Queen Elizabeth II posted a photo for the first time ever via Kensington Palace’s Instagram account.

On Wednesday, the 92-year-old monarch shared an image and personal message with the royal family to help promote the Science Museum in London. The photo features a letter from the 19th century inventor and mathematician Charles Babbage to Queen Victoria and Prince Albert.

“Today, as I visit the Science Museum I was interested to discover a letter from the Royal Archives, written in 1843 to my great-great-grandfather Prince Albert. Charles Babbage, credited as the world’s first computer pioneer, designed the ‘Difference Engine,’ of which Prince Albert had the opportunity to see a prototype in July 1843,” the letter read.

The lengthy post was signed “Elizabeth R,” which confirms that it was a post made by Her Majesty. Instagram also acknowledged the Queen’s use of its platform by commenting “Yes Queen” on her post with a crown emoji.

Meanwhile, the monarch has also used Twitter for the first time in 2014. At that time, the Queen’s tweet was also in support of the Science Museum.

“It is a pleasure to open the Information Age exhibition today at the @ScienceMuseum and I hope people will enjoy visiting. Elizabeth R,” the tweet read.

The Queen’s tweet was posted via the Royal Family’s official Twitter account.

According to The Guardian, Prince Philip and Her Majesty arrived at the Science Museum in London to open and tour the UK’s first parliament gallery dedicated to the history of information and communications technology.

In related news, the Queen also made headlines this week after it was revealed that she once lost her temper at Prince William. In 2016, Prince William was at the Buckingham Palace balcony for the Queen’s birthday celebration when he decided to kneel down while talking to Prince George.

When Her Majesty noticed what Prince William was doing, she tapped on her grandson’s shoulder and urged him to get up. Prince William immediately followed his grandmother’s order and he stood up.
