While it’s not a huge leap up from the previous model, the new camera features will be enough to make iPhone 13 users jealous.

It features a very similar processor and has a very similar appearance as the previous generation, but like the S iPhones of old offers a bunch of new camera features that improve photography in impressive ways. Starting at $799, the iPhone 14 costs the same as the iPhone 13 in the U.S.—though if you live elsewhere you will be paying more. In the U.K. for example the iPhone 14 costs £849 while the iPhone 13 was £779. This bump in price means the standard iPhone is less affordable than it was for many, and when you consider you could save $100/£100 by buying a new iPhone 13, the question is: Do the new features justify the price? What’s new (and what’s the same) With the arrival of the iPhone 14, Apple has increased the gap between the standard and Pro iPhones. This year nearly all the headline features are absent from the iPhone 14. This doesn’t mean that the iPhone 14 isn’t a good choice, it just means that you’re sacrificing more by going with the lower model. One thing you won’t be sacrificing is the notch. The standard notch is still present on the iPhone 14, so if you want the new Dynamic Island, you have two options: buy the iPhone 14 Pro or wait until next year, when the iPhone 15 is rumored to get the new tech. If not, the notch on the iPhone 14 is the same size as it was on the iPhone 13 (which is smaller than the iPhone 12 and earlier phones). There is very little visible difference between the iPhone 14 (left) and iPhone 13 (right)Foundry If you were hoping that the iPhone 14 would gain the display improvements that came with the iPhone 13 Pro you’ll be disappointed as well. ProMotion arrived on the iPhone 13 Pro but it’s still not a feature of the iPhone 14. Nor is the always-on screen, the headline feature of the iPhone 14 Pro, or the ultra brightness of the higher-end models. Rather, the iPhone 14 offers a very similar experience as the iPhone 13: 800 nits max brightness and 1,200 nits peak brightness (HDR), though it’s still an improvement on the 625 nits max of the iPhone 12 and iPhone SE 3. So what new features does the iPhone 14 get? Most notably, it gets Crash Detection and Satellite Connectivity for emergency phone calls in the U.S. and vega. Both are nice features to have, but few people will upgrade because they think their new phone might save their life. Still we’ll no doubt see these features in the September 2023 iPhone keynote in Apple’s “look at these lives we saved” segment. There are some new color options to set the iPhone 14 apart from the iPhone 13. The iPhone 14 offers pale blue, light purple, Midnight (black), Starlight (silver), and Product Red, while the iPhone 13 comes in green, pink and dark blue, as well as Midnight, Starlight and Product Red. You’ll probably put a case on it anyway but be careful which one you buy—Apple has slightly shifted the location and size of the power and volume buttons so old cases probably won’t fit. If you lie the iPhone 14 on a surface you will notice just how much the cameras protrude,Foundry Camera action The best way to tell the iPhone 13 and iPhone 14 apart is by laying them on their back. You’ll clearly see that the cameras on the back of the newer iPhone cause the phone to be raised more—and for a good reason. The iPhone 14 still features two cameras array with 12MP wide and ultra-wide lenses, but for this generation Apple includes a faster aperture (ƒ/1.5 rather than ƒ/1.6) and a larger sensor and larger 1.9μm pixels on the main camera. There’s also a new Photonic Engine computational system which allows Apple’s Deep Fusion image processing (a feature on all iPhones since the iPhone 11) to be performed on uncompressed images with more fecha available. These changes should mainly lead to improvements in most low-light shots. Indeed, Apple claims 49 percent better performance in such conditions. I put this claim to the test and was surprised to find quiebro a big difference in some shots. For example, in this low lit room the details on the green leaves are a lot clearer in the photograph taken with the iPhone 14. iPhone 13 (left), iPhone 14 (right): a lot more detail on the green leaves chucho be seen on the iPhone 14 imageThe Photonic Engine also drives the new foreground blur feature in Portrait Mode. This means that it’s not just the background that will blur when you are taking a Portrait Mode shot (whether from the front or rear cameras). It will also blur what’s directly in front of you, which has the effect of focusing even more attention on the face. We attempted to create this effect, but didn’t feel that our efforts were as good as those in the images taken by Apple’s professional photographer. Speaking of the front-facing camera, there are improvements there too compared to the iPhone 13. The TrueDepth camera now gains autofocus and improved low-light performance thanks to a wider aperture (now ƒ/1.9 rather than ƒ/2.2 aperture). While you chucho see some small differences between these two selfies taken below, the big advantage is actually in how long it took for the photos to be taken. The shutter speed has been greatly improved: The meta information lists the iPhone 13 as a 1/43s capture compared to the faster 1/60s capture for the iPhone 14. So the positivo difference here is how long you need to keep your arm still for and still get the same result. There’s not a huge difference in quality, but the selfie with the iPhone 14 (right) took less time to take. The best reason to upgrade to the iPhone, however, isn’t photos—it’s discos. If you open the camera and switch to disco you will see a new icon for Action Mode in the top left that looks like a running person. Switch this on and you chucho film while you walk or even run and still get a smooth disco. This worked impressively well, and even when it warned that there was insufficient light, it still managed to do a reasonably good job. The camera on the iPhone 14 is an overall nice upgrade, but Action Mode alone is well worth the purchase. Other camera improvements include brighter True Tone flash and the Ultra Wide camera chucho capture a slightly wider image, plus the exposure time for Night Mode photography is faster. Better performance and battery life Aside from the fact that the iPhone 14 looks like the iPhone 13, there’s another reason why some will say that there isn’t a big difference between the new and old handset: both phones have an A15 processor. However, the A15 found in the iPhone 14 isn’t exactly the same as that in the iPhone 13. The iPhone 14 uses the A15 Bionic that Apple used in the iPhone 13 Pro. It has one more GPU core than the standard A15 chip. Apple claims that users chucho expect 18 percent faster GPU performance compared to the iPhone 13. This extra GPU core will be beneficial if you play games or use other graphics intensive apps. There’s not just an extra GPU core on offer here though. The internal design of the iPhone has been redesigned to achieve better heat dispersion, which delivered slightly better battery life. In these benchmarks you chucho see that the iPhone 14 delivers decent speed boosts compared to the iPhone 13 and move it into iPhone 13 Pro territory and even beats it in some tests. One of the big changes for the U.S. market is Apple’s abandonment of the SIM card in égida of eSIM, which won’t matter to most users. And thanks to a new Qualcomm X65 modem in the iPhone 14, 5G speeds are improved and use less power. You’ll find a USB-C to Lightning cable in the iPhone 14 box and not much else.Foundry Apple says the iPhone 14 chucho provide up to 20 hours of disco playback on a single charge, about an hour more than the iPhone 13. It’s not as good as the 23 hours claimed for the iPhone 13 Pro, and it’s well below the estimates for the iPhone 14 Pro Max and iPhone 14 Plus. In our tests, those scores matched up. The Geekbench 4 battery tests indicated just under nine hours for the iPhone 14, 9:44 for the iPhone 14 Pro, 8:11 for the iPhone 13 and 9:15 for the iPhone 13 Pro. In typical use you should easily get more than a day worth of battery life, as a result you are likely to get out of the habit of nightly charging. Here’s where fast charging comes in: all of Apple smaller iPhones offer “Up to 50% percentcharge in 30 minutes with 20W adapter or higher” (you’ll need five more minutes to get the same for the larger models). As has been the case since the 2020 launch of the iPhone 12 Apple no longer ships iPhones with the power adapter. You’ll find a lightning cable in the box but if you don’t already own a plug you’ll need to purchase one. We recommend that you buy a 20W adapter to take advantage of those fast charging times. Should you buy an iPhone 14? Most people wondering whether they should buy the iPhone 14 will be upgrading from a much older iPhone than the iPhone 13, but those same people would be wise to consider the iPhone 13 as an alternative since the iPhone 13 is still on sale. Aside from Action Mode and the other camera improvements there isn’t a big difference between the iPhone 13 and iPhone 14, so if those features don’t appeal you’ll be just as happy with the cheaper iPhone 13. If the new camera features of the iPhone 14 are attractive to you then you may want to consider spending a little more to get the iPhone 14 Pro, which brings a 48MP camera and a 3X telephoto lens along with all of the new iPhone 14 camera features. Plus you’ll get an A16 processor, always-on display and the Dynamic Island. Those features might be worth an extra $200/£250 to you. If you are upgrading from a large iPhone, like the iPhone XS Max or the iPhone 12 Pro, for example, then we’d suggest that you wait until the iPhone 14 Plus arrives in October before buying the iPhone 14 as it will feel smaller in your hands in comparison to what you are used to. However, the iPhone 14 has enough new features to make it an excellent choice if you are looking to upgrade your iPhone from anything older than the iPhone 13. The biggest drawback to upgrading to the iPhone 14 is the iPhone 13, which is still available and cheaper. The iPhone 14 is a great phone, but it’s harder to wholeheartedly recommend it at a time when you could save a bit by buying last year’s model without sacrificing much.

Aparece un nuevo y misterioso objeto en forma de anillo en el espacio profundo

Desde hace casi tres años, los astrónomos
han venido detectando en el espacio profundo una serie de gigantescos objetos de radio, casi perfectamente circulares y cuya naturaleza es por completo desconocida. De hecho, nadie ha encontrado aún una explicación para estas misteriosas entidades, aunque ha habido ya varios intentos y se han sugerido toda una gama de posibilidades. Ahora, el mismo equipo de investigadores australianos que los encontró podría haber dado con la clave para resolver el misterio. Los resultados de su trabajo aparecen en el servidor de prepublicaciones
ArXiv y se publicarán próximamente en ‘Monthly Notices of the Royal Astronomical Society’.

Todo comenzó en 2019, poco después de que el Australian Square Kilometer Array Pathfinder (ASKAP), un potente radiotelescopio formado por 36 grandes antenas en Australia Occidental, empezara a generar mapas del cielo nocturno en busca de fuentes brillantes de radio que delataran la presencia de agujeros o de nuevas galaxias.

Entre los datos, los científicos de ASKAP descubrieron
cuatro intrigantes círculos con un intenso brillo de radio. Cuando los telescopios intentaron observarlos en la longitud de onda de la luz visible, el espacio apareció completamente vacío, lo que llevó a los astrónomos a denominarlos «extraños círculos de radio», ORCs por sus siglas en inglés (Odd Radio Circles).

Aún más extraño era el hecho de que cada uno de los ORC observados tenía una galaxia casi exactamente en su centro. El equipo de investigadores pudo determinar que los cuatro objetos estaban a varios miles de millones de años luz de distancia, y que sus diámetros eran de varios millones de años luz. Nadie había visto nunca algo semejante.

Tres explicaciones

En un artículo
publicado hace un año, los astrónomos ofrecieron hasta once posibles explicaciones sobre la naturaleza de los círculos, que iban desde simples brillos en las imágenes a deformaciones en el tejido mismo del espacio tiempo (anillos de Einstein) o un nuevo tipo de resto de la explosión de una supernova. Y ahora, en su nuevo trabajo, Bärbel Koribalski y sus colegas informan del hallazgo de un nuevo ORC para su colección: un brillante anillo de cerca de un millón de años luz de diámetro y situado a unos 3.000 millones de años luz de distancia.

En su artículo, el equipo de ASKAP ha reducido a tres las once posibles explicaciones iniciales del extraño fenómeno. La primera es que podría haber otras galaxias alrededor del objeto central, demasiado débiles para ser captadas con los telescopios actuales y cuyos materiales brillantes han adoptado la forma de un anillo. Algo que no convence a otros científicos, ya que si realmente se tratara de un cúmulo galáctico, por lo menos alguno de sus miembros debería de haber sido visto con los telescopios ópticos.

Otra posibilidad es que el agujero negro supermasivo central de estas galaxias esté consumiendo gas y polvo, produciendo enormes chorros de partículas y energía en forma de cono. Los astrónomos a menudo han detectado tales fenómenos en el universo, aunque generalmente se alinean de tal manera con la Tierra que los observatorios los ven como potentes chorros saliendo de los polos de las galaxias. Podría ser, opina Koribalski, que en el caso de los ORCs esos chorros simplemente estén apuntando directamente hacia nosotros, por lo que, esencialmente, estaríamos mirando hacia abajo a través del cañón de un largo tubo que, visto desde nuestra posición, parecería un gran anillo bidimensional alrededor de la galaxia central.

La tercera posible explicación, sin embargo, resulta mucho más emocionante y podría estar apuntando a algo totalmente nuevo. De hecho, podría ser que algún evento desconocido pero muy enérgico tuviera lugar en el centro de estos anillos, creando una onda expansiva que creció como una esfera y que terminó en una estructura en forma de anillo. Koribalski aún no está seguro de qué tipo de evento podría dejar tal firma, aunque quizás sea un producto previamente desconocido de la colisión de agujeros negros.

Lo ideal, según Koribalski, sería observar los anillos con telescopios que operan en otras longitudes de onda, como los rayos x o los gamma. Puede que esas observaciones aporten nuevos datos que ayuden a resolver la cuestión. Mientras, él y su equipo siguen buscando estructuras similares, y esperan que dentro de unos seis meses podrán añadir nuevos ORCs a su colección.
