I had to, it’s like the biggest sporting event going and I’m not about to miss out! YAY football!
The Netherlands and Germany look pretty tough!

Nice! The Saturn moon Atlas, not one we often get to see. Atlas was discovered in 1980 thanks to the Voyager spacecraft and JPL employee Richard Terrile. As moons go Atlas is tiny being only around 30 km (18 miles) in diameter.
From the Cassini site:
The Cassini spacecraft captures a glimpse of the moon Atlas shortly after emerging from Saturn’s shadow. Although the sunlight at Saturn’s distance is feeble compared to that at the Earth, objects cut off from the Sun within Saturn’s shadow cool off considerably.
Scientists study how the moons around Saturn cool and warm as they enter and leave Saturn’s shadow to better understand the physical properties of Saturn’s moons.
This view looks toward the sunlit side of the rings from about 44 degrees above the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 23, 2014.
The view was acquired at a distance of approximately 1.6 million miles (2.6 million kilometers) from Atlas and at a Sun-Atlas-spacecraft, or phase, angle of 93 degrees. Image scale is 10 miles (16 kilometers) per pixel.

Another stunning image from the Hubble!
NGC 3081 is about 34.3 Mpc away (that’s about 112 Million light-years!) in the constellation of Hydra. There are two People credited with the discovery of this galaxy: by William Herschel on 21 Dec 1786 and later listed as NGC 3081, and by Lewis Swift on 11 Apr 1898 and later listed as IC 2529. The internet was slower back then. Just kidding, it’s not at all far fetched to have independent discoveries.
NGC and IC are both catalogs. IC is for the Index Catalogue of Nebulae and Clusters of Stars which is an update to the New General Catalogue. NGC was put together in the 1880’s by John Dreyer using data from William and John Herschel (father and son). The Index Catalogue or IC was published in two sections by Dreyer in 1895 and 1908.
I think there are at around 7840 entries in the NGC.
ESA’s description (via NASA):
Taking center stage in this new NASA/ESA Hubble Space Telescope image is a galaxy known as NGC 3081, set against an assortment of glittering galaxies in the distance. Located in the constellation of Hydra (The Sea Serpent), NGC 3081 is located over 86 million light-years from us. It is known as a type II Seyfert galaxy, characterized by its dazzling nucleus.
NGC 3081 is seen here nearly face-on. Compared to other spiral galaxies, it looks a little different. The galaxy’s barred spiral center is surrounded by a bright loop known as a resonance ring. This ring is full of bright clusters and bursts of new star formation, and frames the supermassive black hole thought to be lurking within NGC 3081 — which glows brightly as it hungrily gobbles up in-falling material.
A few days ago you may recall there was an asteroid that passed by Earth. The asteroid passed about three times further from us than our moon. Yes that is quite a ways out, but compared to cosmic distances, pretty close.
NASA was able to get some great images of the more than 366 meter (1200 ft) long oblong shaped rock once it had passed. The video above was pieced together from images taken at a range of 1.25 and 1.39 million km (774,000 to 864,000 miles).
The images were captured by the 70-meter Goldstone antenna working with the Arecibo Observatory in Puerto Rico.
As an aside: Arecibo is located in a seismically active area being not far from the Caribbean plate boundary. Generally the quakes are fairly small, for example yesterday 14 June there was a magnitude 2.7 quake at a depth of 26 km (22.4 miles) occurred 75 km (47 miles) out in the ocean and that was among eight occurring in the previous 24 hours having magnitudes of 2.7 to 3.2. Sure those are pretty small but I wonder if they are noticed by the observatory especially during an observing run.
The same could be asked of the ESO and Keck now that I think of it, it’s just that Arecibo is so huge.
