Watch Plasma Rain Fall on the Sun After Telescope Upgrade

Understanding the Sun Through Advanced Technology

Looking directly at the sun is a dangerous practice, something that most people learn early in life. Even during an eclipse, when the sun is partially obscured, special protective glasses are essential to prevent eye damage. However, for some professionals, their work involves studying the sun up close—using advanced equipment to gather critical data.

The Big Bear Solar Observatory (BBSO) is one such facility where scientists use powerful telescopes to observe our star. One of its key instruments is the Goode Solar Telescope (GST), which has provided valuable insights into solar activity. Despite its capabilities, the telescope’s location on Earth meant it faced challenges in capturing the clearest images of the sun's corona due to atmospheric distortion. This limitation restricted the resolution to about 1,000 kilometers, which, while impressive, wasn’t sufficient for more detailed studies.

For over eight decades, improving this resolution proved to be a significant challenge with minimal progress. However, a recent upgrade has changed the game entirely. The installation of a new system now allows the GST to capture details as small as 63 kilometers. This advancement is made possible through a technology known as adaptive optics, which helps counteract the effects of atmospheric interference.

Adaptive Optics: A Game-Changer in Solar Observation

Nicolas Gorceix, an Optical Engineer and Chief Observer at BBSO, explained the impact of this upgrade. He noted that atmospheric turbulence significantly degrades the quality of images captured by telescopes. Adaptive optics functions similarly to autofocus and image stabilization in smartphones but instead corrects for distortions caused by the atmosphere rather than user movement.

This technology has been in use for over two decades in night-time astronomy, but applying it to solar observations was a long-standing challenge. Thomas Rimmele, NSO Chief Technologist and the developer of the first adaptive optics system for solar observation, emphasized the significance of the new coronal adaptive optics system. He stated that it closes a decades-old gap, delivering images of the sun’s corona at a resolution of 63 kilometers—the theoretical limit of the 1.6-meter Goode Solar Telescope.

Capturing the Sun Like Never Before

With the upgraded system now in operation, researchers have been able to capture unprecedented images and videos of the sun. One of the most remarkable outputs so far is a video showing plasma “raindrops” being ejected from the sun’s surface and falling back down. The footage also reveals the sun’s surface edge in extraordinary detail, showcasing jagged textures that were previously unseen.

This level of clarity provides a deeper understanding of solar dynamics and could lead to new discoveries about the sun’s behavior. The visual representation of the sun’s surface is unlike anything seen before, offering a glimpse into the complex processes occurring on our nearest star.

The Future of Solar Research

The advancements made at BBSO highlight the importance of continuous technological innovation in scientific research. As telescopes become more sophisticated, they open up new possibilities for understanding celestial phenomena. The integration of adaptive optics into solar observation marks a significant milestone, enabling scientists to study the sun with greater precision than ever before.

This breakthrough not only enhances our knowledge of the sun but also sets a precedent for future developments in observational astronomy. With each improvement, we move closer to unraveling the mysteries of our universe.

Apple iPhone 17 Unveiled: August 2025 Preview Guide

Overview of the iPhone 17

The iPhone 17 is still months away, but speculation and rumors about its features are already growing. In 2025, Apple is expected to make some significant changes to its product lineup, potentially introducing an “Air” model that is said to be extremely slim. While the base model will remain as the iPhone 17, along with the iPhone 17 Pro and iPhone 17 Pro Max, there are whispers that the “Plus” model may be discontinued in favor of the iPhone 17 Air.

This article provides a preview of the upcoming iPhone 17, compiling all the latest rumors and leaks about the device. It will be updated frequently as more information becomes available ahead of the September release.

iPhone 17 Specifications

Surprisingly, there haven’t been many leaks regarding the specifications of the iPhone 17. Most of the focus has been on the Air and Pro models. One ongoing rumor is that the iPhone 17 might feature a 120Hz display. However, it's unlikely that Apple will include this feature since they market the 120Hz refresh rate under the term "ProMotion," which is exclusive to their Pro devices. Instead, a 90Hz screen could be a more realistic possibility, though it would still lag behind some budget smartphones like the Pixel 9a, which offers a 120Hz display.

New A19 Chipset

The iPhone 17 is expected to come equipped with the A19 chip. This chipset will not use TSMC’s next-generation 2nm process but will instead utilize an upgraded 3nm process. The A19 is likely to be manufactured using TSMC’s N3P process, which began mass production in late 2024. Similar to the iPhone 16 series, the base model will receive the A19, while the Pro models will get the A19 Pro. The primary difference between these chips will be the number of CPU and GPU cores.

In terms of RAM, the iPhone 17 is expected to retain 8GB of RAM, following the upgrade from 6GB in the iPhone 15 to 8GB in the iPhone 16. Meanwhile, the Pro models are anticipated to jump to 12GB of RAM.

Despite launching its own modem for the iPhone 16e, Apple is not expected to use its in-house modem for the iPhone 17. It may only be available for the iPhone 17 Air. The reason for this is volume; the Air is likely to be a low-volume model, so Apple won't need to produce as many modems. Additionally, the in-house modem does not support mmWave 5G, which could affect carrier support, such as Verizon.

ProMotion Display

The regular iPhone 17 is rumored to feature a ProMotion display with a variable refresh rate up to 120Hz. However, a 90Hz refresh rate is more probable. Apple refers to higher refresh rates as "ProMotion," which is currently exclusive to their Pro devices. This feature is not available on non-Pro iPhones, iPads, or MacBooks.

iPhone 17 Pricing

Some rumors suggest that the iPhone 17 will maintain the same price as the base model has been for several years, likely at $799. This would create a $200 gap between the iPhone 17 and the iPhone 16e. If the iPhone 17 Air starts at $899, it would be unusual for the base model to cost more than $799.

The Pro models are also expected to keep the same pricing, with the iPhone 17 Pro at $999 and the iPhone 17 Pro Max at $1,199.

However, some analysts predict a potential $50 price increase for the entire iPhone 17 lineup. While this rumor has circulated since the iPhone X in 2018, no actual price increases have occurred in the US. Nonetheless, it may be time for a price hike after seven years.

iPhone 17 Design

Several renders of the iPhone 17 have surfaced, showing Apple moving towards a camera setup similar to a camera bar, akin to the Google Pixel. The iPhone 17 Air is expected to have a camera bar that spans the top of the phone, while the iPhone 17 itself will be similar but slightly thinner, featuring two cameras instead of one.

These cameras will still be positioned side by side, with Face ID remaining off-center. The placement of the cameras is due to the size of the Face ID components, making it impractical to place a camera behind them. Otherwise, the iPhone 17 is expected to retain its current design, including the Camera Control and Action Buttons. Slightly smaller bezels and a smaller dynamic island are also anticipated.

iPhone 17 Cameras

The iPhone 17 is expected to feature a 24-megapixel front-facing camera across the entire lineup, with a six-element lens. This would be a significant upgrade from the current 12-megapixel camera on the iPhone. However, this is likely the only camera improvement for the base model.

The Pro models, on the other hand, are expected to have a 48MP primary camera, a 48MP ultra-wide camera, and a 48MP tetraprism telephoto camera. At least one model will include a mechanical aperture, allowing users to adjust the size of the aperture. This feature is expected to be on the Pro Max model.

iPhone 17 Connectivity

Apple is expected to remove the SIM card tray from even more countries, transitioning to eSIM-only support. This change was first introduced in the US with the iPhone 14. WiFi 7 will be available on the iPhone 17, supporting 2.4GHz, 5GHz, and 6GHz for faster speeds and lower latency. Bluetooth 5.3 support is also anticipated.

As mentioned earlier, Apple’s in-house modem is not expected to be included in the base model, only in the Air. Apple will continue using Qualcomm’s modems for the other iPhone 17 models.

iPhone 17 Launch Date

Apple typically announces new iPhones in September, usually a week after Labor Day. The iPhone 17, 17 Pro, and 17 Pro Max are expected to ship in late September. The iPhone 17 Air may ship slightly later, possibly in October.

On August 5, a German carrier reported that the iPhone 17 launch event will take place on September 9, aligning with Apple’s previous launch timelines.
