Climate change and increasing urbanization are causing more and more heat, which is particularly noticeable these days. Locals and tourists are therefore looking for ways to avoid direct sunlight. Of course you can change sides of the road, but this is not always possible – and Google Maps doesn’t offer any help.

The “vampire routing” proof-of-concept, also known as “vampire mode”, solves this problem with a new type of technology. It suggests footpath routes that preferably run in the shade – just like vampires that avoid the sun at all costs. A small detour can also be accepted.

This otherworldly, ever-changing landscape is what the Sun looks like up close. ESA’s Solar Orbiter filmed the transition from the Sun’s lower atmosphere to the much hotter outer corona. The hair-like structures are made of charged gas (plasma), following magnetic field lines emerging from the Sun’s interior.

The brightest regions are around one million degrees Celsius, while cooler material looks dark as it absorbs radiation.

This video was recorded on 27 September 2023 by the Extreme Ultraviolet Imager (EUI) instrument on Solar Orbiter. At the time, the spacecraft was at roughly a third of the Earth’s distance from the Sun, heading for a closest approach of 43 million km on 7 October.

On the same day that this video was recorded, NASA’s Parker Solar Probe skimmed just 7.26 million km from the solar surface. Rather than directly imaging the Sun, Parker measures particles and the magnetic field in the Sun’s corona and in the solar wind. This was a perfect opportunity for the two missions to team up, with ESA-led Solar Orbiter’s remote-sensing instruments observing the source region of the solar wind that would subsequently flow past Parker Solar Probe.

Spot the moss, spicules, eruption and rain
Lower left corner: An intriguing feature visible throughout this movie is the bright gas that makes delicate, lace-like patterns across the Sun. This is called coronal ‘moss’. It usually appears around the base of large coronal loops that are too hot or too tenuous to be seen with the chosen instrument settings.

As of June 2020, NASA’s Solar Dynamics Observatory — SDO — has now been watching the Sun non-stop for over a full decade. From its orbit in space around the Earth, SDO has gathered 425 million high-resolution images of the Sun, amassing 20 million gigabytes of data over the past 10 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system.

We have now seen the smallest details on the largest object in the solar system,” said Inouye telescope director Thomas Rimmele during a January 24 news teleconference.

Covering an area 36,500 kilometers across — roughly three times the diameter of Earth — the images show familiar bubbles of plasma percolating up from the depths. In the dark lanes between the bubbles, newly resolved clusters of bright points appear at the roots of magnetic fields that stretch out into space.

„It’s always shining, always ablaze with light and energy. In the ubiquity of solar output, Earth swims in an endless tide of particles. Every time half of the Earth faces the Sun, we experience the brightness of daytime, the Sun’s energy and light driving weather, biology and more. But in space, NASA’s Solar Dynamics Observatory (SDO) keeps an eye on our nearest star 24/7. SDO captures images of the Sun in 10 different wavelengths, each of which helps highlight a different temperature of solar material. In this video we experience images of the Sun in unprecedented detail captured by SDO. Presented in ultra-high definition video (4K) the video presents the nuclear fire of our life-giving star in intimate detail, offering new perspective into our own relationships with grand forces of the solar system.“

This montage features excerpts of 4K full-disk pictures in extreme ultraviolet channels,
mainly using wavelengths of 30.4 nm (50,000 Kelvin) partially in combination with 17.1 nm (6.3×105 Kelvin),
and offers a glance at spicules, solar flares, filaments and an overview of the sun’s atmosphere.
The footage was captured by the Atmospheric Imaging Assembly (AIA) maintained by the Joint Science Operations Center
(Lockheed Martin Solar and Astrophysics Laboratory in collaboration with Stanford University)

We showed people what they looked like in ultraviolet, & wondered aloud if they wanted to put on some damn sunscreen already.
