At present, the formation of galaxies is difficult to understand without the presence of a ubiquitous, but mysterious component, termed dark matter. Astronomers have measure how much dark matter there is around galaxies, and have found that it varies between 10 and 300 times the quantity of visible matter. However, a few years ago, the discovery of a very diffuse object, named Dragonfly 44, changed this view. It was found that this galaxy has 10,000 times more dark matter than the stars. Taken back by this finding, astronomers have made efforts to see whether this object is really anomalous, or whether something went wrong in the analysis of the observations. Now we have the answer.
An international team led by the Kapteyn Institute of the University of Groningen (the Netherlands), with participation by the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), has found that
Samsung’s Galaxy A51 5G is currently the South Korean giant’s cheapest 5G offering in the market. That is about to change soon as the company has now announced an even more affordable Galaxy A42 5G smartphone. Samsung announced the Galaxy A42 5G on its UK website. The company’s Vice President of Sales in UK and Ireland said that it is a part of Samsung’s ongoing efforts to deliver next-generation connectivity to more people.
The Samsung Galaxy A42 5G will be priced at GBP349 (roughly Rs. 33,400) in the UK, that puts it below the Galaxy A51, which comes with the sticker price of GBP429 in the country (roughly Rs. 41,100). The Galaxy A42 5G will be powered by the recently-launched Qualcomm Snapdragon 750G processor, which is said to be a step up from the
With the Covid-19 pandemic still raging and the economy battered, many consumers are likely to be tightening their purse strings.
Perhaps keeping that in mind, Samsung has delivered a “lite” flagship smartphone – the Galaxy S20 FE 5G. This “Fan Edition” gets a $800 price cut from the flagship S20 Ultra ($1,898) launched in March.
This means Samsung had to shed some features from the S20 Ultra. The phone comes with 8GB of system memory (instead of 12GB found in the S20 Ultra), a lower-resolution display (2,400 x 1,080 pixels instead of 3,200 x 1,400 pixels), a plastic rear (instead of Gorilla Glass) and an optical in-display fingerprint sensor (instead of an ultrasonic one).
The camera also gets a downgrade. The S20 FE features a rear triple-camera system instead of S20 Ultra’s quad-camera system that comprises a high-resolution 108-megapixel (MP) wide-angle camera. The S20 FE’s telephoto camera has only a
Samsung today, in an official press room release, unveiled its most affordable 5G smartphone, called the Galaxy A42 5G. The phone has tons of features and decent specs under the hood.
Samsung has been on a roll this year, with the release of new smartphones. We have got Galaxy S20 series, Note 20 series, Galaxy Z Flip, Galaxy Z Fold 2, and tons of mid-rangers in between all of this.
And now, as per new reports, Samsung has taken the wraps off its latest device, the Galaxy A42 5G. The phone has multiple cameras, a fast-charging battery, infinity-U display, and on top of that, 5G support.
Basically, it covers its bases alongside being a 5G phone. This is something that users expect out of a Galaxy A series phone. Samsung has been committed to bringing next-gen connectivity devices to its users and hence, the Galaxy A42 5G.

Amazon Prime Day 2020 officially starts up on Tuesday, Oct. 13 — the same day Apple is expected to launch the iPhone 12. While you’re not going to find any discounts on the new iPhone on Amazon, you could very well see some slashed prices on older models like the iPhone 11, along with deals on plenty of phones from other major manufacturers.
Last year, Prime Day meant deep discounts on flagship phones like the Moto Z3 Play, the Samsung Galaxy S10 and the Google Pixel 3XL. Amazon has already trotted out a bunch of sales before Prime Day officially starts, and during this stretch of time, everything from Alexa devices to laptops and TVs is discounted.
Here are the best early Amazon Prime Day phone deals we’ve found so far — plus one where Best Buy beats Amazon by $5. Note that prices and availability were accurate at
Read: The absurdity of the Nobel Prizes in science
Black holes are among the most mysterious phenomena in the universe. Forged from the cores of dead stars, they are so dense that nothing can escape their gravitational pull, not even light, which renders them invisible. Entire stars, once luminous, can be extinguished if they cross a black hole’s boundary, and pass the point of no return.
Albert Einstein predicted more than a century ago, based on his theories untangling the nature of gravity, that such strange objects could exist, but he thought the idea was too far-fetched. In 1965, after Einstein’s death, Penrose, the Oxford professor, published a paper showing, mathematically, that the forces of the universe could indeed produce black holes, and that inside their impenetrable depths resides something called a singularity, an inscrutable point which no known laws of physics can describe.
For US astronomer Andrea Ghez, who won this year’s Nobel Physics Prize, what makes black holes so fascinating is how tricky they are to conceptualize.
If she’s asked to explain them to an average person, her standard answer is: “A black hole is an object whose pull of gravity is so intense that nothing can escape it — not even light.”
That doesn’t always satisfy people’s curiosity.
“Very few people understand what a black hole is — but I think so many people are fascinated by them,” the professor at the University of California, Los Angeles told AFP by phone after she was co-awarded this year’s prize, along with Roger Penrose of Great Britain and Reinhard Genzel of Germany.
This summer, Ghez’s team celebrated the 25th anniversary of the start of their project, using a massive telescope in Hawaii, new optical technologies and innumerable calculations to measure the supermassive black
Samsung has reportedly decided against offering an in-display selfie camera on the Galaxy S30 series.
It’s believed that the Galaxy Z Fold 3 will be the first Samsung device with this tech instead.
We’ve already seen the first couple of phones with an in-display selfie camera launching this year, with the ZTE Axon 20 leading the charge. The technology allows for a proper full-screen display, as the camera is hidden below the screen.
Now, Korean outlet The Elec reports that Samsung has decided against offering an in-display selfie camera on the Galaxy S30 series (aka the Galaxy S21 family). The publication reports that Samsung has suffered from low production yields of the technology.
Instead, the Galaxy S30 phones will reportedly pack a center-mounted punch-hole cutout once again, as we saw with the Galaxy S20 series, Galaxy Note 20 series, and Galaxy Note 10 family. We won’t have to wait too
