The $669 OnePlus 7 Pro makes the $1,000 iPhones and Galaxies look overpriced

In case you couldn’t tell by the specs, OnePlus has given its new phone a surname to drive home just how much different it is. From the design and display to the camera, the OnePlus 7 Pro brings a whole lot more than the usual processor refresh to keep pace with the highest-end Android flagships.

To emphasize the point even further, OnePlus isn’t releasing a non-pro version of the 7. As such, OnePlus will continue to sell two variants of the 6T “for users looking for a premium flagship experience” at a $30 cut, bringing the 128GB model down to $549 and the 256GB version to $599. 

The OnePlus 7 Pro with 6GB of RAM and 128GB of storage starts at $669. Yes, that’s $120 more than the entry-level OnePlus 6T (after today’s $30 price cut) and within shouting distance of the $740 iPhone XR and Galaxy S10e. But it’s difficult to find much fault with this much phone at less than $700.

Where the OnePlus 6T has a small notch in the center of the screen, the 7 Pro has none. Nor does it have a hole. Or much of a bezel. So where does OnePlus hide its 16MP front camera? Inside a mechanism that slides out of the top edge when needed. We’ve seen similar implementations from the likes of Vivo and Oppo, but the OnePlus 7 Pro is the first U.S. phone to feature a pop-up camera, and it’s certainly a fun, unique feature—the kind of cool tech you’d expect from Apple or Samsung.

When you want to take a selfie, the OnePlus 7 Pro’s camera will rise out of the top edge.

But the front camera isn’t what makes the OnePlus 7 a “pro” phone. Far from it. The specs in this phone are about as good as you’re going to find in any smartphone, even ones that cost twice as much:

  • Display: 6.67-inch 3120 x 1440 Fluid OLED, 516ppi
  • Processor: Snapdragon 855
  • RAM: 6GB/8GB/12GB
  • Storage: 128GB/256GB
  • Battery: 4,000mAh
  • Colors: Nebula Blue, Mirror Gray, Almond

Three cameras are better than two

My full review of the OnePlus 7 Pro will be arriving later this week, but it already makes a strong first impression. Yes, it’s big, but the ultra-skinny bezels and curved edges keep the size quite manageable. The display is simply stunning, on par with the $1,000 handsets from Samsung and Apple. And it’s got one trick those other phones don’t have: a 90Hz refresh rate, so animations and gestures feel smoother and speedier than a normal 60Hz screen.

The OnePlus 7 is crazy-fast even when you’re not moving things around the screen. I’ve used a couple of phones with Snapdragon 855 processors, and the OnePlus 7 feels the fastest, thanks to the oodles of RAM and Oxygen OS, which continues to be among the best Android skins. It’s clean, minimal and intuitive, and includes all of the latest Android Pie features, including gesture navigation and Digital Wellbeing.

The OnePlus 7 Pro looks stunning in Nebula Blue, but you won’t find wireless charging inside.

And the there’s the camera. Cameras have been a bone of contention among OnePlus phones since their debut, but the OnePlus 7 seriously ups the game with its first triple-camera setup. Check out the specs:

New giant ‘radio galaxies’ help shed light on the history of the universe

Two giant radio galaxies have been discovered with South Africa’s powerful MeerKAT telescope, located in the Karoo region, a semi-arid area in the southwest of the country. Radio galaxies get their name from the fact that they release huge beams, or ‘jets’, of radio light. These happen through the interaction between charged particles and strong magnetic fields related to supermassive black holes at the galaxies’ hearts.

These giant galaxies are much bigger than most of the others in the Universe and are thought to be quite rare. Although millions of radio galaxies are known to exist, only around 800 giants have been found. This population of galaxies was previously hidden from us by radio telescopes’ limitations. But the MeerKAT has allowed new discoveries because it can detect faint, diffuse light which previous telescopes were unable to do.

Our discovery, published in the Monthly Notices of the Royal Astronomical Society, gives astronomers further clues about how galaxies have changed and evolved throughout cosmic history. It’s also a way to understand how galaxies may continue to change and evolve – and even to work out how old radio galaxies can get.

The giant radio galaxies were spotted in new radio maps of the sky created by one of the most advanced surveys of distant galaxies. The team working on it has included astronomers from around the world including South Africa, the UK, Italy, and Australia. Called the International Gigahertz Tiered Extragalactic Exploration (MIGHTEE) survey, it involves data collected by South Africa’s impressive MeerKAT radio telescope. MeerKAT consists of 64 antennae and dishes and started collecting science data in early 2018. It will ultimately be incorporated into the Square Kilometer Array, an intergovernmental radio telescope project spearheaded by Australia and South Africa.

The galaxies in question are several billion light-years away. The discovery of enormous jets and lobes in the MIGHTEE map allowed us to confidently identify the objects as giant radio galaxies.

Their discovery means that a clearer understanding of the evolutionary pathways of galaxies is beginning to emerge. This is tantalizing evidence that a large population of faint, very extended giant radio galaxies may exist. This may help us understand how radio galaxies become so huge and what sort of havoc supermassive black holes can wreak on their galaxies.

What’s new

Many galaxies have supermassive black holes in their midst. When large amounts of interstellar gas start to orbit and fall into the black hole, the black hole becomes ‘active’: huge amounts of energy are released from this region of the galaxy.

In some active galaxies, charged particles interact with the strong magnetic fields near the black hole and release huge beams, or ‘jets,’ of radio light. The radio jets of these so-called ‘radio galaxies’ can be many times larger than the galaxy itself and can extend vast distances into intergalactic space. Think of them like jets of water from a whale’s blowhole, a thin column extending into a cloudy plume at the end.

We found these giant radio galaxies in a region of sky that’s about four times the area of the full Moon. Based on what we currently know about the density of giant radio galaxies in the sky, the probability of finding two of them in a region this size is extremely small – only 0.0003%. So, it’s possible that giant radio galaxies – those that emit the beams, or jets of light described above – may actually be more common than we previously thought.

These aren’t the first radio galaxies astronomers have discovered. Many hundreds of thousands have already been identified. But only around 800 have radio jets bigger than 700 kilo-parsecs in size, or around 22 times the size of the Milky Way. These truly enormous systems are called ‘giant radio galaxies’.

Our new discoveries are more than 2 Mega-parsecs across: about 6.5 million light years or about 62 times the size of the Milky Way. Yet they are fainter than others of the same size. That’s what makes them harder to see.


We suspect that many more galaxies like these should exist, because of the way we think galaxies should grow and change over their lifetimes. And that’s one question we hope this discovery can help to answer: how old are giant radio galaxies and how did they get so enormous?

Now, telescope technology is making it possible to put these and other theories to the test. MeerKAT is the best of its kind in the world because of the telescope’s unprecedented sensitivity to faint and diffuse radio light. This capability is what made it possible for us to detect the giant radio galaxies. We could see features that haven’t been noticed before: large-scale radio jets coming from the central galaxies, as well as fuzzy cloud-like lobes at the end of the jets.
