Galaxy Book 3 First Look: Samsung’s Pro Laptops Are Leveling Up

With a 16-inch AMOLED display, lots of ports and seamless connectivity with other Galaxy devices, the Ultra redefines premium laptops for Samsung.

Samsung’s Galaxy Book Pro laptops are leveling up. At Samsung’s Unpacked event Wednesday, the electronics giant announced the Galaxy Book 3 Ultra laptop alongside its latest flagship Galaxy S23 phones.

Like Samsung’s top Galaxy Ultra phones and Galaxy Tab S8 Ultra tablet, the Ultra laptop will have the best performance, a ton of features and a killer display. But like the other Ultra devices, the Ultra laptop might be more computer than you need. Samsung also has the Galaxy Book 3 Pro and Pro 360, which are a notch below the Ultra in performance, but have a lot of features in common, along with their own added extras.

The Galaxy Book 3 Ultra is the star, though, and thankfully it fixes two things I didn’t like about the otherwise excellent Galaxy Book 2 Pro models. One issue was their displays. While they had great-looking AMOLED panels, they were 16:9, 1080p widescreens; most premium laptops use higher-resolution 16:10 panels that give you more vertical space. The 16-inch Galaxy Book 3 Ultra makes the jump to 16:10. It’s still an AMOLED panel, too, so you’re going to get amazing color and contrast. Plus it has a 120Hz refresh rate for smoother-looking video; its resolution is 2,880×1,800 pixels.

The second issue I had with the Book 2 Pro was that Samsung didn’t offer any options for discrete graphics and frankly, if you’re going to call something «Pro» you should offer something stronger than integrated graphics. That doesn’t change with the Book 3 Pro models, but the Ultra will have either an Nvidia GeForce RTX 4050 or 4070 graphics chip and they’ll be paired with a 13th-gen Intel Core i7 or i9 processor, respectively, giving the Ultra some pro-level laptop performance.

Those components drive the price up considerably, with the Core i7 and RTX 4050 configuration starting at $2,400 and the Core i9 and RTX 4070 pairing going for $3,000. (Pricing and availability weren’t announced for the UK or Australia, but the entry price converts to 1,950 and AU$3,400.) You get a lot of other great features for those prices like a 1080p webcam, a quad-speaker audio system, a fingerprint reader on the power button and a larger 76-watt-hour battery. The Ultra also has more ports than the Galaxy Book 2 Pro, with a USB-A port and HDMI 2.0 output joining its two Thunderbolt USB-C ports, microSD card slot and headphone jack.

The good news is almost all of these things trickle down to the Pro models, with the big exceptions being the Core i9 processor and the discrete graphics. The nice thing about that is the 16-inch Galaxy Book 3 Pro laptop is 4 millimeters thinner and it’s about a half pound lighter than the 16.5-mm thick, 4-pound (1.8-kilogram) Ultra. The Galaxy Book 3 Pro will also be available in a 14-inch size that’s just 2.6 pounds (1.2 kilograms).

There’s also a 16-inch Galaxy Book 3 Pro 360 two-in-one, which is large for a two-in-one, but since it comes with one of Samsung’s excellent S Pens, you’ll have a lot of room to draw or take notes, plus it’ll make a nice digital whiteboard for meetings. And again, all of the features like the high-res webcam, port assortment and quad speakers on the Ultra are here, too. It’s also the only model to come with optional 5G wireless.

Also, just like earlier Galaxy Books, the new Ultra and Pro laptops are made to work with other Galaxy devices. Things like sending files back and forth between your phone and laptop are easy. You can, for instance, start working on a file on your Galaxy phone and finish up on the Galaxy Book. Or you can use a Galaxy Tab S8 as a wireless external display to extend the laptop’s screen. Your Galaxy Buds can automatically switch between devices as well. This extra layer of interoperability is something Apple does well with its iPhones, iPads and MacBooks, and Samsung is quickly catching up with help from Intel and Microsoft. These laptops have enterprise-level security, too, since they meet Microsoft’s secured-core PC requirements.

There is one thing that Samsung kept the same as the previous generations and that’s the overall look. They’re nice and clean, if a bit unexciting, especially compared to Samsung’s phones, which come in several colors — these come in graphite or beige. Build quality is improved, though. They’re sturdier, stiffer and stronger, which is certainly a plus even if they’re a bit heavier because of it.

The Samsung Galaxy Book 3 Ultra and Pro and Pro 360 laptops are available to preorder now through Samsung’s site and the Pro models are expected to start shipping on Feb. 17.

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications

Don’t expect the storm to cause a lingering problem, though.

A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.

The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.

Even so, NOAA said, «the general public should not be concerned.»

A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.

In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.

Switching poles

Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.

During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.

Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.

But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.

If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It

It’s your last chance until 2044.

Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.

A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.

The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.

Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.

Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.

Total solar eclipse path

The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.

By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.

Best places to watch the Great American Eclipse

When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.

Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.

So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.

Eclipse eye safety and photography

As with any solar eclipse, it’s critical you keep eye safety in mind.

During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.

If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.

If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.

There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.

2024 eclipse compared to 2017

The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.

The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.
