Swan Nebula

The Swan Nebula (also known as the Omega Nebula) is 5,000 to 6,000 light years away and is one of the largest star-forming areas in our galaxy. NASA recently released this image of the nebula obtained from the SOFIA Telescope.

Uncovering the nebula’s secrets is no simple task. It’s located more than 5,000 light years away in the constellation Sagittarius. Its center is filled with more than 100 of the galaxy’s most massive young stars. These stars may be many times the size of our Sun, but the youngest generations are forming deep in cocoons of dust and gas, where they are very difficult to see, even with space telescopes. Because the central region glows very brightly, the detectors on space telescopes were saturated at the wavelengths SOFIA studied, similar to an over-exposed photo. SOFIA’s infrared camera called FORCAST, the Faint Object Infrared Camera for the SOFIA Telescope, however, can pierce through these cocoons.

Elgato 4K60 S+ Video Capture With SD Card

For the past 7 years I’ve been using the Avermedia Live Gamer Portable to capture gameplay footage directly to an SD card. I like the ability to record gameplay footage from my consoles or gaming computer without needing a second computer to capture the footage.

The Avermedia LGP is starting to show its age, however, with its limit of recording a maximum resolution of 1080p.

Corsair recently announced its 4K60 S+ which will capture 4KHDR video at 60FPS directly to an SD card.

Threema–Secure Messaging Without Registering a Phone Number or Email Address

I had never heard of Threema before, but it popped up in a list of secure messenger applications that doesn’t require a phone number or email address.


Threema end-to-end encrypts all your communication, including messages, voice calls, group chats, files and even status messages. Only the intended recipient, and nobody else, can read your messages. Threema uses the trusted open source NaCl cryptography library for encryption. The encryption keys are generated and safely stored on user’s’ devices to prevent backdoor access or copies.

. . .


Each Threema user receives a random Threema ID for identification. A phone number or email address is not required to use Threema. This unique feature allows you to use Threema completely anonymously – no need to give up private information or to open an account.

It looks like the biggest concern with Threema’s security model is the fact that its source code is closed source.


AnonAddy.com is an anonymous email forwarding tool.

First, you create a username which is then used to create a subdomain such as “randomuser.johndoe.anonaddy.com”. If you don’t want the username revealed, you can also generate UUID aliases

You can then create aliases on the fly to use as email addresses when signing up at sites or for sending emails. The forwarding email address acts as a catchall so you can have an unlimited number of unique email addresses (I use something like this with another service so I can use a unique email address for every service).

Emails sent to any of those aliases get forwarded on to whatever email address you’ve designated.

The paid versions of AnonAddy.Com also allow users to set up custom domain names and additional usernames.
