Sony Xperia Z2 Specs

Sony Xperia Z2, successor of the Xperia Z1, gets new updates such new hardware upgrades, better screen display and resolution, brand-new operating system and upcoming speculated release date in April 2014. Know the five exciting characteristics of the upcoming Xperia Z2 Avatar.

Brand New Operating System

Sony Mobile released Xperia Z1 with Android 4.2.2 Jelly Bean which is a little disappointing compared to the Samsung’s Galaxy Note 3 running Android 4.3. But the Japanese tech company may change views using Android 4.4 KitKat on the rumoured upcoming successor – the Xperia Z2 Avatar.

Google will release Android 4.4 KitKat around October or November 2013 which allows manufacturers to grab the source code before 2014 begins. According to CNET, the early build of Android 4.4 KitKat could be an incremental update with tweaks included.

-          Integrated options for printing: Sony may enable their own printing app

-          Wireless payments: More ability for international owners to purchase add-ons

-          Smoother animations: Expect changes in the Xperia UI

-          Palette colour scheme

-          Enhancements on the camera and gallery apps: Sony will change these with their own

-          Import and export images in PDF format with variety of sizes and quality

-          Application of new native filters and effects

-          Native apps such as Google Drive, Keep and QuickOffice

Android 4.4 KitKat is also speculated to be lightweight on the memory which will greatly improve system performance of the Xperia Z2.

IGZO Screen Display

Sony may use Sharp’s IGZO display technology on the Xperia Z2 which also rumoured to be featured on several upcoming devices from other brands. IGZO offers a very pixel-dense display that is easy on the battery compared to TFT LCD screens. In addition, pixel density of 500ppi is also possible on IGZO screens.

Xperia Z2 is rumoured to 505ppi pixel density, higher than the Xperia Z1’s 441ppi and HTC One’s 469ppi for crispier and more detailed images and videos.

Display Engines for Mobile

Triluminos with X-Reality for mobile are also expected to be included on Xperia Z2 to improve contrast, brightness, tones and colours. Moreover, it can boost colour gamut of up to 50 per cent larger than conventional LCD panels, better reproduction of tones and textures, sharper images and refines tune saturation.

Sony G Lens

Sony Xperia Z2 will have the same 20.7MP camera of the Xperia Z1 which is a Sony G lens. Sony G lens feature Carl Zeiss optics and improves in-focus image quality, defocuses background areas, gathers light better and minimised flare for higher contrast. In addition, Xperia Z2 will sport a 3.5MP front-facing camera and possibly features an Exmor RS imaging processor.

Xenon Flash

LED flash is common among smartphones and tablets since it can be minimised with relatively low power consumption in contrast with Xenon flash. However, Sony may replace LED flash for Xperia Z2 with Xenon due to following benefits.

1.      Bursts brighter than LED

2.      Flashes with longer range

3.      Reduces blur on images during night shots

4.      Significantly produces less noise in images

The downside on the upcoming smartphone would be the battery consumption and possible larger space occupied by the Xenon flash. It is unknown yet if Sony will take the bulk on the device.

Exclusive Camera Apps

Sony Xperia Z1 exclusive camera applications such as Info-Eye, Timeshift-Burst and AR Effect which can be useful in many scenarios. Info-Eye allows the user to get useful information about the object, Timeshift-Burst captures 61 frames within 2 seconds which gives a selection of photos to choose from and AR Effect adds fun animations on your image capture.

Xperia Z2 may get improvements on the three apps such as faster or offline saving of Info-Eye information, more frames on Timeshift-Burst and AR Effects available for video recording.

Waterproof and Dust Resistance

It is definite that Xperia Z2 will have the same proofing on the Xperia Z1 such as IP55 and IP58 ratings. IP55/IP58 features waterproof and dust-resistant protection on the device and allows you to use it underwater. Hopefully, Sony could use a better screen protection other than tempered glass for Xperia Z2.

Slim Unibody

An alleged picture of Sony Xperia Z2 leaked and was revealed by Android SaS. It is very similar to the Sony Xperia Z except for the bigger display and super slim design. Since Sony Mobile apparently set rules to employees not to upload images or use third-party benchmarking applications, there is no way yet to determine if the image is accurate.

Processor and RAM

Sony will still use Qualcomm’s Snapdragon quad-core processor to power up the Xperia Z2 and a 3GB RAM to handle multi-tasking and improve app loading of the device. Android 4.4 KitKat’s speculated better multi-core processor support and lightweight system may greatly help Xperia Z2 in many aspects of performance such as 3D games rendering, camera processing, network stability and many more.

Release Date

As of now, rumours are setting their expectations in April 2014 as Sony’s possible release date for Xperia Z2. It is also predicted that the upcoming smartphone will be priced a little bit expensive compared to the launching price of Xperia Z1. In addition, Sony may produce 3G and 4G LTE capable models of Xperia Z2 Avatar.

ESO’s VLT provides new clues to help solve Solar lithium mystery

An international team led by astronomers in Brazil has used ESO’s Very Large Telescope to identify and study the oldest solar twin known to date. Located 250 light-years from Earth, the star HIP 102152 is more like the Sun than any other solar twin — except that it is nearly four billion years older.

This image tracks the life of a Sun-like star, from its birth on the left side of the frame to its evolution into a red giant star on the right. On the left the star is seen as a protostar, embedded within a dusty disc of material as it forms. It later becomes a star like our Sun. After spending the majority of its life in this stage, the star's core begins to gradually heat up, the star expands and becomes redder until it transforms into a red giant. Following this stage, the star will push its outer layers into the surrounding space to form an object known as a planetary nebula, while the core of the star itself will cool into a small, dense remnant called a white dwarf star. Marked on the lower timeline are where our Sun and solar twins 18 Sco and HIP 102152 are in this life cycle. The Sun is 4.6 billion years old and 18 Sco is 2.9 billion years old, while the oldest solar twin is some 8.2 billion years old —  the oldest solar twin ever identified. By studying HIP 102152, we can get a glimpse of what the future holds for our Sun. This image is illustrative; the ages, sizes, and colours are approximate (not to scale). The protostar stage, on the far left of this image, can be some 2000  times larger than our Sun. The red giant stage, on the far right of this  image, can be some 100 times larger than the Sun.

This older, but almost identical, twin gives us an unprecedented chance to see how the Sun will look when it ages. The new observations also provide an important first clear link between a star’s age and its lithium content, and in addition suggest that HIP 102152 may be host to rocky terrestrial planets.
Astronomers have only been observing the Sun with telescopes for 400 years — a tiny fraction of the Sun’s age of 4.6 billion years. It is very hard to study the history and future evolution of our star, but we can do this by hunting for rare stars that are almost exactly like our own, but at different stages of their lives. Now astronomers have identified a star that is essentially an identical twin to our Sun, but 4 billion years older — almost like seeing a real version of the twin paradox in action [1].
Jorge Melendez (Universidade de São Paulo, Brazil), the leader of the team and co-author of the new paper explains: “For decades, astronomers have been searching for solar twins in order to know our own life-giving Sun better. But very few have been found since the first one was discovered in 1997. We have now obtained superb-quality spectra from the VLT and can scrutinise solar twins with extreme precision, to answer the question of whether the Sun is special.”

This image shows solar twin HIP 102152, a star located 250 light-years from Earth in the constellation of Capricornus (The Sea Goat). HIP 102152 is more like the Sun than any other solar twin — apart from the fact that it is nearly four billion years older, giving us an unprecedented chance to study how the Sun will look when it ages. It is the oldest solar twin identified to date, and was studied by an international team using ESO’s Very Large Telescope, led by astronomers in Brazil. The different colours of the star are caused by the star moving slightly between the two exposures, many years apart.

The team studied two solar twins [2] — one that was thought to be younger than the Sun (18 Scorpii) and one that was expected to be older (HIP 102152). They used the UVES spectrograph on the Very Large Telescope (VLT) at ESO’s Paranal Observatory to split up the light into its component colours so that the chemical composition and other properties of these stars could be studied in great detail.
They found that HIP 102152 in the constellation of Capricornus (The Sea Goat) is the oldest solar twin known to date. It is estimated to be 8.2 billion years old, compared to 4.6 billion years for our own Sun. On the other hand 18 Scorpii was confirmed to be younger than the Sun — about 2.9 billion years old.
Studying the ancient solar twin HIP 102152 allows scientists to predict what may happen to our own Sun when it reaches that age, and they have already made one significant discovery. “One issue we wanted to address is whether or not the Sun is typical in composition,” says Melendez. “Most importantly, why does it have such a strangely low lithium content?
Lithium, the third element in the periodic table, was created in the Big Bang along with hydrogen and helium. Astronomers have pondered for years over why some stars appear to have less lithium than others. With the new observations of HIP 102152, astronomers have taken a big step towards solving this mystery by pinning down a strong correlation between a Sun-like star’s age and its lithium content.
Our own Sun now has just 1% of the lithium content that was present in the material from which it formed. Examinations of younger solar twins have hinted that these younger siblings contain significantly larger amounts of lithium, but up to now scientists could not prove a clear correlation between age and lithium content [3].
TalaWanda Monroe (Universidade de São Paulo), the lead author on the new paper, concludes: “We have found that HIP 102152 has very low levels of lithium. This demonstrates clearly for the first time that older solar twins do indeed have less lithium than our own Sun or younger solar twins. We can now be certain that stars somehow destroy their lithium as they age, and that the Sun’s lithium content appears to be normal for its age.” [4]
A final twist in the story is that HIP 102152 has an unusual chemical composition pattern that is subtly different to most other solar twins, but similar to the Sun. They both show a deficiency of the elements that are abundant in meteorites and on Earth. This is a strong hint that HIP 102152 may host terrestrial rocky planets [5].

NOTES

[1] Many people have heard of the twin paradox: one identical twin takes a space journey and comes back to Earth younger than their sibling. Although there is no time travelling involved here, we see two distinctly different ages for these two very similar stars — snapshots of the Sun’s life at different stages.
[2] Solar twins, solar analogues and solar-type stars are categories of stars according to their similarity to our own Sun. Solar twins are the most similar to our Sun, as they have very similar masses, temperatures, and chemical abundances. Solar twins are rare but the other classes, where the similarity is less precise, are much more common.
[3] Previous studies have indicated that a star’s lithium content could also be affected if it hosts giant planets (eso0942eso0118,Nature paper), although these results have been debated (ann1046).
[4] It is still unclear exactly how lithium is destroyed within the stars, although several processes have been proposed to transport lithium from the surface of a star into its deeper layers, where it is then destroyed.
[5] If a star contains less of the elements that we commonly find in rocky bodies, this indicates that it is likely to host rocky terrestrial planets because such planets lock up these elements as they form from a large disc surrounding the star. The suggestion that HIP 102152 may host such planets is further reinforced by the radial velocity monitoring of this star with ESO’s HARPS spectrograph, which indicates that inside the star’s habitable zone there are no giant planets. This would allow the existence of potential Earth-like planets around HIP 102152; in systems with giant planets existing close in to their star, the chances of finding terrestrial planets are much less as these small rocky bodies are disturbed and disrupted.
