Aurora over Raisting Earth Station - From Simeon Schmauß (stim3on.bsky.social) - https://flic.kr/p/2pQvMHo

What a crazy night, we went into it not expecting much since the solar storm was forecast for after sunrise in central Europe.
However, before the sun had even set, I got the alert that the first CME had impacted Earth, so the chances immediately looked a lot better. What then unfolded surpassed even our wildest expectations.
We ended up driving to this satellite ground station south of Ammersee in southern Bavaria and just when we arrived we spotted the first diffuse pillars north of us.
We experienced three waves of incredibly strong Aurora, especially for our rather Southern latitude. During the second wave we saw individual pulsating filaments dancing over our heads. What a breathtaking experience!

Many thanks to Christopher for accompanying me on this adventure, Max for being an all round great guy, and Sebastian who lent me his wide angle lenses that made these shots possible.

Views of a famous pulsating star taken nearly 90 years apart and a portrait of its galactic home are shown in this image collection.

The pancake-shaped disk of stars, gas, and dust that make up the Andromeda galaxy, or M31, is shown in the image at left. Andromeda is a Milky Way neighbor and resides 2 million light-years away.

The tiny white box just above center outlines the Hubble Space Telescope view. An arrow points to the Hubble image, taken by the Wide Field Camera 3. The snapshot is blanketed with stars, which look like grains of sand.

The white circle at lower left identifies Hubble variable number one, or V1, the Cepheid variable star discovered by astronomer Edwin Hubble in 1923. Cepheid variables are pulsating stars that brighten and fade in a predictable pattern. Astronomers use them to calculate how far away they are from Earth.

The large white box outlines the region imaged by astronomer Edwin Hubble, who used the 100-inch Hooker telescope, the most powerful telescope of that era. An arrow points to a copy of Hubble's image of Andromeda, which was made on a 4-inch-by-5-inch glass plate and dated Oct. 6, 1923.

Edwin Hubble originally identified three novae, a class of exploding star, by writing "N" next to each object. Later, Hubble realized that the nova at top right was actually a Cepheid variable. He crossed ou...

Venus - Akatsuki - From Aster Cowart (terrasabaea.bsky.social) - https://flic.kr/p/DUVaRB

Venus as seen by Japan's Akatsuki space probe on September 5, 2016. At the time this photo was taken, Akatsuki was located approximately 60,000 km above the Venusian cloud tops.

This image was assembled using near-UV and near-IR photos to create a pseudo-true color view. My procedure for creating this image exaggerates the coloration and detail visible in the clouds, which show very little detail in the visible portion of the spectrum.

This photo has been further enhanced by showing the cloud patterns on the night side using an infrared image at 2.26 μm. This portion of the image uses a relative colormap to highlight some of the variation present.

At 2.26μm, Venus' clouds are partially transparent, allowing heat from the lower portions of the atmosphere to radiate into space. Dark regions in this part of the image are, in effect, shadows of clouds in the upper atmosphere near the same level as the visible clouds.

Mariner 9 mosaic of Olympus Mons. This is the spacecraft's first clear view of a dark albedo feature that was shrouded by dust during the spacecraft's arrival at Mars. As the dust cleared, it was revealed that this feature, known to terrestrial astronomers as Nix Olympica, was a massive volcano towering above the surrounding plains.

This mosaic was taken over two orbits, Revs 146 and 148, on March 8, 1972.

Anyone Else Think This Looks Like the Cookie Monster? - From Goddard Space Flight Center - https://flic.kr/p/diZy4d

NASA image acquired August 29, 2012

Ok, so maybe it's just me. But the superposition of younger craters on older craters (in this case two smaller craters upon the rim of an older crater) can result in landforms that appear to resemble more familiar shapes to human eyes. More generally, the Law of Superposition allows scientists to determine which surface features pre- and postdate others, leading to a better understanding of the geological history of different regions of Mercury's surface.

This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week.

The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet.

The Colours of Omega Centauri - From Rolf Wahl Olsen - https://flic.kr/p/ciBufb

Omega Centauri is by far the most massive of the about 150 known globular clusters in the Milky Way. Some 10 million stars orbit the center of this cluster. It is also relatively nearby which alltogether makes it a most impressive sight.
The cluster spans about 150 light years across, and is located some 15,000 light years away in the southern constellation Centaurus. It is easily visible to the naked eye and was first cataloged as a star by earlier astronomers.

In this image I have focused on bringing out the different colours of the stars in this massive globular. The cluster consists mainly of old red giant stars with a sprinkling of very conspicous blue stars. These are 'blue stragglers', stars that are too hot and massive for the cluster's otherwise old age. Given the ancient origin of the cluster these stars should have turned into red giants by now but it has been proposed that they are the results of mergers and mass transfers in the crowded environment of globular clusters. A main sequence star can exist for billions of years in the cluster and then later gain mass from a close orbiting binary, or as a result of a collision/merger, and thereby become more massive and hotter so that it now appears as a blue giant.

Antennae Galaxies collaboration: Ultra-Deep High Resolution View - From Rolf Wahl Olsen - https://flic.kr/p/r2XHAw

The Deepest and Highest Resolution View of the Entire Antennae Galaxies

This image is a collaboration between astrophotographers Federico Pelliccia of Italy and Rolf Wahl Olsen of New Zealand and shows an ultra-deep and detailed view of the famous Antennae colliding galaxies in Corvus.

The image was constructed from a number of sources: First a mosaic of panels from the 8.2m Subaru telescope was very patiently put together by Federico Pelliccia. This data was subsequently blended with Rolf Wahl Olsen's Antennae Galaxies Extreme Deep Field - 75 Hours to bring out the faint tidal streams and large scale structures which was not present in the high resolution Subaru data and this deep image also provided the colour information. The core was further enhanced by overlaying an extremely detailed frame from the Hubble Space Telescope.

Together this data represents the deepest and highest resolution view available to date covering the entire Antennae galaxies.

A double discovery - From Goddard Space Flight Center - https://flic.kr/p/XsvG5L

The galaxy, NGC 178 may be small, but it packs quite a punch. Measuring around 40,000 light-years across, its diameter is less than half that of the Milky Way, and it is accordingly classified as a dwarf galaxy. Despite its diminutive size, NGC 178 is busy forming new stars. On average, the galaxy forms stars totaling around half the mass of the Sun per year — enough to label it a starburst galaxy.

The galaxy’s discovery is an interesting, and somewhat confusing, story. It was originally discovered by American astronomer Ormond Stone in 1885 and dubbed NGC 178, but its position in the sky was recorded incorrectly — by accident the value for the galaxy’s right ascension (which can be thought of as the celestial equivalent of terrestrial longitude) was off by a considerable amount.

In the years that followed NGC 178 was spotted again, this time by French astronomer Stéphane Javelle. As no cataloged object occupied that position in the sky, Javelle believed he had discovered a new galaxy and entered it into the expanded Index Catalog under the name IC 39. Later, American astronomer Herbert Howe also observed the object and corrected Stone’s initial mistake. Many years later, astronomers finally noticed that NGC 178 and IC 39 were actually the same object!

This image of NGC 178 comprises data gathered by the Wide Field Planetary Camera 2 aboard the NASA/ESA Hubble Space Telescope.

Graben and Lava Flows - From UAHiRISE (NASA) (uahirise.bsky.social) - https://flic.kr/p/2niHzS1

These fresh looking lava flows east of Arsia Mons that appear bright in THEMIS daytime infrared pictures are crosscut by a circumferential graben. (A graben is a depression that forms between two parallel faults.) A CaSSIS image shows a bright deposit following the fault scarp on the hanging-wall of the western fault. HiRISE can characterize this deposit at higher resolution than other instruments like CaSSIS and the Context Camera.

Image is less than 5 km (3 mi) across and is 253 km (157 mi) above the surface. For full images including scale bars, visit the source link.
