A Rorschach Aurora
29.10.2021

If you see this as a monster's face, don't panic. It's only pareidolia, often experienced as the tendency to see faces in patterns of light and shadow. In fact, the startling visual scene is actually a 180 degree panorama of Northern Lights, digitally mirrored like inkblots on a folded piece of paper.

Northern Lights and Noctilucent Clouds
20.06.2018

Skies after the near-solstice sunset on June 17 are reflected in this calm lake. The tranquil twilight scene was captured near Bashaw, Alberta, Canada, northern planet Earth. Usually spotted at high latitudes in summer months, night shining or noctilucent clouds hang just above the horizon, transfusing light into a darker sky.

13.11.2025

Northern lights have come to Florida skies. In fact, the brilliant streak of a Northern Taurid meteor flashes through the starry night sky above the beach in this sea and skyscape, captured from Shired Island, Florida on November 11. Meteors from the annual Northern Taurid meteor shower are expected this time of year.

Spiral Sunspot

Spiral galaxies abound in the universe, but spiral sunspots are definitely an unusual twist. This distinctive spiral-shaped sunspot caught the attention of National Solar Observatory astronomers and was photographed on February 19, 1982 with the Vacuum Solar Telescope on Kitt Peak.

Aurora s Ring

Gusting solar winds and blasts of charged particles from the Sun made the early days of October rewarding ones for those anticipating aurora. While out enjoying the stormy space weather from Toemmeraas, Norway, Trygve Lindersen recorded this picturesque apparition of the northern lights with a digital camera on October 6.

Naked Eye Comet ZTF
20.01.2023

Comet C/2022E3 (ZTF) is no longer too dim to require a telescope for viewing. By January 19, it could just be seen with the naked eye in this rural sky with little light pollution from a location about 20 kilometers from Salamanca, Spain.

Sunspots on a Cloudy Day
4.06.2009

On June 2nd, clouds over Stuttgart, Germany parted to reveal what has become a relatively rare sight, spots on the Sun. In fact, the roughly 11-year solar activity cycle is still in a surprisingly deep minimum and the years 2008 and 2009 have had the lowest sunspot counts since the 1950s.

Coronal Hole

This ominous, dark shape sprawling across the face of the active Sun is a coronal hole -- a low density region extending above the surface where the solar magnetic field opens freely into interplanetary space.

Planet Aurora Borealis
28.01.2012

Illuminated by an eerie greenish light, this remarkable little planet is covered with ice and snow and ringed by tall pine trees. Of course, this little planet is actually planet Earth, and the surrounding stars are above the horizon near Östersund, Sweden.

Wind and spaceweather are transformed in this haunting night skyscape. The prairie windmill and colorful auroral display were captured on October 1, from central South Dakota, USA, as a good season for aurora hunters came with longer autumn nights.
