant information to your query without the need to do any of the deep research yourself. It changes the way you search for things online, and it’s getting even smarter with this latest rollout.

Powered by DeepMind’s Project Mariner, the latest additions bring us further into the agentic AI future we’ve been promised for some time, directly from a search box. Instead of just finding things for you, AI Mode can now do things for you, like finding dinner reservations, flights or concert tickets. The update also brings personalized recommendations and link-sharing capabilities for easier collaboration with friends and family.

Most of the new features are either limited to premium AI subscribers and tucked behind an experiment in Google Labs, but it might not take long before they’re a standard part of your future search experience.

Google did not immediately respond to CNET’s request for further comment.

Restaurant recommendations

Instead of searching for restaurant reservations and then clicking on a specific website to make a reservation, AI Mode surfaces everything you need to complete the action right there. Since it’s contextually aware, you can add specificities to your query that a typical Google search wouldn’t handle well.

You can add the type of cuisine, number of people, time and location to a single query, and AI Mode will get to work and display real-time restaurant reservation time slots to choose from.

Google says it’s partnered with OpenTable, Resy, Tock, Ticketmaster and several other companies to make finding and doing what you want easier, since you won’t have to put in the legwork yourself.

This feature is currently rolling out to Google AI Ultra subscribers in the US who have enabled the specific experiment in Labs.

Personalized recommendations

Another experiment that’s currently available in the US (that also needs to be enabled in Labs) is personalized recommendations. Google says it’s starting with dining-related recommendations, which implies more options will be on the way in the future.

The experiment will use your past conversations with AI Mode, places you’ve interacted with on Search and Maps to provide suggestions tailored specifically to you.

Share AI Mode links with others for collaboration

If you’re planning a vacation or a party, you can now share your research directly with others with a new link-sharing feature built into AI Mode. People who interact with the link will be sent to the last response sent by AI Mode and can continue the conversation on their own to do more exploration on the topic. The original sender of the links can manage them and delete them at any time.

IPhone or Android, Here’s How to Finally Escape That Endless Group Chat

Done with a group chat? Here’s how to ghost it on any service.

One reason people prefer group chats in Apple’s iMessage or RCS texting is the extra control and security these platforms provide. If everyone in your group is using iPhones, or if you’re on Android chatting through RCS, you’ll get features like typing indicators, high-quality media sharing, and the option to mute or leave a conversation when you need fewer notifications.

The biggest advantage is privacy. Both iMessage and RCS group chats offer end-to-end encryption, so your conversations stay secure. The only time that doesn’t apply is when a thread includes a mix of iPhone and Android users, which limits encryption support.

Knowing these differences can help you manage your chats more effectively, whether you’re keeping up with friends, planning events, or just looking for a little more control over your notifications.

And with RCS support with iOS 18, group chats that include a mix of iPhone and Android participants have more features than ever — but it’s not at the level you’ll experience when a conversation is fully on iMessage or Google Messages. «Green bubble chats» from an iPhone to an Android phone can now include typing indicators, higher-quality media and easier group chats.

However, RCS conversations between the iPhone and Android phones don’t include encryption now, but it should be added in a future update. This will hopefully give these conversations a similar level of privacy that we expect when using chat services like iMessage, WhatsApp or Signal.

Regardless of how you’re in a group chat with others, you can leave a chat. Here are the steps to leave any conversation from your phone’s texting app, regardless of whether it’s happening on iMessage, RCS or as a mixed MMS chat.

Don’t miss any of CNET’s unbiased tech content and lab-based reviews. Add us as a preferred Google source on Chrome.

Leaving group chats on an iPhone

You can leave group conversations on your iPhone in two ways. You can either mute a chat,which keeps you in a conversation but you no longer receive notifications about it, or you can outright leave and no longer have access to the chat.

On an iPhone, open Messages and go to the chat thread you want to leave. At the top of the screen are conversation controls, a group of icons with the participants. Tap this to open a pop-up menu. As long as your conversation has four or more participants, iOS gives you the ability to tap Leave this Conversation with red text. If your chat has three or fewer participants, though, the option is grayed out, but you can tap Hide Alerts to prevent the conversation from notifying you further. Tapping Hide Alerts also allows you to mute a conversation, letting you keep access to a chat without necessarily leaving it. These steps apply to both iMessage conversations and to those over RCS.

Hide and block MMS chats on an iPhone

Although you can’t officially leave MMS group chats, you can hide or block the conversation. It’s not as good as outright leaving a conversation (other participants will still see you as in it), but you at least have no personal evidence of the conversation continuing.

On an iPhone, visit the group chat and tap the conversation controls. Instead of seeing Leave this conversation, you will see the option to Delete and Block this conversation. If you’d rather just mute the conversation instead of deleting and blocking it, you can hit Hide Alerts to mute it.

Leave group chats on an Android phone

On an Android phone using Google Messages, visit the chat thread you want to leave. Tap the conversation’s name to bring up the Group Details menu. Within this menu is the Leave Group button. Unlike with iMessage, you can leave chats with as few as three participants.

If you want to just mute notifications, tap Notifications on the Group Details screen to bring up a window with notifications controls. This includes options to make the conversation stay Silent to prevent it from ringing your chat, and if you tap Lock Screen, a pop-up menu will give you the option to prevent notifications. Tap Don’t show notifications at all to enable.

Hide and block MMS chats on an Android phone

On an Android phone with Google Messages, follow the same steps to access options for controlling notifications. This includes visiting the MMS chat thread and then tapping either the name of the conversation or the names of the participants at the top to bring up the Group Details menu. You won’t see a Leave Group option like you did with an RCS thread, but you do get the same ability to tap Notifications to access controls for hiding the conversation. This includes the same options for turning the conversation to Silent and to select Don’t show notifications at all.

SMS vs. MMS vs. RCS

SMS stands for Short Message Service and debuted in 1992. Text messages are limited to 160 characters. MMS stands for Multimedia Messaging Service and supports sending photos, videos or other files and messages longer than 160 characters. MMS supports a group of people chatting in a single conversation thread, while SMS can text multiple people at once but is sent as individual messages to each person. RCS, which launched 15 years ago, is short for Rich Communication Services and can show typing indicators, read receipts and has end-to-end encryption.

While cross-platform chat apps like WhatsApp, Signal and Telegram have better controls for conversations, encryption and privacy, regardless of the type of phone participants are using, they don’t support SMS, MMS or RCS. That’s why the default messaging app on most phones is still widely used, even if it means that a group chat is on a less feature-filled, unsecured standard like MMS.
