The Hubble Space Telescope has captured a stunning image of a fan of dust and gas illuminated by a star that forms a structure called an emission nebula. This nebula, known as NGC 2313 or LDN 1653, is located around 3,750 light-years away in the constellation of Monoceros. Hubble captured the image using its Advanced Camera for Surveys (ACS) instrument, which looks in both the visible light and near-infrared wavelengths.

Emission nebulae are clouds of ionized gas that glow thanks to the illumination of stars within them. The stars give off radiation, which ionizes the gas and makes it glow. In this case, the bright star V565, located right in the center of the image, is illuminating the nebula and giving it its distinctive appearance.

You can also see four diffraction spikes around the star, which are a result of a phenomena called the starburst effect. Bright sources of light like stars appears to have spikes of light coming out of them due to the way the light is captured by telescopes. The right-hand side of the image is darker as there is a denser cloud of dust there which is not illuminated.

Nebulae with this type of shape were once referred to as a “cometary nebulae,” as the shape of a star followed by a fan of gas looked somewhat comparable to a comet and its tail of dust and gas that is visible when a comet approaches the sun. However, this name is rather confusing and inaccurate as these nebulae have nothing to do with comets, so the term is no longer used.

This is one example of the way that the language used to describe space phenomena changes as we learn more, as the Hubble scientists write: “The language that astronomers use changes as we become better acquainted with the universe, and astronomical history is littered with now-obsolete phrases to describe objects in the night sky, such as ‘spiral nebulae’ for spiral galaxies or ‘inferior planets’ for Mercury and Venus.”

Marvel confirms ‘Hawkeye’ and ‘Ms. Marvel’ are coming to Disney+ in 2021

Published

on

Halfway through July, this has already been one of the busiest years in the history of Marvel Studios. That makes it all the more incredible that we have seen less than half of the content that the studio has planned for 2021. In addition to the three new movies Marvel is releasing in the second half of the year, we also have confirmation that at least three new shows are coming to Disney+. After What If…? drops in August, Ms. Marvel and Hawkeye are still to come.

Speaking with Variety earlier this week, Marvel Studios EVP of film production Victoria Alonso revealed that “a few other shows” are on track for 2021, including Ms. Marvel and Hawkeye.

It’s worth noting that both Ms. Marvel and Hawkeye had already been slated for late 2021. Both the Ms. Marvel page and the Hawkeye page on Marvel’s official website state as much. That aside, Marvel has had very little to say about either show since announcing them in 2019.

What are Ms. Marvel and Hawkeye about?

While WandaVision, The Falcon and the Winter Soldier, and especially Loki helped to set up the stakes of the MCU’s Phase 4, Ms. Marvel and Hawkeye should be even more purposeful. Ms. Marvel will introduce us to Kamala Khan (Iman Vellani) ahead of 2022’s The Marvels. In Marvel comics, Kamala is a Pakistani-American and Carol Danvers fangirl that ends up getting powers of her own. She also takes her name from the powerful Avenger. Vellani will reprise her role in the sequel to Captain Marvel.

As for Hawkeye, we know that the show will bring Kate Bishop (Hailee Steinfeld) into the fold. She may very well take over for Jeremy Renner as an Avenger at some point in Phase 4. We also know from the Black Widow post-credits scene that Yelena Belova (Florence Pugh) will be involved.

Predictions for Marvel’s 2021 release dates

Here’s what we know about Marvel’s plans for its movies and shows for the rest of 2021: What If…? is coming to Disney+ on August 11th, Shang-Chi and the Legend of the Ten Rings arrives on September 3rd, Eternals follows on November 5th, and Spider-Man: No Way Home drops on December 17th.

Based on the fact that we saw some footage of Ms. Marvel last December, my guess is that it will start streaming on Disney+ in October. That leaves November as the only month left in the year without a Marvel Studios release. Therefore, I’m betting Hawkeye lands then.

Netflix is releasing 56 original movies and shows in August – here’s the full list

Published

on

Boy oh boy, has Netflix stepped it up recently or what? The streamer’s subscriber numbers from the last quarter weren’t very impressive. We have a feeling that’s due in no small part to the lack of compelling Netflix originals earlier this year. Long story short, Netflix’s movies and shows were beyond weak for the first few months of 2021. Now, however, things are really starting to pick up again. This past month alone, there were so many high-profile Netflix releases. You can see the full Netflix July releases list here. Highlights include Gunpowder Milkshake with Karen Gillan, the fantastic final season of Atypical, Virgin River season 3, and the Fear Street trilogy that horror fans loved. Now, however, it’s time to turn our attention to all the Netflix original releases in August 2021.

Wondering what Netflix subscribers have to look forward to next month? We’ll run down the full slate of new original releases right here.

Netflix original releases: August 2021

Netflix just announced all of its upcoming movie and series releases for August 2021. There are plenty of gems in there from third-party studios, but people are far more interested in original content. Netflix has been steadily raising its subscription fees every month, after all. Each time, it says the increase will help pay for new original content. With that in mind, subscribers want to know that they’re getting their money’s worth.

In August, Netflix has 56 new original movies, shows, and specials on tap. That’s down sharply from the 69 new originals spread out over July. Of course, quality is far more important than quantity. With that in mind, it’s time to see what kind of quality Netflix has in store.

Scroll down to check out the entire release calendar of Netflix originals in August. We’ve also included links to the relevant Netflix pages wherever possible. This way, you can set a reminder to be alerted when a title is released next month.

This free iPhone app is so incredible, it’s hard to believe it’s real

Published

on

If you need to order new contact lenses or a pair of glasses, many places won’t let you do so unless you take an eye test first. And seeing as how a trip to the optometrist can set you back as much as $200, many people put off getting their vision checked even when they should.

There is, however, an interesting alternative to popping into stores LensCrafters. Warby Parker recently issued an update to their Virtual Vision Test app for the iPhone. Now, users can take an eye test from the comfort of their own homes at a fraction of the cost of a traditional eye exam.

Today’s Top Deal Amazon’s #1 best-selling portable Bluetooth speaker is down to the lowest price of 2021! List Price:$34.99 Price:$22.09 You Save:$12.90 (37%) Buy Now Available from Amazon, BGR may receive a commission Available from Amazon BGR may receive a commission

How the mobile eye test works

With the new app, which was previously called Prescription Check, it’s now easier than ever for individuals to check their eyes and renew their glasses or contacts prescription.

Once you download the app, you can take a traditional eye exam. Open the app and you’ll be able to read letters off the iPhone from a distance of about 10 feet. Naturally, you’ll want to do this in a quiet and well-lit room.

If the app determines that your vision is good, which is to say that your prescription hasn’t changed, you’ll be charged $15 for a brand new prescription. And as mentioned above, this is vastly cheaper than the $200 you might otherwise be charged by taking a trip to the doctor or eyeglass store.

Don’t worry, a doctor is involved in the process

If you’re wary about leaving your eye test to a mysterious algorithm, you have nothing to worry about. Once your eye test is completed, an eye doctor will take a look and assess each individual’s results. In other words, the test itself is mobile, but the analysis is still handled by a professional.

App requirements

The app itself requires iOS 14.1 or later in order to run. And seeing as how iOS 15 is right around the corner, that shouldn’t be an issue for most users.

Additionally, the app is only available for the iPhone for the time being. At this point, there’s no indication in either direction if an Android app will be coming anytime soon.

Further, only individuals between the ages of 18 and 65 should use the app. Users experiencing problems with their current prescription shouldn’t use it either. You’ll also need a copy of your existing prescription on hand. The app notes that even an expired prescription will do.

If you’re curious about checking the app out, you can download it here from the App Store.
