Nasa shares an image of the area on Twitter or Instagram every time and explains what it is, many in the comments section ask how these photos were taken, whether the colours are real, and most importantly, they inquire about the cameras fitted with the Hubble telescope.  

The space company, in its newest put up on Instagram, stated it acquired that query usually and, subsequently, wished to interrupt it for area fanatics. To start with, NASA’s Hubble space telescope does not take a snapshot and get the picture to recolour, one thing a cell phone digital camera does.

 Nasa stated that Hubble’s camera would take photos of the wide range of wavelengths that come right down to earth in grayscale. This way is followed and adopted by scientists who use different colour filters in telescopes to take expressions, assign a colour to each filter relative to the wavelength, and combine colour images to create images.

 The area company stated that lots of the full-colour pictures shared by Hubble are created after combining three separate exposures — one every taken in crimson, inexperienced, and blue gentle.

“When mixed, these three colours can recreate almost any colour of light that is visible to human eyes,” NASA stated within the put up. “That’s how televisions, computer monitors, and video cameras recreate colours to show a picture!”

 Nasa stated while sharing an image of the ring nebula that the deep blue colour within the centre, represents helium, proven in seen gentle, the inside ring, proven in cyan colour, is the glow of hydrogen and oxygen, whereas the reddish outer ring is from nitrogen and sulphur.

Meanwhile, the space company shared two pictures of space on Twitter attached with “Hubble’s back!”

 One of the photographs reveals a three-armed spiral galaxy. NASA added within the caption, “after the Hubble team successfully turned on backup hardware aboard the telescope, the observatory got back to work over the weekend and took these galaxy snapshots.”

 

Microblogging platform Twitter has lost its legal indemnity in India because of its failure to comply with the new IT rules. The new rules required social media platforms to appoint key officers in the country. The loss of indemnity was highlighted on Tuesday after a case was filed against the social media giant over a viral video.

Government sources said that the platform is set to lose its intermediary status. Twitter is the only social media platform to not adhere to the rules, sources said. “Twitter to lose its status as an intermediary platform in India as it does not comply with new guidelines, it is the only social media platform among mainstream that has not adhered to new laws,” government sources said to news agency ANI. This means that Twitter is liable for penal actions as per Indian law.

“We are keeping the MeitY apprised of the progress at every step of the process. An interim Chief Compliance Officer has been retained and details will be shared with the Ministry directly soon. Twitter continues to make every effort to comply with the new Guidelines,” said a Twitter spokesperson on the development.

On Tuesday The instant messaging app WhatsApp is going to multi-device support and will be launching soon. Mark Zuckerberg revealed this during a chat with Wabetainfo. According to a popular website Wabetainfo which gives instant updates on messaging app Whatsapp made an announcement on Twitter about a new update.

The popular messaging app Whatsapp is expected to bring multi-device support for beta testing in the next couple of months which will support the end to end encryption. It is claimed that it will protect photos, videos, text, voice messages and documents in a way that they aren’t accessible by anyone except the sender and receiver. 

This is also the primary reason WhatsApp did not comply with the government of India’s new IT rules which demanded to find the originator of a message. In an argument finding the originator would mean circumventing the end-to-end encryption. It would make WhatsApp go against its own policies. 

This new feature by the messaging app will permit individuals to operate a similar WhatsApp account on various gadgets simultaneously. It will provide multiple devices protection alongside syncing communication between them is not that easy and involves technical challenges in its implementation.

Regarding the multiple device support, Zuckerberg said, ” It’s been a big technical challenge to get all your messages and content to sync properly across devices even when your phone battery dies, but we’ve solved this and we’re looking forward to getting it out soon.”

The multi-device support will also enable WhatsApp to expand to more form factors, including the Apple iPad. The iPad is expected to get its own version of the app soon. Multi-gadget with different devices will allow users to interface up to four unique gadgets to the user’s main WhatsApp account. 

The Facebook-owned company is purportedly reestablishing the green colour notifications for its Android beta application. It had announced a new dark blue colour in notifications a few days back in the 2.21.12.12 beta update but the users weren’t happy with the update so WhatsApp decided to restore the old colour. 

Alongside enabling end-to-end encryption when using multi-device support, WhatsApp is expected to bring end-to-end encrypted backups. There is, however, no exact timeline on when it would be available even for public beta testers. 

Other than these, WhatsApp will launch more features, Mark Zuckerberg himself has confirmed some features mentioned above. It is important to note that WhatsApp already has the disappearing messages feature but Mark talks about unveiling the disappearing mode.
