In Pictures: Euclid sends back first test images

The first test images produced by ESA’s Euclid probe are here and hint at the amazing power of the imaging power on board.

These test images are simply just that – future images will be even more detailed and much sharper and cleaner.

The Euclid Telescope has been built and designed by ESA and the Euclid Consortium to explore the evolution of the dark universe, discovering how it formed and expanded over time.

In order to do this, it has been fitted with a 1.2m-diameter telescope, visible-wavelength camera, and near-infrared camera/spectrometer. Using these instruments, Euclid will build a detailed 3D map of the Universe – the third dimension being time.

During its mission, Euclid aims to answer some pretty big questions, such as if the expansion of our Universe is uniform or whether it changes over time. And whether or not our understanding of gravity is complete and accurate.

One of the images released shows spiral and elliptical galaxies, nearby and distant stars, star clusters, and cosmic rays as they shoot across space.

This image was taken to test the camera once Euclid came online. Once the instruments are fully configured, future images will show these stars and galaxies in much more detail and with much sharper quality.

This second image was taken with the VISible instrument (VIS) and shows the Universe in visible light. This is just one section from the 38 detectors onboard Euclid.

The spacecraft is named after the Greek mathematician Euclid of Alexandria, who lived in ancient Greece at around 300 BC. He is believed to be the father of geometry, therefore the mission was named in his honour.

Why it’s completely normal for a phone call to fill you with dread (and how to get over it)

Image
We spend most of our day palming our phone. We even get nervous when we can’t find it. So why is it that when it actually comes to using a phone for its primary function, to make phone calls, many of us are shying away? In fact, one survey of UK office workers found that 40 per cent of baby boomers and 70 per cent of millennials experience anxious thoughts when the phone rings . Gen Z are so prone to ignoring phone calls, they’ve even been called ‘generation mute’ by some. Talking in real time can feel scarier than commenting on social media or sending messages via WhatsApp, and ‘social anxiety’ is a growing problem, with 15 million Americans currently suffering . Telephone phobia (or ‘telephobia’) is the reluctance or fear of making or taking phone calls and although it’s been around for almost as long as there have been phones (the poet Robert Graves wrote about a fear of using the telephone in 1929), cases are officially on the rise. At the moment, most evidence suggests this i
